Description

Technical Field

[0001] Cross - Reference to Related Applications This PCT patent application claims priority and benefit to U.S. Provisional Patent Application No. 63 / 364,479, filed on May 10, 2022, entitled "DOCKABLE AND UNDOCKABLE MULTI - PURPOSE ELECTRONIC TABLET DEVICE", the entire disclosure of which is incorporated herein by reference for all purposes.

Background Art

[0002] Electronic tablet devices are becoming increasingly popular devices due to their larger display screens and touch - input capabilities. However, problems arise when a user places a tablet device on a surface and wishes to continue interacting with the device to consume media content. Tablet devices, by their form factor, are generally designed to rest on a flat surface, which allows the user to view the display by looking downwards. When a user wishes to place a tablet device on a kitchen counter, for example, to view a recipe or watch a basketball game while preparing a meal, the problem that arises is stabilizing the device in an upright position such that the display screen is substantially perpendicular to the counter.

[0003] Tablet computing devices, sometimes referred to as tablets or tablet computers, are generally flat, lightweight devices that include a touch - screen display. Tablets are battery - powered and can be plugged in to recharge the tablet's battery.

Summary of the Invention

[0004] This book describes techniques for a multi-purpose electronic tablet device that can be docked and undocked. These techniques enable a tablet device operable in a tablet device mode to be docked to a base, where the base secures the tablet device in an upright position to view the display screen of the tablet device substantially horizontally. The tablet device can also be electrically coupled to the base, enabling communication between the tablet device and the base and enabling power transfer from the base to the tablet device to charge the battery of the tablet device.

[0005] In an aspect, the tablet device includes electrical contacts (e.g., pogo pads) on a rear surface that is opposite the display screen of the tablet device. When docked to the base, the electrical contacts electrically couple to corresponding receptacle contacts on the base, forming a robust physical connection that enables the transfer of current and electrical signals. The electrical contacts can be positioned at any suitable location on the rear surface, thereby enabling the electrical contacts to couple (e.g., mate) to the corresponding receptacle contacts on the base.

[0006] The tablet device can be docked (e.g., attached, coupled, secured) to the base via a coupling mechanism that can include a magnetic coupling mechanism or a mechanical coupling mechanism. For example, magnets can be mounted on the base and / or the tablet device to generate a magnetic attraction that securely connects and holds the tablet device to the base. With sufficient counterforce (e.g., pulling) applied by the user, the tablet device can be detached from the base.

[0007] The tablet device and the base together form a modular system. In one example, the base may include an audio output device (e.g., a speaker) to provide audio output from the tablet device. Digital signals can be communicated from the tablet device to the base via electrical contacts and corresponding receptacle contacts, and the base can output an audio signal via the audio output device accordingly. In this way, the tablet device and the base can communicate via a physical connection rather than via wireless communication (e.g., Bluetooth®). However, in some embodiments, the tablet device may communicate with the base via wireless communication.

[0008] According to at least some embodiments of the present disclosure, a tablet computer system includes a dock and a tablet computer removably dockable to the dock. The tablet computer includes an electronic display and an enclosure housing the electronic display. The tablet computer includes a first plurality of magnets arranged to magnetically couple with a second plurality of magnets of the dock. The first plurality of magnets are formed in an arrangement including at least four groups of magnets on each side surface of the enclosure. At least four groups of magnets on a first side surface of the enclosure are in a mirrored configuration with respect to at least four groups of magnets on a second side surface of the enclosure. At least three of the groups of magnets on each side surface of the enclosure are horizontally oriented, and a fourth group of magnets on each side surface of the enclosure is vertically oriented. The three groups of magnets on each side surface of the enclosure include alternating N and S poles across the three groups of magnets, and the two innermost groups of magnets include matching N and S poles across the two innermost groups of magnets.

[0009] The tablet computer system may optionally include at least some of the following embodiments. The tablet computer system may further include a shunt coupled to one or more magnets to direct a magnetic field associated with the one or more magnets. When the tablet computer is docked, the gap between the first plurality of magnets and the second plurality of magnets may be in the range of 1.65 millimeters (mm) to 2.5 mm. The tablet computer system may further include an excitation magnet on the enclosure to detect the tilt of the tablet computer. The tablet computer system may further include a group of additional magnets arranged along the longitudinal axis of the enclosure. The group of additional magnets may magnetically couple with a third plurality of magnets of an alternative dock. Each group of magnets may include two magnets. The magnets within each group of magnets may be arranged with opposing N and S poles. The magnets within each group of magnets may be arranged such that both poles are oriented towards each other.

Mode for Carrying Out the Invention

[0017] Various embodiments are described with respect to an electronic device and a dock. The electronic device and the dock have corresponding sets of magnets arranged to optimize magnetically docking and undocking an electronic device (e.g., a tablet computer) from the dock. The electronic device may include a first set of magnets. The first set of magnets is arranged to magnetically couple with a second set of magnets of the dock.

[0018] The magnet can be used to couple and align a tablet computer to a charging dock. As detailed herein, the magnet can be used to couple two devices, such as coupling a tablet computer and a dock. The attractive force between the magnets within the tablet computer and within the dock needs to be strong enough to prevent unnecessary detachment when the tablet computer hits accidentally, or when the surface on which the dock is placed hits accidentally. For example, the magnets can be arranged and designed to cancel out any impact impulse generated within the surface supporting the tablet dock system. The attractive force of the magnet also needs to be strong enough to resist the inclination of the tablet computer and the dock, or the unnecessary undocking of the tablet computer from the dock when the user interacts with the docked tablet computer.

