    Field of the Invention
    [001] The present invention relates to a device to monitor the use of a toothbrush, in order to provide the user with general information on how the brushing was performed. Description of the State of the Art
    [002] Toothbrushes with monitoring devices have been known for some time, which provide the user with a general idea about the result of brushing. These devices can employ, for example, acceleration sensors, timers and pressure sensors, in order to obtain measurement data during tooth brushing.
    [003] However, the process of determining the brushing result, in other words, how satisfactory the user has been with tooth brushing, has been considered a challenging task. In addition, the costs and maintenance of the used device must be kept within reasonable limits.
    [004] In addition, improvements can still be made with respect to the accuracy and costs of the device, with respect to known monitoring devices. Summary of the Invention
    [005] An objective of the present invention is to provide an improved monitoring device to determine the result of tooth brushing. This objective is achieved through a monitoring device.
    [006] This monitoring device uses the possibility of identifying the surface of the teeth being brushed within a dental region, based on the inclination of the toothbrush, compared to the gravitation of the earth during brushing cycles. When recording the number of brushing cycles with specific records of the surface of the teeth, information is obtained on the number of brushing cycles that each dental surface is submitted to within the dental region. The recorded number of brushing cycles can then be compared with specific dental surface reference values in order to assess how satisfactory the toothbrushing has been successful. Thus, as a result, a cost-effective monitoring device is provided, being a solution that saves space and energy, for a reliable monitoring of a tooth brushing. Brief Description of Drawings
    [007] In the following, the present invention will be described in greater detail by way of example, with reference to the accompanying drawings, in which: - figure 1 illustrates dental regions in one modality; figure 2 shows an embodiment of an output device; figure 3 illustrates a modality of a toothbrush with a monitoring device; figure 4 shows a coordinate system; figure 5 represents a block diagram illustrating a modality of a monitoring device; and - figure 6 represents a flow chart illustrating the operation of a monitoring device. Description of at least one modality
    [008] Figure 1 illustrates dental regions in one embodiment and Figure 2 illustrates one embodiment of an outlet device 27.
    [009] In the modality of figure 1, by way of example, the teeth were divided into four dental regions R-U, L-U, R-D, and L-D. The dental regions, in the present case four, can be identified as upper left L-U, lower left L-D, upper right R-U and lower right R-D. In many cases, a sufficient general idea can be provided to the user of a toothbrush, by indicating that one (or more) of these four regions has not been adequately brushed.
    [0010] In one embodiment, each of the four dental regions R-U, L-U, R-D and L-D comprises three previously defined dental surfaces that need brushing. Therefore, in figure 1, each region comprises an outer surface 1 to 4, an inner surface 5 to 8, and a chewing surface 9 to 12.
    [0011] In the following examples, the user brushes his teeth by brushing the four dental regions R-U, L-U, R-D, and L-D in a predetermined order, or, alternatively, indicating to the monitoring device which region is currently being brushed. The monitoring device, consequently, knows the tooth region being brushed. However, the user can brush the dental surfaces 1, 5, 9; 2, 6, 10; 3, 7, 11; or 4, 8, 12 within a dental region R-U, L-U, R-D, and L-D in any desired order, even if changing several times between the internal, external and chewing surfaces, while brushing the specific dental region.
    [0012] The output device used in the monitoring device can indicate the result of the brushing to the user in any convenient way, which allows the user to determine whether or not the brushing of a dental region RU, LU, RD or LD was well accepted . Such an output device can include at least one of the following: an LED (Light Emitting Diode), a sound generator to produce sounds or music, and a voice generator. The output device can be physically located in a module that moves along with a toothbrush, or alternatively, that module can include a wired or wireless data transmission interface to transmit data to an external output device, which indicates the result of the brushing to the user.
    [0013] In the example in figure 2, it is assumed by way of example, that the output device 27 can include LEDs or an LED monitor, with a sector 13 to 16 for each dental region shown in figure 11. If sector 13 is lit red in the output device shown in figure 2 after brushing, the user will understand that the RU region shown in figure 1 requires, for example, more intense brushing. Similarly, if another sector is lit red in the output device shown in figure 2 after brushing, the user will understand that the region (LU) shown in figure 1 requires, for example, even more intense brushing. Acceptable brushing can be indicated by lighting in a different color, such as, for example, green. Alternatively, other indicative colors and lighting modes can be used, in order to provide the user with feedback information, such as a light that blinks versus a light that presents itself in a stable way, a bright disposition versus an unclear disposition. , and others.
