Summary of Modalities
The modalities of the present invention are related to a hair brush for detaching human hair or animal hair, which includes a field of bristles comprising at least 100, 150, 200 or 250 bristles, where a variety of heights is represented , for example, at least five heights that differ significantly from each other. The heights / extensions of the bristles in the bristle field (i) vary in a substantially random manner, and (ii) are substantially independent of the location of the bristle on the bristle retaining surface.
Optionally, in some embodiments, the bristles are preferably not of uniform width, instead a variety of bristle widths (e.g., three or more different bristle widths differing significantly from each other) are represented in the bristle field.
Alternatively or additionally, the bristles can be made of materials of different flexibility. Optionally, but, preferably in some embodiments, the longer / taller bristles are, on average, thicker than the shorter bristles and / or the longer / taller bristles are constructed of less flexible material than the shorter bristles.
A new hairbrush according to several features disclosed here was built and tested against a conventional “control” hairbrush. Specifically, the hair on one half of the head (that is, the left half or the right half) was untangled using the new brush, while the hair on the other half of the head was untangled using the control brush.
During untangling the hair, the hair was detached or pulled out of the user's head. The detached hair using the conventional and control brush (that is, when unloading regibes of considerable size hair) was collected separately and the amount of detached hair was measured and compared.
It was discovered that the new hairbrush that provides the characteristics disclosed here was able to detangle human hair (even though it was damp hair and / or hair that was not properly treated with conditioner), in a surprisingly painless way, and / or in a a way that, surprisingly, significantly induced less pain than when using a conventional brush. In addition, it was found that the amount of hair shedding when untangled using the new brush was significantly less than the amount of hair shedding when untied with the control brush (ie, again, when unpacking considerable-sized hair regions) .
It should be noted that during these tests / experiments, the user's real hair was actually untangled - this was not the situation where one of the brushes simply "massaged the user's head", without untangling or just untangling the outermost layers of hair.
Without looking for any connection with the theory, it should be noted that the hairs of the mammals are not of uniform length or of uniform thickness, instead, on the head of a person (or on the body of an animal), some hairs of hair are longer, others are shorter, some hairs are thicker and others are thinner. In addition, this spatial fluctuation in the length and / or thickness of the hair tends not to accompany any visible spatial pattern, unlike in many human or animal people, this fluctuation tends to be most of the time, or completely, random or stochastic. .
When using a brush that exhibits at least some of these random properties (i.e., a brush including a bristle field, where the length of the bristle and / or the thickness of the bristle and / or the flexibility of the bristle material varies substantially at random ), it is possible to untangle the hair in a reduced pain mode. Not wishing to be linked to any theory, it is postulated that the detachment of hair with reduced pain and / or reduced hair shedding that has been observed, is due to the fact that, at least partially, there is a certain amount of mechanical "compatibility". between the stochastic properties of the hairbrush and the stochastic properties of the hair of the human / mammal, in order to provide a technique of detachment of hair that is significantly less painful and / or, significantly, pulls smaller amounts of hair strands.
It should be noted that each bristle in the "bristle field" varies in height in a substantially random manner and is disposed substantially regardless of the location where it is implanted, i.e., each bristle is separated or individually implanted on the surface of the hairbrush. These individually implanted bristles contrast with bundles or tufts of bristles.
In the present description, height and length of bristle are considered and used as synonyms.
In the present disclosure, the terms bristle width and thickness are used interchangeably when referring to the width dimensioning feature. In the non-limiting case where the cross section of the bristle is circular (i.e., substantially cylindrical bristles), that width is the diameter of the circle.
In the present disclosure, when the bristle heights / lengths of a field of bristles “vary in a substantially random manner, which is substantially independent of the location of the bristle on the bristle retaining surface” (i) and it is possible to visualize the bristles together as a unit coherent or a “field”, and (ii) there is no visually determinable pattern (that is, different from randomness) for the length / height of the bristle, of the bristles of the bristle field.

The claims described in the annex will be better understood by referring to the present detailed description of examples of modalities, which are correlated to the figures. The description, modalities and figures should not be considered as limiting the scope of the claims. It should be understood that not all the characteristics of the methods and devices presently disclosed are necessary in each implementation. It should also be understood that through the current disclosure, in which a process or method is shown or described, the steps of the method can be performed in any order or simultaneously, unless, it is clear from the context, that one step depends on the other performed previously. As used throughout the present description, the word "can" is used in a permissive sense (ie, with the meaning of "having the potential of"), instead of a mandatory sense (ie, with the meaning of "must ”).
It should be noted that certain features of the present invention, which, for better understanding, are described in the context of separate modalities, can also be provided in combination in a single embodiment. In contrast, several features of the invention, which, briefly, are described in the context of a single embodiment, can also be provided separately or in any suitable subordinate combination.
When using a hairbrush, the surface of the “bristle end”, defined by the ends of the bristles, has irregular non-periodic properties (for example, having semi-random or random properties), and it is possible to detangle the hair in a relatively “Little pain” or in a “painless” way. In tests carried out under the supervision of the present inventor, it was discovered that the use of a hairbrush that provides “little pain” or “no pain” (that is, built according to the characteristics disclosed here and combinations thereof), reduces significantly the amount of time needed to untangle the hair of a human or animal (for example, the longest hair) and significantly reduce the amount of pain associated with untangling the hair, even for wet hair and / or hair wet that has not been properly treated with a conditioner.
Figures 1-2 show a non-limiting example of this new hairbrush for “unstuck with little pain”.
Without wishing to be linked to any particular theory, it is observed that, typically, the lengths of human hair are not the same, varying in some way in a random or semi-random model, despite the fact that the average hair length may be the same. even across the head or in regions of the head. The present inventor has postulated that it is possible to facilitate the detachment of relatively little pain and / or no pain by varying lengths and / or thicknesses and / or flexibilities of bristle material, in a substantially random manner across the retaining surface of hairbrush bristles, in order to imitate, at least partially, random or semi-random variations in hair length and / or thickness.
Thus, according to this line of reasoning, the hairbrush and, specifically, the shape of the “bristle end” surface defined by the most distant ends, presents a certain amount of disorder or entropy and, therefore, is “compatible” with the hair being disentangled. In addition, this bristle geometry (contrary to a situation in which the bristle lengths are constant or somehow "ordered"), can be useful in distributing tension or force of pull associated with untangling the hair, reducing the amount tension in any location.
In the present text and in the figures, a number of possible characteristics are disclosed. It should be noted that: (i) not all features are required in each modality; and (ii) any combination of features (i.e., all features or any subset of features, including combinations not explicitly listed in this document) can be provided in any embodiment shown.
Figures 1-2 illustrate a hairbrush according to some embodiments of the present invention. The hair brush (500) includes a brush body (510) and bristles implanted in a region (540) of the bristle retaining surface (530) of the brush body (510). In addition, the brush body includes a handle (520).
The most central portion of the region (540) is referred to by (560), while the "border portion" of the region (540) is referred to by (570). An “inner field” of bristles is available in this more central portion (560); an “external field” of bristles is available in the edge portions (570).
Figure 2 is now referenced. In figure 2, the “bristle end surface” (illustrated by the dotted line), defined by the furthest ends of the bristles, is illustrated. The term bristle end surface (550) does not require any extra material other than the bristle material itself, on the contrary, this term describes the surface that can be interpolated from the ends of the bristles.
An important feature of this bristle end surface (550) within the most central portion (560) of the bristle retaining surface (530) is that the bristle end surface (550) is irregularly formed, substantially without any observable periodicity, and with clearly observable stochastic or random properties.
Not wishing to be connected with any theory, it is observed that the hair itself can define a "surface of hair", defined by the ends of the hair and / or portions of hair strands that are the "highest" above the surface of the skull. This "surface of hair" (not shown) can also provide a certain level of semi-randomness or randomness or disorder or entropy, especially when the hair is messed up. It is postulated that due to the fact that the most distant end surface (550) provides these non-periodic or semi-random or random properties (similar to the “hair surface”), a better penetration of the bristles was facilitated within the surface. of hair, in a way that does not induce strong forces of traction or tension.
As can be seen from figures IB and 2A, in the region (570) close to the edge of the bristle retaining surface, the bristles are shorter than in the most central region (560). This optional “external bristle field” (as opposed to the internal bristle field, whose bristles are located in the most central region (560)), can, in some modalities, facilitate the penetration of the internal field bristles into the user's hair, in a relatively “soft” way. Thus, for example, many users brush their hair with a brush stroke, so that the outer region (570) of the hairbrush near the edge meets / contacts the hair, before the inner region (560) of the brush. In this case, first, the shorter bristles from the outer region will first find the hair, and then, the larger “more aggressive” bristles (for example, for unstuck) will immediately follow.
An important feature of the hairbrush shown in figures 1 and 2 is that most of the “bristle-populated” or “bristle-covered” portion of the hairbrush (in the example of figures 1 and 2, referred to by regions (560) and (570)) and configured so that some type of random pattern is dominant in that "most part", that is, a pattern of substantially random height and / or a pattern of substantially random width and / or a pattern of flexibility of substantially random material. In the case of figure IB, this represents a substantial majority, as the area of the external field (570) is much smaller than the area of the internal field (560). In the case of figure 9, this represents substantially the entire area. In different modalities, this "majority" or "majority" can be a substantial majority, for example, being at least 60%, at least 70%, at least 80%, at least 90%, at least 95% or substantially 100%.
In the case of varying material flexibility, the bristles can be made of materials of different flexibility (for example, some bristles are made of one type of material, such as plastic, other bristles are made of another type of material having a different flexibility, such as, another type of plastic, and still other bristles are constructed of another type of material having another different flexibility, such as, yet another type of plastic, etc., where at least 2, or at least 3, or at the minus 4, or at least 5, or any number of bristle materials can be used).
In the course of the present disclosure, the term "internal field" of bristles can refer to any field of bristles, whether or not there are additional fields of bristles arranged on the surface of the hairbrush. Thus, the bristle field having random height properties may or may not be provided with additional bristles.
It should be noted that the hairbrush shown in figures 1 and 2 is only idealized in an illustrative, by no means limiting way, however, in some embodiments, one or more common features of a hairbrush may be provided as shown in Figures 1 and 2, including, but not limited to, features that describe length properties, and / or features that describe bristle width properties, and / or features that describe a relationship between bristle location and length and / or bristle width.
