As shown in
This magnetic coupling system can confer several benefits over conventional systems. First, the magnetic coupling system generates a large normal retention force relative to the coupling interface, which can securely retain the first interface relative to the second interface and prevent first interface dislodgment in response to an applied normal force and/or bending moment. Second, the magnetic coupling system enables first interface removal from the second interface in response to application of a relatively small shear force or angular force, relative to the retention force. Third, the magnetic coupling system generates an attractive force, which can provide a user with tactile instructions for proper alignment, orientation, and/or coupling. Fourth, the magnetic coupling system can enable symmetric coupling (e.g., radially or rotationally symmetric coupling, reflection-symmetric coupling, point symmetric coupling etc.), such that the first interface can couple to the second interface in one or more orientations. Fifth, by controlling the radial and/or arcuate placement of the magnetic element sets on the first interface and second interface, the magnetic coupling system can radially align a point on the first interface with a point on the second interface. Sixth, the magnetic coupling system can function to arcuately orient a point on the first interface with a point on the second interface by using patterns of magnetic elements with alternating or opposing polarities. Seventh, by using the patterns of magnetic elements with alternating or opposing polarities 420, the magnetic coupling system can generate a highly concentrated magnetic field, which can function to increase the retention force, reduce electromagnetic interference with adjacent electromagnetic devices (e.g., credit cards), or otherwise influence the cooperatively generated magnetic field.
The magnetic coupling system is preferably operable between a retention mode and removal mode. In the retention mode, the magnetic coupling system can retain the relative coupled position of the first and second interfaces. The magnetic coupling system is preferably operable in the retention mode in response to application of a separation force up to a predetermined force threshold that is applied in a normal direction to the coupling surfaces of the first and second interface, but can alternatively be operable in the retention mode in response to any other suitable applied force. The predetermined force threshold is preferably approximately 1N, but can alternatively be between 0.8N and 2.2N (e.g., between 0.18 lb-force and 0.5 lb-force), or can be any other suitable force. In the removal mode, the first and second interfaces can be decoupled in response to a torsional force (rotational force) applied to the first or second interface in a direction perpendicular to the coupling surface normal vector, in response to relative rotation between the first and second interface, in response to a separation force exceeding the predetermined force threshold, or in response to any other suitable applied force. The minimum torsional force to switch system operation from the retention mode to the removal mode is preferably less than 0.8N, but can alternatively be between 0.8N and 2.2N (e.g., 1N), above 2.2N, or be any other suitable force.
In one variation, the interface is a sub-component of an electronic device, mounting system (e.g., inductive charger, peripheral device, etc.), or any other super-system, but can alternatively be a stand-alone component. In this variation, the interface can be arranged proximal a broad face of the super system (e.g., parallel a broad face of the super system, along a broad face of the super system, etc.), along a side of the super system, along an edge of the super system, or along any other suitable surface of the super system. In a second variation, the interface further defines a first and second broad face, wherein the magnetic elements can be arranged proximal a broad face of the interface (e.g., parallel the broad face of the interface, along the broad face of the super system, etc.), along a side extending between the first and second broad faces of the interface (e.g., as shown in
Each interface preferably includes a set of magnetic elements 402 that function to transiently retain, align, and orient the interfaces. Each interface can additionally include an induction coil 500 or any other suitable component that can benefit from substantially accurate alignment. Each interface preferably defines a coupling surface 204, 304 configured to couple to a complimentary interface. The coupling surface can be substantially planar, curved, or have any other suitable configuration. The coupling surface is preferably substantially smooth, but can alternatively or additionally include gripping features (e.g., traction, rubber, etc.), alignment features, or any other suitable feature. The interface can additionally define a central axis. The interface can include one or more axes of symmetry, but can alternatively be asymmetric. For example, the interface can be reflectionally symmetric, radially symmetric, point symmetric, or otherwise symmetric. In a specific example, the interface can have a substantially round broad face or perimeter, ovular broad face or perimeter, polygonal broad face or perimeter, an asymmetric broad face or perimeter, or any other suitable broad face or perimeter.