    [0014] If LEDs are used in the output device 27, the output device may include a pair of LEDs for each dental region. In this case, each pair of LEDs includes a LED of a first color to indicate a successful brushing of that region (the region that corresponds to 1/4 of the total region), and a LED of a second color to indicate an unsuccessful brushing. of said region.
    [0015] Figure 3 illustrates a toothbrush modality 17 with a monitoring device 18 and figure 4 illustrates an X-Y-Z coordinate system for a brush head 19 of that toothbrush.
    [0016] In the modality of figure 3, the monitoring device 18 was produced in the form of a separate module, containing the necessary electronic components and a battery, which was embedded within the axis of a manual toothbrush 17. Thus, the bristles 20 of the brush head 19 move with said brush head 19 and the monitoring device 18 moves with each movement of the brush head. However, this is just one example of how a monitoring device 18 can be arranged on a toothbrush. Alternatively, the monitoring device can be an extension of the toothbrush shaft, or be connected to the toothbrush in some other way. The brush head 19 can be detached from the toothbrush handle 17 in order to allow different people with their own brush head to use the same toothbrush handle 17.
    [0017] In figure 3, the monitoring device, for example, is provided with an input device 21, such as a push button, and an output device 27, as illustrated in figure 2. The input device, however, it can be located on a separate device (not shown in figure 3), in which case the monitoring device may include a wired or wireless data transmission interface 22, for receiving signals from the separate input device.
    [0018] For reasons of better understanding, in figure 4, the direction of the X axis is generally the same as the direction of the bristles 20 on the brush, the direction of the Y axis is perpendicular to the X axis and, generally, the same as the direction longitudinal direction of the brush head 19, which in the example shown is the direction of the center line of the tubular body of the toothbrush 17, and the Z axis is generally directed laterally in relation to the brush head, thereby forming an angle of 90 ° with the X and Y axes. However, it should be noted that the exact directions of the axes are not important for the monitoring device itself, but are only defined to allow the following example to be understood.
    [0019] Figure 5 is a block diagram illustrating an example of a monitoring device 18. The monitoring device can be integrated within a toothbrush, as in figure 3, or, alternatively, consist of a separate component which is attached to the toothbrush. As a separate component, the monitoring device can be detached from a first toothbrush and attached to another toothbrush. In such a case, the monitoring device may be a part of an interchangeable toothbrush handle.
    [0020] In this example, the monitoring device comprises a signal conditioner 23, which controls the operation of the monitoring device 18. Signal conditioner 23 and a comparator 24 can be implemented with circuits, computer program or a combination of program of computer and circuits. In the last two cases, a processor arranged on a computer can perform the tasks of signal conditioner 23 and / or computer 24 under the control of software. The computer can be an independent processor, for example, embedded within a basic device, or a general purpose computer. The signal conditioner and the comparator can therefore physically consist of a single part.
    [0021] Signal conditioner 23 carries low pass and high pass filtering, for example, with one or more digital filters. At least one of the filters can be of the type: y (t) = y (t-1) * (1 - 1 / k) + x (t) / k, where: y (t) is the output in the time step t, x (t) is the entry in the time step tek is a filter factor, respectively. At least one of the filters can be of a type of: z (t) = x (t) - y (t), where: z (t) is the output in time step t, x (t) is the input in the time step tey (t) is a low pass filtered signal, respectively.
    [0022] An acceleration sensor 25 is coupled to the device for measuring tooth brushing patterns. A three-axis acceleration sensor 25 can be used to detect the inclination of the toothbrush during use, such as the angles with which the toothbrush and the monitoring device attached to it are maintained during use, when compared to the gravity of the earth. In another example, the three-axis acceleration sensor 25 measures the toothbrush's cyclic and / or non-cyclic movement. The acceleration sensor can be of the type, for example, CMA3000, available from VTI Technologies Oy, PO Box 27, FI-01621, Vantaa, Finland. The output of a three-axis acceleration sensor can be expressed as: measured = a + g + aε, 1 in which the measured output vector (measured, three components) corresponds to the sum of the acceleration a of an object, gravity vector ge an aε error term, all in the local coordinate system of the monitoring device.
    [0023] From equation 1, an acceleration sensor can be used to measure the inclination (when the change in speed a is known) and acceleration (when the gravitational acceleration in a brush structure is known). Additional sensor components that increase the cost and take up space are not required to track the movement or position of a toothbrush, so the monitoring device can include a three-axis acceleration sensor 25 as the only sensor. An advantage of a device using only an acceleration sensor is that the costs of producing the device are reduced. Another advantage is that using an acceleration sensor without any other orientation or displacement sensors saves space. Compared to some other approaches, a third advantage is ultra-low energy consumption.