The following is a brief list of some physical parameters related to the non-limiting example shown in figures 1 and 2, and in particular, the bristle field in the central region (referred to as the “internal bristle field”). This list is provided below, after the definitions section. It should be noted that any combination of features can be provided: (i) bristle count - in the examples in figures 1 and 2, the internal bristle field has about 300 bristles. In different modalities, the internal field of bristles (or the “field that has random height and / or width and / or material properties) can comprise at least 50 bristles, or at least 100 bristles, or at least 150 bristles, or at least 200 bristles, or at least 250 bristles. Preferably, each of these bristles is at least 0.5 mm thick (or at least 0.75 mm thick, or at least 0.85 mm thick, or at least 1 mm thick, depending on the modalities), and / or a height that is at least 5 mm (or at least 4 mm, or at least 6 mm, or at least 7 mm, depending on the modality). (ii) bristle height - in the case of bristles in the inner field (or “bristles that have random properties of height and / or width and / or material”) there is a variation in the height of the bristles, and bristles of different sizes may be provided heights (i.e., at least 5, or at least 8, or at least 10, or at least 12) that significantly differ from each other. In some embodiments, the average height of the bristles of the bristle field, whose heights vary substantially at random (for example, "the inner field" in the area (560)) can be on the order of magnitude of 1 cm, for example, between 7 mm and 8 mm, or between 8.5 mm and 15 mm, or between 8 mm and 14 mm. A further discussion of "bristle height" characteristics is provided below, with reference to figures 5, 7, 10-12. As will be discussed below, several other properties relating to bristle height can be provided, for example, relating to a height distribution function for the bristles of the "bristle field" (i.e., having random height properties). As clearly visible in figures 1 and 2 (and also in figure 5 that provides a height histogram), the heights within the internal field (or the “bristle field that have random properties of height and / or width and / or material ”) Are not uniform in any way, instead, there is a visible and significant“ spread ”amount of unequal heights. (iii) thickness of the bristles - in some modalities, the thickness of the bristles of the inner field (or of the bristle field that have random properties of height and / or width and / or material) and of the order of magnitude of about 1, 2 mm, for example, between 0.8 mm and 2 mm. However, the actual thickness of the bristle may depend on the material used in the bristle. A further discussion of “bristle thickness” characteristics is provided below with reference to figure 6. (iv) bristle orientation characteristics - as can be seen from the figures, the “inner field” (or “bristle field”) bristles that exhibit random properties of height and / or width and / or material ”) will typically be arranged“ straight raised ”- that is, oriented substantially normal to the local piano of the bristle retaining surface (530) and / or substantially collinear with normal to the location of the bristle surface (for example, within tolerances of 30 degrees, 20 degrees, or 10 degrees). This can occur in the case of any shape / topology of the bristle retaining surface (530), for example, flat (as shown in figures 1 and 2) or rounded, or even a fan-type brush. In some embodiments, the bristles of the “field of bristles that have random properties of height and / or width and / or material” are substantially parallel to each other (or locally parallel to each other). (v) bristle shape characteristics - as can be seen from the figures, the bristles are all substantially straight (rather than curved or arched). In addition, the bristles of the inner field (560) and / or the outer field (570) (or any bristle field that have “random height and / or width and / or material properties”) may have a substantially end rounded. Thus, for example, a substantial majority of “field” bristles are at least 60%, or 75%, or 85% or 90%. This can be useful to provide a more comfortable effect when the bristles contact the scalp of the skull. In some embodiments, the majority of bristles or a substantial majority of at least 60% or at least 70% or at least 90% of bristles in the "inner field" (or any field within the "selected area") are substantially straight. (vi) density of the bristles - as can be seen from the figures, within the central portion 5 of the brush the density of the bristles tends to be substantially constant, although not exactly constant. For modalities related to “substantially constant bristle density”, there will be no tendency towards scalable regibes within the “inner field” (or “bristle field that has random height and / or width and / or material properties”) that they are devoid of bristles or ribs where the 10 bristles are clearly “overpopulated”, compared to other ribs. (vii) fastening material / means - the bristles can be constructed of a plastic material and fixed to the brush's bristle retaining surface. An example of bristles that are "fixed" or "implanted" on the bristle retaining surface and when the bristles are glued or stapled or attached to the "brush surface" of the "15 bristle retaining surface". In another example, the bristles can be formed integrally with the brush surface. Thus, for example, the brush surface and the bristles can be made of the same material - it is possible to produce a special mold that conforms to the shape of the brush surface and the bristles - in which the geometric properties of that mold can determine the “properties long ”or 20“ thickness properties ”or“ bristle density properties ”or any other geometric properties of the brush including the bristles. This “integrally formed” brush is another example of bristles that are “fixed” or “implanted” on the bristle retaining surface. (viii) uniform local average height - a characteristic that can be clearly seen in figure 2B, where within the “internal region”, even if there is a significant variation between the heights of the individual bristles, the average local height of each bristle can vary to a lesser degree. In some modalities, in the entire region of the “bristle field that has random properties of height and / or width and / or material”, the height measured as the local average of each bristle, along the bristles that are significantly close (ie, neighboring bristles, whose height is significant, for example, at least 30%), can fluctuate to a much lesser degree than the heights of the bristles themselves. Thus, in case the most distant bristle surface (550) is softened in a neighborhood (for example, having a radius of about 7.5 mm and / or a radius equal to the average bristle height, with a tolerance of 50% , or 40%, or 30%, or 20%, or 10%) it can be seen that the height of the furthest bristle surface "softened in the neighborhood" is substantially constant. Definitions
For the sake of convenience, in the context of the present description, several terms are presented herein. Insofar as these definitions are provided, explicitly or implicitly, here or elsewhere in the present description, these definitions must be understood to be consistent with the use of the terms defined by those skilled in the relevant art. In addition, these definitions should be considered in the broadest possible sense, consistent with that use.
The modalities of the present invention are correlated with the bristle fields in which the bristles are implanted on the brush surface, so that the heights of the bristles "vary substantially at random and substantially independent of the location of the bristle on the bristle retaining surface".
For the present disclosure, when the bristle heights / lengths of a bristle field “vary in a substantially random manner and substantially independent of the location of the bristle on the bristle retaining surface”: (i) it is possible to view the bristles together as a coherent unit or “field”; (ii) there is no visually determinable pattern (that is, different from randomness) for the bristle length / height of the bristle field; and (iii) it is visually clear that the bristles of the bristle field have a “substantially random” height pattern.
It should be noted that optional objectives or additional features may be provided which do not hide or cancel the pattern of height visibly observable as 'substantially random' of the bristles of the bristle field, as described in the previous paragraph. In one example, the topology of the hairbrush may be different from the flat topology illustrated in figures 1 and 2.
In another example, there may be additional bristles, in addition to said at least 100, or at least 150, or at least 200, or at least 250 bristles from the “bristle field”, for example, located in an external field or in any other location of the bristle retaining surface. In a particular example, the additional bristles may be "short" bristles, which are substantially shorter than the inner field bristles, having "random height" properties, or "thin" bristles, or may have any other geometry. However, in the case of modalities that provide substantially random height properties, these optional objective additions or features will not hide or cancel the visibly observable substantially random height pattern of the bristles.
Thus, the bristles of the outer field of the edge (570) in figures 1 and 2 may or may not have “random height properties, however, it is clear that their presence (or the presence of any other“ additional ”bristles in any location) ) does not hide the property of random height observable in the “inner field”.
The term "substantially random" implies that the pattern of height (or pattern of width or flexibility) does not need to be exactly a mathematically random pattern, as long as these visible patterns described above are present.
When a physical and / or statistical property of a “bristle field” that exhibits random height and / or width and / or material stiffness characteristics (or any other group of bristles or bristle fields) is discussed, it is evident that this refers only to the bristle field that provides the “random height properties” and not to any additional bristles. These physical and / or statistical properties can refer to density, or height, or thickness or bristle material, or to any other property. Certain physical and / or statistical properties measured for the “bristle field” of the hairbrush shown in figures 1 and 2 are discussed in relation to several figures.
The modalities of the present invention refer to the case in which the bristles of the “bristle field” having the pattern of height and / or thickness and / or flexibility of observable material are “individually implanted”, so that they are not implanted in the form of tufts or bundles of bristles. Instead, the bristles are individually implanted on the bristle retaining surface - that is, each bristle is separately implanted on the bristle retaining surface.
Thus, as illustrated in figures 1 and 2, the bristles and / or their "closest bases / ends" are spilled together, and are not arranged "bundled", as is known in the technique of "bundles of bristles" or "tufts" bristles ”. Instead, they are implanted "individually", as illustrated in the figures.
Another important feature of the bristles that are not implanted as tufts or bundles (but instead are implanted independently), is the fact that the bristles can be parallel to each other. In some modalities, a majority or most (ie at least 70%, or at least 80% or at least 90%) of the bristles of a population are all "locally parallel" - that is, parallel to all bristles neighbors of the population - for example, all the bristles of the population of bristles closer than 1 cm or closer than 0.5 cm. Thus, even in the case of bristles implanted in a cylindrical brush, it can be said that those bristles that are not implanted in the form of tufts or bundles are locally parallel.
When a more distant bristle surface has a shape that “varies in a substantially random manner”, this means a situation in which there is no visually determinable pattern (that is, different from randomness) for the most distant surface of the bristle. Again, there may be additional bristles (which may or may not have stochastic properties of height) present, different from the “bristle field”, which form the surface of the most distant bristles (for example, bristles shorter than the “bristle field” more random or irregular or non-periodic ”from the most distant bristle surface. However, additional bristles will not cancel out the pattern of clearly observable surface shape, random or irregular, from the most distant bristle surface (550) (or a portion of it).
Some modalities refer to the case where a number of different heights (i.e., at least 5, or at least 8, or at least 10, or at least 12) that "significantly differ from each other" are provided or represented within a field of bristles. The term referred to as "significantly different" heights for the bristles and relative to the functionality of brushing the hair, as opposed to very small height variations (for example, microscopic) due to the manufacturing process. These significantly different heights are clearly visible to the user who sees the brush with the naked eye (see figures 1 and 2). In the relative examples, figures 1 and 2 (and as discussed in more detail with reference to figure 5, which represents a histogram of height of the internal field), the “variation” of at least five different heights that are substantially different from each other, and of an order of magnitude of at least a few millimeters.
When a bristle is substantially stiff, it means that even though the bristle is mostly stiff, there may still be some flexibility, for example, to make brushing a less painful experience. Thus, the expression "substantially rigid" means "rigid enough to serve its purpose, to penetrate into the hair region, in order to untangle it.
A bristle is made of sufficient thickness and is constructed of a material that will serve its purpose. In some embodiments, the bristle may have a thickness / width that is at least 0.5 mm (for example, in the case of plastic material).
With reference to figures 3A and 3B, it is observed that the “distance between the bristles” (indicated in figures 3A and 3B by DISTANCE (b /, b ) Between the bristles (bj & bz). Refers to the distance between sens centrdides at their respective “base / root / end closest to the bristles, along the surface (530) of the hairbrush.
The "location" of a bristle and the location of the center / centroid of the bristle on the brush surface (that is, at a location above the "zero height" of the brush surface 5). The “distance between the bristles” refers to the distance from center to center.
The term "bristle retaining surface" is not intended to limit a particular type of surface, but is simply designed to provide a name for the surface in which the bristles are implanted.
In the present disclosure, when the bristle widths / thicknesses of a bristle field "vary substantially at random, which is substantially independent of the location of the bristle in the bristle retaining surface", (i) it is possible to view the bristles together as a coherent unit or a “field”; and (ii) there is no visually determinable pattern (that is, different from randomness) for the length / height of the bristle, of the bristles of the bristle field; and 15 (iii) and it is then visually clear that the bristles of the bristle field have a “substantially random” height pattern.
The following is a list of several characteristics classified by "types of characteristics", describing the characteristics that can be provided by the bristles of the internal bristle field (560). Any characteristic 20 belonging to an “internal bristle field” can, in one or more modalities, refer to a bristle field having random properties of height, and / or width and / or material flexibility, disregarding whether the external field is present or not. In different embodiments, any combination of features can be provided. Discussion of Figure 4 - Counting Characteristics and Density Characteristics
Figure 4A represents a set of bristle locations for the non-limiting brush shown in Figures 1 and 2.
Figures 4A-4D illustrate certain subregions of the map in figure 4A. As can be seen from figure 4A, in the examples in figures 1-2, the internal field of bristles (560) (which in the specific case of figures 1-2 and the “selected area” of the bristles, where the random pattern of bristle can be seen) includes about 300 bristles. This is only for a specific base and a greater or lesser amount of bristles can be provided within the "selected area".
In different modalities, the number of bristles in the "selected area" of bristles where the random bristle length pattern can be observed and at least 100, at least 150, at least 200 or at least 250 bristles.
The bristles of at least 100, or at least 150, or at least 200, or at least 250 bristles can have specific properties, such as, for example: (i) the thickness / width / diameter of these bristles, which can be at least 0.5 mm, or at least 0.7 mm, or at least 0.8 mm, or at least 0.9 mm, and / or (ii) the bristle height may be at least 3 mm , or at least 5 mm, or at least 7 mm, and / or (iii) the bristle height may be a maximum of 25 mm, or a maximum of 22 mm, or a maximum of 20 mm, or not maximum of 18 mm, or a maximum of 16 mm.
