Field of the Modalities Described
[0001] The modalities described refer, in general, to portable electronic devices. More particularly, the present embodiments describe release techniques that are well suited for portable electronic devices. Description of the Related Art
[0002] Recent advances in portable computing include the introduction of handheld electronic devices and computing platforms in the style of the iPad ™ tablet manufactured by Apple Inc. of Cupertino, CA, USA. These handheld computing devices can be configured so that a substantial portion of the electronic device takes the form of a screen used to present visual content while leaving little space available for a fixation mechanism that can be used to fix an accessory device.
[0003] In general, conventional fastening techniques rely on mechanical fasteners that typically require at least one externally accessible fastening feature on the electronic device to couple with a corresponding fastening feature on the accessory device. The presence of an external fixation feature can detract from the overall look and feel of the handheld computing device, as well as add unwanted weight and complexity, as well as degrade the appearance of the handheld computing device.
[0004] Therefore, we want a mechanism to releasably set at least two objectives among themselves. Summary of the Modalities Described
[0005] This document describes several modalities that refer to a system, method, and apparatus for forming a cooperative system that uses magnetic fixation.
[0006] A magnetic fixing unit is described which serves to magnetically fix a first object having a first magnetic fixing system and a second object having a second magnetic fixing system to form a cooperative system. The magnetic clamping unit includes at least one magnetic clamping system that is arranged to provide a first activation force to activate the first magnetic system and a second activation force to activate the second magnetic system. The first and second activated magnetic systems cooperate with the magnetic clamping system to releasably hold the first object and the second object together in order to form the magnetic cooperation system.
[0007] A magnetic fixation unit serves to magnetically fix at least one first and second individual electronic devices having an associated magnetic fixation feature, and the magnetically fixed electronic devices communicate with each other so that when they are magnetically fixed, they form a cooperative electronic system . The magnetic clamping unit includes a body having a first side and a second side opposite the first side, a first magnetic clamping system on a first side of the body comprising at least one first magnet arranged to provide a first activating force that serves to activate a corresponding magnetic clamping feature on the first electronic device, and a second magnetic clamping system on a second side of the body comprises at least a second magnet arranged to provide a second activating force that serves to activate a magnetic clamping feature corresponding in the second electronic device, a magnetic clamping force generated between the first and second activated magnetic systems and the corresponding magnets in the magnetic clamping unit results in the fact that the first and second individual electronic devices operate together as an electronic device cooperation.
[0008] A cover assembly is described that includes at least one hinge assembly separably connected to a host unit and a cover assembly pivotably attached to the hinge assembly having a size and shape according to the host unit. The cover assembly includes at least one cover portion pivotably attached to the pivot portion on a first pivot, a flap portion separate from the cover portion pivotally attached to the pivot portion on a second pivot other than the first pivot so that the portion cover and the flap portion rotate around their respective pivot points separately so that the cover forms a support structure that supports the host device at an angle inclined to the flap portion.
[0009] An anchoring station includes at least one base portion arranged to support a host device, the base portion including a fixing unit, the fixing unit being arranged to securely hold the device host and the base portion, a user input portion, the user input portion being arranged to receive a user input event, and a communication port, the communication port being arranged to provide a communication path between the host device and the user input portion of the base portion, and information associated with the user input event in the user input portion is passed through the communication path provided by the communication port to the device host.

[00050] Now, reference is made in detail to the representative modalities illustrated in the attached drawings. It should be understood that the following descriptions are not intended to limit the modalities to a preferred modality. On the contrary, it is intended to cover alternatives, modifications, and equivalents that may be included in the spirit and scope of the modalities described as defined by the attached claims.
[00051] The description below refers, in general, to a mechanism that fixes at least two objects properly configured among themselves. In one embodiment, this can be accomplished without the use of conventional fasteners. Each of the objects can include a fixation feature arranged to provide a magnetic field having appropriate properties. When fixation features are placed in close proximity to each other, magnetic fields can interact cooperatively based on their respective properties and can result in objects being magnetically fixed together in a desired and repeatable manner. For example, due at least in part to the cooperative nature of the interaction of magnetic fields, objects can cling together in a predetermined position and relative orientation without external intervention. For example, cooperative magnetic interaction can result in self-alignment and self-centering of objects in a desired orientation.
[00052] Objects can remain in the magnetically fixed state if a release force of sufficient magnitude is applied that exceeds the general net attractive magnetic force. However, in some cases, it may be desirable to separate objects serially (along the lines of a zipper), in which case the release force only needs to be of sufficient magnitude to overcome a net magnetic attractive force of a pair of elements magnetic at once. Connectors, such as mechanical fasteners, are not required to secure objects to each other. In addition, to avoid undue interference with the magnetic interaction between the magnetic fastening resources, at least a portion of the objects in the vicinity of the magnetic fastening resources can be formed by magnetically inactive materials, such as plastic or non-ferrous metals, such as aluminum or non-magnetic stainless steel.
[00053] Objects can take many forms and perform many functions. When magnetically attached to each other, objects can communicate and interact with each other to form a system of cooperation. The cooperation system can perform operations and provide functions that cannot be provided by the separate objects individually. In another embodiment, at least one device can be used as an accessory device. The accessory device can be magnetically attached to at least one electronic device. The accessory device can provide services and functions that can be used to increase the operability of the electronic device (s). For example, the accessory device can take the form of a protective case that can be magnetically attached to the electronic device and confine the electronic device. The protective case can provide protection for certain aspects (such as a screen) of the electronic device, as well as the electronic device as a whole. The magnetic clamping mechanism used to magnetically clamp the protective case and the electronic device can ensure that the protective case can only be attached to the electronic device in a specific orientation. In addition, the magnetic clamping mechanism can also ensure proper alignment and positioning of the protective case and the electronic device.
[00054] In one embodiment, a first object and a second object can be magnetically attached to each other so that the first object can be configured to provide a support mechanism for the second object. The support mechanism can be of a mechanical nature. For example, the first object can take the form of a platform that can be used to support the second object on a work surface, such as a table. In one embodiment, the platform can take the form of an articulation platform arranged to present the second object in a series of angles and orientations.
[00055] In one embodiment, the first object can take the form of an anchoring station arranged to attach magnetically to the second object in a particular way. The docking station can be electronic in nature in those cases where the second object is an electronic device. The docking station can provide an electrical contact that can supply power from an external power supply to the electronic device. The electrical contact can also provide a mechanism through which information can be provided to the electronic device, as well as information provided from the electronic device. For example, the docking station may include audio output devices, such as speakers to broadcast sound based on an audio signal received from the electronic device.
[00056] In one embodiment, the first object can take the form of a hanging device. As such, the first object can be used to hang the second object which can then be used as a canvas to present visual content, such as visual or still images, such as a photo, a work of art, and so on. The support mechanism can also be used as a handle to conveniently grab or hold the second object. This arrangement can be particularly useful when the second object can present visual content, such as images (immovable or visual), textual (as in an electronic book) or has image capture capabilities, in which case the second object can be used as an image capture device, such as a still or visual camera and the first object can be configured to act as a support, such as a tripod or a handle. The handle can be fixed or fixable. In one embodiment, the hanging apparatus may take the form of hooks, suction cups, or any other suitable hanging device. For example, the hanging device can be used to attach the electronic device to a bulletin board. In one embodiment, the hanging device in the form of a hook can be used to attach the electronic device to a seat cushion in an automobile, airplane, or train. In this way, the electronic device can provide visual content to those who are seated in a position to view the display screen.
[00057] In one embodiment, fixation can occur between a first and a second object, where the first object and the second object are electronic devices. Electronic devices can be magnetically attached to each other to form a cooperative electronic system in which electronic devices can communicate with each other. In one embodiment, the first and second electronic devices can be attached directly to each other. In one embodiment, a magnetic clamping unit can be used to magnetically clamp the first and second electronic devices together. Communication between the first and second electronic devices can occur before, during, and after the magnetic fixation is complete.
[00058] As part of this communication, information can be passed between the first and second electronic devices. Information can be processed in whole or in part either on the first or second electronic device depending on the nature of the processing. In this way, the cooperative electronic system can take advantage of the synergistic effect of having multiple electronic devices magnetically fixed and in communication with each other. In an implementation, communication can be performed remotely using any suitable wireless communication protocol, such as Bluetooth (BT), GSM, CDMA, WiFi, and so on.
[00059] In one embodiment, the magnetic clamping unit can pass information between the first and second electronic devices. In one embodiment, information can be provided from the magnetic clamping unit and passed to one or both the first and second electronic devices. For example, in one embodiment, the magnetic fixation unit can take the form of a magnetic binder that can be used to fix the first and second electronic devices in the form of an electronic book. As such, at least one electronic device can have a screen suitable for displayed visual content. Information, such as book content, can be passed from the magnetic binder to the electronic device. The information can cause the electronic device to operate in a manner consistent with the information.
[00060] For example, when the information provided to the first or second electronic device is associated with a specific learning class (such as math, languages, etc.), the information can cause one or both of the electronic devices to operate consistent way to class, such as presenting lessons, worksheets, and so on. For example, the first electronic device can present visual content consistent with the subject of the lesson while the second electronic device can facilitate user interaction by presenting a user input, such as a virtual keyboard, a touch sensitive input, and so on. against.
[00061] In one embodiment, the second electronic device can take the form of a peripheral device, such as a keyboard, a touch pad, a joystick, and so on. This modality may be well suited for video games presented by the first electronic device. In one mode, the magnetic fixture unit can store the information needed to start the video game, while in another mode, the magnetic fixture unit can act as a trigger. The trigger acts to start a game residing on either the first or the second electronic device.