The magnetic elements 402 of the magnetic coupling system function to cooperatively generate an electromagnetic coupling force (e.g., an attractive force) that removably retains the first interface (e.g., an electronic device) with the second interface (e.g., a mounting system). The magnetic elements can additionally function to radially align a first reference point of the first interface with a second reference point of the second interface. The magnetic elements can additionally function to arcuately orient a third reference point 208 of the first interface relative to a fourth reference point 308 of the second interface. The first and third reference points and second and fourth reference points can be different or the same. The first and second reference points can be a central interface axis, central component axis such as an induction coil central axis (e.g., coil winding axis, etc.), a keying point on the interface perimeter, an exposed electrode, terminal, or other electrical connection, and/or be any other suitable reference point. The central axis preferably extends along a substantially normal axis to an interface coupling surface, but can alternatively extend at any other suitable angle to the interface coupling surface. The third and fourth reference points can be an axis of symmetry, a point along an interface perimeter, a predetermined display orientation, or any other suitable reference point. In one example, the first and second reference points can be arranged along the body of the interfaces, and the third and fourth reference points can be arranged along a perimeter of the interface.
The magnetic elements are preferably arranged in sets, wherein each set preferably includes a plurality of magnetic elements, but can alternatively include a single magnetic element. Each interface can include one or more sets of magnetic elements. Alternatively, each interface can include a plurality of magnetic elements, wherein the plurality of magnetic elements can be divided into one or more sub-sets. However, the magnetic elements can be otherwise organized into groups 400.
The magnetic elements 402 can be permanent magnets 403, electropermanent magnets 404, electromagnets, or any other suitable ferrous element. The permanent magnet can be made from a soft or hard ferromagnetic material. Examples of permanent magnet materials include iron, nickel, cobalt, rare earth metal alloys, annealed iron, alnico and ferrite, but any other suitable ferromagnetic materials can be used. The electropermanent magnet can include a static magnet, a reversible magnet, and a set of electrical solenoids disposed relative to the reversible magnet (e.g., disposed about the reversible magnet perpendicular to the static or reversible magnet magnetic field direction) and configured to dynamically adjust the reversible magnet polarity. The static magnet can be made of a hard ferromagnetic material (e.g., ferrite) and the reversible magnet can be made of a soft ferromagnetic material (e.g., alnico). However, the static and reversible magnets can be made from any other suitable material. The static and reversible magnets can be arranged such that the respective magnetic fields are oriented in the same direction in a first operating mode, and oriented in different directions in a second operating mode. In the second operating mode, the static and reversible magnets can be arranged with opposing magnetic fields, perpendicular magnetic fields, or magnetic fields in any other suitable pattern. The resultant magnetic field magnitude in the first operation mode is preferably larger than the resultant magnetic field magnitude in the second operation mode, but can alternatively be equal or smaller. The magnetic field magnitude of the static magnet can be larger than, substantially equal to, or smaller than the magnetic field magnitude of the reversible magnet.
The magnetic element strengths (e.g., resultant magnetic field magnitudes) of the magnetic elements can be substantially equal, can vary within a group, can vary between groups of an interface, can vary between interfaces, or can vary in any other suitable manner. The magnetic elements can be selected such that each magnetic element generates an electromagnetic field 180 having a magnitude of less than a tesla (e.g., 12.5 kG), such as on the order of a millitesla (e.g., 5 mT or 50 G), but can alternatively generate a magnetic field having a higher or lower magnitude. Alternatively, the magnetic elements within a group can be selected to have a net electromagnetic field less than a Tesla (e.g., 12.5 kG), such as on the order of a millitesla (e.g., 5 mT or 50 G), but can alternatively be selected to generate a net electromagnetic field having a higher or lower magnitude. The magnet strengths and configuration can additionally be selected to interact with the inductive charger to increase power receipt efficiency, adjust the magnetizing field resulting from charger operation, or otherwise interact with the inductive charger properties. In one variation of the system, the magnetic elements of each group are selected to generate a predetermined resultant coupling force between the first and second interfaces. The predetermined coupling force can be approximately 1N (0.25 pound force), between 0.8N and 2.2N (e.g., between 0.18 lb-force and 0.5 lb-force), or can be any other suitable force.