In some embodiments, at least 50%, or at least 70%, or at least 80%, or at least 90%, or at least 95% of all bristles in the “selected area” have a thickness that and at least at least 0.8 mm, or at least 0.9 mm, or at least 1 mm.
Another important feature that can be seen in figure 4 is that the bristles are implanted within the internal region with a “substantially constant density”. In some embodiments, it may be preferred that the density is not exactly constant, in order to allow (or even prefer) relatively small “fluctuations” in the bristle density.
Thus, for example, there may be relatively small regions (1020) within the inner field that are devoid of bristles (or that have a very small density) and there may be relatively small regions (1024) within the inner field that have a relatively higher density. high - however, these variances are relatively small and do not eliminate the overall “substantially constant density” pattern of the bristles in the “inner field” and / or in the “field that displays a random pattern of height, and / or width, and / or material flexibility.
In some embodiments, the bristle field comprising at least 100, or at least 150, or at least 200, or at least 250 bristles is implanted over an area of the bristle retaining surface (530) of the hairbrush, the size of which is between about 20 and 100 cm2 - for example - between about 30 and about 50 cm2. As will be discussed below, different and varied bristle densities can be provided for the “inner field” bristles (or any other randomly owned field).
As indicated above, it is evident from figure 4 that, in some modalities, although some spatial fluctuation in the density of the bristles (that is, for the “inner field” bristles and / or for the bristles whose height is at least a minimum height of at least 4 mm, or at least 5 mm, or at least 6 mm, or at least 7 mm, or at least 8 mm, and / or for bristles whose thickness is at least a minimum thickness of at least 0.5 mm, or at least 0.7 mm, or at least 0.85 mm, or at least 1 mm or more) may be allowed or even desired (see regions (1024) or (1020) of figure 4), it can be desired that the overall density of the bristles of the internal field is substantially constant. Discussion of Figure 5 - Height Characteristics
The statistical properties of bristle heights for the internal field of the bristles (i.e., in the region (560)), for the specific examples of figures 1 and 2 were computed. Table 1 presents a statistical summary for this height distribution.


For the specific example of figures 1 and 2, where the internal field includes 296 bristles, the average bristle height is 11.3 mm and the standard height deviation is 2.34 mm. For the example of figures 1 and 2, the ratio between the standard deviation from the height and the mean height (i.e., ratio of SD height / mean height) is 0.21.
Figure 5 represents a “height histogram” describing the frequency of heights whose values are available within certain “binary numbers”.
An examination of figure 5 reveals that not all heights are equal, on the contrary, there is a certain “spreading”, and a variety of heights are provided. In different embodiments (as can be seen from figure 5), a number of different heights can be provided (i.e., at least 5, or at least 8, or at least 10, or at least 12, or at least 15, or at least 20 heights) that “significantly differ from each other”. The term referred to as "significantly different" heights for the bristles and relative to the functionality of brushing the hair, as opposed to very small height variations (e.g. microscopic) due to the manufacturing process. These significantly different heights are clearly visible to the user who sees the brush with the naked eye.
In different modalities, the internal field bristles have a “minimum length” or a “maximum length” (this only refers to the internal field bristles - additional non-internal field bristles can have any other length). Without any limitation with the theory, for the previous case, the shorter bristles may not be able to separate or untangle the hair. Without limiting the theory, for the latter case, the longer bristles can "interfere" with the hair untangling process, and / or increase the occurrence of pain, and / or fail to meet a positive untangle feature.
In some embodiments, at least 50%, or at least 60%, or at least 70%, or at least 80%, or at least 90%, or at least 95%, or at least 99% (any combination is possible) the bristles of the inner field (or any “random property field”) may have a minimum length that is at least 6 mm, or at least 7 mm, or at least 8 mm, or at least 9 mm, and / or may have a maximum length that is a maximum of 20 mm, or a maximum of 19 mm, or a maximum of 18 mm, or a maximum of 17 mm, or a maximum of 16 mm, or a maximum of 15 mm (any combination is possible - for example, at least 60% have a length that is at least 7 mm, and at least 80% have a length that is at most 16 mm, or any other combination).
Figure 5 describes a situation where the height variation of the bristles within the area (560) is between about 7 mm and about 16 mm. In different modalities, the height variation for the bristles within the area (560) can be between about 3.5 mm (in some modalities, between about 6 mm) and about 16 mm - for example - in some modalities, substantially all (for example, at least 80% or at least 90%) the bristles are within that height variation, that is, between any of the four height variations, that is, (a) 3.5 mm to 16 mm; (b) 3.5 mm to 18 mm; (c) 6 mm to 16 mm; and (d) 6 mm to 18 mm.
An examination of figure 5 indicates that even though the height distribution of the bristles is not exactly uniform, the height distribution may have some properties of a uniform height distribution. For example, in some modalities, a first fraction (for example, at least 5%, or at least 10%, or at least 15%, or at least 20%) of the bristle population in the inner field is constituted of “ short bristles ”, having a height in a relatively“ short ”range (height variation 1), a second fraction (for example, at least 5%, or at least 10%, or at least 15%, or at least 20% , or at least 25%) of the bristle population in the inner field is made up of “medium height bristles”, having a height in a relatively “average” range (height variation 2), and a third fraction (for example, at least least 5%, or at least 10%, or at least 15%, or at least 20%) of the bristle population in the inner field is constituted by “high bristles”, having a height in a relatively “high height” range (variation in height 3). Any combination of these percentages can be provided.
In one example, the relatively short bristles have a height between 5 mm and 9 mm from the bristles of the inner field (variation of, height ST), the bristles of “average height” have a height between 9 mm and 13 mm (variation of height Ml), and the “high bristles” have a height between 13 mm and 18 mm (variation in height Tl). This can be true for “relatively flat brushes”, for fan type brushes, the number of heights can be 10-20% higher. Thus, SI is a first version of "short"; Ml € a first version of “media”; Tl is a first “high” version; S2 6 is a second version of "short"; M2 is a second version of “media”; and T2 is a second “high” version.
In another example, the relatively short bristles have a height between 5 mm and 9.5 mm from the bristles of the inner field (height variation 1), the “medium height” bristles have a height between 9.5 mm and 12.5 mm (height variation 2), and the “high bristles” have a height between 12.5 mm and 18 mm (height variation 3).
In some embodiments, the number of bristles in the inner field (or field having “random” properties) in a variation in height of SI, and / or Ml, and / or Tl, and / or S2, and / or M2, and / or T2 (any combination can be provided) and at least 10 bristles, and / or at least 20 bristles, and / or at least 30 bristles, and / or at least 5 bristles (any combination can be provided) .
The COUNTING terminology (S7) is the bristle count of the inner field (or field having “random” properties), the height of which is in the SI height variation. This can also correlate with 51, Ml, T1, S2, M2, and / or T2.
In different modalities, any of the following proportions (any combination of proportions or any combinations of upper / lower limits) can be a minimum of 0.2, a minimum of 0.3, or a minimum of 0.4, or no minimum of 0.6, or a minimum of 0.7, a minimum of 0.8 and / or a maximum of 2, or a maximum of 1.5, or a maximum of 1.2, or a maximum of 1 , or at most 0.8, or at most 0.6, or at most 0.4, or at most 0.3, or at most 0.2L: these proportions will apply between COUNT (S7) and COUNT (A77), and / or proportion between COUNT (S2) and COUNT (A72), and / or proportion between COUNT (Tl) and COUNT (M7), and / or proportion between COUNT (T2) and COUNT (M2) . Any combination can be provided.
This relatively “uniform” bristle height distribution can be applied to the population of “significant height” bristles, to untangle hair implanted within the “selected area” (560). In different modalities, this set of bristles having bristles of “Significant unloading height” (defined as bristles having a minimum height of 2.5 mm (or 3 mm, or 3.5 mm, or 4 mm, or 4.5 mm, or 5 mm) and a maximum height of 17, 5 mm (or 21 mm, or 20 mm, or 25 19 nun, or 18 mm, or 17 mm - where any combination of these numbers is possible) implanted within the selected area, presents the minimum count, as discussed in the previous section, or ie at least 100 bristles, at least 150, at least 200 or at least 250 bristles, and / or a minimum thickness of at least 0.5 mm, at least 0.7 mm, at least 0.8 mm or at least 0.9 mm.
In different modalities, the proportion of standard deviation of average height / height of the bristles of the internal field (or any other field having “random properties” implanted in any selected area is at least 0.05, or at least 0.075, or a minimum of 0.1, a minimum of 0.125, or a minimum of 0.15, or a minimum of 0.2, and / or a maximum of 0.6, or a maximum of 0.5, or a maximum 0.4, or a maximum of 0.3, or a maximum of 0.25. Again, this indicates a “height spread”.
In different modalities, the average height of the bristles of the internal field (that is, for example, the bristles of a “significant height”, which vary from about 2.5 mm to about 17.5 mm) and at least 6 mm, or a minimum of 7 mm, or a minimum of 8 mm, or a minimum of 8.5 mm, and / or a maximum of 16 mm, or a maximum of 15 mm, or a maximum of 14 mm, or not maximum of 13 mm, or a maximum of 12 mm. Any combination of these values can be used in any modality.
In different modalities for the bristles of the internal field, the standard deviation of the height of the bristle population of the internal field can be at least 1 mm, or at least 1.5 mm, or at least 2 mm, and / or at least maximum of 5 mm, or a maximum of 4 mm, or a maximum of 3 mm.
Obviously, any combinations of minimum standard height deviation and any combinations of maximum standard height deviation and / or mean height can be provided.
In some embodiments, the field of bristles is made substantially entirely of bristles (i.e., at least 70%, or at least 80%, or at least 90%, or at least 95%, or at least 99%) in a given “Selected area” (for example, the region (560) in figures 2 and 3), whose height has any height characteristic or combination of characteristics disclosed herein, and / or whose width has any characteristic of width or combination of characteristics disclosed herein . Bristle Width Characteristics - A Discussion of Figure 6
As indicated above, bristles that have a width that is at least 0.5 mm, for example, this value can be the limit for “individual” non-bundled bristles (ie, for most materials from which hair brushes are typically constructed, for example, of plastic material), in which the bristles that are different from the shape of tufts or bundles (that is, individually implanted) are thick enough to penetrate significantly within the region and untangle the hair.
In different modalities, the internal field bristles have a "minimum thickness" or a "maximum thickness extension" (this only refers to the internal field bristles - additional external field bristles can have any other extension).
In some embodiments, at least 50%, or at least 60%, or at least 70%, or at least 80%, or at least 90%, or at least 95%, or at least 99% (any combination is possible) the bristles of the inner field (or any “random property field”) may have an extension of thickness that is at least 0.5 mm, or at least 0.7 mm, or at least 0.85 mm, or at least 0.9 mm, or at least 1 mm, or at least 1.1 mm, or at least 1.2 mm, and / or may have a maximum thickness that is at most 3 mm, or a maximum of 2.5 mm, or a maximum of 2 mm, or a maximum of 1.8 mm, or a maximum of 1.5 mm, or a maximum of 1.3 mm (any combination is possible).
In addition, the modalities of the present invention refer to hairbrushes where a variety of widths (or material flexibilities) are provided, "n" of some modalities, instead of all bristles having the same width (or the same material flexibility), it is possible to provide a variety of bristle widths (e.g., at least 2, or at least 3, or at least 4, or at least 5) that significantly differ from each other.