[00062] In one embodiment, the cooperative electronic system can take the form of an arrangement of electronic devices rigidly connected to each other by means of the magnetic fixation unit. The magnetic clamping unit may include a plurality of magnetic clamping features. Each of the plurality of magnetic fastening features can magnetically interact with a corresponding magnetic fastening feature including a corresponding electronic device. In one embodiment, the arrangement of electronic devices can act as a single, unified screen (along the lines of a mosaic). In another embodiment, the arrangement of electronic devices can provide a single function or a set of functions (such as a virtual keyboard).
[00063] As an example, a first and a second electronic device can be magnetically coupled together by means of a magnetic fixation unit. The magnetic clamping unit may include a magnetic system. In one embodiment, the magnetic clamping unit can act as a trigger to activate a magnetic clamping system on each between the first and second electronic devices. In one embodiment, activation may be a result of a linked magnetic interaction between the magnetic system and each of the magnetic fixation systems. In one embodiment, the linked magnetic interaction can take the form of an interaction between magnetic fields having properties based on an arrangement of magnetic elements in the magnetic system and the magnetic fastening systems in the first and second electronic devices.
[00064] In one embodiment, the magnetic clamping unit can be formed of a foldable but firm material. In this way, a portion of the magnetic clamping unit magnetically attached to the first electronic device can be folded so that a screen on the first electronic device is presented to a user at a comfortable viewing angle of about 70 ° to 75 ° while the second electronic device remains flat on a support surface, such as a table. In this way, the second electronic device can display an entry (such as a virtual keyboard, GUI, and so on) that can be used to enter data into the cooperative system. In one embodiment, the first electronic device can display visual content according to the current state of the cooperative system.
[00065] For example, the second electronic device may have a virtual keyboard that can be used to provide input and / or data commands, and the like, to the cooperative system by magnetic attachment of the first and second electronic devices. In the case where the magnetic fixation unit is associated with a math class, for example, the information provided to the first and second electronic devices can cause the screen of the first electronic device to present the subject in question (mathematical equations to be solved , problems, etc.) to which the student can interact using the virtual keyboard presented by a screen of the second electronic device.
[00066] These and other modalities will be discussed below with reference to Figures 1 to 35. However, those skilled in the art will readily appreciate that the detailed description provided here in connection with these figures is for explanatory purposes only and should not be construed as limiting. For the remainder of this discussion, a first and a second object properly configured to magnetically fix each other according to the described modalities will be described. However, it should be noted that any number and type of properly configured objects can be magnetically attached to each other in a precise and repeatable manner. In particular, for reasons of simplicity and clarity, for the remainder of this discussion, the first object is assumed to take the form of an electronic device and, in particular, an electronic handheld device.
[00067] Figure 1 is a simplified block diagram of article 10 and electronic device 12 that can be releasably attached to each other in a desired and repeatable manner. More specifically, article 10 and electronic device 12 can be fixed to each other in a predetermined position and in a relative orientation without external intervention and without the use of mechanical fastening elements. The article 10 and the electronic device 12 can remain attached to each other if a release force is applied that exceeds the engagement between them. However, in some cases, it may be desirable to separate the article 10 and the electronic device 12 serially (along the lines of a zipper), in which case a release force can be applied that can undo the engagement between the article 10 and electronic device 12 around one fastening component at a time. For example, a fastening component can include a suitably matched pair of magnetic elements, one in article 10 and a second in electronic device 12.
[00068] The electronic device 12 can take many forms. For example, electronic device 12 can take the form of a portable electronic device. In some examples, the portable electronic device may include an enclosure 15. The enclosure 15 may abut and support the components of the portable electronic device. The housing 15 can also support at least one large and prominent screen that occupies a substantial portion of the front face of the portable electronic device. The screen can be used to display visual content. Visual content can include still images, visuals, textual data, as well as graphic data that can include icons used as part of a graphical user interface, or GUI.
[00069] In some cases, at least a portion of the screen may be touch sensitive. It is understood that the term “touch sensitive” means that during a touch event, an object (such as a finger, a stylus, and so on) can be placed in contact with or in proximity to an upper surface of the screen . The characteristics of the touch event (location, pressure, duration, and so on) can be used to provide information to the portable electronic device for processing. In some modalities, in addition to or instead of the information being provided to the portable electronic device, the information can be provided by the portable electronic device in a tactile way using, for example, tactile actuators. However, it should be considered that this configuration is by way of example and not by way of limitation since the electronic device can be widely varied. In one example, the portable electronic device is a tablet computer, such as, for example, the iPad ™ manufactured by Apple Inc. of Cupertino, CA, USA.
[00070] Article 10 can be widely varied and can take many forms, such as, for example, an accessory or clothing accessory of the electronic device 12. As an accessory, Article 10 can be configured as a cover, a platform, a docking station, a handle, an input / output device, and so on. In a particularly useful form, article 10 may take the form of a protective cover which may include a member, such as a flap, which can be positioned on the screen of the portable electronic device. Like the electronic device 12, the article 10 can also include a housing 17 that can confine and provide support for the components of the article 10.
[00071] One or both of article 10 and electronic device 12 may include fixing features. For example, article 10 can include a fixing system 13 and electronic device 12 can include a corresponding fixing system 14. Fixation system 13 can cooperate with the corresponding fixing system 14 to fix article 10 and the electronic device 12 in a releasable manner. When fixed together, the article 10 and the electronic device 12 can operate as a single operational unit. On the other hand, in separate mode, the article 10 and the electronic device 12 can act separately, and, if desired, as two individual parts. The fixing systems 13 and 14 can be configured in such a way that the article 10 and the electronic device 12 can be fixed together in a desired and repeatable manner. In other words, the fastening systems 13 and 14 can repeatedly align the article 10 and the electronic device 12 together so that they are consistently in a predetermined position with respect to each other.
[00072] The fixing features can be widely varied. Fixation can be provided by several types of couplings, including mechanical, electrical, static, magnetic, friction, and / or similar couplings. In one embodiment, the fixation cannot be seen from outside the article and / or the electronic device. For example, the article and the device may not include external visible fastening features that adversely affect the appearance and feel or decorative appearance (for example, hitches, fasteners, etc.), but, preferably, fastening features that do not can be seen from outside the article or device and therefore do not affect the appearance and feel or decorative appearance of the article or device. For example, the fixing features can be provided by attracting surfaces that do not disturb the external surfaces of the article or the device. In one embodiment, at least a portion of the clamping features uses magnetic attraction to provide part or all of the clamping force.
[00073] Fixing systems can include one or more fixing features. If multiple resources are used, the way in which they attach can be the same or different. For example, in an implementation, a first fastening feature uses a first fastening means while a second fastening feature uses a second fastening means that is different from the first fastening means. For example, the first fastening means can use a friction coupling, while the second fastening means can use magnetism. In another implementation, a first fixing feature uses a first fixing means, while a second fixing feature uses the same or similar fixing means. For example, the first and the second fixing means can be provided by magnets. Although the fixation method can be similar, it must be considered that the configuration of the resources can be different depending on the needs of the system. In addition, any number and configuration of fastening means can be used.
[00074] In the illustrated embodiment, the fixing systems 13 and 14 include at least a first set of corresponding fixing features 13a / 14a and a second set of corresponding fixing features 13b / 14b. The fixing feature 13a can cooperate with the corresponding fixing feature 14a to fix the article 10 and the electronic device in a releasable manner. In a particular implementation, this is accomplished by magnetic attraction. In addition, the fixing feature 13b can cooperate with the corresponding fixing feature 14b to further fix the article 10 and the electronic device in a releasable manner. In a particular implementation, this is accomplished by magnetic attraction. For example, the fastening features 13a / 14a can be provided in a first location, while the fastening features 13b / 14b can be provided in a second location.
[00075] In a specific example, the fastening feature 14a may, in cooperation with the fastening feature 13a, secure the electronic device 12 to article 10. In another example, the fastening resource 13b can secure article 10 to the electronic device. 12 using the fixing feature 14b. It should be noted that the fixing systems 13 and 14 in this example can be separated or they can cooperate together to produce the fixation. If they cooperate, fixation features 14a and 14b match or match one or more fixation features 13a and 13b. In any case, the fixation features in any of these examples can be realized through mechanical, static, suction, magnetic and / or similar fixation.
[00076] The placement of fastening systems and fastening resources within fastening systems can vary widely. In relation to the electronic device 12, the fixing system 14 can be placed in front, behind, above, below, and / or on the sides. The fixing features 14a and 14b can be placed anywhere within the fixing system 14. Correspondingly, the fixing features 14a and 14b can be placed anywhere in relation to the housing and / or the screen. In one example, the fastening features 14a and 14b can provide a latch along one or more sides of the housing (for example, top, bottom, left, right). In another example, the fastening features 14a and 14b can provide a latch behind the electronic device 12. In yet another example, the fastening features 14a and 14b can provide a latch in the front (for example, where, if present, a screen is located) of the electronic device 12. In some cases, a combination of fastening features may be located in different regions of the electronic device 12, for example, on the sides and the front. In one embodiment, the clamping system 14 including clamping features 14a and 14b does not disturb the surfaces of the electronic device 12. Similarly, clamping system 13 and, in particular, clamping features 13a and 13b do not disturb the surfaces of the electronic device. surfaces of Article 10.