[0019] When the tablet computer is attached to the dock, the first plurality of magnets included within the tablet computer can magnetically couple with the second plurality of magnets present within the dock. The magnets can not only hold the tablet computer in a predetermined position on the dock, but also function to align the plurality of contact pads of the tablet computer with the contact pins of the dock. The contact pads enable the exchange of electrical signals, which may include data, power, or both, between the dock and the tablet computer.

[0020] The embodiments detailed herein focus on an electronic device and a dock having an arrangement of magnets to enable coupling of the electronic device and the dock. In some embodiments, the electronic device is a tablet computer that is a component of a tablet computer system. Specifically, the tablet computer can function as a home assistant device and / or hub for managing smart home devices within an environment. The tablet computer may be able to record video, communicate with a remote server system, and interact with a user via verbal communication. For example, the home assistant device may provide automated or voice control of devices, appliances, and systems such as heating, ventilation, and air conditioning (「HVAC」) systems, lighting systems, home theaters, entertainment systems, and security systems. The smart home network may include a control panel that a person can use to input setpoint, preference, and schedule information, and the smart home network uses the setpoint, preference, and schedule information to provide automated control of various devices, appliances, and systems within the home. For example, a person may input a schedule indicating when they will be away from home, and the smart home network uses this information in combination with information obtained from various devices within the home to detect unauthorized entry when the user is absent. The tablet computer may remain docked to charge its battery and use other functions of the dock such as an integrated speaker. The tablet computer may be removed from the dock for convenience of use or display in another location. When not in use (regardless of whether it is docked, undocked, or both), a photo or photo album selected by the user may be presented by the tablet.

[0021] Many other types of electronic devices can benefit from the optimized arrangement(s) of magnets described herein. For example, smartphones, gaming consoles, e - book readers, personal digital assistants (PDAs), digital paper tablets, and smart picture frames can benefit from the various embodiments of the battery housing detailed herein. Further, the electronic device can be an assistant device (e.g., Google® Nest® Hub, Google® Nest® Hub Max), a home automation controller (e.g., a controller for an alarm system, thermostat, lighting system, door lock, electric door, etc.), a gaming console (e.g., a game system, game controller, data glove, etc.), a communication device (e.g., a smartphone such as Google® Pixel® Phone, cellular phone, mobile phone, cordless phone, handset, wireless telephone), and / or other computing devices (e.g., a tablet computer, phablet computer, notebook computer, laptop computer, etc.).

[0022] This document describes a dockable and undockable multi - purpose electronic tablet device. The technology described herein includes an electronic device (e.g., a tablet device) that can operate as a stand - alone computing device when undocked and as a virtual assistant device when docked to a base.

[0023] The tablet device may be a landscape first tablet for docking purposes, and thus, when docked to the base, the tablet device is oriented in a horizontal orientation. Accordingly, the tablet device may have a characteristic array in landscape first orientation. The tablet device includes electrical contacts (e.g., pogo pads) configured to be exposed to the environment and physically connect to corresponding receptacle contacts on the base. Such a physical connection enables the tablet device to communicate with the base without wireless pairing. Further, the tablet device may include a wear foot, which significantly reduces slidable movement on the surface, especially when the tablet device is docked to the base in an upright position (e.g., a position substantially perpendicular to a substantially horizontal surface).

[0024] The features and concepts of the technology described for a dockable and undockable multi-purpose electronic tablet device can be implemented in any number of different environments, but the aspects are described in the context of the following examples.

[0025] Exemplary Devices and Systems FIG. 1 shows an exemplary embodiment of a system 100 having a dockable and undockable multi-purpose tablet device. In the illustrated example, system 100 includes an electronic device 102 and a base 104 that are coupleable to each other. The base 104 not only supports the electronic device 102 in an upright position to enable a substantially horizontal viewing angle for the user, but the base 104 also provides additional functionality to the electronic device 102. For example, the base 104 may be a charger for the electronic device 102, a speaker for the electronic device 102, a keyboard for the electronic device 102, a stand for the electronic device 102, a handheld controller for the electronic device 102, and the like.

[0026] The electronic device 102 includes a battery 106, one or more processors 108, a touch-sensitive display device 110 (e.g., an electronic display), as well as an operating system 112 and an application 114, and includes various components that enable the electronic device 102 to operate as a mobile computing device. The electronic device 102 also includes electrical contacts 116, which enable the electronic device 102 to physically connect to another device (e.g., a base 104). In some aspects, the electrical contacts 116 are exposed through the housing 118 of the electronic device 102 to enable coupling without the user first having to remove a cover. However, in some embodiments, the electrical contacts 116 may include a cover to protect against elements including environmental and water intrusion.

[0027] The battery 106 may be any suitable rechargeable battery. An exemplary battery 106 is a lithium-ion battery. The touch display device 110 is a touch-sensitive display configured to receive and detect touch input from a user. The touch display device 110 is used to render digital content including media content (e.g., images, videos).

[0028] The base 104 includes additional electrical contacts (e.g., corresponding receptacle contacts 120) configured to couple to the electrical contacts 116 on the electronic device 102 to provide a physical electrical connection for communication and power transfer. This physical connection between the electrical contacts 116 on the electronic device 102 and the corresponding receptacle contacts 120 on the base 104 enables the electronic device 102 and the base 104 to communicate with each other without the user having to connect a cable (plug in) between the electronic device 102 and the base 104 and without having to establish a wireless connection between the electronic device 102 and the base 104.