Figure 6 illustrates the bristle width (Y axis) as a function of the bristle height (X axis), for the non-limiting case of Figures 1 and 2 (that is, for the internal field in the region (560) or for any another bristle field that provides random properties of height, width or flexibility of materials. As can be seen from figure 6: (i) there are multiple widths that significantly differ from each other - in the example in figure 6, some bristles in the internal field have a width which is about 1, some bristles in the inner field have a width that is about 1.2, some bristles in the inner field have a width that is about 1.4, and some bristles in the inner field have a width width which is about 1.6; (ii) there is a clear correlation between the height of the bristle and the thickness of the bristle - that is, the tallest bristles tend to be thicker.
Alternatively, or in addition, the higher bristles can be constructed from a less flexible material.
It is observed that, in general, the higher bristles tend to be more flexible than the shorter bristles. Without wishing to be bound by any limitation by theory, if the internal field (or any “field of random properties”) provides relatively high bristles and relatively short bristles, it is possible that the relatively higher bristles will exhibit a much greater degree of flexibility than than the relatively short bristles. In order to mitigate this effect (or for any other reason), it may be useful to configure the hairbrush so that the higher bristles are “reinforced” with a greater thickness (alternatively, or additionally, made of a less flexible material ), while the shorter bristles are built with less thickness or a more flexible material, to counterbalance the tendency to become “too rigid”.
This may be possible to provide a situation in which the bristle stiffness varies less than would otherwise be observed, and / or which can still be substantially constant.
The person skilled in the art will know how to observe the difference between, on the one hand, "material stiffness" or "material flexibility", and on the other hand, between "bristle stiffness" or "bristle flexibility" (ie, this could at least determined by combining material flexibility / stiffness, bristle height and bristle thickness).
The modalities of the present invention refer to situations in which the bristles are implanted on the bristle retaining surface, so that the height of the bristles can vary in a substantially random manner, and these heights are substantially independent of the location of the bristle on said retaining surface. of bristles. In the modalities in which this applies, there is a clear correlation between the height of the bristle and the thickness of the bristle (for example, where the higher bristles are thicker, as shown in figure 6), then it is evident that the thickness of the bristle bristle (or, alternatively, the flexibility of the material) can also vary in a substantially random manner, which is substantially independent of the location of the bristle on the bristle retaining surface.
In different modalities, one or more of the following characteristics can be provided for the “inner field” of bristles (or any bristle field that has any “random properties”): (i) the average thickness of the bristle can be at least 0 , 85 mm, or at least 1 mm, or at least 1.15 mm, or at least 1.25 mm; (ii) the average thickness of the bristle can be a maximum of 2.5 mm, or a maximum of 2 mm, or a maximum of 1.75 mm, or a maximum of 1.5 mm, or a maximum of 1.4 mm; (iii) a variety of thicknesses is provided with standard thickness deviation, where the standard bristle thickness deviation is at least 3%, or at least 5%, or at least 7%, or at least 10 %, or at least 12%, or at least 15%, in relation to the average thickness of the bristle; (iv) in some embodiments, the standard deviation of the thickness of the bristle is at most 50%, or at most 40%, or at most 30%, or at most 20% of the mean thickness of the bristle; (v) there is a “positive correlation” between the thickness of the bristle and the heights of the bristles, so that, on average, the higher bristles are thicker, and the shorter bristles are thinner (see figure 6, where the X axis represents the height of the bristles in mm and the Y axis represents the thickness of the bristle in mm, and it is still clear from figure 6 that the higher bristles tend to be thicker, this can be useful to provide a mixture of different bristle flexibilities; (vi) in some modalities related to this “positive correlation” (see figure 6), the highest 20% of the population's bristles have an average height indicated by Hl, & an average thickness indicated by Tl. Shorter 20% of the population's bristles have an average height indicated H2 and an average thickness indicated by T2; in this example, a proportion between T1 and T2 can be at least 1.1 or at least 1.2, or at least 1.3, or at least 1.4, or even at least 1.5; (vii) in an example (that is, both in the context of height in general OR in the context of the “positive correlation between height and width”), the proportion between Hl and H2 can be at least 1.1 or at least 1.3, or of at least 1.4, or at least 1.5, and / or at most 3, or at most 2.5, or at most 2.5, or at most 2, or at most 1.75, or a maximum of 1.5; (viii) some or most of all the bristles of the bristle population of the inner field (560) may tend to be somewhat or substantially rigid.
In some embodiments, the field of bristles is made substantially entirely of bristles (i.e., at least 70%, or at least 80%, or at least 90%, or at least 95%, or at least 99%) in a given “Selected area” (for example, the region (560) in figures 2 and 3), whose height has any height characteristic or combination of characteristics disclosed herein, and / or whose width has any characteristic of width or combination of characteristics disclosed herein .
In some embodiments, for a majority (or a substantial majority of bristles, for example, that consists of at least 60%, or at least 70%, or at least 80%, or at least 90%, or at least 95% ), a ratio between a bristle length and a bristle width is at least 2.5, or at least 3, or at least 5, or at least 5, and / or at most 30, or at most 25, or a maximum of 20, or a maximum of 10. Closest Bristle Histogram - Discussion of Figure 7
For a field of N bristles (N being a positive integer) implanted on a hairbrush surface, the bristles of the field can be indicated by (£> ;, 10 b , ... bN). For the "k-esima" bristle (bit), the bristle field provides a set of numbers Nl {DISTANCE (b /, bk), DISTANCE (b2, ^ ... DISTANCE ^ z, bk), DISTANCE (bt + y , 6 *), ... DISTANCE ^ bk)} - where the minimum value of this number Nl of this set of distances and the distance between the bristle (bk) and the "closest distance" from the other bristle. Therefore, each bristle (bk) (k being a positive integer between 1 and 15 N) € associated with a respective “closest bristle distance”.
These numbers were computed in the “inner field” of the bristles for the example shown in figures 1 and 2. A histogram of these numbers is shown in figure 7, whose statistical parameters are shown below:


Therefore, for the bristles of the “inner field” and / or a field that has random properties, the median value of the furthest bristle is 3.89 and the standard deviation is 0.6. The ratio between the standard deviation and the mean is 0.15. In different modalities, this proportion can be at least 0.05, or at least 0.075, or at least 0.1, or at most 0.5, or at most 0.4, or at most 0 , 3, or a maximum of 0.25, or a maximum of 0.2.
In different modalities, the average value of the bristle closest to the bristles of the internal field can be at least 2 mm, and / or at least 2.5 mm, and / or at least 3 mm, and / or at most 7 mm, and / or a maximum of 6 mm, and / or a maximum of 5 mm, and / or a maximum of 4 mm.
In different modalities, the average value of the bristle closest to the internal field bristles (where the average height of the internal field bristles and HAVG) can be at least 0.15 * HM, and / or at least 0.2 * HAVG, and / or at least 0.25 * HAVG, and / or at least 0.3 * HAVG, and / or at most 0.7 * HAVG, at most 0.6 * HAVG, and / or maximum 0.5 * HAVG, and / or maximum 0.4 * HAVG, and / or maximum 0.3 * HAVG-
In different modalities, each bristle of at least 50%, or at least 60%, or at least 70%, or at least 90%, or at least 95% of the “inner field” bristles (or any other field that has random bristle properties) may have respective values of "closest bristles", which refer to the closest bristles that are also in the "inner field" (or any other bristle field that has random properties), which are at least 2 mm, and / or at least 2.5 mm, and / or at least 3 mm, and / or at most 7 mm, and / or at most 6 mm, and / or at least maximum 5 mm, and / or a maximum of 4 mm.
In different modalities, each bristle of at least 50%, or at least 60%, or at least 70%, or at least 90%, or at least 95% of the “inner field” bristles (or any other field that has random bristle properties) may have respective values of "closest bristles", which refer to the closest bristles that are also found in the "inner field" (or any other bristle field that has random properties), which are of the internal field (where the average height of the bristles of the internal field and HAVG), can be at least 0.15 * HAVG, and / or at least 0.2 * HAVG, and / or at least 0.25 * HAVG, and / or at least 0.3 * HAVG, and / or at most 0.7 * HAVG, and / or at most 0.6 * HAVG, and / or at most 0.5 * HAVG , and / or a maximum of 0.4 * HAVG, and / or a maximum of 0.3 * HAVG-
In some modalities: (i) each bristle “h” of the bristle field (ie, internal field or “field of random properties”) is associated with a respective closest bristle distance, which indicates the respective closest distance between the bristle “6” and any other bristle in the same bristle field; (ii) a ratio between a standard deviation of the bristle distances closest to the P bristle population and an average of the bristle distances closest to the P 6 population at the most 0.25 or at the most 0.2 (in the example of figure 8A and 0.15).
An important feature of figure 8 is that a fraction of most internal field bristles has a "closest distance value" which is approximately a peak value or "closest representative distance" (i.e., within a tolerance 5%, or 10% or 15%) - this peak value being defined by the frequency of the “peak value” or “next” numbers within the tolerance. However, an additional subset of field bristles have “deviation values”, which deviate from the representative value (RCDV) of at least 5%, or at least 10%, or at least 15%, or at least 20 %, or at least 1.2 times, or at least 1.4 times, or at least 1.5 times, or at least 1 time, or at least 2 times, of the "tolerance" for ( RCDV). Grid Value - A Discussion of Figure 8
In some embodiments, it is possible to describe fluctuations in bristle density within region (560) of the “inner field” (or any other region that “hosts” a field with any random properties - for example, height, or thickness, or material flexibility) as follows: (i) first, a square grid of 1 mm by 1 mm is placed in the “host region” (560) (see figure 8A) - the points of intersection at which perpendicular lines intersect between themselves are the “grid points”.
It is possible for each grid point to measure the number of bristles in the inner field (or any field with random properties) that are “close” to the grid point (that is, less than a “boundary distance”) - for example, within 1 cm or within 7.5 cm, or within 6.5 cm and / or within a distance that is HAVG (again: the average height of the bristles in the field of random properties and HAVG), on within 0.9 * HAVG, or within 0.8 * HAVG, OR within 0.7 * HAVG, OR within 0.6 * HAVG, OR within 0.5 * HAVG, using bristle to bristle distance, defined as shown in figure 4. These distances are referred to as possible “limit distances”.
For the case of figures 1 and 2, a limit distance of 7.5 mm was used and the number of grid points within the “contention region” or “host region” of the internal field was 3490 - this indicates an area of about 35 cm2. Each grid point provided was associated with a different respective “proximal bristle” value, which describes how many bristles of the inner field (or any field with random properties) were respectively less than the “boundary distance” from the provided grid point. Thus, for the example of figures 1 and 2, which had 3490 grid points, 3490 values were computed for the “number of proximal bristles”. Statistical data were computed based on these 3490 values.
The average grid point had 10.13 bristles, whose distance from the grid point was less than the "boundary" distance (see previous paragraphs for possible definitions of the "boundary distance" - for example, in figures 1 and 2, the distance limit was 7.5 mm).
While the “average value” between grid points was 10.13 bristles, the standard deviation was only 1.31.
The relatively small proportion of standard deviation (SD) / average is 0.13 and another indication of "substantially constant density" of the internal field of the bristles. In different modalities, this value can be less than 0.3, less than 0.25 or less than 0.2, or less than 0.15, and / or greater than 0.03, or greater than 0.05 or greater than 0.07, or greater than 0.1.
Also, for the limit value of 7.5 mm, the average number of bristles was 10.13, - this indicates that the internal field (or any other field of random bristle properties) is implanted with a density of about 10 , 13 / (3.14 * 0.75 cm * 0.75 cm) = 5.7 bristles / cm2.