[00077] According to a modality, the fixing features can include magnetic elements. The magnetic elements can be configured to assist in positioning the article 10 in relation to the electronic device 12 in a matching arrangement. The magnetic elements can also help to attach the article 10 and the electronic device 12 to a wedding hitch. It should be noted that the engagement of article 10 and electronic device 12 can be reversed by applying an appropriate release force that allows article 10 and electronic device 12 to separate into individual objects. However, the magnetic elements may allow the article 10 and the electronic device 12 to subsequently resume the wedding engagement without the need for fastening elements of any kind, mechanical, or any other. In this way, the magnetic elements provide a repeatable and consistent engagement between the article 10 and the electronic device 12.
[00078] Article 10 and electronic device 12 may also include components 16 and 18, respectively. Components 16 and 18 typically depend on the configuration of article 10 and electronic device 12 and can, for example, be mechanical or structural components used to provide support or they can be operational / functional components that can provide a specific set of operations / functions . The components can be dedicated to their respective devices or they can be configured to match the aspects of the corresponding item or device (for example, wired or wireless). Examples of structural components may include frames, walls, fasteners, reinforcers, movement mechanisms (articulation), etc. Examples of operational components can include processors, memory, batteries, antennas, circuits, sensors, screens, inputs, and so on. Depending on your desired configuration, the components can be external (that is, exposed on the surface) and / or internal (for example, embedded within the enclosure).
[00079] Figures 2A and 2B are simplified perspective views of article 20 that can be releasably attached to electronic device 22 through a magnetic fixation system, according to a described modality. Article 20 and electronic device 22 can correspond, in general, to those discussed in relation to Figure 1. In one embodiment, the magnetic fixing system can be incorporated as a magnetic surface 24 (shown by dotted lines or shading) and, more in particular, as a magnetic surface 24 on the sides of the electronic device 22. The magnetic surface 24 can provide a magnetic field that can cooperate with a corresponding fixation feature in article 20 when located in proximity to each other. The magnetic field can establish a net magnetic attractive force that can place the article 20 and the electronic device 22 together in marriage engagement along the engagement surface 26 as shown in Figure 2B.
[00080] In other words, the magnetic field provided by the magnetic surface 24 can have properties such that the net magnetic attractive force between the article 20 and the electronic device 22 is substantially perpendicular to the engaging surface 26. Furthermore, the magnetic field can result in the net magnetic attractive force between the article 20 and the electronic device 22 being applied uniformly across the coupling surface 26. In order to release the article 20 and the electronic device 22, a release force can be applied to both objects joined in order to overcome an attractive net magnetic force provided by the magnetic fixing system.
[00081] It should also be assessed that although only one side wall is shown, in some cases, different side walls and possibly a combination of side walls can be used depending on the needs of the fixing interface. It should be noted that the use of magnetic fastening excludes the need for mechanical fasteners, such as fasteners. Furthermore, the lack of mechanical fixations and uniformity of the general magnetic attractive force can leave the surfaces of the article 20 and the electronic device 22 undisturbed, helping to create an appearance of union in which the article 20 and the electronic device 22 may appear as a single entity unified. Uniformity in appearance can enhance the general static appeal of both Article 20 and the electronic device 22.
[00082] In one embodiment, a magnetic surface can be created by embedding magnetically attractive elements in the form of a magnetic fastening feature within the side walls of the electronic device 22 and / or article 20. That is, the magnetically attractive elements they can be arranged within the article 20 and the electronic device 22 such as, for example, within the housing of the electronic device 22. In this configuration, the housing can be formed of a non-magnetic material, such as plastic or non-ferrous metal, such as like aluminum. In this way, the magnetic force lines can be configured to work through the walls of the enclosure. The magnetic fastening features do not disturb the physical appearance of the external surfaces of the article 20 and the electronic device 22. The magnetically attractive elements in the article 20 and the electronic device 22 can be arranged to produce magnetic fields that can cooperate with each other to generate a force magnetic attraction that fixes the article 20 and the electronic device 22 together in the wedding coupling. The magnetic attractive force is configured to generate a magnetic attraction force normal to the engaging surface 26 between the electronic device 22 and the article 20.
[00083] The magnetic attractive force between the corresponding magnetic elements in article 20 and the electronic device 22 can also be applied uniformly along the coupling surface 26. The uniformity of the general magnetic attractive force along the coupling surface 26 can be a result of the uniformity of the separation distance between the corresponding magnetic elements in article 20 and the electronic device 22. The uniformity can also be a result of the consistency of the magnetic flux density between the corresponding magnetic elements in article 20 and the electronic device 22. uniformity of the liquid magnetic fixation can be facilitated by the surfaces of the article 20 and the electronic device 22 forming a well-matched fit. For example, one surface may be flat or have a concave geometry, while the other surface may have a convex shape of correspondence. In this way, by fitting tightly together, a separation distance between each of the corresponding magnetic elements in article 20 and the electronic device 22 can be reduced to a minimum. The conformity of the surface shapes can also enhance the overall look and feel of the article 20 and the electronic device 22 by reducing or eliminating the appearance of a splice on the engagement surface 26. This seamless quality can provide an illusion of a single entity when article 20 and electronic device 22 are attached to each other.
[00084] In addition to enhancing the overall look and feel, the consistency of the separation distance between the magnetic elements can produce a clamping force between the article 20 and the electronic device 22 evenly across the engagement surface 26. In this way, the coupling force can be evenly distributed across the coupling surface 26, avoiding arching, weak points, and so on, which may adversely affect the overall integrity of the coupling between the article 20 and the electronic device 22.
[00085] Figures 3A and 3B are seen in simplified perspective of article 20 which can take the form of an electronic device 30 which can be fixed directly and releasably to the electronic device 32 through a magnetic fixation system according to a described mode. In one embodiment, the magnetic fastening system can be incorporated as the magnetic surface 34 (shown by dotted lines or shading) and, more particularly, as the magnetic surface 34 on the sides of the electronic device 32. The magnetic surface 34 can provide a field magnetic device that can cooperate with a corresponding fixing feature on the electronic device 30 when placed in proximity to each other. The magnetic field can establish a net magnetic attractive force that can place the electronic device 30 and the electronic device 32 together in marriage engagement along the engagement surface 36 to form a cooperating system 38, as shown in Figure 3B.
[00086] Figures 4A and 4B are simplified perspective views of article 40 which can be releasably attached to electronic device 42 through magnetic fixation unit 44 and the corresponding magnetic system 46. It should be noted that this particular modality is similar to the modality described in Figures 2A, 2B except that the magnetic clamping unit 44 is used to magnetically clamp the article 40 and the electronic device 42 which were previously clamped together directly on their respective side walls. In this way, the fixation system 46 can include a plurality of magnetic fixation features arranged to provide a suitable magnetic fixation to article 40 and electronic device 42, respectively.
[00087] Figure 4B shows the article 40 and the electronic device 42 magnetically attached to each other by means of the magnetic clamping unit 44 on the engaging surfaces 47a and 47b to form the cooperation system 48. As part of the system 48, the device electronic 42 and article 40 may cooperate with each other to provide resources not available under article 40 or electronic device 42 separately. For example, article 40 may take the form of a hanging device, an anchoring device, a mounting device, and so on, which can provide resources to a user not available by electronic device 42 separately. In one embodiment, article 40 may take the form of an anchoring system that can be magnetically attached to the electronic device 42 by means of the magnetic clamping unit 44. In one embodiment, the anchoring system can provide mechanical support to the electronic device. 42. In one embodiment, the docking system can act to provide information to the electronic device 42. In one embodiment, the information can be stored within a storage device embedded in the magnetic clamping unit 44. In one embodiment, the information can be be received in article 40 (via a WiFi connection, for example) and passed through a magnetic fixing unit 44 to the electronic device 42, and vice versa.
[00088] In one embodiment, article 40 can be used to hang electronic device 42. For example, article 40 can include hooks, fasteners, and so on, which can be used to grab another object for support. Article 40 can be used to provide support for electronic device 42. For example, article 40 can take the form of a hinge bracket that can be magnetically attached to electronic device 42. The articulation nature of article 40 can be used to present the electronic device 42 in various angles and orientations. It should be noted that due to the releasable nature of the magnetic fastening between the magnetic fastening unit 44 and the article 40, it can be easily separated when the electronic device 42 is used and subsequently refixed when desired.
[00089] Figures 5A and 5B are seen in simplified perspective of article 40 in the form of electronic device 50 which can be releasably attached to an electronic device 52 via magnetic fixation unit 54. This modality is similar to that shown in Figures 4A and 4B in that the magnetic clamping unit 54 may include multiple magnetically attractive elements. For example, the magnetic elements can be placed inside the magnetic fastening unit 54 in order to create magnetic surfaces 56a and 56b suitable for activating the magnetic fastening systems in electronic devices 50 and 52, respectively. For example, activation of the magnetic clamping system on the electronic device 52 can result in the magnetic surface 58 being displayed on the side wall of the electronic device 52. The magnetic surface 58 can be used to magnetically clamp the magnetic clamping unit 54 and the electronic device. 52 on the engaging surface 60a. In one embodiment, the magnetic surface 56b can be created on an opposite side wall of the magnetic fixing unit 54. Similar to the electronic device 54, the magnetic surface 56b can be used to activate a magnetic fixing system on the electronic device 50 that creates a magnetic surface suitable for magnetically attaching the magnetic fixing unit 54 to the electronic device 50 on the engaging surface 60b creating a cooperation system 62 shown in Figure 5B.