    [0024] In the measurements made with the monitoring device 18, the acceleration is supposed to be noisy, which affects the measurements of inclination or angle. During tooth brushing, the acceleration sensor 25 can measure tooth brushing patterns, which can be recorded or supplied as comparator data 24. Comparator 24 can also receive tooth brushing pattern reference data, in other words, reference values, of a memory 26. Memory 26 can be a recording device that is coupled with the acceleration sensor 25 and / or signal conditioner 23 to maintain the standard reference data. The signal conditioner 23 can perform low and high pass filtering functions, as well as leveling trigger functions in the acceleration data, in order to obtain relevant data and standard brushing parameters.
    [0025] Thus, for example, reference data or standard toothbrush reference values, stored in memory 26, can be compared with data produced during normal daily use of a toothbrush, as soon as the use of said toothbrush is used. teeth has been finalized. In an example of standard toothbrushing reference data, standard toothbrushing reference data can also indicate the time spent (for example, seconds) for brushing each tooth region, the number of brushing cycles per tooth region , and the order of brushing (transfer from one position to another). The comparison between the data of the toothbrushing pattern during use, with the reference data or standard values of toothbrushing reference is used to provide a general observation of what happened to the user through the output device 27. The device of toothbrushing Monitoring 18 can be configured to automatically inform the user about brushing results, using an LED, a plurality of LEDs, or a monitor, by indicating the result for a predetermined period of time after brushing has been completed, as determined, for example, by a waiting time, a return to a base or a switch.
    [0026] Instead of a visual indicator, the output device 27 can consist of an indicator that produces sound, such as a cicada producing a predetermined horn sound, or a voice generator producing instructions after tooth brushing. Such a cicada or voice generator can be used to indicate a successful brushing or an unacceptable brushing. In this way, the user can be provided with immediate information about brushing.
    [0027] In some modalities, the monitoring device shown in figure 5 may include a timer 28 to measure the duration of brushing in a specific dental region. This allows a comparison to be performed with a reference value representing a reference duration, which indicates whether or not the user has brushed a tooth region long enough.
    [0028] The monitoring device 18 shown in figure 5 can also include an interface 22 to send the result of the comparison to a remote device, where the output device 27 and / or a separate brushing data storage unit are located. located. Consequently, the user can receive information about what happened through an output device located locally, in connection with the signal conditioner and the comparator or, alternatively, through an output device that is remotely located, or through local and remote output devices. .
    [0029] In the case of a wired interface to a remote device, interface 22 may include electrical contacts, which are used by the monitoring device 18, to communicate with the remote device. Alternatively, in the case of a wirelessly connected interface, interface 22 may include a radio transmitter, to transmit the measurement result via a radio path to the remote device.
    [0030] The monitoring device18 also includes an input device 21 for receiving user inputs, such as, for example, a button press, for the user to access, for example, a selection mode (for example, teaching, brushing, memory scrolling), or indication of starting or stopping events). These inputs can be used to set the monitoring device 18 in a teaching mode, which can be used to collect the user's preferred brushing pattern data. The first mode can be continuous, meaning that the data is stored as reference values continuously, including the measured tooth brushing patterns, or it can be used to selectively store the data. Selective data can be used according to dental hygiene guidance, dentist or parent supervision, to ensure, for example, proper brushing. After activation of the input device 21, the acceleration sensor 25 is configured to measure and send the toothbrushing pattern data (for example, data relating to a toothbrush inclination), to the signal conditioner 23, which you can process them and store them in memory 26 for subsequent use, while using the toothbrush.
    [0031] The acceleration sensor 25 measures the brushing patterns for comparison with the reference data when the monitoring device 18 is in a second mode. The teaching mode allows the user to store individual standardized toothbrushing reference data in memory 26 as reference values. Thus, for example, after pressing the input device 21, the user uses the toothbrush to brush his teeth, as intensely as desired. A second actuation of the input device 21 can terminate the first mode. The result is that standardized toothbrushing reference data, which indicates angles at which that particular user maintains the toothbrush during use, is stored in memory 26 in the form of standardized toothbrushing data or reference values. Alternatively, the reference data can also indicate the time spent, the number of brushing cycles and the brushing order (transfer from one position to another). This individualized standardized toothbrushing reference data can be used to analyze how much that specific user will brush their teeth in the future, during daily use. Therefore, the first mode allows the user to take individual behavior into account (the toothbrush or the user's head, for example, is maintained at individual angles) during tooth brushing.