In different modalities, the density (or substantially constant density) of the bristles of the inner field (or any other field of bristles of random properties) can be at least 2 bristles / cm2, or at least 3 bristles / cm2, or at least 4 bristles / cm2, or at least 5 bristles / cm2, and / or a maximum of 30 bristles / cm2, or a maximum of 20 bristles / cm2, or a maximum of 15 bristles / cm2, or a maximum of 12 bristles / cm2, or a maximum of 10 bristles / cm2, or a maximum of 8 bristles / cm2, or a maximum of 7 bristles / cm "- and where any combination is possible. These inner field bristles can provide height properties random and / or random thickness, and / or random material flexibility ern some modalities, most (ie at least 50%, or at least 60%, or at least 70%, or at least 80% , or at least 90%) of these bristles can all have a thickness of at least 0.5 mm, or at least 0.7 mm, or at least 0.85 mm, and / or a bristle height / length of to least 5 mm, or at least 6 mm, or at least 7 mm, or at least 8 mm.
In some embodiments, the internal bristle field or “random properties” field, comprising at least 100, or at least 50, or at least 200, or at least 250 bristles, is implanted over an area of the bristle retaining surface (530) of the hairbrush, whose size, for example, is between about 20 and 100 cm2, or between about 30 and 50 cm2. As will be discussed below, different bristle densities and variations can be provided for the “inner field” bristles (or any other field of random properties).
In different modalities, one or more (that is, any combination) of the following characteristics can be provided correlated to the locations of the bristles: (i) the bristles of the inner field are implanted in the bristle retaining surface (530) with a density that varies between approximately 4 bristles / cm2 and 12 bristles / cm2 - for example, about 7 bristles / cm2, within a tolerance of 50%. In some embodiments, this density can be at least 2 bristles / cm, or at least 3 bristles / cm2, or at least 4 bristles / cm2. In some embodiments, this density can be a maximum of 20 bristles / cm2, or a maximum of 12 bristles / cm2, or a maximum of 10 bristles / cm2, or a maximum of 8 bristles / cm2; (ii) the internal field of the bristles and implanted in such a way that most or even a significant majority of the bristles (for example, at least 80%, or at least 90%, or at least 99%) are available in the form of a constant lattice, however, a minority of the bristles (for example, at least 2%, or 5% or 10%) are available in positions far from the positions defined by the lattice. In one model, the internal field of bristles includes about 300 bristles, which define about 1080 distances from “neighboring bristle”, where the neighboring bristles are less than 6.5 mm apart - in this model, approximately 40% of these distances were exactly a first value, for example, 6 mm (within a low percentage tolerance, or even 2% or 1%), and approximately 40% of these distances were exactly a second value, which differs from the first value of at least 1 or 2 mm, or at least 10%, 20% or 30% - for example, 4.25 mm, however, the other distances showed different values; (iii) each given bristle can be associated with a "closest bristle distance" - this refers to the bristle closest to the hairbrush, from the bristle provided. In some embodiments, at least a majority, or at least a substantial majority of at least 75% of the bristles have a distance of "closest neighbor bristle", which is at least 1 mm, or at least 1.5 mm , or at least 2 mm, or at least 2.5 mm. Without any limitation, this can be correlated to the characteristic in which the bristles are "independently implanted" - that is, in contrast to tufts or "bundles of bristles", where the roots of the bristles are arranged in "bunches". Thus, in the example of figure 7, most of the bristles have a “distance of the closest bristle”, of about 4.5 mm; (iv) each implanted bristle can be associated with a “bristle of the closest neighborhood having a height distance of at least 5 mm”, this distance refers to the closest bristle (that is, between bristles whose height is at least 5 mm) arranged on the hairbrush, from the bristle provided. In some embodiments, at least a majority, or at least a substantial majority of at least 75% of the bristles have a "closest neighbor bristle with a height of at least 5 mm", a distance of at least 1 mm, or at least 1.5 mm, or at least 2 mm, or at least 2.5 mm; (v) in some embodiments, a greater part of the bristles or a substantial majority of at least 60%, or at least 70%, or at least 80%, or at least 90% of the “inner field” bristles (or any “Field of random properties”) has a distance of “closest neighborhood bristle” that is available within 50%, 40% or 30% of an “average closest neighborhood bristle value” - in the example in figure 7, most of the bristles have a neighborhood bristle value that is closer than about 4.5 mm. In some modalities, at least a significant minority (for example, at least 2%, or at least 5%, or at least 10%) has a “closer bristle distance” that deviates significantly (for example, from at least 5%, or at least 10%, or at least 15%, or at least 20%) of the average and / or the most common "nearest neighborhood distance". Discussion of Figure 9
It should be noted that the example shown by the figures refers to the specific case of a brush with a substantially flat bristle surface, in which the bristles are implanted. In some embodiments, the surface of the bristle may have a curvature. In one example, there is a visible curvature, but the bristle surface can still be mostly flat. In another example (such as, correlating the so-called “fan brushes” or “roller brushes” - see figure 9 - or any other type of brush), the bristle surface may have a rounded shape, or a substantially cylindrical shape , in which the heights of the bristles are mainly random (or exhibit any other characteristic of height disclosed herein) along the cylindrical or rounded surface of the hairbrush.
In some embodiments, the brush may take any shape, including, but not limited to, a shape of a pet brush (NOT SHOWN) - for example, having plastic bristles. Discussion of Figures 10A-10E
Figure 10A represents a plot of locations (units are in mm) of the bristles for the examples in figures 1 and 2. As is evident from figure 10A, despite the presence of relatively small regions with “more dispersed” bristle densities (1020 ) and “more concentrated” bristle densities, taken as a whole, it is evident that the bristle density in the “host region” (in this case, the region (560)) that hosts the internal field is substantially constant.
The average bristle length / height for the “internal bristle field” (or any other field that has random properties) is defined as HAVG or ALTURA _AVG (both forms are equivalent, the notation is a little different). The standard deviation of the bristle length / height is indicated by ALTURA_SD. It is possible to define four subsets of heights for the bristles of the bristle field (for example, in region (560)): (i) a “quite high subset” (VTB) of bristles, whose height exceeds a sum of ALTURA_AVG andALTURA_SD- , (ii) a 5 "high subset" (IB) of bristles, whose height exceeds ALTURA _AVG, but, and less than the sum of ALTURA_AVG and ALTURASD-, (iii) a "low subset" (SB) of bristles, whose height and less than HEIGHT J ^ VG, but, it exceeds a sum of HEIGHT AVG and ALTURA_SD ', (iv) a “very low subset” (VSB) of bristles, whose height is less than a difference between ALTURA_A VG and ALTURA_SD.
The first and last subsets are referred to as “subsets of irregular heights”, since they refer to heights with relatively “large” deviations from the average height.
In some modalities, the cardinality of each subset is “significant” - for example, at least 7%, or at least 10%, or at least 12%, 15 or at least 15% of the total cardinality of the “bristle field”.
It is possible to observe the following contrast when the “implantation of bristles” between the “field as a whole” and the various sub-populations: the bristles of the field of bristles as a whole are implanted with a substantially constant density within an area “ selected host (5A) (560) of the bristle retaining surface 20; the bristles of any one, or two, or three, or four (i.e., any combination) of the aforementioned subsets (VTB, TB, SB, VSB) are individually implanted on the bristle retaining surface, so that a contrast occurs between the implantation of the bristle field as a whole and the implantation of at least a subset of irregular heights (HOS), so that the bristles of the subset of irregular heights (HOS) are spread in irregular and non-periodic locations within the area selected (SA)
These contrasts can be attributed to the fact that the height distribution of the bristles, in some cases, resembles a random or semi-random height distribution. Discussion of Figure 11
For the “internal field of bristles” (or any other “field of random properties”) it is possible to associate each bristle of the “internal field” with a respective group of “proximal bristles”, whose distance from “each bristle” and lower at a maximum limit distance - for example, within 1 cm or within 7.5 mm, or within 6.5 mm, and / or within a distance that is HAVG (again: the average height of the bristles of the “field of random properties ”and HAVG), OR within a distance of 0.9 * HAVG, OR 0.8 * HAVG, OR 0.7 * HAVG, or 0.6 * HAVG, OR 0.5 * HAVG, and / or optionally greater than a minimum distance (i.e., at least 1 mm, and / or at least 1.5 mm or at least 2 mm).
The height of each bristle can be measured with the “closest bristles” (that is, whose distance is less than the maximum limit and, optionally, exceeds the minimum limit). For the value of 7.5 mm (and not the minimum), this was an indicated value, and observed that the “local average height” tends to be approximately the same as the average height of the “internal field” (and / or any field of random properties) of bristles, maintaining the standard deviation.
The resulting histogram is illustrated in figure 11, whose obtained statistical properties are shown in the table below.


In contrast to the “global field”, where the standard deviation from height was approximately 0.21 (that is, proportion of SD / average height = 0.21), in the case “measured location”, the standard deviation from height was about 0.06. This is evident as shown in the “tighter” peak in figure 11, when compared to figure 5. In different modalities: (i) the proportion between SD / media for the “measured local case” of the internal field bristles and / or random properties field (see figure 11) for: (ii) the ratio between SD / media for the “original case” and a maximum of 0.5, or a maximum of 0.4, or a maximum of 0.3 , or a maximum of 0.2.
Therefore (LA is an abbreviation for “local media”), in some modalities, for the radius R-7.5 mm, for the internal field: (i) the average height of all bristles (6) of the population (P) and substantially equal to the local average height LA (b, 7.5) [radius = 7.5 mm] of all bristles (b) of the inner field (i.e., all bristles within the region shown - for example, the region (560); (ii) the standard deviation of the average local height LA (b, 7.5) is significantly less than the standard deviation of the height distribution of all bristles (b) of the population (P) (for example, a proportion between the standard deviation of the local average height LA (b, 7.5) and the standard deviation of the height distribution of all bristles (b) of the population (P) can be a maximum of 0.6, or a maximum of 0 , 5, or a maximum of 0.4).
This indicates that the height distribution is relatively homogeneous throughout the internal region - this is an indication of a random or semi-random height distribution and relatively "high" entropy. Discussion of Figures 12A-12D
For each displayed bristle of the population, the respective closest distance between the bristle supplied from the population and another bristle of the population (that is, the "other" bristle closest to the population) and the "closest bristle distance within the population". In figure 7, it is evident that the most common value of "closest distance" (that is, for the specific example of figures 1 and 2), is about 4.5 mm.
For each bristle supplied from any sub-population, the respective distance between the bristle supplied from the population and another bristle from the sub-population (that is, the “other” bristle closest to the sub-population) and the “closest bristle distance” within the under-population ”.
Because each bristle of a population (or sub-population) can be assigned a respective “closest bristle distance”, it is possible to compute statistical properties across a population or sub-population. In Figures 12A-12D, the “average value of the nearest distances” is computed and presented (ie, for a population or sub-population), as well as the “standard deviation from closer distances” (ie, for a population or underpopulation).
A metric value for any population or sub-population is the SD_AVG (CERDA_MAIS PROXIMA) metric value, defined by the standard deviation quotient divided by the average. Smaller values of SD_AVG are indicative of bristles (of a population or sub-population) that are relatively evenly distributed over the brush's retaining surface. Higher values of> S'D_AVG 'are indicative of bristles (of a population or sub-population) that are relatively relatively evenly distributed over the brush's retaining surface.
In some modalities, the value of SD_AVG (CERDA_MAIS PROXIMA) for the total population is less than 0.3, or less than 0.25, or less than 0.2, or less than 0.175.
In the example of figures 12A-12D: (i) for the total population, SD_AVG & equals 0.15; (ii) for the sub-population of figure 10B, (see figure 12A), SD_AVG is equal to 0.37; (iii) for the sub-population of figure 10C, (see figure 12B), SD_AVG & equal to 0.28; (iv) for the sub-population of figure 10D, (see figure 12C), SD_AVG is equal to 0.34; (v) for the sub-population of figure 10E, (see figure 12D), SD_AVG & is equal to 0.35.