[00090] However, it should be noted that although the magnetic attachment side by side between the electronic devices 50 and 52 is shown, in some embodiments, the magnetic surfaces may be located on the lower surfaces and / or upper surfaces of the electronic devices 50 and 52. For example, the magnetic elements of the magnetic clamping unit 54 can be embedded behind the upper surface 64 of the magnetic clamping unit 54 creating a magnetic surface 66 for attachment to the rear surfaces of electronic devices 50 or 52 forming a back arrangement. to each other. It should be noted that although not shown, additional magnetic elements can be embedded in a lower surface of the magnetic fixation unit 54.
[00091] Figure 5B shows the electronic device 50 and the electronic device 52 magnetically fixed together to form a cooperation system 62. In this arrangement, the electronic device 52 and the electronic device 50 can cooperate with each other to provide resources not available by electronic device 50 or electronic device 52 separately. For example, electronic device 50 can receive information in the form of, for example, an input command from a user and / or input data from, for example, a sensor. The electronic device 50 can process the information in whole or in part and pass the processed information to the electronic device 52 for further processing, in this way, the cooperation system 62 can process the information more efficiently while preserving the computational resources that provide a user experience. improved user experience compared to that expected from the 50 or 52 electronic device acting separately.
[00092] The cooperation system 62 can be formed by placing the magnetic fixture unit 54 and the electronic devices 50 and 52 in proximity to each other so that the magnetic surfaces 56a and 56b on the sides of the magnetic fixation unit 54 activate the magnetic fastening systems on electronic devices 52 and 50, respectively. In turn, the activated magnetic systems provide magnetic surfaces (such as the magnetic surface 58) that interact with the magnetic clamping unit 54 to create a net magnetic attractive force of sufficient magnitude and direction to hold the electronic device 50 and the electronic device 52 in a marriage hitch to form the cooperation system 62.
[00093] In one embodiment, the magnetic clamping unit 54 can be formed of a rigid material. In one embodiment, the magnetic clamping unit 54 can be foldable. In one aspect, the foldable nature of the magnetic clamping unit 54 can be used to provide a user with a user interface, such as a keyboard and a screen that can be presented as a visually comfortable angle, such as 75 °.
[00094] Although the purpose of the magnetic elements is similar, that is, to fix the article to the electronic device, to fix the electronic device to the electronic device, it must be evaluated that these mechanisms can vary widely. In some cases, magnetic fields can be configured differently. As an example, the side-mounted magnetic surface can provide a first magnetic force and the forward-facing magnetic surface can provide a second magnetic force that is different from the first magnetic force. This may partly occur due to different retention requirements, as well as different surface areas, that is, available space, and its effect on the internal components of the electronic device. In one example, the side-mounted magnetic surface provides a greater holding force for attaching the article (or electronic device) to the electronic device (ie, the primary clamping force) while the forward facing magnetic surface is the clamping force secondary.
[00095] In one example, the magnetic clamping unit 54 includes multiple sections that are semi-rigid and fold in relation to each other in order to make the magnetic clamping unit mobile and flexible. In one embodiment, the magnetic clamping unit 54 can be folded into one or more different configurations, and, in some cases, can be maintained in these configurations using a magnetic system similar to that described above. These and other modalities will be described in more detail later. In addition, it should be noted that the modalities described are not limited to those specifically described and other configurations can be used, including, for example, an accessory device used as a hanging device, as a support mechanism for the electronic device to improve visualization. of the screen and as a support mechanism for inserting touch events into a touch sensitive portion of the screen, and so on.
[00096] The electronic device and the article can take many forms. For the remainder of this discussion, the electronic device is described in terms of a portable, handheld computing device. Correspondingly, Figure 6 shows a top perspective view of the electronic device 100 according to the described modalities. Electronic device 100 can process data and, more particularly, media data, such as audio, visual, image data, etc. As an example, electronic device 100 can generally correspond to a device that can function as a smartphone, a music player, a game player, a visual player, a personal digital assistant (PDA), a tablet-like computer, and similar. Electronic device 100 can also be hand held. In relation to being hand held, electronic device 100 can be held in one hand while being operated by the other hand (i.e., no reference surface, such as a desktop, is required). Therefore, the electronic device 100 can be held in one hand while operational input commands can be provided by the other hand. Operational input commands may include operating a volume switch, a lock switch, or providing inputs to a touch sensitive surface, such as a touch screen device or a touch pad.
[00097] Electronic device 100 may include housing 102. In some embodiments, housing 102 may take the form of a one-piece housing of any number of materials, such as plastic or non-magnetic metal that can be forged, molded, or , otherwise, formed in a desired format. In those cases where the electronic device 100 has a metallic housing and incorporates a radio frequency (RF) based functionality, a portion of the housing 102 may include radio-transparent materials, such as ceramic, or plastic. Housing 102 can be configured to contain a number of internal components. For example, housing 102 can confine and support various structural and electrical components (including integrated circuit chips) to provide computational operations for electronic device 100. Integrated circuits can take the form of chips, chip sets, or modules, with any of these can be surface mounted to a printed circuit board, or PCB, or other support structure. For example, a main logic board (MLB) can have integrated circuits mounted on it that can include at least one microprocessor, a semiconductor memory (such as FLASH), and several support circuits, and so on. Enclosure 102 can include an opening 104 for placing internal components and, as needed, can be sized to accommodate a display assembly to present visual content, the display assembly being coated and protected by a protective layer 106. In in some cases, the display assembly can be touch sensitive, allowing tactile inputs that can be used to provide control signals to the electronic device 100. In some cases, the display assembly can be a large prominent display area that covers most of the area in front of the electronic device.
[00098] Electronic device 100 may include a magnetic clamping system that can be used to magnetically clamp electronic device 100 to at least one other properly configured object.
[00099] The magnetic fastening system may include a series of distributed magnetic fastening features and, in some cases, connected to housing 102. For example, the magnetic fastening system may include a first magnetic fastening feature located in close proximity to the wall side 102a and a second magnetic clamping feature located below the glass cover 106. In one embodiment, the first magnetic clamping feature can operate in multiple states. For example, in an inactive state, the first magnetic fastening feature can provide a first magnetic surface M1 on an external surface of the sidewall 102a. The first magnetic surface M1 can represent a magnetic field having little or no effect on magnetically sensitive devices placed on the outer surface of the side wall 102a and is also not suitable for magnetic fixation. In other words, the magnetic surface M1 is consistent with the magnetic flux density B on the side wall 102 which satisfies Equation (1): B - Bthreshold Equation (1) where Bthreshold represents a magnetic flux density value B corresponding to a value leakage of magnetic flux on the side wall 102a that does not facilitate magnetic fixing on the side wall 102a and does not substantially affect a magnetically sensitive device on the side wall 102a.
[000100] In an active state, however, the first magnetic fastening feature can provide a second magnetic surface M2 on the outer surface of the sidewall 102 as shown in Figure 6B in crosshatching. The magnetic surface M2 is consistent with the magnetic facilitation fixation on the external surface of the sidewall 102 that satisfies Equation (2): B> Bthreshold Equation (2).
[000101] In one embodiment, an external magnetic field having appropriate magnetic properties can cause the first magnetic fixation system to transition from the inactive state to the active state. In this way, the magnetic surface expressed on the side wall 102a can change from the magnetic surface M1 (shown in Figure 6A) to the magnetic surface M2 (shown in Figure 6B). The external magnetic field can be provided by a magnetic clamping feature external to the electronic device 100 that cooperates with the first magnetic clamping feature causing the operational state of the first magnetic clamping feature to change from inactive to active.
[000102] The second magnetic fixation feature can assist in the magnetic fixing of another device to the electronic device 100, providing an M3 magnetic surface that satisfies Equation (2). In one embodiment, the second magnetic clamping feature operates in an operational state consistent with the magnetic supply surface M3.
[000103] Although not expressly shown, it is understood that the various magnetic fastening features of the magnetic fastening system can be located at any appropriate location in the housing 102. For example, the magnetic fastening features can be located on an inner bottom surface of housing 102 or along sides 102c and 102d of housing 102.
[000104] As shown in Figures 7A-7B and with reference to the previous discussion in relation to Figures 5A-5B, the magnetic clamping unit 54 can be used to magnetically clamp electronic devices 100 and 120 to form a cooperation system 130 in the engagement surfaces 132a and 132b. The co-operation system 130 can utilize resources from both electronic devices 100 and 120 alone or in combination. In one embodiment, electronic device 100 may have a virtual keyboard that can respond to a touch event by remotely sending information corresponding to electronic device 120. Electronic device 120 can use the information to provide an answer. For example, a user can select from a list of icons displayed by the electronic device 100 a particular media item, or items. An identification of the selected media item (s) can be forwarded (either remotely or via a cable connection) to the electronic device 120. In one embodiment, the electronic device 120 can decode and display at least a portion of the selected media item.
[000105] Figures 8A-8C show various modalities of the magnetic clamping unit 200 that can be used to magnetically clamp the electronic device 100 to an object having a suitably configured magnetic clamping system. The object can take the form of an accessory device. The object can take the form of an electronic device. In some cases, the accessory device may include electronic components that can communicate with the electronic device 100, and vice versa. In any case, the magnetic clamping unit 200 may include magnetic clamping features 202 and 204 connected together by means of a flexible member 206. In one embodiment, the magnetic clamping features 202 and 204 can be fixedly attached to the flexible member 206. In one embodiment, the magnetic clamping features 202 and 204 can be pivotally connected to the flexible member 206, thereby providing additional degrees of freedom for the magnetic clamping unit 200.