[0029] The base 104 can be connected to an external power source 122 (e.g., direct current provided via an outlet) via one or more wires (e.g., power cord 124). The application 114 and / or the operating system 112 can be implemented as computer-readable instructions on a computer-readable medium (e.g., a storage medium) and executed by a processor(s) 108 to provide some or all of the functions described herein. The computer-readable medium provides a data storage mechanism for storing various device applications 114, operating systems 112, memory / storage, and other types of information and / or data related to the operation of the electronic device 102. For example, the operating system 112 can be maintained as a computer application within the computer-readable medium and executed by a processor(s) 108 to provide some or all of the functions described herein. The device application 114 can include any form of control application, software application, or a device manager such as a module for signal processing and control. The device application 114 can also include system components, engines, or managers to implement technologies for a dockable and undockable multi-purpose electronic tablet device. The electronic device 102 may include one or more machine learning systems or may be able to access one or more machine learning systems.

[0030] The base 104 can also include an audio output device 126 (e.g., a speaker) configured to provide audio output by the electronic device 102. When the electronic device 102 is docked to the base 104, the electronic device 102 can output audio via the audio output device 126 without wirelessly pairing (or previously wirelessly pairing) with the base 104 and / or the audio output device 126.

[0031] In one aspect, the base 104 includes circuitry for implementing a voice-activated virtual assistant 128 that can initiate corresponding functions including processing audio input from a user to identify a query or command and providing an audio output in response to the query or command. The virtual assistant 128 can be used to perform various tasks including searching the Internet, scheduling events and alarms, controlling home automation, and controlling Internet of Things (IoT) devices. When the electronic device 102 is docked to the base 104, it operates as a display for a user interface associated with the virtual assistant 128.

[0032] In an embodiment, the electronic device 102 and the base 104 form a modular system. For example, when the electronic device 102 is docked, the system operates as a virtual assistant having a user interface displayed via the electronic device 102 and audio output by the base 104. When the electronic device 102 is undocked, the electronic device 102 operates as a stand-alone tablet device.

[0033] The electronic device 102 can also be configured to communicate with one or more devices or servers via a network (e.g., network 130). By way of non-limiting example, the electronic device 102 can communicate data via a local area network (LAN), wireless local area network (WLAN), personal area network (PAN), wide area network (WAN), intranet, Internet, peer-to-peer network, point-to-point network, or mesh network.

[0034] Figure 2 shows a front view 200 of the electronic device 102 of FIG. 1. As shown, the electronic device 102 includes a touch display device 110. The touch display device 110 defines a front surface 202 of the electronic device 102 that is substantially planar. The housing 118 includes a bezel around the touch display device 110. The electronic device 102 also includes a first camera 204 (e.g., a front camera) positioned (internally) within the housing 118 and oriented in a direction substantially perpendicular to the front surface 202. Further, the electronic device 102 is shown as having a longitudinal axis 206 (e.g., the x-axis), a transverse axis 208 (e.g., the y-axis), and a vertical axis (e.g., the z-axis). In an aspect, the first camera 204 is aligned with (e.g., centered on) the transverse axis 208 and offset from the longitudinal axis 206 such that the first camera 204 is centered on the "upper" portion of the front surface 202 when the electronic device 102 is in a landscape orientation.

[0035] Figure 3A shows a top view 300 of the electronic device 102 of FIG. 1. This top view 300 shows a side surface (e.g., the "upper" side) of the electronic device 102 that is adjacent to the front surface 202 and intersects the transverse axis 208 (and is parallel to the longitudinal axis 206). In an aspect, the electronic device 102 may include one or more input mechanisms (e.g., a microphone port 302, a volume control button 304, a power button 306) disposed on the upper side of the electronic device 102. Each microphone port 302 may be disposed within the housing of the electronic device 102 and aligned with an audio sensor (e.g., a microphone) configured to detect voice input by a user.

[0036] Figure 3B shows a bottom view 310 of the electronic device 102 of FIG. 1. This bottom view 310 is beside the front face 202 and shows another side (e.g., the "bottom" side) of the electronic device 102 that is opposite to the upper side shown in FIG. 3A. In some aspects, when the electronic device 102 is positioned in a lateral orientation and is either coupled to a base or leaning against an object, the bottom side is resting on the surface. To reduce and / or prevent the electronic device 102 from sliding on the surface, the electronic device 102 includes one or more wear feet 312. The wear feet 312 protrude from the outer surface of the electronic device 102. Further, the wear feet 312 include a high-friction material to reduce slidable movement along the surface. In an aspect, the wear feet 312 are arranged in columns parallel to the longitudinal axis 206 of the electronic device 102.

[0037] Figure 4 shows a rear view 400 of the electronic device 102 of FIG. 1. The illustrated example shows the rear face 402 of the electronic device 102 that is opposite to the front face 202 defined by the touch display device 110. The rear face 402 includes an opening for a second camera 404 (e.g., a rear camera). The second camera 404 is disposed within the housing of the electronic device 102 and faces in a direction parallel to the vertical axis (e.g., the z-axis). Also, electrical contacts 116 are exposed from the rear face 402. In some aspects, the electrical contacts 116 include a row of electrical connector mechanisms (e.g., pogo pads). The electrical contacts 116 can be arranged in any suitable pattern including one or more rows substantially parallel to the longitudinal axis 206 and one or more columns substantially parallel to the transverse axis 208. The electrical contacts 116 are arranged in a suitable manner to correspond to corresponding receptacle contacts (e.g., electrical contacts 120) on the base. In some embodiments, the electrical contacts 116 are centered with respect to the transverse axis 208 and are positioned at a location on the rear face 402 that is offset from the longitudinal axis 206 by an offset distance (e.g., 4 centimeters (cm), 5 cm, 6.25 cm, 7.3 cm, 8 cm). In an aspect, the electrical contacts 116 may be offset from the bottom side of the electronic device 102 by a predetermined distance (e.g., 2.5 cm, 3 cm, 3.75 cm, 5 cm).