In some embodiments, the proportion: (i) of the SD_AVG parameter (CERDAJWA1S PROXIMA) to any one, or two, or three or all four of the sub-populations (that is, at least one, or at least two, or at least minus three, or all four sub-populations in the group consisting of “very short sub-population”, “short sub-population”, “very high sub-population”, and “high sub-population”) for: (ii ) the SD_AVG parameter (CERDA_MAIS PROXIMA) for the total population, is at least 1.3, or at least 1.5, or at least 1.7, or at least 2. This indicates that the sub- populations, when this proportion (s) exceeds one of these values, they are distributed in a “less regular” manner within the selected area of a given area (for example, the area of the “inner field”), differently of the total population.
Another parameter that can be studied, for each bristle supplied from a population or sub-population, is the respective number of bristles within a certain distance (for example, 1.2 cm, or 1 cm, or 7.5 mm or 6 , 5 mm) of the bristle provided that is within the "selected area", and the elements of population and sub-population. This is possible to compute the statistics of this metric value in the population or sub-population (with figure 9 as a parameter) and to determine the means and standard deviations. An Additional Discussion Correlated to Figure 8
A metrical parameter correlated to figure 8, which describes how “regularly” the bristles of a population or sub-populations are distributed in a selected area, for each bristle supplied from a population or sub-population, and SD_AVG (CERDAS_LOCAIS, 7, 5mm) or SD_AVG (CERDA_MAIS PROXIMA) 6.5mm) or SD_AVG {CERDA_MAIS PROXIMA) ,! cm), etc.
In some modalities (that is, correlated to the parameters in figure 9), SD_AVG (CERDASJLOCAIS, 7.5mm) for the total population is less than 0.3, or less than 0.25, or less than 0.2, or less than 0.175, or less than 0.15.
In some modalities, the proportion: (i) of the SD_AVG (CERDAS_LOCAIS, 7.5mm) or SD_AVG (CERDA_LOCAIS, 65mm) or SD_AVG (CERDAS_LOCAIS, I mm) parameter to any one, or two, or three or all four of the sub-populations (that is, at least one, or at least two, or at least three, or all four sub-populations in the group consisting of “rather short sub-population”, “short sub-population”, “sub -quite high population ", and" high sub-population ") for: (ii) the parameter of SD_AVG (CERDAS_LOCAIS, 7.5 mm) or SD_AVG (CERDA_LOCAIS, 65 mm) or SD_AVG (CERDAS_LOCAIS, 1 mm) for the total population , and at least 1.5, or at least 1.75, or at least 2, or at least 2.5, or at least 3, or at least 3.5. When that proportion (bes) exceeds one of these values, it may be indicative that subpopulations are distributed in a “less regular” manner within the selected area of a given area (for example, the “inland field” area), unlike the total population.
In some modalities, the pattern of "more regular distribution" for the total population, less regular distribution for sub-populations, may prevail only for the "inner field" (560), in some modalities, there is a much smaller height variation in the external field (570).
In some embodiments, the bristles of the inner field (560) or the outer field (570) are substantially parallel to each other. In some embodiments, the bristles of the inner field (560) and / or the outer field (570) are substantially straight and / or implanted in a manner substantially normal to the local piano of the bristle retaining surface.
It should be noted that in some modalities: (i) the height of the bristles can be substantially random and substantially independent of the location of the bristle (that is, for the bristles within a certain area, for example, the internal field); and (ii) there may be a positive correlation between the thickness of the bristle and the height of the bristle. Thus, some embodiments of the present invention refer to the situation in which the thickness of the bristles is substantially random and substantially independent of the location of the bristle. This, in some embodiments, may be another way for the hairbrush to provide one or more "entropy features" or "randomness features". Discussion of Figure 13
Figure 13 illustrates locations of the “external field” of bristles - for example, located around and / or confirmed and a relatively thin or small region around most of the “internal field” parameter.
In some modalities, an "external bristle field" is also provided, presenting the following characteristics: (i) the external bristle field (570) and also implanted with a substantially constant density of bristles per area, in the perimeter of the internal field of bristles. bristles (560), substantially (but not necessarily completely) surrounding the internal bristle field on the bristle retaining surface (530) - in one example, this density is substantially the same or may be greater than the bristle density of the field internal (560); (ii) the average height of the bristles of the “outer field” of bristles (570) and, for example, a maximum of 50%, or a maximum of 40%, or a maximum of 30%, or a maximum of 20%, or at most 15% of the average height of the bristles of the inner bristle field (560); (111) the “external bristle field” (570) may omit the “substantially random height” characteristic of the internal bristle field; (iv) the number of bristles in the external bristle field is at least 15%, or 20%, or 30% of the number of bristles in the internal bristle field; (v) in some modalities, less (or much less) variation of bristle thickness in the external field of bristles - thus, the average thickness can be about 1 mm, but the standard deviation can be at most 0, 1, or a maximum of 0.05 mm (or even less) - for example, a maximum of 30% of the standard deviation of the bristle thickness of the internal field; (vi) in some embodiments, the external field of bristles is substantially surrounded by a region that is substantially free of bristles - see, for example, figure 1; (vii) in some modalities, the majority of bristles or (substantially a majority of at least 60%, or at least 70%, or at least 80%, or at least 90%) of “external field” bristles ( or any field within the selected area) is substantially straight. "In vitro" technique for measuring the strength of the hairbrush
The present inventor is currently conducting experiments, in which, a hair from a wig is untangled using: (i) a hairbrush according to some modalities (for example, see figures 1 and 2); and (ii) a conventional hairbrush as a “control”. According to these experiments, it is possible to measure the force imposed on the hair of the wig using the hair unstuck brush. There are preliminary indications that when untangling the hair from the wig using both brushes, the force imposed by the new brush provided by the modalities of the Invention and less than the force imposed by the conventional brush. Results of Clinical Experiments
The present inventor implemented a hairbrush model built and tested against the state-of-the-art “common model” hairbrush model (“model B”) for 25 women with long hair (see figure 14).
The brush (B) and the state of the art brush; the brush (A) was constructed in accordance with some of the modalities of the present invention.
As is evident from figure 14, the “Invention” brush performed a consistently little better hair separation (ie, less than 50%), with a significantly faster “brushing time” (1 minute 33 seconds versus 45 seconds) ). The brushing time was the amount of time it took the person to untangle the hair from the head - a longer hair brushing time would typically be due to a greater degree of pain felt at the untangling, and when the untangling was less painful, faster brushing was possible. Blocking Bristles / Substantially Colinear Bristles
Figure 15 is now referenced, which illustrates 3 bristles - Bl, B2 and B3. Bl is closer to B2 than B3. Two vectors are illustrated in figure 5 - B1-B2 and B1-B3. The angle between B1-B2 and B1-B3 6 is 6 (theta). In some modalities, when 6- 0, within a tolerance that is at most 30 degrees, or at most 25 degrees, or at most 20 degrees, or at most 15 degrees, or at most 10 degrees, or at a maximum of 5 degrees, then bristles B1-B2-B3 are considered “substantially collinear”. This tolerance is referred to as "substantially collinear bristle tolerance". While any tolerance can be used in any modality, unless otherwise stated, the "substantially collinear bristle tolerance" standard is 20 degrees.
In some modalities, if B2 is closer to Bl than B3, and if bristles B1-B2-B3 are considered to be substantially collinear, then B3 is considered to be "blocked" by B2 (in relation to bristle Bl). In some embodiments, B2 may have to satisfy additional requirements, in addition to the “substantially collinear requirement”, in order to block the B3 bristle - for example, B2 can have a height and / or a width in any range of variation (for example , any variation disclosed here), or B2 may present a minimum distance from bristle Bl, in order to "block" the bristleB3. Mapping of Bristles to Letters, according to the Height, Thickness or Flexibility of Material
In some modalities, it is possible to classify each bristle of any set of bristles (for example, of the “inner field” or of any set of bristles that exhibit random properties of height, or thickness or flexibility of material) in a different classification of height. or different thickness classification, according to "classification schemes".
According to a first mapping scheme, it is possible to compare the height of the bristles with each other, and divide the bristles into four height categories - for example, in “height quartiles”.
As defined by Wikipedia on “quartiles”, “in descriptive statistics, one quartile and one of four equal groups, representing a quarter of the distributed sample population. That and a kind of "quantile". It should be noted that when more than one bristle has exactly the same length / height (or when the total number of bristles in the bristle set is not divisible by four, the four groups of “quartiles” will not necessarily be exactly the same size , but about the same size.
Therefore, according to the “FIRST MAPPING SCHEME”, the bristles are divided into four height classes - upper quartile (associated with “the letter A”), upper intermediate quartile (associated with “the letter B”), intermediate quartile lower (associated with “the letter C”), and lower quartile (associated with “the letter D”). Each bristle is respectively mapped to the letter A, or to the letter B, or to the letter C, or to the letter D. For the non-limiting example of the “inner field” of the hairbrush shown in figures 1 and 2, whose histogram of height distribution is shown in figure 5, the bristles whose height exceeds 13.3 mm, can be considered as bristles of “height of the upper quartile” or bristles “A”; bristles whose height is less than or equal to 13.3 mm, and whose height exceeds 11.3 mm can be considered as bristles of “height of the upper intermediate quartile” or bristles “B”; bristles whose height is less than or equal to 11.3 mm, and whose height exceeds 9.3 mm can be considered as bristles of “lower intermediate quartile height” or “C” bristles; and bristles whose height is less than or equal to 9.3 mm can be considered as “lower quartile height” or “D” bristles.
According to another mapping scheme (ie, a “SECOND MAPPING SCHEME”), the bristles are similarly divided into four thickness / width classes - for example, “upper quartile thickness”, “upper intermediate quartile thickness”, “Lower intermediate quartile thickness” and “lower quartile thickness.” For the hairbrush shown in figures 1 and 2, whose thickness properties are illustrated in figure 6, the bristles with a thickness of about 1.6 mm are the “bristles of thickness A”, the bristles with a thickness of about 1.42 mm are the “bristles of thickness B”, the bristles with a thickness of about 1.2 mm are the “bristles of thickness C”, and the bristles with a thickness of about 1 mm are the “bristles of thickness D”,
It can be seen that the quartiles are just an example of a quanil. Quartiles (or quaniles of 4) are associated with a "4 letter set alphabet" - (A, B, C, D). The quaniles of 3 are associated with a "3 letter set alphabet" - (A, B, C). The quaniles of 5 are associated with a “set alphabet of 5 15 letters” - (A, B, C, D, E).
It is possible to define a bristle letter mapping for a set of bristles (for example, the “inner field” or any other set of bristles), where each bristle is mapped with a respective letter, based on physical properties - i.e., height, or width, or material flexibility. Here, the following notation is defined: MAPPING (physical property, A) - where "physical property" is selected from "height" or "thickness" or "material flexibility", and "A" is a positive integer that defines the number of quanis, so if N = 3, that means 3 quanis, if N-4, this is referring to 4 quanis (or quartiles), if N = 5, that means 5 quanis.
The "quanil edge" for N quanis refers to the value whose device, from 2.5 one quanil of the other - for the "FIRST MAPPING SCHEME" (which can also be referred to as MAPPING (height, 4), constitutes three "edges of quanis ”for the set of bristles in figure 5 (ie, the internal field) - 11.3 mm, 11.3 mm and 9.3 nun. Thus, a mapping scheme, MAPPING (physical property TV), in general, it can provide Nl "edges of quanis".
A non-exhaustive list of mapping schemes that can be considered includes, but is not limited to, MAPPING (width, 5), MAPPING (height, 8), MAPPING (flexibility, 2), etc.
These mapping schemes can be applied to any “mapped set” of bristles, including any set of bristles disclosed herein - for example, any combination of features or limitations of any set of bristles disclosed herein (i.e., an explicitly disclosed combination or any other combination).