[000106] Figure 8A shows a lateral cross-sectional view of the magnetic fastening resources 202 and 204 according to the described modalities. In this particular illustration, the magnetic fastening features 202 and 204 are magnetically attached to a portion of the housing 102 having a substantially flat surface. However, it should be noted that housing 102 may have a curved shape, in which case the shape of several components of the magnetic fastening features 202 and 204 described below may take on a shape that conforms to the shape of housing 102. In this way, a separation distance between the corresponding magnetic elements within the housing 102 and the magnetic clamping features 202 and 204 can be minimized, thereby maximizing a net magnetic attractive force.
[000107] It should be noted that in the previous description, the magnetic fastening features 202 and 204 have substantially the same configuration. However, in some embodiments, the magnetic fastening features 202 and 204 may differ in some way in structure depending on the nature and shape of the objects being magnetically fixed to each other. Therefore, as a summary, only the 202 magnetic fixation feature will be described.
[000108] The magnetic elements in the electronic device 100 can interact magnetically with the corresponding magnetic element 204. In one embodiment, the magnetic element 208 can have a thickness of about 2 mm and have a shape that substantially conforms to that of the housing 102. The magnetic interaction between the magnetic element 208 and those magnetic elements in the electronic device 100 can create an attractive net magnetic force consistent with a separation distance xsep equal to about the total thickness t of the housing 102 and the thickness "l" of the label 210 The thickness “l” can be in the order of about 0.2 mm. Tag 210 can be used to protect the outer surface of housing 102 from possible scratches and other cosmetic damage potentially caused by metal-to-metal contact between magnetic element 208 and housing 102. Both tag 210 and magnetic element 208 can be shaped to conform to the shape of the housing 102. In this way, the distance between the magnetic element 208 and the magnetic element in the electronic device 100 can be reduced to about the thickness t of the housing 102 and the thickness l of the label 210.
[000109] Magnetic tap 212 can be glued and confined to such a portion of magnetic element 208 facing away from housing 102. Magnetic tap 212 can be formed of a magnetically active material, such as steel or iron. The magnetically active material can redirect magnetic flow lines that would otherwise be directed away from the magnetic elements in the electronic device 100 towards housing 102, thereby increasing the total magnetic flux density B between the magnetic clamping feature 202 and the electronic device 100. The magnetic tap 212 can be successively glued to the housing 214 of the magnetic clamping feature 202. It should be noted that in order to ensure that only the label 210 contacts the housing 214 ( to avoid metal-to-metal contact), label 210 is assumed (that is, protrudes) from housing 102 over a distance "d". Nominally, the distance d can be in the order of about 0.1 mm.
[000110] Figure 8B shows a modality of the magnetic fixing feature 200 where the magnetic fixing features 202 and 204 are coupled to the rigid member 216. As noted earlier, the magnetic fixing features 202 and 204 can be fixedly connected to the rigid member 216. In one embodiment, the magnetic fastening features 202 and 204 can be pivotally connected to the rigid member 216.
[000111] Figure 8C shows another embodiment of the magnetic clamping unit in the form of a magnetic clamping unit 220 where the magnetic clamping features 202 and 204 are incorporated within the connecting member 222 (which can be rigid or flexible). In this configuration, there is no need for a housing 214. Therefore, only magnetic element 208, tag 210, and derivative 212 are required.
[000112] The remainder of this discussion will describe particular types of devices that can use the magnetic fixation system. In particular, electronic device 100 will now be described in terms of a tablet-like computing device, such as the iPad ™ manufactured by Apple Inc. of Cupertino, CA, USA.
[000113] In one embodiment, accessory device 120 can be used to enhance the general functionality of electronic device 100. For example, accessory device 120 can be configured to act as a hanging device. When magnetically attached to electronic device 100, accessory device 120 can be used to hang electronic device 100. In this way, electronic device 100 can be used as a screen to display visual content, such as art, films, photos, and so on. onwards, on a wall or suspended from a ceiling. As a hanging device, accessory device 120 can be used to hang an electronic device 100 from a wall or ceiling. The electronic device 100 can be easily removed by simply exerting sufficient release force to overcome the net magnetic attractive force FNET. Accessory device 120 can be left in position and used to reseat electronic device 100 (or another device) at a later time.
[000114] In one embodiment, accessory device 120 can also take the form of a retention mechanism that serves to attach objects that are not equipped to attach magnetically to electronic device 100. For example, accessory device 120 can be configured to carry a stylus or other input device. The stylus can be used to provide inputs to the electronic device. In some cases, accessory device 120 may provide a signal to electronic device 100 indicating the presence of the stylus. The signal can cause the electronic device 100 to enter a stylus recognition state, for example. More particularly, when accessory device 120 is magnetically attached to electronic device 100, electronic device 100 can activate a stylus input state in order to recognize stylus inputs. When accessory device 120 is removed, electronic device 100 can disable the stylus input state. In this way, the stylus can be conveniently attached / detached to the electronic device 100 when necessary.
[000115] Accessory device 120 can take the form of a holder that can be used to enhance the functionality of electronic device 100. For example, accessory device 120 can be configured to act as a display platform on which a display device electronic 100 can be viewed at a comfortable viewing angle, such as 75 °. In other words, when placed on a horizontal surface, such as a table or desk, accessory device 120 can support electronic device 100 so that the visual content displayed on the screen can be viewed around a viewing angle of approximately 75 °.
[000116] Accessory device 120 may also take the form of a holder that can be used to enhance the functionality of electronic device 100 in a keyboard state. In the keyboard state, accessory device 120 can be used to present a touch sensitive pad surface at an angle that is ergonomically friendly. In this way, the incoming touch events can be applied (to a virtual keyboard, for example) at an angle that does not require too much of the wrist, hands, arms, etc. of a user.
[000117] Figure 9 illustrates an arrangement 300 formed by magnetically attaching a tablet-like device 302 and a tablet-like device 304 by means of a flexible magnetic clamping unit 306 in an open configuration. The magnetic clamping unit 306 may include a flexible connecting member 308 arranged to connect pivotal hinge assemblies 310 and 312 to each other, each of which are magnetically connected to tablet devices 304 and 302, respectively. The hinge assemblies can provide one or more pivots to allow the magnetic clamping unit 306 to bend, while the magnetic clamping unit 306 is magnetically attached to the devices 302 and 304.
[000118] In one embodiment, the hinge assembly 310 may include a first hinge portion (also referred to as first end fin) 314 and a second hinge portion (or second end fin) 316 disposed opposite the first end fin . The first end fin 314 can be rigidly connected to the second end fin 316 by means of a connecting rod (not shown) incorporated into the connecting member 308 providing an additional hinge axis. The connecting rod can be formed of metal or plastic strong enough to rigidly support tablet devices 302 and 304.
[000119] The hinge extension 318 can include magnetic elements. The magnetic elements can be arranged to magnetically attach the hinge extension 318 to a magnetic clamping feature having a matching arrangement of the magnetic elements in the tablet type devices 302 and 304. More specifically, the magnetic elements within the hinge extension 318 can activate a magnetic feature on tablet devices 302 and 304 making them able to attach magnetically to the hinge extension 318. The hinge extension 318 can be formed from a magnetically inactive material, such as plastic or non-magnetic metal, such as aluminum .
[000120] Layout 300 can be referred to as a book in which each tablet-like device 302 and 304 can display visual information in a manner similar to a book. For example, as shown in Figure 9, in the open configuration, the layout 300 can look like an open book in which the screen 320 of the tablet-like device 302 can function as a page in an open book (like the screen 322 on a tablet 304). In one embodiment, a user can “flip” the pages simply by passing a touch-sensitive surface of the tablet-like device 302 (or that of the tablet-like device 304) to flip forward using, for example, a flip gesture from left to right. On the other hand, in order to turn a page (or pages) backwards, the user can swipe a touch-sensitive surface on any tablet-like device 302 or 304 using, for example, a right-to-page gesture left.
[000121] In any case, in the book type mode shown in Figure 9, the tablet type devices 302 and 304 must communicate with each other in order to provide a reasonable approximation of a book and a way in which a book presents information. This communication can take the form of wireless communication between tablet devices 302 and 304.
[000122] Figure 10 shows an arrangement 300 in a closed configuration in which the tablet-like device 302 and 304 uses the flexible nature of the flexible connecting member 306 to bend one on top of the other. In one embodiment, the magnetic elements below screens 320 and 322 can be arranged in such a way as to prevent tablet devices 302 and 304 from touching each other. In one configuration, the magnetic elements can be arranged to interact in such a way as to create a net magnetic repulsion force between the tablet-like device 302 and the tablet-like device 304 avoiding a contact between them. In one embodiment, the magnetic elements can be arranged to create an attractive liquid magnetic force that can lock the tablet-like devices 302 and 304 together. In one embodiment, the magnetic elements can be arranged so as to provide little or no magnetic force in the closed configuration.
[000123] Figures 11A and 11B show tablet devices 302 and 304 magnetically attached to each other by means of a magnetic clamping unit 330. In one embodiment, the magnetic clamping unit 330 may include a connecting member 332 formed of portions rigid 334 and 336 pivotally connected to each other by means of a hinge (or coupling drum) 338. As shown in Figure 11A, the tablet-like device 302 can be placed on a flat support surface, such as a table. The tablet-like device 304 can then be positioned in a vertical orientation relative to the tablet-like device 302. In this way, the tablet-like device 304 can act as a screen for displaying visual content.