[0038] FIG. 5A shows a left elevation view 500 of the electronic device 102 of FIG. 1. This illustrated example shows a side of the electronic device 102 (e.g., the "left" side with respect to the front view shown in FIG. 2) that is next to the front face 202 and intersects the vertical axis 206. The electronic device 102 includes one or more openings 502-1 for audio output by a speaker. The electronic device 102 may also include a port 504 for an audio sensor (e.g., a microphone) on the left side of the device. Thus, the electronic device 102 may include audio sensors on both the upper side and the left side (and / or right side).

[0039] FIG. 5B shows a right elevation view 510 of the electronic device 102 of FIG. 1. This illustrated example shows another side of the electronic device 102 (e.g., the "right" side with respect to the front view shown in FIG. 2) that is next to the front face 202 and is opposite the left side shown in FIG. 5A. The electronic device 102 may include one or more openings 502-2 for audio output by a speaker on the right side. The electronic device 102 may also include an input / output port (e.g., a Universal Serial Bus type-c (USB-C) port 506), or any other I / O port suitable for cable attachment for power transfer and electronic communication.

[0040] Since the electronic device 102 is a landscape-first orientation device, the top and bottom sides are longer than the shorter left and right sides. As described above, the front camera is centered on the electronic device 102 with respect to the landscape orientation and is disposed near the top. The top also includes a microphone port 302 for an audio sensor that detects the user's voice and / or other sounds. The microphone port 302 is disposed on the top side to reduce the likelihood of interference by any object when the electronic device 102 is docked or when it is placed on a surface and leaned against another surface in the landscape orientation. Also, as described above, the electronic device 102 has openings 502-1 and 502-2 aligned with speakers on the left and right sides thereof, respectively, for outputting audio toward both the left and right sides of the electronic device 102. Further, as described above, the wear foot 312 is disposed on the bottom side of the electronic device 102 and functions to reduce or prevent slidable movement of the bottom side on a surface, such as when the electronic device 102 is placed on a surface and leaned against another surface. The specific arrangement of the features of the electronic device 102 provides a feature arrangement for the landscape-first orientation, as described herein.

[0041] Unless the context dictates otherwise, the use of the word "or" in this specification may be construed as an "inclusive or" or the use of a term that permits the inclusion or application of one or more items joined by the word "or" (e.g., the phrase "A or B" may be interpreted as permitting only "A", only "B", or both "A" and "B"). Also, as used herein, the phrase referring to "at least one" of a list of items refers to any combination of those items, including a single element. For example, "at least one of a, b, c" covers not only a, b, c, a-b, a-c, b-c, a-b-c, but also any combination that includes multiples of the same element (e.g., a-a, a-a-a, a-a-b, a-a-c, a-b-b, a-c-c, b-b, b-b-b, b-b-c, c-c, c-c-c, or any other order of a, b, and c). Further, the items shown in the accompanying drawings and the terms described herein may refer to one or more items or terms, and thus, the singular or plural forms of the items and terms in this description requirement may be referred to interchangeably.

[0042] Embodiments of a dockable and undockable multi-purpose electronic tablet device are described in language specific to certain functions and / or methods, but the subject matter of the appended claims is not necessarily limited to the specific functions or methods described. Rather, the specific functions and methods are disclosed as exemplary embodiments of a dockable and undockable multi-purpose electronic tablet device, and other equivalent functions and methods are intended to be within the scope of the appended claims. Further, it should be understood that various different aspects are described and that each described aspect can be implemented independently or in relation to one or more of the other described aspects.

[0043] FIG. 6 shows a side view of a system 600 including an embodiment of an electronic device attached to a dock. As can be seen from the side view, the electronic device 602 is docked with the dock 604. Region 606 indicates the location where the rear surface 608 of the electronic device 602 contacts the dock 604.

[0044] Within region 610, a first plurality of magnets are present within the electronic device 602. At corresponding positions within region 606, a second plurality of magnets are present within the dock 604. The magnets are arranged such that when in proximity, the magnets of the electronic device 602 are attracted to the magnets of the dock 604 to assist in correctly positioning, aligning, and holding the dock 604 in the correct position on the electronic device 602. In other embodiments, regions 606 and 610 may extend further upward on the dock 604 and / or may extend along the length of the dock 604 that contacts the electronic device 602. For example, regions 606 and 610 may be of any size and may be located at any position on the electronic device 602 and / or the dock 604.

[0045] The arrangement of the magnets at the interface between the electronic device and the dock is optimized according to various embodiments of the present invention. For example, it has been found that the user's "sensation" of docking and undocking the electronic device from the dock varies significantly based on the arrangement of the magnets arranged on the electronic device and the dock. Accordingly, the arrangement of the magnets described throughout the present disclosure is optimized to reduce the number of "false home" (e.g., misalignment events) when the user docks the electronic device to the dock and the number of tipping events when the user interacts with the electronic device docked to the dock.