The term “mapped set” of bristles does not imply any physical limitations on the bristles (ie, physical property of the bristles and / or their distribution, or any other characteristic of the bristle) - instead, the term “mapped set” of bristles bristles is used to describe the mathematical construction of “bristle mapping”.
Any set disclosed here can be a “mapped set”.
A "mapped set" of bristles can provide any feature or combination of features disclosed herein - those features or combination of features may include, but are not limited to, any combination of height features, and / or any combination of flexibility features of material, and / or any combination of width characteristics and / or density characteristics, which describe the density of implantation of the bristles. These features include, but are not limited to, height characteristics, characteristics relating to the density with which the bristles are implanted, bristle count characteristics, bristle width characteristics, bristle shape characteristics, and any other characteristics or combinations thereof.
In addition, alternatively or additionally, in some embodiments, the “mapped set” of bristles may include one or more of the following characteristics: (i) at least 60%, or at least 70%, or at least 80%, or at least 90%, or at least 99% of the bristles have a height that is above a minimum height value - for example, at least 3 mm, or at least 4 mm, or at least 5 mm, or at least 6 mm , or at least 7 mm; and / or, (ii) at least 60%, or at least 70%, or at least 80%, or at least 90%, or at least 99% of the bristles have a height that is below a height value maximum - for example, a maximum of 25 mm, or a maximum of 22 mm, or a maximum of 20 mm, or a maximum of 18 mm, or a maximum of 17 mm, or a maximum of 16 mm, or a maximum of 15 mm; (iii) at least 60%, or at least 70%, or at least 80%, or at least 90%, or at least 99% of the bristles have a thickness that is of value above a minimum thickness value - for example , of at least 0.3 mm, or at least 0.4 mm, or at least 0.5 mm, or at least 0.6 mm, or at least 0.7 mm; or at least 0.85 mm, or at least 1 mm; and / or (iv) at least 60%, or at least 70%, or at least 80%, or at least 90%, or at least 99% of the bristles have a height that is below a maximum height value - for example, a maximum of 25 mm, or a maximum of 22 mm, or a maximum of 20 mm, or a maximum of 18 mm, or a maximum of 17 mm, or a maximum of 16 mm, or a maximum of 15 mm. A discussion about Vizinhancas das Cerdas
It was some modalities, for "any bristle (£>) supplied" and any set of BrSet bristles (i.e., including the set of all hairbrush bristles or some subset of bristles - any set disclosed here having any combination of features disclosed herein - for example, any “mapped set” of bristles), it is possible to define a “bristle neighborhood” for the bristle (b), according to any criteria listed below or any combination (including explicitly listed combinations or any other combinations). (i) “neighboring bristles” may be required to satisfy a criterion of “greater proximity than a maximum distance” - that is, bristles whose distance from the bristle (b) is less than a maximum distance - for example, less than 1, 5 cm, or less than 1.25 cm, or less than 1 cm, or less than 7.5 mm, or less than 6.5 nun, or less than 5 mm, or less than 1.5 times the average height of the bristle for the BrSet set (indicated by AH_BrSet) or less than 1.2 times, or less than 1.1 times, or less than 1 time, or less than 0.9 times, or less than 0.8 times, or less than 0.7 times, or less than 0.6 times, or less than 0.5 times AH_BrSeb, and / or (ii) “neighboring bristles” may be required to satisfy a “beyond a minimum distance” criterion - that is, bristles whose distance from the bristle (b) exceeds a minimum distance - for example, at least 1.5 mm, or at least 2 mm, or at least 2.5 mm, or at least 3 mm, or at least 10 %, or at least 15%, or at least 20%, times the set AH_BrSet and / or (iii) the “ neighboring bristles ”may be required to satisfy a“ bristle classification criterion ”- that is, when N is a positive integer, it may be possible to limit the“ neighborhood element ”with respect to a set of BrSet bristles, and a“ given bristle ”(b) for the / V-esy bristles closest to the bristle (b), where N is any positive integer (for example, 2, 3, 4, 5, 6, 7, 8, 9 or 10, or any other integer) - this constitutes the absolute closest bristles or the closest bristles, whose distance from (b) exceeds any minimum distance listed above.
The BrSet set can be any set of bristles disclosed herein, and / or have any combination of characteristics (for example, bristles from the “inner field”), including, without limitation, height characteristics, implantation density characteristics , etc. In one example, BrSet is the set of all bristles in a given region that provides any combination of the features disclosed here - for example, all bristles having any minimum height and / or any minimum thickness, and / or any maximum height, and / or any maximum thickness disclosed herein. The BrSet count can be any “bristle count” disclosed here - for example, at least 100, or at least 150, or at least 200, or at least 250 bristles.
In a specific example, it is possible to define "neighboring bristles" as bristles within a region of annular shape - that is, in which the distance exceeds any "minimum distance" (ie, the inner radius of the ring) and also and less than any "maximum distance" (that is, the outer radius of the ring).
With reference to figure 15, it is noted that, optionally, it may be possible to eliminate from a neighboring bristle Bl, any bristle B3, where: B2 & an element of the vicinity of bristle B7; and (ii) B2 ’’ blocks ”the bristle B3 - for example, B1-B2-B3 €“ substantially collinear ”.
As noted earlier, the distance between the bristles is measured along the local surface and is not necessarily a Cartesian distance (that is, for cases where the bristle retaining surface is not flat).
In one example, the “inner radius” of the annular region is equal to 1.5 mm, or equal to 2 mm, or equal to 2.5 mm, or equal to 3 mm, and / or the “external radius” of the region annular and equal to 15 mm or 12 mm, or equal to 1 cm, or equal to 8 mm, or equal to 7.5 mm, or equal to 6 mm. Any combination is possible.
In one example, the “inner radius” of the annular region is equal to 5%, or 10%, or 20%, or 25%, or 30% of the AHJ3rSet set and / or the “outer radius” of the annular region is equal to 150%, or 120%, or 100%, or 90%, or 80%, or 70%, or 60%, or 50%, or 40% of the AH_BrSet set. Any combination is possible.
Figure 1A illustrates one of the neighboring bristles of bristle B7, where neo “inner ring radius” and r2 and “outer ring radius”.
Figure 16B illustrates a subset of bristles of figure 16A, and figure 16B illustrates the concept of "source-destination vector". In figure 16B, the vector of B7 pa.ta.B2 is the “source-destination vector” of B2 in the vicinity of 57; B7 to B3 and the “source-destination vector” of B3 in the neighborhood of B7.
Each bristle in a neighborhood of a “given bristle” (in figure 16 the “bristle supplied” and B7) and associated with a respective “source-destination vector”. Neighboring Bristles
In some modalities, it is possible to arrange the bristles of a neighborhood, so that the closest bristle in the neighborhood is the "first bristle" in the neighborhood, the second closest bristle in the neighborhood is the "second bristle" in the neighborhood, etc. In the case of a "link", it may be possible to use the "arbitrary vector 10 V" as a "link breaker", so that the bristle with the smallest V angle (in the clockwise direction) is "anterior in order ”than the bristle with the greatest angle of V. In this example, even if D1STANCIA (57.5 <S) - DISTANCIA (57.577), B8 would be earlier in a neighborhood order for a neighbor of bristle B7 (ORDERING SCHEME 7).
In another example (ORDERING SCHEME 2), it is not necessary to use the distance from the “bristle provided” (in figure 16, this bristle is 57) in order to compute an order of bristles in a neighborhood. In ORDERING SCHEME 2, each neighborhood bristle is ordered only according to an angle between the "Arbitrary Vector" and a respective "source-destination vector". The angle is made from the arbitrary vector to the source-destination vector of the bristle in the clockwise direction - the bristles having a lower angle value (that is, between the "Arbitrary Vector and the source-destination vector of the bristles" ) receive a smaller number of points than the bristles having a higher angle value.
Thus, the source vector B7-B4 has a lower value (and thus 25 receives a preferable or higher rating) than the vector B7-B8. Since B7-B3 6 is collinear in the same direction as the arbitrary vector, it will have an 'zero angle' and will receive the most preference. With reference to figure 16A, for the neighborhood ordered around bristle B7, the bristle relationship “inside the ring” can be ordered in a “clockwise manner”, with respect to an arbitrary vector V, to provide the following orderm bristles (B3, B4, B8, B12, Bll, BIO, B6 and B2) (see step s919 of figure 17).
Bristle B3 is first in the list due to the fact that the angle between the source-destination vector of B7-B3 and in this case zero degree. For the “source-destination vector” of B7-B4, the angle between the “source-destination vector” of B7-B8 and the arbitrary vector is 45 degreesS. For the “source-destination vector” of B7-B4, the angle between the “source-destination vector” of B7-B8 and the arbitrary vector is 90 degrees. Bristle Mapping in Words using Neighborhood Selection, Sorting Bristles within a Neighborhood
Figure 17 illustrates a word formation routine.
In some embodiments, for a set of BrSet bristles (which by itself can be selected using any criteria and may have any properties of bristle sets, or of the bristle sets disclosed here - for example, density, height, thickness or any other properties) and an arbitrary vector V and a direction (that is, clockwise or counterclockwise - if no direction is specified, the pattern is “clockwise”, as discussed in the previous section), and it is possible to map each bristle of the BrSet bristle set in a respective word, as follows: (i) first, a bristle neighborhood relative to the BrSet set is determined using any technique disclosed here (see step S911 in figure 17 - and any other “selection technique of neighborhood ”can be used); (ii) optionally, redundant bristles (see figure 15) are eliminated from the neighborhood using any "substantially collinear bristle tolerance" (see step S915 in figure 17); (iii) the neighborhood is ordered according to any criterion - for example, relative to an arbitrary vector V and a direction (standard and hourly direction) - see step S919.
For a bbase bristle and a positive N integer (for example, N - 2, or 3, or 4, or 5, or 6, or 7, or any other value), this will produce an ordered sequence bprimetro_ yizinho> bsegiindo ^ vizinhOf - bfl-eslnio_yizinho-
In step S923, the letter of any letter of bristle (bristle) can be computed using any mapping scheme described in the previous section entitled '' Mapping Bristles to Letters, according to Material Height, Thickness or Flexibility '(MAPPING ( height, N} or (MAPPING (width, N} or (MAPPING (flexibility_material, H}, where N € any positive integer.
If the letter of bprimeiro_yizinho is the letter (bprfrrnitro_vUinhcf) the letter of bprimeiro- _viztnho and the letter (bsegundo_vizinh ^ and so on, so it is possible in step S9223 to compute a word PAIA VRA (bbase) as follows: (i) the ordered concatenation of the following letters: le.tra (bhase ) detra (bfirst. _mwto), -. letter (6Ar.c,! & m0 ^, K; 1 &) (this means “INCLUDE BASE ACTION PROGRAM”, which is also in step S923; or (ii) the concatenate ordered of the following letters: letter (bprimei ■■ ro_vjzinfo), - letter (6 #. endsimo_vizmho), not including the letter (bbase) at the beginning (this means “OMIT1R PROGRAM FOR BASE ACTION”).
With reference to figure 18, it can be observed that, optionally (see step S915 in figure 17), it is possible to eliminate the “neighboring bristles of substantially redundant angulation”. Thus, if there are two bristles whose source-destination vector is less than 30 degrees, or less than 20 degrees, or less than 15 degrees, it may be possible to disqualify the 2 most distant bristles. In the example of figure 19, it may be possible (according to step S915) to eliminate (that is, for the neighborhood ordered around bristle B7) bristle B22, in favor of bristle b21, due to the fact that B21 is closed and the angle between the source-destination vectors is less than 30 degrees, or less than 20 degrees, or less than 15 degrees, or less than 10 degrees.