Each magnetic element group 400 preferably includes an even number of magnetic elements, which can be preferable to reduce the number of potential or partial coupling states, but can alternatively include an odd number of magnetic elements. In one variation, each magnetic element group includes only two magnets. In a second variation, each magnetic element group includes only three magnets. However, the magnetic element groups can include any suitable number of magnetic elements. The magnetic element groups on the same interface preferably have the same number of magnetic elements, but can alternatively include different numbers of magnetic elements. The magnetic element groups on the first and second interfaces preferably have the same number of magnetic elements (e.g., the first and second plurality of magnetic elements both have the same number of magnetic elements), but can alternatively have different numbers of magnetic elements (e.g., the first plurality of magnetic elements has a first number of magnetic elements, and the second plurality of magnetic elements has a second number of magnetic elements different from the first number). However, the groups can include any suitable number of magnetic elements.
The magnetic elements 402 within a group 400 are preferably arranged adjacent each other, but can alternatively be distributed about the interface. The magnetic elements of a group are preferably substantially contiguous with one or more of the other magnetic elements within the group (e.g., physically connected, partially connected, or separated by a small distance on the order of several millimeters or centimeters), but can be separated by a large gap or otherwise arranged. The magnetic elements can be arranged in a series (e.g., a line, with all magnetic elements in the group aligned along a shared axis or chord, a curve, with all magnetic elements in the group aligned along the curve, etc.), in a triangle, square, circle, or in any other suitable configuration. When the magnetic elements are arranged in a series (e.g., as shown in
Each group 400 of magnetic elements 402 (e.g., set, plurality, sub-set, etc.) is preferably arranged with adjacent magnetic elements having misaligned polarities, wherein a first magnetic element can be oriented with the respective magnetic field directed in a direction different from the magnetic field orientation of an adjacent magnetic element. Alternatively, the group can include one or more adjacent magnetic elements with magnetic fields oriented in the same direction (e.g., as shown in
In a first variation, the magnetic elements in a group 400 can be arranged with alternating magnetic fields, wherein each successive magnetic element in the group is arranged with a magnetic field polarity opposing that of the adjacent magnetic element to form an alternating pattern of magnetization (e.g., as shown in
In a second variation, as shown in
A group 400 can be composed of magnetic elements of substantially the same type (e.g., all permanent magnets, all electropermanent magnets, etc.), material, strength and/or any other suitable parameter. In one variation of the system, the group is composed of substantially the same magnetic element arranged in a first and second orientation about a reflection axis to form the alternating polarity pattern. In this variation, the magnetic element is preferably asymmetric in a plane perpendicular to the magnetic field to enable simpler manufacturing and assembly (e.g., as shown in
Alternatively, the group 400 can be composed of magnetic elements of different types, different materials, different strengths, and/or having any other suitable variant parameter. When the group is formed from magnetic elements having different parameters, the different magnetic elements can be evenly distributed about the group or unevenly distributed about the group. In one variation, the relative sizes and/or strength of the magnets in the set preferably decrease with distance away from the center magnet of the set, but can all be the same size or vary in any other suitable manner. In a second variation, a group includes electropermanent magnets substantially evenly interspersed between adjacent permanent magnets. In a third variation, as shown in
The magnetic element groups 400 of the same interface are preferably substantially similar, having similar magnetic element types, arrangements, polarity patterns, numbers of magnetic elements, net magnetic field strength, or any other suitable parameter, but can alternatively be substantially different. In one variation, an interface can include multiple magnetic element groups, wherein each magnetic element group includes the same number of permanent magnets (e.g., two) having the same magnetic strength arranged in the same arrangement (e.g., in a line tangential to a radius extending from the reference point) and polarity pattern (e.g., opposing polarities, with a first magnetic element generating a magnetic field with a first direction arranged on the left, and a second magnetic element generating a magnetic field with a second opposing direction arranged on the right). In this variation, the magnetic element group arrangement on the interface can render the interface radially symmetric (rotationally symmetric, such as when the same polarity pattern direction is used and the groups are evenly arcuately distributed about the reference point), or radially asymmetric (e.g., when unevenly arcuately distributed, when different polarity pattern directions are used, etc.). In a second variation, an interface can include multiple magnetic element groups, wherein each magnetic element group includes the different numbers of permanent magnets (e.g., a first and second group having two and three magnetic elements, respectively) capable of cooperatively generating electromagnetic fields of different strengths and/or directions (e.g., a first and second magnitude in a first and second direction, respectively) arranged in the different arrangements (e.g., wherein the first group is arranged in a line tangential to a radius extending from the reference point and the second group is arranged in a diamond) and polarity pattern (e.g., opposing polarities and a Halbach array, respectively). However, the magnetic element groups of each interface can have any other suitable composition.