[0046] Referring now to FIG. 7, a cross-sectional view of an electronic device 700 is shown. The electronic device 700 may be a tablet computer configured to dock using magnets and removably dockable from a dock using magnets. In particular, the electronic device 700 may be the smart home assistance device detailed above. The electronic device 700 includes a plurality of magnets 702 arranged to magnetically couple with a plurality of other magnets of the dock. The plurality of magnets 702 are formed in an arrangement having at least four groups 704 on a first side surface 706 and a second side surface 108 of the electronic device 700 (more specifically, the enclosure 710 of the electronic device 700). In various embodiments, at least four groups 704 on the first side surface 706 are mirror configured with respect to at least four groups 704 on the second side surface 708. For example, the size and position of at least four groups 704 of magnets are reflected across the longitudinal axis 712 of the electronic device 700.

[0047] In various embodiments, the plurality of magnets 702 are grouped (e.g., arranged) in pairs as shown. For example, pairs of magnets within the plurality of magnets 702 have north and south orientations that are in-plane and opposite with respect to the surface of the electronic device 700. For example, the magnets within each group of magnets may be arranged such that their two poles are oriented towards each other. Such an arrangement of opposing poles can concentrate the magnetic field to facilitate alignment of the electronic device 700 when docked and prevent misalignment between the electronic device 700 and the dock. In other embodiments, the plurality of magnets 702 are arranged in trios. The pairs of the plurality of magnets 702 may have polarities such that they magnetically attract corresponding magnets within the dock. For example, the magnets within the plurality of magnets 702 are oriented within the electronic device 700 such that the corresponding magnets within the dock have polarities opposite to those of the magnets within the plurality of magnets 702. Such an arrangement enables the first plurality of magnets (e.g., magnets 702) of the electronic device 700 to be attracted to the second plurality of magnets of the dock. The arrangement and number of the plurality of magnets 702 may vary. For example, the electronic device 700 shows 16 magnets out of the plurality of magnets 702. Accordingly, the second plurality of magnets may include 16 magnets corresponding to the plurality of magnets 702. In other embodiments, any number of magnets may be grouped together. For example, one magnet, three magnets, two pairs of magnets, etc. may form a group. In yet another example, the number of magnets within a group may vary (e.g., one magnet in one group and two magnets in a second group, etc.).

[0048] The electronic device 700 may further include a group of additional magnets 714 that are typically arranged along the vertical axis of the electronic device 700. As shown, the group of additional magnets 714 is arranged in two columns, with one column on each side of the vertical axis. Each column includes three magnets, although any number of magnets may be included in the group of additional magnets 714 or in each column of the group of additional magnets. The group of additional magnets 714 may be configured to magnetically couple with different magnets of an alternative dock. For example, in various applications, a smaller dock may be desired as a backup charger or alternative docking station within the user's home. The alternative smaller dock may be interchangeable with a main larger dock such as dock 604 shown in FIG. 6 or described throughout the present disclosure. In various embodiments, the electronic device 700 does not include a group of additional magnets 714.

[0049] The electronic device 700 may further include one or more excitation magnets 716 located on the electronic device 700 to detect the tilt of the electronic device 700. For example, the excitation magnet 716 may be part of an inclinometer or, in other cases, may be configured to transmit a signal indicating the tilt when the electronic device 700 is tilted, as would be understood by one of ordinary skill in the art. In some embodiments, the excitation magnet 716 is used in conjunction with a Hall effect sensor on the electronic device 700 to detect whether the electronic device 700 is close enough to a dock to enable charging.

[0050] In at least some embodiments, one excitation magnet 716 is located on each side of the longitudinal axis 712 of the electronic device 700 to detect an inclination and to ensure that charging occurs only when the electronic device 700 is placed on the dock within a predetermined inclination. For example, the electronic device 700 may include a series of contact pads 717 (such as the electrical contacts 116 and corresponding receptacle contacts 120 described above for providing power and signals from the dock to the electronic device 700 or vice versa), and charging may occur only when the inclination is within a predetermined range and the series of contact pads 717 are engaged. For example, even if only one excitation magnet 716 on each side of the longitudinal axis 712 of the electronic device 700 is within a predetermined inclination range, but the four pins are substantially aligned, charging will not occur. When each of the excitation magnets 716 is given a predetermined inclination, a short circuit of the corresponding receptacle contacts (such as leaf springs) that may occur when the contact pads 717 are misaligned is reduced (for example, when a leaf spring configured to provide power is aligned with a leaf spring configured to provide data, a short circuit of the material may occur in one of the leaf springs).

[0051] In some embodiments, any of the magnets described with respect to the electronic device 700 may include a shunt (not shown) coupled to the magnet to direct a magnetic field associated with the one or more magnets. For example, the magnetic field of the magnet must move at least through the enclosure 710 of the electronic device 700 to magnetically couple (e.g., attract) the corresponding magnet on the dock. The shunt can be used to further define the direction of the magnetic field to optimize the magnetic force and the user experience of docking / undocking the electronic device 700 from the dock. For example, when the magnetic force of the magnet is exaggerated by an additional shunt mounted on the magnet, the user may more confidently dock the electronic device 700 to the dock.

[0052] In various embodiments, the gap is optimized between magnet 702 and corresponding magnets within the dock. When the electronic device is docked to the dock, the gap is in the range of 1.65 mm to 2.5 mm. The gap is optimized to further direct and integrate magnetic forces between a plurality of corresponding magnets within electronic device 700 and the dock.