[000124] Figure 12A shows tablet-like devices 302 and 304 connected together by means of a magnetic clamping unit 340. As shown, the magnetic clamping unit 340 does not include hinge assemblies 318 and is therefore fixedly attached to the tablet-like devices 302 and 304. The magnetic clamping unit 340 can include rigid connecting members 342 pivotally connected to each other by means of a hitch drum, or hinge, 338. Thus, as shown in Figure 12B, the tablet-like device 302 can be placed on a flat support surface, such as a table and other electronic device (such as the tablet 304) can be positioned to act as a screen. As can be seen in Figures 12B and 12C, the tablet-like device 304 can be replaced by an electronic device 100 that is not necessarily a tablet-like device. For example, the electronic device 100 can take the form of a simple screen capable of being magnetically attached to the magnetic clamping unit 340. In one embodiment, the magnetic clamping unit 340 can actually be formed as part of the electronic device 100. In this way , the magnetic clamping unit 340 may include only a single magnetic clamping feature suitable for magnetically clamping to the tablet-like device 302.
[000125] As shown in Figure 12C, support structure 350 can be used to provide additional support for a raised electronic device, regardless of whether the raised electronic device takes the form of an electronic device 100 or a tablet type 304 device.
[000126] Figure 13 shows a magnetic fixation unit 220 that magnetically fixes tablet-like devices 302 and 304 to form a tablet-like arrangement 360. Correspondingly, tablet-like devices 302 and 304 can communicate with each other via a wireless connection. In one embodiment, the wireless connection can take the form of a wireless WiFi communication where the tablet type devices 302 and 304 communicate with each other directly. In one embodiment, tablet devices 302 and 304 can communicate with each other in part through an external circuit, such as a wireless router, server computer, and so on. In one embodiment, the magnetic clamping unit 220 can provide communication features to assist in communication between tablet devices 302 and 304. In one embodiment, the magnetic clamping unit 220 can include processing as well as data storage features. which can be used to change the operational state or both tablet devices 302 and 304. For example, when the magnetic clamp unit 220 includes a data storage device (such as a FLASH memory), the data on the storage device they can be transferred to one or both tablet devices 302 and 304. The transferred data can take the form of instructions that can be executed to change the operating status of the respective tablet device.
[000127] Figure 14A shows a cross section of the system 400 according to a modality. The system 400 may include a tablet-like device 402 magnetically attached to the cover assembly 404 by means of a magnetic hinge assembly 406. The cover assembly 404 may include a segmented cover 408 pivotably attached to the hinge assembly 404 on pivot 410. A hinge assembly 406 can be magnetically attached to the tablet device 402 by means of a magnetic element 412 in the hinge assembly 404 and a magnetic clamping feature 414 on the tablet type 402. The intervening layer 416 can act to prevent direct contact metal to metal between the hinge assembly 406 and the housing 418 of the tablet-like device 402.
[000128] The cover assembly 404 can also include a separate flap portion 420 pivotally attached to the hinge assembly 406 on pivot 422. In this way, the segmented cover 408 and the flap portion 420 can be rotated around their respective pivots separately as shown in Figure 14B where the segmented cover 408 has been folded onto the support structure 424. The support structure 424 can be triangular in shape and used to position the tablet-like device 402 so that the screen 426 is presented around an angle of 75 °.
[000129] The flap portion 420 may be formed of a flexible material, such as fabric. In one embodiment, the flap portion 420 may include several input devices. For example, as shown in Figure 15, the flap portion 420 may include a keyboard 430. The keyboard 430 may be in communication with the tablet type device 402 using, for example, a wired connection. In one embodiment, the keyboard 430 can be in wireless communication with the tablet-like device 402. Correspondingly, a user can pass information to the tablet-like device 402 by pressing several input keys on a 430 fabric keyboard.
[000130] It should be noted that the flap portion 420 can be configured to include any suitable type of input device. For example, in an embodiment shown in Figure 16, the flap portion 420 can take the form of an input pad 440. The input pad 440 can be sensitive to touch events, such as those provided by a stylus, stylus , pencil, or even a part of the human body, like a finger. Still as shown in Figure 17, the flap portion 420 may include a touch pad 450 that can be used to provide information to the tablet type device 402 by user touching the touch pad 450 in a prescribed manner.
[000131] Figures 18A-18D show a magnetic docking station 500 according to the described modalities. The magnetic docking station 500 may include a support 502 and a base portion 504. The base portion 504 may include the magnetic elements 506 arranged to activate a magnetic fastening feature on the electronic device 100. Therefore, placing the electronic device 100 in a slot 508 of the base portion 504 can result in magnetic elements 506 activating the magnetic fastening feature on the electronic device 100. Activation can cause a net attractive magnetic force between the magnetic elements 506 E The electronic device 100 is strong enough to attach the electronic device 100 to the docking station 500. In an embodiment shown in Figure 17B, the electronic device 100 can take the form of a tablet-like device 302. In one embodiment, the docking station 500 can supply electrical power to the electronic device 100. In one embodiment, the docking station 500 and the electronic device 100 can communicate with each other by rowing via an appropriate wireless communication protocol, such as WiFi, BlueTooth, and so on. In one embodiment, the docking station 500 may include docking port (s) that provide a wired communication channel between the electronic device 100 and another electronic device connected to the docking station 500 or, in some cases, a device input, such as a keyboard, a numeric keypad, a touch pad, etc. In the embodiment shown in Figures 18A-18D, the docking station 500 is attached to such an electronic device 100 shown at a substantially fixed angle and orientation with respect to a support surface, such as a table or desk on which a input, such as a keyboard, may be located.
[000132] However, as shown in Figures 19A, the docking station 600 can be hinged around pivot point 602. In this way, the electronic device 100 can be presented at a series of angles in relation to the support surface. The pivot docking station 600 can include a base portion 604 pivotally connected by means of a pivot 602 to the support 606. In one embodiment, the magnetic elements 610 can activate a magnetic clamping feature 612 in the electronic device 100 to magnetically couple the electronic device 100 to the hinge docking station 600. In one embodiment, the magnetic elements 610 can be included in the base portion 604. Figure 19B shows a mode where the electronic device 100 takes the form of a tablet-like device 302. A Figure 19C shows an articulation docking station 650 according to an embodiment of the invention.
[000133] Figures 20A-20D show various hanging accessories 700 that can be magnetically attached to the tablet-like device 302 according to the described modalities. It should be noted that as shown, the hanging accessories are formed to include the magnetic elements arranged to activate the magnetic fastening feature included with the 302 tablet device. This integrated arrangement can reduce the number of components required. In one embodiment, however, the hanging accessories can be magnetically attached to the tablet-like device 302 using the magnetic attachment unit described above. In any case, the various hanging accessories can be used to hang or otherwise suspend the tablet-like device 302 from any suitable surface. For example, Figures 20A and 20B show variations of the hanging accessory 700 well suited for suspending the tablet-like device 302 from a vertical wall. For example, the hook attachment 702 and the suction cup attachment 704 can be used to hang the tablet-like device 302 from a vertical wall, such as in an office stall in the case of a hook attachment 702 and a refrigerator door, blackboard, or bulletin board in the case of a suction cup accessory 704 shown in Figure 20B.
[000134] Figures 20C and 20D show modalities of a hanging accessory 700 that can allow a user to carry a tablet-like device 302. For example, the fixed-handle accessory 706 can facilitate a user to hold the tablet-like device 302 securely in one hand while the 708 strap attachment can allow the user to carry the 302 tablet device more fluidly.
[000135] Figures 20E and 20F show a hanging accessory modality 700 that can be used to hang an electronic device 100 from a vertical surface unsuitable for hooks or other pickup accessories. These surfaces include bulletin boards, blackboards, smooth metal surfaces, wooden surfaces, and so on. Correspondingly, the hanging accessory 710 may include a support 712 to which suction cups 714 (or equivalent) are attached which can be used to removably adhere the hanging accessory 710 to said front surfaces. The hanging accessory 710 also includes a base portion 716 that includes the magnetic elements 718 used to activate the magnetic fastening feature 720 on the electronic device 100. Figure 20E shows a modality in which the electronic device 100 takes the form of a device tablet type 302 attached to a 722 notice board.
[000136] Figures 21A-21B show additional modalities of the hanging accessory 700 that can extend the utility and range of applications to which the tablet-like device 302 can be used. For example, Figure 21A shows a tablet-like device 302 mounted to an automobile headrest, for example, using a lock 712 that conforms to the shape of the headrest. In some embodiments, the closure 712 may be somewhat flexible in order to accommodate a variety of shapes and sizes of headrests. In another example, Figure 21B shows the lock 714 that can be used to hang the tablet-like device 302 from an aircraft seat, for example, it should be noted that in both cases, the tablet-like device 302 can be magnetically attached to both locks 712 and 714 by means of magnetic elements embedded in the base portions 716 and 718, respectively. In one embodiment, the base portions 716 and 718 can be pivotally connected to the locks 712 and 714 in order to provide the viewer with an adjustable viewing angle.
[000137] In addition to hanging, or otherwise assembling, as shown in Figure 22A, the tablet-like device 302, the mounting accessory 720 can be used to mount the tablet-like device directly to an automobile dashboard, for example . In one embodiment, mounting accessory 720 can be attached to panel 724 and can include magnetic elements that can be used to activate the magnetic fastening feature included with the tablet-like device 302. In addition to mechanically attaching the tablet-like device 302 to the panel, mounting accessory 720 can be used to transport power to the tablet-like device 302, provide a connection to other electronic devices within the vehicle, and so on. For example, when the tablet-like device 302 can remotely transmit audio and, in some cases, video data to an appropriate receiving circuit. In this way, the media data can be transported from the tablet-like device 302. In one embodiment, the tablet-like device 302 can be used in conjunction with other electronic services available to the vehicle. For example, GPS-based navigation can be displayed on the 302 tablet device, traffic alerts can be posted, vehicle information (fuel level, charge level, etc.) can be posted, and so on. In one embodiment, user input can be provided to the 302 tablet device. User input can be used to change a vehicle's opening characteristic, media, and so on. Figure 22B shows a mounting accessory 720 that can be used to mount the tablet-like device 302 to exercise equipment, such as a 722 mat.