The magnetic element groups of each interface can be substantially evenly distributed about the interface coupling surface, or unevenly distributed. The magnetic element groups of each interface can be arranged with the respective common magnetic element axes at the same angle relative to a tangent extending from the reference point, at different angles relative to a tangent extending from the reference point, or in any other suitable configuration. The magnetic element groups of each interface can be positioned at substantially the same radial distance from the reference point, or be positioned at different radial distances from the reference point.
In one example, the magnetic element groups of an interface can be radially opposed along a chord (e.g., diametrically opposed across the reference point), wherein the magnetic element groups can be arranged equidistant from the reference point (e.g., d1) or at different radial distances from the reference point (e.g., d2,d3). In a second example, the magnetic element groups of an interface can be evenly arcuately distributed about the reference point, wherein the magnetic element groups can be arranged equidistant from the reference point or at different radial distances from the reference point. In a third example, the magnetic element groups of an interface can be arranged at an angle to each other, wherein a first magnetic element group is arranged substantially parallel the coupling surface and a second magnetic element group is arranged along a wall extending from the coupling surface. However, the magnetic element groups can be otherwise arranged on the interface. In a specific example of the interface including a coil, the magnetic element groups can be arranged radially outward of the coil, as shown in
As shown in
The magnetic element groups of the first and second interfaces preferably have complimentary patterns, such that one or more magnetic element groups of the first interface cooperatively generates an attractive electromagnetic force with one or more magnetic element groups of the second interface, but can alternatively have different patterns. The magnetic element groups of the first interface preferably cooperatively generates the substantially the same attractive electromagnetic force with each magnetic element group of the second interface, but can alternatively cooperatively generate different attractive and/or repulsive electromagnetic forces between a first and second magnetic element group subset of the second interface.
In one variation of the system as shown in
In a second variation of the system as shown in
In an example of the second variation, the first interface 200 includes a single magnetic element group and the second interface 300 includes a second and third magnetic element group, wherein the second and third magnetic element groups are arranged an equidistant distance away from the second reference point. However, the multiple magnetic element groups can be arranged different distances away from the second reference point or any suitable distance away from the second reference point. The second and third magnetic elements can function as keying or alignment points for the first interface. For example, if the first interface is radially symmetric, the second and third magnetic elements can be arranged at different angular positions. The first interface can couple to the second interface at a first angular position, as defined by the first magnetic element group coupling to the second magnetic element group, and a second angular position, as defined by the first magnetic element group coupling to the third magnetic element group. The second and third magnetic element groups can be diametrically opposed across the reference point (e.g., 180° apart along the second interface), but can alternatively be separated by any other suitable angular distance. This can function to limit or otherwise define the orientations in which the first interface can couple to the second interface, which can be useful if the first or second interface includes an orientation-dependent component, such as a display. In a specific example, if the first interface includes a display operable in a first and second opposing orientation, and the first magnetic element group is statically coupled to a known position relative to the first and second opposing direction, having the second magnetic element group arranged opposing the third magnetic element group can limit the number of coupling orientations to those that align the display with an external reference point (e.g., perpendicular a gravity vector, perpendicular an axis extending between two watch lugs, etc.).
In a second example of the second variation, the first interface 200 includes a first and second magnetic element group radially opposed across the first reference point of the first interface, and the second interface 300 includes a third and fourth magnetic element group radially opposed across the second reference point of the second interface, wherein the first and second magnetic element groups are both each complimentary to the third and fourth magnetic element groups.