    [0032] Furthermore, by way of example, the monitoring device is supposed to produce and store the toothbrush pattern reference data in memory, since the monitoring device 18 is established for teaching and brush mode of teeth being used. However, an alternative to this is that the predefined toothbrush pattern reference data is produced on an external device and copied to the memory 26 of the monitoring device 18, for subsequent use as reference data or reference values, while the Monitoring device is used daily for brushing teeth.
    [0033] When the toothbrushing monitoring device 18 is used in daily use, a comparison can be made with the reference data kept in the memory 26 of the monitoring device 18. Additional reference data can be recorded to replace or be aggregated the first reference data. These toothbrushing patterns can be stored individually or collectively, as standardized toothbrushing reference data on a recording device. Thus, for example, a user in a specific brushing session, can store the toothbrushing patterns produced on the recording device as reference data. Alternatively, the user can add this reference data to standardized cumulative toothbrushing reference data.
    [0034] Standardized individual toothbrushing reference data can be stored for a plurality of people in the memory 26 of the monitoring device 18. In one example, an identifier of the person who used the toothbrush during teaching mode is stored in memory along with standardized toothbrushing reference data. In one example, this identifier is associated with an individual brush head 19 in a device that features a detachable brush head for each individual user. This is advantageous when several people use the same toothbrush or, in fact, the same handle as a toothbrush (with their own personal brush parts attached, such as a brush head). In this case, the monitoring device 18 may be able to automatically identify the person who is using the toothbrush, by selecting the memory 26 of the standard toothbrush reference data that best compare with the data produced when using the brush. of teeth. Alternatively, the toothbrush can include an interface that allows the user the ability to input their identifier, or the identifier is encoded in the brush head interface, in order for the monitoring device 18 to be able to select the correct ones standardized tooth brushing reference data from memory 26. Input device 21 can be used as such a type of interface.
    [0035] The monitoring device18 can be configured for self-calibration, based on the sum of the filtered acceleration vector in low pass, a = ^ (axlp2 + aylp2 + azlp2) = 1g, where axlp, aylp and azlp are the acceleration components filtered in low pass, in the orthogonal directions x, y and z, in the brush coordinate system, respectively.
    [0036] All parts of the monitoring device 18 can be encapsulated and / or integrated inside or attached to the body of an electric or manual toothbrush. Alternatively, a radio transmitter can be arranged separately from the other parts, for example, in a battery charger, frame or base of the electric toothbrush. In such an example, the interface can include contact terminals on the toothbrush, which are connected to the corresponding terminals on the battery charger, to send the result of the comparison via a wired connection, to the transmitter on the battery charger or by induction or short-range wireless communications. The radio transmitter in the battery charger then transmits this result of the comparison, via the wireless radio connection, to the remote device.
    [0037] Figure 6 represents a flow chart illustrating the operation of a monitoring device.
    [0038] In step 30, the user begins to brush a predetermined dental region or a dental region indicated by the user. The alternatives are, for example, that the dental regions are always brushed in the same order, that the monitoring device for each new dental region indicates by the exit device 27 which dental region should be brushed, or that the user using the entry 21 indicate the dental region RU, LU, RD or LD that should be brushed. In any case, the monitoring device 18 knows the tooth region being brushed, which in the present example is supposed to be the L-U region.
    [0039] In the present example, a timer 28 is supposed to be used to measure a brushing duration for a dental region, for example, how many seconds the user spends brushing the region in question, although a timer is not necessary in all modalities . If a timer is used, an alternative is to use three timers, one for each surface of a dental region. Consequently, in step 31, timer 28 is started and started and specific tooth surface counters are started (such as, set to zero). In the following explanation, it is assumed by way of example that three specific tooth surface counters are provided, one for the external tooth surface 2, one for the internal tooth surface 6 and one for the chewing surface 10.
    [0040] In step 32, the acceleration sensor 25 produces signals that signal conditioner 23 receives and processes. Signal conditioner 23 low-pass filters signals (ax, ay, az) to eliminate noise and danger of acceleration. In addition, the acceleration signal is strongly filtered at low passage, which provides the signal with no acceleration, only the gravity of the earth, in addition to deviation of the acceleration sensor and error gain. Maximum and minimum values of this signal are used to auto-calibrate the sensor parameters of the three axes X, Y and Z (1 g = 9.81 m / s2 = acceleration in free fall in the earth's gravity field), as follows: - ax (0) (= deviation) = (ax (max) + ax (min)) / 2 is calibrated to 0g, - ax (gain) = (ax (max) - ax (min)) / 2 is calibrated to 1g, - ay (0) (= deviation) = (ay (max) + ay (min)) / 2 is calibrated to 0g, - ay (gain) = (ay (max) - ay (min)) / 2 is calibrated to 1g, - az (0) (= deviation) = (az (max) + az (min)) / 2 is calibrated to 0g, and - az (gain) = (az (max) - az (min)) / 2 is calibrated to 1g.