[000138] Figures 23A-23H show the modalities of the tablet-like device 302 magnetically attached to various peripheral devices 800. For example, Figure 23A shows an 802 camera magnetically attached to the tablet-like device 302. The camera 802 can operate together or separately from the image capture features included with the tablet-like device 302. Figure 23B shows a stylus holder 804 with a stylus pen 806. In one embodiment, the operation of the tablet-like device 302 can be switched to a recognition mode. stylus when it detects the stylus holder 804 (or the presence of the stylus 806). In the stylus recognition mode, the operation of the tablet type device 302 can be such that the movements of the stylus pen 806 on the screen 808 can be recognized and influenced by the tablet type device 302.
[000139] Figure 23C shows a card reader 810 magnetically attached to the tablet-like device 302. In this arrangement, a user can swipe a magnetically encoded card, for example, and the information becomes readily available for processing by the tablet-like device 302. Figure 23D shows an RF 812 antenna mount that can be used to supplement RF reception and transmission from the tablet-like device 302.
[000140] Figure 23E shows a memory module 814 magnetically attached to the tablet type device 302 arranged to provide additional memory resources to the tablet type device 302. Figure 23F shows a keyboard 816 magnetically attached to the tablet type device 302. The keyboard 816 it can communicate with the tablet-like device 302 remotely or over a wired connection.
[000141] Figure 23G shows a game controller 818 magnetically connected to the tablet-like device 302. In one embodiment, the game controller 818 can provide information to the tablet-like device 302. The information may include the game to be played, historical information information, player identification and information, and so on. Figure 23H shows an audio output module 820 having speakers 822 for broadcasting audio content provided by the tablet-like device 302.
[000142] Figure 24 shows a travel folder 900 that can be used to store and transport a tablet-like device 902. The travel folder 900 can include magnetic elements 904 arranged to activate the magnetic fastening feature 906 on the tablet-like device 902 In one embodiment, the travel folder 900 may have a shell-like arrangement whereby the cover 908 can, in a closed configuration, confine the tablet-like device 902 within a cavity formed by the cover 908 and the base 910. In In one embodiment, the tablet-like device 902 can be manually released by grasping and removing the tablet-like device 902. In one embodiment, the travel folder 900 may include a release mechanism that can overcome the magnetic attraction between the magnetic elements 904 and the magnetic fastening feature 906 on the tablet-like device 902. In one embodiment, the release mechanism may be mechanical in nature. In one embodiment, the release mechanism can be electromechanical in nature, in which an electromagnetic element in the travel paste 900 can be energized to overcome the magnetic attraction between the magnetic elements 904 and the magnetic fastening feature 906.
[000143] Figures 25A and 25B show the representative magnetic attraction between the magnetic elements 920 in the object 922 and the magnetic clamping feature 924 in an electronic device that can take the form of a tablet-like device 926. As shown in Figure 25A, the magnetic elements 920 may include at least one electromagnetic element that can be used to provide an electromotive force. The electromotive force can be used to overcome the net magnetic attractive force Fnet between the magnetic elements 920 and the magnetic clamping feature 922. The electromotive force can cause the object 922 to separate from the electronic device without the use of hands or another mechanical mechanism. The electromagnetic element can be remotely activated or can be activated using the electronic device. For example, when the electronic device takes the form of the 930 tablet type device, a home button 932 can be pressed, thus causing the activation of the electromagnetic element resulting in the magnetic attraction between the magnetic clamping feature 922 and the magnetic elements 920 being overcome by allowing the 930 tablet device to be removed from the 900 travel folder.
[000144] Figures 26A-26C graphically illustrate a mechanism whereby a magnetically sensitive circuit, such as a Hall effect sensor, can be used to change an operational state of an electronic device. In particular, Figure 26A shows a tablet-like device 1000 in an OFF operating state. The tablet-like device 1000 may include a magnetically sensitive circuit, such as a Hall effect sensor 1002. In one embodiment, the tablet-like device 1000 may also include a light-sensitive device 1004. In one embodiment, the light-sensitive device 1004 it can take the form of an ambient light sensor (ALS). In one embodiment, the light sensitive device 1004 can take the form of an image capture device, such as a camera. It should be noted that the light sensitive device 1004 can also take the form of any combination of built-in devices that, for example, a sensor board that can include both an ambient light sensor and a camera can operate independently or in cooperation between itself.
[000145] In one embodiment, an operational state of the tablet-type device 1000 can be changed by an external magnetic field H. In one embodiment, the external magnetic field H can be transient in nature, which means that the external magnetic field H may vary in time and / or in magnetic field resistance. In one situation, the external magnetic field H can be generated by a magnetic element, such as a magnetic ring 1006, which generates a substantially non-transient magnetic field that is, however, transient as perceived by the magnetically sensitive device 1002. For example, by moving the magnetic ring 1006 from left to right as shown in Figures 26A-26C, the Hall effect sensor 1002 can detect the external magnetic field H as being transient in nature where the resistance of the external magnetic field H starts at a value initial and increases in value as the magnetic ring 1006 approaches a Hall effect sensor 1002 and then decreases again as the magnetic ring 1006 moves away from the Hall effect sensor 1002. Field detection transient external magnetic H provided by the movement of the magnetic ring 1006 can result in a Hall effect sensor 1006 providing a signal to the tablet type device 1000. The signal can be interpreted by the tablet type device 1000 to change from a current operating state (such as OFF) to another operating state (such as ON) as shown in Figure 26C. In one embodiment, the change in state of the tablet-type device 1000 can be binary pro-nature due to the fact that by passing ring 1006 through the Hall effect sensor 1002 a second time, the signal provided by the Hall effect sensor 1002 can be interpreted by the tablet device 1000 to change the current operating state from ON to OFF. In one embodiment, additional sensors (such as ALS, ambient light sensor or camera 1004) can be used together (or only) to provide additional inputs that can be used to change the operating state of the tablet 1000 device in additional ways.
[000146] Figures 27A and 27B show a representative modality of separation without the use of hands of magnetically coupled objects. In particular, Figure 27A shows a magnetically attached configuration 1100 where the first magnetic attachment feature 1102 is magnetically attached to the second magnetic attachment feature 1104. In one embodiment, the first magnetic attachment feature 1102 may include an element 1106 that is responsive to an externally applied voltage (or current), provided, for example, by the voltage source (or current) 1108 to generate a magnetic field having a polarity P1 as long as the externally applied voltage (or current) is available.
[000147] In one embodiment, when no voltage or current is applied, element 1106 provides substantially little or no magnetic flux and is therefore not able to withstand magnetic fixation based on any intrinsic magnetic field alone. In one embodiment, the second magnetic clamping feature 1104 may include a magnetic element 1110 aligned and in proximity to the magnetic element 1106 when the first magnetic clamping feature 1102 is placed in proximity to the second magnetic clamping feature 1104. In one embodiment, the Magnetic element 1110 can have an intrinsic polarity P1 that is equal to the polarity of element 1106 when external current I or voltage V is applied as shown in Figure 27B. In this way, a liquid repulsive magnetic force in the form of a Feject ejection force can be generated between the element 1106 and the magnetic element 1110 over the duration of the availability of voltage V or current I. In this way, adjusting the size appropriately. , distance, magnetic properties, and electromagnetic properties, the first magnetic clamping feature 1102 and the second magnetic clamping feature 1104 can be separated from each other. For example, in a magnetically fixed state 1100, applying a voltage V or current I to the magnetic element 1106 can create a Feject ejection force that forces the first magnetic clamping feature 1102 and the second magnetic clamping feature 1104 to separate in state. separated from 1112 automatically or at least without the need for manual separation.
[000148] Figures 28A and 28B show the first magnetic clamping feature 1200 having a magnetic window 1202 capable of selectively controlling the leakage of magnetic flux B on the outer surface 1204 of housing 1206. In one embodiment, the magnetic window 1202 can be formed through a channel 1208 arranged to accommodate a magnetic fluid 1210. In one embodiment, the magnetic fluid 1210 can take the form of a ferrofluid which is a liquid that becomes strongly magnetized in the presence of a magnetic field. Ferrofluids are colloidal in nature formed by a liquid having ferromagnetic particles, or nanoscale ferrimagnetic particles suspended in a carrier fluid - usually an organic solvent or water. Each tiny particle is deeply coated with a surfactant to inhibit clumping. Large ferromagnetic particles can be removed from the homogeneous colloidal mixture, forming a separate agglomerate of magnetic dust when exposed to strong magnetic fields. The magnetic attraction of nanoparticles is weak enough that van de Waals' repulsion of the surfactant is sufficient to prevent a magnetic cluster. Ferrofluids generally do not retain magnetization in the absence of an externally applied field.
[000149] Therefore, in the inactive state (that is, Equation (1) is satisfied), the magnetic clamping feature 1200 can include magnetic elements 1212 embedded or in close proximity to housing 1206 where magnetic fluid 1210 interacts with the field magnetic generated by magnetic elements 1212. The magnetic nature of magnetic field 1210 prevents any leakage of flux on the outer surface 1204 of housing 1206, thus providing a boundary condition necessary to satisfy Equation (1). In this way, there is no need for moving magnetic elements 1212 in order to provide a magnetic surface M1 on the outer surface 1204. In one embodiment, the magnetic window 1202 can also include reservoirs 1214 (either one or a plurality) that provides sufficient volume for accommodate magnetic fluid 1210 as shown in Figure 28B.