In a third variation of the system, as shown in
The magnetic element groups of the first and second interfaces can additionally include one or more shunt plates 420 that function to concentrate or otherwise shape the electromagnetic field generated each magnetic element group (e.g., as shown in
The induction coil 500 of the interface or super system functions to transfer (e.g., send or receive) energy through inductive coupling. The induction coil preferably includes one or more coils wound about a central axis (induction coil axis, winding axis, coil axis). The coil is preferably substantially planar and wound in a coil plane, but can alternatively be wound in a cylinder or otherwise configured. The coil is preferably arranged with the coil plane substantially parallel the coupling surface, but can alternatively be arranged with the coil plane perpendicular the coupling surface or at any other suitable angle relative to the coupling surface. The coil is preferably arranged proximal to the coupling surface, more preferably adjacent the coupling surface (as shown in
The induction coil 500 can be included in the first interface 200, the second interface 300, neither, or both. In the variation wherein the first and second interfaces include an induction coil, the induction coils are preferably tuned to resonate at substantially the same frequency to induce resonant inductive coupling. However, the induction coils can be non-resonant coupled inductors, wherein one or more of the inductive coils can additionally include a magnetic core or any other suitable coupling circuitry.
The induction coil 500 can have any suitable combination of wire gauge, number of windings, length, pitch, material, inductance, resistivity, capacitance, or any other suitable variable. In one specific example, the one or more induction coils can be a copper coil having a 28 mm outer radius, 16 mm inner radius, 19 turns, 0.25 mm sheet thickness, 0.53 mm total thickness, approximately 19 μH inductance (e.g., 18.78 μH), 0.72 ohm resistance, and 16.64 C charge capacity. However, the one or more induction coils can have any suitable combination of variables.
When multiple induction coils 500 are included in the interface or super system, the multiple coils can be substantially similar or different. The multiple coils can have substantially similar or different combinations of coil variables. The multiple coils can be concentric, offset (e.g., as determined by the respective coil axes), arranged in substantially the same plane, arranged in different planes (e.g., layered), or otherwise arranged. Including multiple coils in the interface can function to accommodate different induction coil resonant frequencies, different complimentary coil positions, or have any other suitable functionality. Alternatively, the interface or super system can include a single coil with a variable inductor in series with the coil, or accommodate for different resonance frequencies or arrangements in any other suitable manner.
The induction coil 500 can additionally be electrically connected to a power conversion circuit 520 that functions to convert a first power input to a second power output. In a first variation, the induction coil functions to provide an electromagnetic field. In this variation, the induction coil can additionally include a power adapter electrically connected to the power conversion circuit and configured to accept power from a power source, such as a power grid, renewable energy system (e.g., solar system, fuel cell, etc.) or any other suitable system. The power conversion circuit functions to convert power received by the power adapter into power for the induction coil. In a second variation, the induction coil functions to receive power. In this variation, the power conversion circuit can function to convert power received by the induction coil into power suitable for an electronic device or a power storage device (e.g., battery unit). However, the induction coil can additionally include any other suitable component.
The induction coil 500 can additionally include a flux concentrator 540 (flux intensifier, diverter, controller) that electromagnetically shields super system (e.g., electronic device) electronics (e.g., processing module) from the magnetic flux of the inductive charger, an example of which is shown in
Each interface of the magnetic coupling system 100 can additionally include an alignment mechanism 120 (shear prevention mechanism) that functions to prevent interface misalignment or shear movement relative to the complimentary interface. More preferably, the alignment mechanism prevents interface movement parallel to the coupling surface when coupled to the complimentary interface. The alignment mechanism is preferably substantially static, but can alternatively be operable between an extended and a retracted mode, or operable between any other suitable state. The alignment mechanism is preferably in the retracted mode when the interface is not coupled to the complimentary interface, and is preferably in the extended mode when the interface is coupled to the complimentary interface. The alignment mechanism preferably switches from the retracted mode to the extended mode in response to receipt of an extension force (e.g., an attractive force generated between the alignment mechanism and the complimentary interface, such as a magnetic force), and preferably switches from the extended mode to the retracted mode in response to removal of the extension force (e.g., retracts when a recovery spring force exceeds the attractive magnetic force). In one variation, the alignment mechanism can include a first group of weak magnetic elements that function to align the first interface relative to the second interface, wherein the first interface can additionally include a second group of strong magnetic elements along the coupling surface that function to retain the first and second interfaces (e.g., as shown in
In a specific example of magnetic coupling system use, as shown in
The magnetic coupling system is preferably used to removably couple the electronic device to a mounting system, but can alternatively be used for any other suitable alignment application. The mounting system can be an inductive charger with an induction coil, but can alternatively or additionally be a watch mount including a first and second watch lug, a peripheral device, or any other suitable mounting system. When the mounting system is an inductive charger including an induction coil, the magnetic coupling system functions to substantially coaxially align the induction coil of the electronic device with the induction coil of the induction coil (e.g., within a margin of error, such as several millimeters), such that power transfer efficiency between the two coils can be maximized, optimized, or otherwise increased. Alternatively, the mounting system can substantially align a first and second angular portion of the first and second induction coils, respectively. When the mounting system is a watch mount, the magnetic coupling system can function to angularly align the electronic device with a reference point on the watch mount, such that an axis of a subsequently displayed image can be reliably aligned relative to the watch lugs. When the mounting system is a peripheral device, the magnetic coupling system can function to angularly align an axis of a subsequently displayed image on the electronic device with a reference point on the peripheral device (e.g., a longitudinal axis, gravitational axis, etc.). This can be particularly useful when the electronic device and/or mounting system has one or more axes of symmetry. When the mounting system and electronic device include a first and second electrical connection, respectively, the magnetic coupling system can function to substantially align the first and second electrical connection.