[0053] Referring now to FIG. 7B, the plurality of magnets 702, the group of additional magnets 714, and the array of excitation magnets 716 shown in FIG. 7A are shown with other components of electronic device 700 removed for simplicity. The arrangement of magnets within electronic device 700 is optimized to improve the user experience when docking and undocking electronic device 700 from the dock. The arrangement of magnets, according to various embodiments described herein, optimally includes an alternating polarity arrangement along the outermost three groups 720 of magnets 702 on the first side 706 and the second side 108 of the longitudinal axis 712. At least four of these groups 704 are arranged horizontally and are described in more detail below. Further, the arrangement of magnets includes that two vertically oriented groups of magnets 702 (e.g., the fourth group 722) include matching north and south poles across the two groups, which is described in further detail below.

[0054] As described with respect to FIG. 7A, at least four groups 704 of magnets 702 on the first side 706 are mirror configured with respect to at least four groups 704 of magnets 702 on the second side 708 as shown. The mirror configuration advantageously prevents or reduces the occurrence of "false homes" (e.g., when the user brings the electronic device close to the dock, the electronic device is attracted to the wrong magnet on the dock and a false home occurs when the electronic device is temporarily displaced from the dock before being centered again).

[0055] According to the embodiments described in this specification, at least three of the at least four groups 704 on the first side 706 and the second side 708 (e.g., the outermost three groups 720) are horizontally oriented, and the fourth group 722 is vertically oriented. Orienting the majority of the groups of magnets horizontally on each side of the electronic device provides stability to the system, especially while pressing a button. For example, button pressing may include the user interacting with a button (such as the volume control button 304 and / or the power button 306 described with respect to FIG. 3A) along the upper edge of the electronic device 700. When the groups are horizontally oriented, the magnetic strength in the y-direction is increased, and as a result, any tilt resulting from the interaction with the upper edge or corner of the electronic device is minimized. The outermost three groups 720 on the first side 706 and the second side 108 include alternating N and S poles across the three outermost groups 720 (e.g., from left to right) as indicated by the N polarity of "N". The alternating polarities further prevent the generation and misalignment of false homes of the electronic device and the dock by reducing the number of magnets available in the correct orientation close to each other (e.g., such that the magnets are attracted to each other). As a result of the docking experience, a fluid movement of bringing the electronic device close to the dock and a magnetic coupling of the electronic device and the dock occur. The fluid docking movement may be substantially horizontal since the majority of the horizontally placed magnets guide the electronic device across the surface of the dock to the final docking position of the electronic device.

[0056] When a group of magnets (e.g., the fourth group 722) is vertically oriented, it facilitates the alignment of the electrical contact pads of the electronic device 700 with the pins of the dock (such as the electrical contacts 116 and pins described above for providing power and signals to or from the electronic device 700). The vertically oriented group of magnets (e.g., the fourth group 722) further guides the electronic device 700 vertically into position on the surface of the dock, for example, when the electronic device 700 is brought slightly above or below the array of magnets, specifically the outermost three horizontally aligned groups 720.

[0057] In various embodiments, the two innermost groups 724 of magnets include matching N and S poles across the two innermost groups 724. In other words, the two innermost groups 724 have the same polarity facing the longitudinal axis 712. This "L-shaped" or "arc-shaped" polarity provides support to the electronic device 700 when the electronic device 700 is docked and the user is interacting with buttons (such as the volume control button 304 and / or the power button 306 described with respect to FIG. 3A) along the upper edge of the electronic device 700. For example, when the user presses the volume button or the power button, the user is applying a downward force from the upper edge of the electronic device. The magnets must be arranged to counteract that downward force so that the electronic device is not unexpectedly released from the dock. The arc-shaped polarity resulting from the matching polarities facing inward acts to cancel out any rocking motion that the docked electronic device would experience when the user interacts with the buttons on the upper edge of the electronic device.

[0058] Referring now to FIG. 7C, an array of magnets having optimized distances according to at least some embodiments of the present disclosure is shown. All of the distances shown have a tolerance of ±0.1 mm (including both ends). For example, a distance of 1.0 mm between groups of magnets is understood to include 0.9 mm and 1.1 mm, and any integer therebetween. The same numbering as in FIGS. 7A-7B has the same definitions as described above with respect to the other figures.

[0059] A plurality of magnets 702 are arranged in accordance with at least some embodiments of the present disclosure. The plurality of magnets 702 are mirrored on the first side 706 and the second side 108 of the longitudinal axis 712, and it is assumed that the distances shown on the first side 706 of the plurality of magnets 702 are the same between the corresponding magnets on the second side 708. Starting from the first side 706, d 1 is 42.72 mm, d 2 is 9.64 mm, d 3 is 9.5 mm, d 4 is 11.14 mm, d 5 is 9.57 mm, d 6 is 20.93 mm, d 7 is 75.86 mm, d 8 is 10.00 mm, d 9 is 1.4 mm, d 10 is 1.0 mm.

[0060] Referring now to FIG. 8A, a top cross-sectional view of dock 800 is shown. Dock 800 may be a dock configured to magnetically couple with an electronic device (such as electronic device 700 or any tablet computer described herein). In particular, dock 800 may be used with an electronic device as part of a smart home assistance device as detailed above. Dock 800 includes a plurality of magnets 802 arranged to magnetically couple with a plurality of other magnets of the electronic device. The plurality of magnets 802 are formed in an arrangement having at least four groups 804 on a first side surface 806 and a second side surface 808 of dock 800 (more specifically, on faceplate 810 of dock 800). In various embodiments, at least four groups 804 on the first side surface 806 are mirror configured with respect to at least four groups 804 on the second side surface 808. For example, the size and position of at least four groups 804 of magnets are reflected across the longitudinal axis 812 of dock 800, similar to at least four groups 704 of magnets described with respect to electronic device 700.