[000150] In one embodiment, the second magnetic clamping feature 1216 may include a mechanism that can induce the magnetic fluid 1210 to migrate out of channel 1208 in one or both of the reservoirs 1214 to expose the magnetic elements 1212. Exposing itself the magnetic elements 1212, the magnetic surface M2 can be provided by satisfying Equation (2). In one embodiment, the mechanism used to migrate the magnetic fluid 1210 can take the form of magnets 1218 having a magnetic field resistance strong enough to overcome the attraction of magnetic elements 1212. Thus, the placement of the second magnetic clamping feature 1216 in proximity to the first magnetic clamping feature 1200 it can cause the magnetic window 1202 to change from a closed state (according to Equation (1)) to an open state (according to Equation (2)).
[000151] Figures 29A and 29B show the first magnetic fixation feature 1300 having a mechanism in the form of retaining magnets 1302. By providing magnets 1302, valuable space can be preserved. Since the strength and size of magnets 1302 can be well defined, the size and strength of activation magnets 1304 in the second magnetic clamping feature 1306 can also be well defined. For example, in order to activate the first magnetic clamping feature (that is, satisfying Equation (2)), magnets 1308 must move from inactive position X1 (magnetically attached to magnets 1302) to active position X2. This can be accomplished by placing active magnets 1304 in close proximity to magnets 1308. In one embodiment, the intrinsic magnetic resistance of magnets 1304 and 1308 can be adjusted to overcome the magnetic attraction between magnets 1302 and magnets 1308 causing the magnets 1308 separate from magnets 1302 and move towards magnets 1304 creating a magnetic surface M2 in the process (that is, satisfying Equation (2)).
[000152] Figures 30A and 30B show an embodiment of the first magnetic clamping feature 1300 having channels 1310 sized to accommodate moving magnets 1308 and retaining magnets 1302. In one embodiment, moving magnets 1308 can travel smoothly within channel 1310 and with little resistance due to the presence of a lubricant (not shown) between the moving magnets 1308 and the inner surfaces of the channels 1310.
[000153] Figures 31A-31C show another embodiment of the first magnetic clamping feature 1300 shown in Figures 30A-30B arranged to provide information based on a clamping configuration. In one embodiment, all, or at least some of the magnets 1302 are electrically isolated from the grounding of the chassis formed by the metal of the 1206 enclosure. In one embodiment, all, or at least some of the 1302 magnets can be coupled to a pickup circuit arranged for capture if magnet 1308 is attached to magnet 1302. In these cases where the pickup circuit captures that magnet 1308 is attached to magnet 1302, then a first logical value (“0” or “1”, whichever is considered appropriate) can be provided. Conversely, when the pickup circuit captures that magnet 1308 is not attached to magnet 1302, then a second logic value ("1" or "0) other than the first logic value can be provided. In one embodiment, information in the form of the first and second logical values can be used to identify a state of magnetic fixation. In one embodiment, the fixation state can identify a magnetically fixed object (see Table 1 shown in Figure 32). In one embodiment, the fastening information corresponding to the fastening status can be used to change an operational state of an electronic device, such as a tablet type 1000 device. For example, using the information provided in Table 1, if the circuit Capture Capture Capture Data {1,0,0,0,0,1} corresponding to a stylus, then the tablet device 1000 can change a current operating state to a state consistent with the capture of a stylus over a touchscreen to the touch.
[000154] Figures 32A and 32B show specific modalities of the first fixing feature 1300 shown in Figures 31A-31C. In one embodiment, retaining magnet 1302 can be electrically isolated from housing 102 and include an electrical contact 1320 electrically connected via line 1322 to the pickup circuit. As can be seen, when the holding magnet 1302 is not attached to the moving magnet 1308, there is no electrical path between the pickup circuit and the chassis ground, and therefore substantially no current flows corresponding to the second logic state. On the other hand, as shown in Figure 32B, when the moving magnet 1308 is in contact with the holding magnet 1302 and, more particularly, with the electrical contact 1320, the current path 1326 is provided allowing the current I to flow to the ground of the chassis. Figure 33 shows a table of operating magnetic codes and representative operating states.
[000155] Figure 34 is a block diagram of an array of 1600 functional modules used by an electronic device. The electronic device may, for example, be a 1500 tablet type device. The 1600 provision includes an electronic device 1602 that is capable of outputting media to a user of the portable media device, but also stores and restores data in relation to data storage. 1604. The 1600 layout also includes a 1606 graphical user interface (GUI) manager. The 1606 GUI manager operates to control the information being provided and displayed on a display device. The layout 1600 also includes a communication module 1608 that facilitates communication between the portable media device and an accessory device. In addition, provision 1600 includes an accessory manager 1610 that operates to authenticate and acquire data from an accessory device that can be attached to the portable media device.
[000156] Figure 35 is a block diagram of a 1650 electronic device suitable for use with the described modalities. Electronic device 1650 illustrates a circuitry of a representative computational device. The 1650 electronic device includes a 1652 processor that belongs to a microprocessor or a controller that serves to control the general operation of the 1650 electronic device. The 1650 electronic device stores media data pertaining to media items in a 1654 file system and a 1656 cache. The 1654 file system is typically a storage disk or a plurality of disks. The 1654 file system typically provides a high storage capacity for the 1650 electronic device. However, since access time to the 1654 file system is relatively slow, the 1650 electronic device can also include a 1656 cache. The 1656 cache it is, for example, a Random Access Memory (RAM) provided by a semiconductor memory. The access time for the 1656 cache is substantially shorter than for the 1654 file system. However, the 1656 cache does not have a large storage capacity for the 1654 file system. In addition, the 1654 file system, when active, consumes more power than the 1656 cache. Power consumption is often an issue when the 1650 electronic device is a portable media device powered by a 1674 battery. The 1650 electronic device can also include a 1670 RAM and Read-Only Memory ( ROM) 1672. ROM 1672 can store programs, utilities or processes to be executed in a non-volatile manner. RAM 1670 provides volatile data storage, just as for the 1656 cache.
[000157] The 1650 electronic device also includes a 1658 user input device that allows a 1650 electronic device user to interact with the 1650 electronic device. For example, the 1658 user input device can take a variety of forms, such as such as a button, a numeric keypad, a dial, a touchscreen, an audio input interface, a visual / image capture input interface, inserted in the form of sensor data, etc. In addition, the 1650 electronic device includes a 1660 screen (video screen) that can be controlled by the 1652 processor to display information to the user. A 1666 data bus can facilitate data transfer between at least the 1654 file system, the 1656 cache, the 1652 processor, and the 1663 CODEC.
[000158] In one embodiment, the 1650 electronic device serves to store a plurality of media items (for example, songs, podcasts, etc.) in the 1654 file system. When a user wants the electronic device to play a media item In particular, a list of available media items is displayed on screen 1660. Then, using the 1658 user input device, a user can select one of the available media items. The 1652 processor, upon receipt of a selection of a particular media item, provides the media data (for example, audio file) for the particular media item to a 1663 encoder / decoder (CODEC). Then, the CODEC 1663 produces analog output signals to a 1664 speaker. The 1664 speaker can be a speaker internal to the 1650 electronic device or external to the 1650 electronic device. For example, headsets or headphones that connect to the 1650 electronic device would be considered as an external speaker.
[000159] The 1650 electronic device also includes a 1661 network / bus interface that attaches to a 1662 data link. The 1662 data link allows the 1650 electronic device to attach to a host computer or accessory devices. The 1662 data link can be provided via a wired connection or a wireless connection. In the case of a wireless connection, the 1661 network / bus interface can include a wireless transceiver. Media items (media assets) can belong to one or more different types of media content. In one embodiment, the media items are audio tracks (for example, songs, audio books, and podcasts). In another modality, the media items are images (for example, photos). However, in other modalities, media items can be any combination of audio, graphics or visual content. The 1676 sensor can take the form of a set of circuits to detect any number of stimuli. For example, the 1676 sensor may include a Hall effect sensor responsive to the external magnetic field, an audio sensor, a light sensor, such as a photometer, and so on.
[000160] The various aspects, modalities, implementations or resources of the described modalities can be used separately or in any combination. Various aspects of the described modalities can be implemented by software, hardware or a combination of hardware and software. The described modalities can also be incorporated as a computer-readable code in a non-transitory computer-readable medium. The computer-readable medium is defined as any data storage device that can store data that can be later read by a computer system. Examples of the computer-readable medium include read-only memory, random access memory, CD-ROMs, DVDs, magnetic tape, and optical data storage devices. The computer-readable medium can also be distributed by computer systems coupled in a network so that the computer-readable code is stored and executed in a distributed manner.
[000161] The previous description, for the sake of explanation, used a specific nomenclature to provide a complete understanding of the described modalities. However, it will be apparent to an individual skilled in the art that specific details are not necessary in order to practice the described modalities. Therefore, the previous descriptions of the specific modalities described here are presented for purposes of illustration and description. They are not intended to be exhaustive or to limit modalities to the precise forms revealed. It will be apparent to an individual with common knowledge in the art that many modifications and variations are possible in view of the previous teachings.
[000162] The advantages of the described modalities are many. Different aspects, modalities or implementations can produce one or more of the following advantages. Many features and advantages of the present modalities are apparent from the written description and, therefore, the attached claims are intended to cover all the features and advantages of the invention. In addition, since several modifications and alterations will occur promptly to those skilled in the art, the modalities should not be limited to the exact construction and operation as illustrated and described. Therefore, all modifications and suitable equivalents can be used as long as they are within the scope of the invention.