a. Electronic Device.
As shown in
The electronic device can be wirelessly coupled to (e.g., paired with) a portable computing device of the user, wherein the electronic device can receives operation data from the portable computing device. The electronic device can additionally or alternatively be wirelessly or physically connected to an auxiliary device, wherein the auxiliary device can have additional functionalities beyond the capabilities of the electronic device.
The electronic device 600 provides several benefits over conventional second screen systems, such as smartwatches. First, the electronic device is easily decoupled from the user and can be wirelessly charged (e.g., inductive charging without electric contacts, charging through surface contacts, etc.), which facilitates fast and easy recharging. This charging habit is further reinforced by incorporating a secondary functionality, such as streaming music, into the charging docks (the auxiliary devices), which can increase user willingness to remove the electronic device from the mount and place the electronic device on the charging docks. Second, the electronic device functions as a unique user identifier and as a port into the user's portable device (e.g., phone), thereby enabling the user to answer calls, make payments, control connected devices, or control any other suitable portable device functionality without having to take out the portable device. Third, the electronic device is preferably substantially entirely enclosed and lacks ports, such that security is enabled through isolation. Fourth, because the electronic device relies on the portable device for a majority of the electronic device's functionality, the electronic device and portable device pair can function as a two-step verification system. In one variation, the electronic device is preferably inoperable after a threshold period of time after disconnection from the paired portable device. In another variation, the electronic device simply functions as an identifier for the portable device. If the electronic device is beyond a threshold distance of the portable device (e.g., when the electronic device is stolen), the electronic device will be operable, but any auxiliary device connected to the electronic device will not be able to access the portable device.
In use, the user wears the electronic device 600 by coupling the electronic device to the wearable mount, wherein the electronic device functions as a second screen for the computing device. In response to the user coupling the electronic device to the accessory device, the electronic device functions as a user indicator, more preferably as a computing device indicator, to initiate user-preferred functionalities on the accessory device. The user preferably removes the electronic device from the wearable mount to physically couple the electronic device to the accessory device, but can alternatively touch or bring the mounted electronic device proximal the accessory device to digitally couple the electronic device to the accessory device. The electronic device can be charged when physically coupled to the auxiliary device. Data can additionally be communicated between the electronic device and auxiliary device through low-power, short-range communication when the electronic device is physically coupled to the auxiliary device, electrical contact pairs, or through any other suitable data communication means.