[0061] In various embodiments, the plurality of magnets 702 are grouped (e.g., arranged) in pairs as shown. For example, pairs of magnets within the plurality of magnets 802 have north and south orientations that are in-plane and face each other with respect to the surface of the dock 800. Such an arrangement of opposing poles can concentrate the magnetic field to facilitate alignment of the electronic device when docked to the dock 800. In other embodiments, the plurality of magnets 802 are arranged in trios. Pairs of the plurality of magnets 802 may have polarities such that they magnetically attract corresponding magnets within the electronic device as detailed above. For example, the magnets within the plurality of magnets 802 are oriented within the dock 800 such that the corresponding magnets within the electronic device have polarities opposite to those of the magnets within the plurality of magnets 802. Such an arrangement enables the first plurality of magnets (e.g., magnets 802) of the dock 800 to attract the second plurality of magnets of the electronic device. The arrangement and number of the plurality of magnets 802 may vary. For example, the dock 800 shows 16 magnets of the plurality of magnets 802. Accordingly, the second plurality of magnets may include 16 magnets corresponding to the plurality of magnets 802. In other embodiments, any number of magnets may be grouped together. For example, one magnet, three magnets, two pairs of magnets, etc. may form a group. In yet another example, the number of magnets within a group may vary (e.g., one magnet within one group and two magnets within a second group, etc.).

[0062] In some embodiments, any of the magnets described with respect to the dock 800 may include a shunt (not shown) coupled to the magnet to direct the magnetic field associated with the one or more magnets. For example, the magnetic field of the magnet must travel at least through the faceplate 810 of the dock 800 in order to magnetically couple (e.g., attract) a corresponding magnet on the electronic device. The shunt can be used to further define the direction of the magnetic field to assist in optimizing the magnetic force and docking / undocking of the electronic device from the dock 800, as detailed above with respect to the shunt of the electronic device 700.

[0063] In various embodiments, the gap is optimized between magnet 802 and corresponding magnets within the electronic device. When the electronic device is docked to the dock, the gap is in the range of 1.65 mm to 2.5 mm. The gap is optimized to further direct and integrate magnetic forces between a plurality of corresponding magnets within the electronic device and the dock 800.

[0064] Referring now to FIG. 8B, the arrangement of the plurality of magnets 802 as shown in FIG. 8A is shown with other components of the dock 800 removed for simplicity. The arrangement of the magnets within the dock 800 is optimized to improve the user experience when docking and undocking the electronic device from the dock 800. The arrangement of the magnets optimally includes an alternating polarity arrangement along the outermost three groups 820 of magnets 802 on the first side 806 and the second side 808 of the longitudinal axis 812, and at least four groups 804 are arranged horizontally as will be described in further detail below. Further, the arrangement of the magnets includes that two vertically oriented groups of magnets 802 (e.g., the fourth group 822) include matching N and S poles across the two groups, as will be described in further detail below. As will be appreciated by those skilled in the art upon reading this disclosure, the arrangement of the plurality of magnets 802 is substantially similar to the arrangement of the plurality of magnets 702 described with respect to FIGS. 7A-7B. Thus, for the same reasons that both the plurality of magnets 802 on the dock and the plurality of magnets on the electronic device (such as the plurality of magnets 702 of the electronic device 700) are optimized to provide improved magnetic coupling and docking between the electronic device and the dock, similar arrangements may be provided.

[0065] As will be described with respect to FIG. 8A, at least four groups 804 of magnets 802 on the first side 806 are mirror configured with respect to at least four groups 804 of magnets 802 on the second side 808, as shown. The mirror configuration advantageously prevents or reduces the occurrence of "false homes" (e.g., when the user brings the electronic device close to the dock, the electronic device is attracted to the wrong magnet on the dock and a false home occurs if the electronic device temporarily shifts with the dock before being centered again).

[0066] According to embodiments described herein, at least three groups (e.g., the outermost three groups 820) on at least the first side 806 and the second side 808 are horizontally oriented and a fourth group 822 is vertically oriented. Orienting the majority of the groups of magnets horizontally on each side of the electronic device provides stability to the system during button presses, particularly when the user is interacting with buttons (such as the volume control button 304 and / or the power button 306 described with respect to FIG. 3A) along the upper edge of the dock 800. When the groups are horizontally oriented, the magnetic strength in the y - direction is increased, and as a result, any tilt resulting from interaction with the upper edge or corners of the electronic device is minimized. The outermost three groups 820 on the first side 806 and the second side 808 include alternating N - and S - poles across the outermost three groups 820 (e.g., from left to right) as indicated by the "N" of the N - polarity. The alternating polarities further prevent the occurrence and misalignment of false homes between the electronic device and the dock by reducing the number of available magnets in the correct orientation close to each other (e.g., such that the magnets attract each other).

[0067] In various embodiments, the two innermost groups 824 of magnets include matching N and S poles across the two innermost groups 824. Said another way, the two innermost groups 824 have the same polarity facing the longitudinal axis 812. This "L-shaped" or "arc-shaped" polarity provides support to the dock 800 when the dock 800 is docked and the user is interacting with buttons along the upper edge of the dock 800 (the volume control button 304 and / or the power button 306 described with respect to FIG. 3A), as will be described with respect to FIG. 7B.

[0068] FIG. 9A shows a side view of a system 900 including an embodiment of an electronic device mounted with an alternative dock design than the dock designs shown in FIGS. 6 and other figures. The dock described with respect to FIGS. 9A-9B operates substantially the same as the other docks described herein, unless otherwise specified, and differs only in size and configuration as detailed herein. The relatively small dock design may be suitable for additional docking stations within the user's home in addition to the main relatively large design docks shown throughout the present invention. In other embodiments, the user may desire a smaller design for any other reason.