    [0041] Now, during brushing, the X and Z components of the strongly filtered signal in low pass directly provide the brush inclination in the earth's gravity field. The acceleration Y is then filtered in high pass, by subtracting the strongly filtered signal in low pass from the original signal (ayhp = ay - aylp). For this, limiting signal levels are established. Once a positive limit is exceeded, as well as a negative limit, within a predetermined time limit, a brushing cycle is identified in step 32. In this example, a specific acceleration, a double level of transposition, in other words , two Y accelerations in opposite directions within a specified time frame, indicate a brushing cycle. At this stage, step 33 begins, where the X and Z components that are strongly filtered at low passage are analyzed. These components are used in step 33 to determine which tooth surface 2, 6 or 10 has been brushed with the identified brushing cycle. The monitoring device memory keeps a pair of sample X and Z for each dental surface 2, 6 and 10 of the dental region L-U (and also for all other dental regions). Therefore, the brushed tooth surface is determined to be a surface whose sample pair X and Z best level with the present components X and Z strongly filtered in low passage. The specific dental surface counter of the identified dental surface is used to record the brushing cycle for the identified dental surface 2, 6 or 10 in step 34, for example, by incrementing the counter of a unit. Physically, specific dental surface counters can be implemented as predetermined memory locations in memory 26.
    [0042] In step 35, a check is made to determine if the brushing of the same LU dental region continues, or if the monitoring device has signaled the user that the brushing of said dental region must end (for example, through the indication by the monitor brushing of the LU tooth region was accepted), or if the user used the input device 21 to indicate that tooth brushing of the tooth region has ended.
    [0043] As soon as, eventually, it is determined in step 35 that the brushing of the dental region in question has finished, step 36 begins. In step 36, comparator 24 compares the registered number of brushing cycles for each specific dental surface counter with the corresponding reference values in memory 26. In addition, although not necessary in all modalities, in the present example, timer 28 is checked to determine the duration of brushing in the LU dental region with a corresponding reference value found in memory 26. If all specific dental surface counters have registered a number of brushing cycles, which with sufficient precision correspond to the reference values, and also in this example, the duration of brushing with sufficient precision corresponds to the reference value found in memory 26 is then indicated by the output device 27, in step 37, that the brushing of the LU dental region has been accepted. Otherwise, it is indicated in step 37 by the output device 27 that the brushing of the L-U dental region was not accepted.
    [0044] The sufficient precision required in the comparison, in order to accept the brushing result, depends on the implementation. An alternative is that if all specific tooth surface meters register a number of brushing cycles that is at least 60 to 80% of the reference value for the tooth surface in question, and similarly, the duration (if used) of the brushing measured by the timer is at least 60 to 80% of the corresponding reference value, brushing of the dental region in question can be accepted.
    [0045] Finally, in step 38, it is determined whether the tooth regions need brushing or not. If they don't, the process can be completed. Otherwise, steps 30 to 38 are repeated for the next dental region.
    [0046] In addition to the features previously described, the monitoring device can also use the output device 27 to indicate to the user when the toothbrush has worn out and, consequently, has reached the end of its period of use. In this way, the user can be informed of when to purchase a new toothbrush or toothbrush head. An alternative to obtain this information is for the monitoring device to be configured to count the total number of toothbrushing cycles accumulated in total, and to indicate with the output device 27 that the end of the toothbrush usage time has been reached, once a specific reference number of toothbrushing cycles has been reached for the brush. In the case of a modality in which the same monitoring device can be used with another toothbrush or toothbrush head, the user, in this case, may have the opportunity to reset the accumulated toothbrushing cycles count once the toothbrush or toothbrush head has been renewed.
    [0047] Alternatively, the monitoring device can be configured to compare a present spectral distribution of brushing acceleration with a specific reference distribution previously established, and to indicate with the output device 27 the end of the period of use of the toothbrush. based on said comparison.
    [0048] It should be understood that the description above and the attached figures are only idealized to illustrate the present invention. It will be obvious to a person skilled in the art that the invention can be varied and modified, as long as there is no departure from its scope.