In figure 16A, the “2 neighboring ordered bristles” for bristle B7 (that is, relative to the arbitrary vector in figure 16A) are {B7, B3} (since N bristles always include “given bristles”, for which the other bristles are “next” as the first ordered neighborhood bristle, the 3 ordered neighborhood bristles for bristle B7 are {B7, B3.B4}, etc.
Each bristle can be mapped to a respective letter A, B, C or D, based on 5 height, or thickness / width, or material flexibility. Thus, it is possible for a neighborhood of N bristles around a “given bristle” to produce a word of N + 1 letters from the given bristle and its neighbors (i.e., another “ordered neighborhood”). If the bristle height letter B7 is "A", the bristle height letter B3 will be "B", and the bristle height letter B4 will be "D", then the 3 letter word for the neighborhood will be " ABD ”. Discussion of Conibinatory Associated with Ordered Words
As discussed above, the phrase “bristles are implanted within the selected area, so that the heights of the bristles vary in a substantially random manner and are independent of location” (each height or width / thickness or material flexibility of the bristles) is correlated with the lack of a discernible visible pattern (different from a “random” pattern) at the heights of the falls (for example, the “inner field” of the brush in figures 1 and 2).
Without any limitation to this definition, it may be possible in some modalities to provide some kind of mathematical definition that features a substantially disordered or substantially random variation of heights (or material thickness or flexibility).
An important feature provided by some modalities is that for a given set of bristles (for example, inner field or any BrSet set, or any set disclosed here, having any feature or combination of features), the “words of height” (ie c, words formed when MAPPING («Ztwra, A) and used in step S923), and / or the“ words wide ”(ie, words formed when MAPPING (paZav7't s de seta, N) and used in step S923), and / or the “material flexibility words” (ie words formed when MAPPING (material flexibility.N) is used in step S923) are not often repeated. This can be indicative of a high degree of entropy or randomness.
For 3-letter, 4-letter words, it is possible to do 43 = 64 3-word “order”.
For 4 letter words of 4 letters, it is possible to do 44 = 256 4-word “orderings”.
For 5 letter words of 4 letters, it is possible to make 4: ’= 1024 5 word orderings.
This low repetition characteristic can therefore indicate a variation in height or width or flexibility of semi-random or random material.
For the specific case of MAPFAMENTO (aZ / z / r «, 4), for the brush of figures 1 and 2, for the“ inner field ”where the bristles show the height distribution of figure 5, the number of different words in a “inner field” region was computed. The results of the “3 letter neighborhoods” around the 300 bristles in figure 3 are indicated in Appendix B, for the specific case in which the “height” and the physical property of the letter MAPPING function. The results of the “4 letter neighborhoods” around the 300 bristles of figure 3 are indicated in Appendix C, for the specific case in which the “height” and the physical property of the letter MAPPING function.
If the distribution of height or width or flexibility is ordered, then most words will be repetitions, and only a relatively "small" number of words can appear in a larger set.
It is noted that for the brush of figures 1 and 2 (ie, for which “results” are shown in the Annexes), the brush lengths (or material widths or flexibilities) may have random or semi-random properties (ie , mathematically random), thus, they are likely to be relatively “little repeated words”.
So, for example, for 3-letter, 4-letter words, a set of 300 bristles (where the entire “vocabulary” and 64 words) can include most possible words - for example, at least 30 different words, or at least 40 different words, or at least 50 different words, or at least 55 different words. This can be true for any physical property for MAPPING (prqprz £ Z / ar / e_Jzxzc «, 4).
So, for example, for words of 4 letters of 4 letters, a set of 300 bristles (in which the entire “vocabulary” and 256 words) can include a large number of possible words - for example, at least 150 different words, or at least 175 different words, or at least 200 different words, or at least 225 different words.
Thus, if the bristles have mathematically random properties, there will be few repetitions and the number of "different words" can be of the order of magnitude of the size of the vocabulary.
Also, it may be possible to analyze 30 or 40 bristle subsets of any "bristle set", having any combination of characteristics disclosed herein, for example, the subset can be implanted with a substantially constant bristle density on the brush surface. Combinatory Characteristics Correlated to “Ordered Neighborhoods”
The term “paiavras-2” refers to a two-letter word; the term "3-word" refers to a three-letter word; the term "4-word" refers to a four-letter word, etc.
In one example, for 30 bristle subsets of any bristle set, using the mapping function “MAPPING (physical_ property, 4y for 3 words, there can be at least 10, or at least 15, or at least 17 different 3-letter words for the 40 subsets of bristles, for any physical property.
For a MAPPING function (physical_ property, 4) (that is, height or width or material flexibility) and for a “word length” from and to an arbitrary vector V, and for an action program (the “PROGRAM INCLUSION A BASE ACTION "and the pattern), and for a tolerance (i.e., from figure 15 and step S915 in figure 17, the pattern is 20 degrees for" substantially collinear bristle tolerance ") and for a planning order (the default and DIRECTION TIME), and for a neighborhood selection action program (see step S911 - this may include defining the inner and outer radii of the rings), a set of 40 bristles (for example, 5 which is one subset of any set of bristles), referred to as 40-SET, and considered to have a “substantially varied resulting word set”, if there are at least 10, or at least 15, or at least 17 different 3-letter words, or at least 22 or at least 25 different 3-letter words for the subset of 40 bristles, for any physical property (i.e., height, or width, or material flexibility). If for at least one arbitrary vector V, there are at least 10 different 3 words, this is “LEVEL VARIETY 1 for 3 letter words in a 4 letter alphabet, with respect to a physical property”. If there are at least 15 different 3 words, this is “LEVEL 2 VARIETY for 3 letter words from a 4 letter alphabet”. If there are at least 15 different 17 3 words, this is “LEVEL 3 VARIETY for 3 letter words from a 4 letter alphabet”. If there are at least 22 different 3 words, this is “LEVEL VARIETY 4 for 3 letter words in a 4 letter alphabet”. If there are at least 25 different 3 words, this is “LEVEL VARIETY 5 for 3 letter words in a 4 letter alphabet”. The term “variety” refers to 20 many different words within the subset of 40 bristles.
This can also occur with respect to the R (internal) and R (external) rays of a "neighborhood defining ring".
For a MAPPING function (proprzetWe_f'isica, 4) (ie, height or width or material flexibility) and for a “word length” of 4, for 25 an arbitrary vector V, and for an action program (a “INCLUSION OF THE BASE ACTION PROGRAM” is the standard), and for a tolerance (ie, from figure 15 and step S915 from figure 17, the standard is 20 degrees for “substantially collinear bristle tolerance”) and for a ordering direction (the default and DIRECTION TIME), and for a neighborhood selection action program (see step S911 - this may include defining the inner and outer radii of the rings), a set of 40 bristles (for example, that and a subset of any set of bristles), referred to as 40-SET, and considered to have a “substantially varied resulting word set” if there are at least 10, or at least 15, or at least 20 different 3-letter words , or at least 25 or at least 30 different 3-letter words for the subset of 4 0 bristles, for any physical property (i.e., height, or width, or material flexibility). If for at least one arbitrary vector V, there are at least 10 different 4 words, this is “LEVEL VARIETY 1 for 4 letter words in a 4 letter alphabet, with respect to a physical property”. If there are at least 15 different 4 words, this is “LEVEL 2 VARIETY for 4 letter words from a 4 letter alphabet”. If there are at least 20 different 4 words, this is “LEVEL VARIETY 3 for 3 letter words in a 4 letter alphabet”. If there are at least 25 different 4 words, this is “LEVEL VARIETY 4 for 4 letter words from a 4 letter alphabet”. If there are at least 30 different 4 words, this is “LEVEL VARIETY 5 for 4 letter words in a 4 letter alphabet”. The term “variety” refers to many different words within the subset of 40 bristles.
This can also occur with respect to the R (internal) and R (external) rays of a "neighborhood defining ring".
In some embodiments, a field of bristles (for example, including at least 100, or at least 150, or at least 200, or at least 250 bristles) having any of the properties disclosed herein, may include multiple different subsets of 40 bristles, each which can, separately, present a level of variety within a neighborhood (for example, defined by the R (internal) and R (external) rays).
In some embodiments, a field of bristles (for example, including at least 100, or at least 150, or at least 200, or at least 250 bristles) may have any number of subsets of 40 disunion bristles not required, each of which may , separately, present a level of variety within a neighborhood (for example, defined by R (internal) and R (external) rays).
If a set, COVERED SET (for example, the inner field) is "substantially covered" by 40 subsets (that is, with respect to a physical property, neighborhood definition scheme, number of letters in a word, numbers of letters) , then at least 40%, or at least 50%, or at least 60%, or at least 70%, or at least 80%, or at least 90% of the bristles of the COVERED ASSEMBLY constituting an element of a subset of 40 bristles, having any property disclosed here. Additional Discussion
Any result or characteristic of the present section can be true in relation to at least one arbitrary vector V (in figures 16 and 19, the “arbitrary vector” is pointed upwards, although this is arbitrary). In some modalities, any result (that is, correlated to a number of different words) can be true for at least 2 of 4 arbitrary vectors arranged in the unit circle in intervals of 90 degrees (or at least 3, or all 4 vectors) . In some embodiments, any result (i.e., correlated to a number of different words) can be independently true for a majority (or a substantial majority of at least 60%, or at least 70%, or at least 90%) of a set of 36 arbitrary vectors arranged in the unit circle at 10 degree intervals.
For a subset of the population (P) of 40 bristles, there can be at least 10, or at least 15, or at least 17 different 3-letter words for the subset of 40 bristles - that “minimum number” of different characteristics of 3-letter words (each 3-letter word maps an “ordered neighborhood” around a respective bristle, for a subset of 40 population bristles) can be independently “repeated” for at least 2, or at least 3, or at least 4, or at least 5 different subsets of 40 bristles from the bristle population (P), where each subset of 40 bristles independently exhibits the “low neighborhood repetition attribute”, to independently display at least 10, or at least 15 , or at least 17 different 3-letter words, for each of at least 2, or at least 3, or at least 4, or at least 5 different subsets of 40 bristles from the bristle population (P). In some embodiments, at least 40%, or at least 50%, or at least 60%, or at least 70%, or at least 80%, or at least 90% of all bristles in the “bristle population” of the field internal (that is, within a "selected area" on the brush surface), they are part of one or more of these subsets of 40 bristles of independent "low repetition of heights in orderly neighborhood", described in the present paragraph of words-3 ( ie 3 letter words).
For a subset of the population (P) of 40 bristles, there can be at least 10, or at least 25, or at least 30 different 4-letter words for the subset of 40 bristles - this “minimum number” of different characteristics of 4-letter words for a subset of 40 bristles of the population can be independently “repeated” for at least 2, or at least 3, or at least 4, or at least 5 different subsets of 40 bristles of the bristle population (P) , where each subset of 40 bristles independently displays the “low neighborhood repetition attribute”, to independently display at least 5, or at least 30 different 4-letter words (each 4-letter word maps an “ordered neighborhood” around a respective bristle), for each of at least 2, or at least 3, or at least 4, or at least 5 different subsets of 40 bristles from the bristle population (P). In some embodiments, at least 40%, or at least 50%, or at least 60%, or at least 70%, or at least 80%, or at least 90% of all bristles in the “bristle population” of the field internal (that is, within a "selected area" on the brush surface), they are part of one or more of these subsets of 40 bristles of independent "low repetition of heights in orderly neighborhood", described in the present paragraph of words-4 ( ie 4 letter words).
For subsets of the population (P) of 100 bristles, there can be at least 40, or at least 50, or at least 60, or at least 70, or at least 80 different 4-letter words for the 100-bristle subset .
This "lack of repetition of ordered neighborhood characteristics" discussed in terms of different words may be contrary to standard height brushes, where "words" can repeat themselves.