[0069] As can be seen from the side view, the electronic device 902 is docked with the dock 904. Region 906 indicates the location where the rear surface 908 of the electronic device 902 contacts the dock 904. Within region 910, a first plurality of magnets are present within the electronic device 602. At corresponding positions within region 906, a second plurality of magnets are present within the dock 904. The magnets are arranged such that when in proximity, the magnets of the electronic device 902 are attracted to the magnets of the dock 904 to assist in correctly positioning, aligning, and holding the dock 904 in the correct position relative to the electronic device 902. In other embodiments, regions 906 and 910 may extend further upward on the dock 904 and / or may extend along the length of the dock 904 that contacts the electronic device 902. For example, regions 906 and 910 may be of any size and may be located at any position on the electronic device 902 and / or the dock 904.

[0070] Referring now to FIG. 9B, a top cross-sectional view of the dock 904 having an arrangement of magnets 920 is shown. The arrangement of magnets 920 may be suitable for magnetically coupling with a group of magnets on the electronic device (such as a group of additional magnets 714 of the electronic device 700). In various embodiments, the arrangement of magnets 920 is arranged in two groups of three as shown. The arrangement of magnets 920 may have a polarity such that it magnetically attracts the corresponding magnets within the electronic device as detailed above. For example, the magnets within the arrangement of magnets 920 are oriented within the dock 904 such that the corresponding magnets within the electronic device have an opposite polarity to the magnets within the arrangement of magnets 920. Such an arrangement enables the arrangement of magnets 920 within the dock 904 to attract the second plurality of magnets of the electronic device. The arrangement and number of the arrangement of magnets 920 may vary. For example, the dock 904 shows an arrangement of six magnets of the arrangement of magnets 920. In other embodiments, any number of magnets may be grouped together. For example, one magnet, three magnets, two pairs of magnets, etc. may form groups within the arrangement. In yet another example, the number of magnets within a group may vary (e.g., one magnet within one group and two magnets within a second group, etc.).

[0071] In some embodiments, any of the magnets described with respect to dock 904 may include a shunt 924 coupled to the magnet to direct the magnetic field associated with one or more magnets. For example, the magnetic field of the magnet must travel at least through the faceplate 922 of dock 904 in order to magnetically couple (e.g., attract) the corresponding magnet on the electronic device. The shunt can be used to further define the direction of the magnetic field to assist in optimizing the magnetic force and the docking / undocking of the electronic device from dock 904. As shown, shunt 924 is coupled to each of the bottommost magnet pairs of the magnet array. The thickness of each shunt may be 1.0 mm. In various embodiments, these magnets are stronger and / or thicker compared to the topmost magnet of the magnet array. For example, in some embodiments, the relatively thick magnet may be 4.0 mm thick. In other embodiments, the relatively thick magnet may be 2.5 mm thick. In comparison, other magnets, such as the magnets located on the corresponding electronic device, may be 0.6 mm thick. For example, since dock 904 is relatively small and has a lower pivot point and center of gravity (making the dock more prone to tipping when the electronic device interacts), stronger magnets are used closer to the bottom surface 926 of dock 904 to enhance the stability of the tablet computer system.

[0072] In various embodiments, the gap is optimized between magnet 920 and the corresponding magnet within the electronic device. When the electronic device is docked to the dock, the gap is in the range of 1.65 mm to 2.5 mm. As described above, the air gap is optimized to further direct and integrate the magnetic force between the corresponding plurality of magnets within the electronic device and dock 904.

[0073] Figure 10 is a flowchart of a method 1000 for docking and undocking an electronic device from a dock. Step 1002 includes providing an electronic device having a first plurality of magnets in proximity to a dock having a second plurality of magnets. The electronic device and the dock can include any of the embodiments described herein, including any of the magnet arrangements described herein. For example, the electronic device can include at least four groups of magnets on each side of the enclosure, and at least four groups of magnets on a first side of the enclosure are mirror configured with at least four groups of magnets on a second side of the enclosure face. Further, at least three of the groups of magnets on each side of the enclosure can be horizontally oriented, and a fourth group of magnets on each side of the enclosure face can be vertically oriented. Further, the three horizontally oriented groups of magnets on each side of the enclosure can include alternating N and S poles across the three groups of magnets across the enclosure from left to right, and the two innermost groups of magnets can include matching N and S poles across the two groups across the enclosure from left to right. As will be appreciated by those skilled in the art upon reading this disclosure, the dock includes a corresponding magnet arrangement having a second plurality of magnets such that the electronic device magnetically couples to the dock. Step 1004 includes magnetically coupling the electronic device to the dock, and the first plurality of magnets align with the second plurality of magnets to dock the electronic device to the dock. Step 1006 can include undocking the electronic device from the dock by applying a force opposite to the magnetic force magnetically coupling the electronic device to the dock. For example, the user can pull and / or pivot the electronic device away from the dock such that the force applied by the user breaks the magnetic coupling that previously secured the electronic device to the dock. In some embodiments, the user pivots the electronic device downward and away from the dock to undock the electronic device from the dock, and when the electronic device disengages from the dock, reduces unwanted tipping of the dock.For example, in some instances, the magnet of the electronic device may remain attracted to the magnet of the dock when the electronic device is pulled away from the dock and may move the dock a short distance along with the electronic device. To counteract these effects, a particular tensioning mechanism and pivot mechanism used by the user may be employed.