The electronic device 600 can be operable between a set of modes, dependent upon whether the electronic device is coupled to a mounting system. The electronic device can additionally be operable between the set of modes based on which mounting system the electronic device is mounted to. The electronic device is preferably operable between at least a standby mode and an active mode, and can additionally be operable in one or more auxiliary modes when the electronic device is connected to an auxiliary device. The electronic device is preferably operable in the standby or active modes when the electronic device is coupled to the mounting system, but can be operable in the standby or active modes when the electronic device is decoupled from the wearable mount or in any other suitable coupling state. The standby mode can include running low-power functionalities, running only the functionalities required to detect an adjustment event, shutting off, or operating in a low-power consumption state relative to the active mode in any other suitable manner. The active mode can include powering the display module, receiving data from the portable device and/or the auxiliary device, recording measurements from the sensors at an increased frequency, sending data (e.g., sensor measurements, etc.) to the portable device and/or auxiliary device, or operating in a high-power consumption state relative to the standby mode. However, the standby and active modes can include running any suitable functionality. The electronic device is preferably switched from the standby mode to the active mode in response to the detection of an adjustment event. The adjustment event is preferably based on sensor measurements, but the electronic device operation mode can alternatively be switched when an adjustment signal is received from the portable device or the auxiliary device. The electronic device operation mode can be switched based on accelerometer measurements, wherein the electronic device is operated in the active mode in response to an accelerometer signal indicative of a normal vector of the electronic device broad face falling within a predetermined angular range of the gravity vector (e.g., when the angle between the normal vector and the gravity vector is less than) 60°. The electronic device operation mode can be switched based on a touch sensor measurement, wherein the electronic device is operated in the active mode in response to a detected touch (e.g., a change in screen capacitance or resistivity, etc.), such as a tap. The electronic device can be operated in the active mode in response to receipt of a predetermined touch pattern (e.g., a pattern of two taps). In one example, the electronic device can include a piezoelectric chip that generates a current that initiates the wakeup sequence in response to an applied force (e.g., a user pressing on the electronic device). The electronic device operation mode can be switched based on transducer measurements, wherein the electronic device is operated in the active mode in response to a transducer signal indicative of a predetermined audio pattern. The audio pattern can be a pattern of audio generated by the user (e.g., whistling), generated by mechanical contact with the electronic device (e.g., tapping), or generated by any other suitable means.
The electronic device 600 can additionally be operable in a different auxiliary operation mode for each different mounting system. The electronic device can automatically determine which mounting system it is connected to based on information or power transfer, or lack thereof, between the mounting system and the electronic device, based on the components (e.g., induction coil only, electrical contact only, induction and electrical coil, etc.) that are electrically coupled to the mounting system, or based on any other suitable mounting system identifier. In one example, the electronic device can be operable in a first auxiliary operation mode in response to electronic device coupling to a first mounting system, operable in a second auxiliary operation mode in response to electronic device coupling to a second mounting system, and operable in a third auxiliary operation mode in response to electronic device coupling to a third mounting system. The first, second, and third mounting systems can be mounting system types (e.g., wearable mount, peripheral device, or charger), or can be individual mounting systems (e.g., a first and second wearable mount, etc.). The standby and active modes can be shared or different across different auxiliary operation modes. In one example, the electronic device can be operable in a first auxiliary operation mode in response to electronic device coupling to a wearable mount (e.g., a watch band), operable in a second auxiliary operation mode in response to electronic device coupling to a charging device, and operable in a third auxiliary operation mode in response to electronic device coupling to a peripheral device, wherein each auxiliary operation mode can be associated with a different set of electronic device functionalities. In this example, the electronic device can function as a smartwatch and/or interface to the personal device in the first auxiliary operation mode, as an electronic device power storage unit state of charge indicator in the second auxiliary operation mode, and as a peripheral device control interface in the third auxiliary operation mode. However, the electronic device can be operable in any other suitable set of operation modes.
The casing 610 (housing) of the electronic device functions to mechanically protect and enclose the electronic device components. The casing can define a first and second opposing broad face and a central axis extending substantially perpendicular the first and second broad face. The first and second broad faces can have the same dimensions or have different dimensions. The first and second broad faces can be rotationally symmetric, reflectionally symmetric, include one or more axes of symmetry, be asymmetric, or have any other suitable symmetry. The first and/or second broad face can be circular, ovular, polygonal, or have any other suitable profile. The casing can be cylindrical, prismatic, pyramidal, spherical, or have any other suitable shape. However, the casing can include any other suitable configuration.
The casing 610 preferably substantially cooperatively encloses all of the electronic device components with the display cover. Alternatively, the electrodes or electronic connectors can extend through the casing, and are preferably flush with the casing exterior but can alternatively protrude or be recessed from the casing. The casing is preferably formed from siding and backing, but can alternatively include a unitary housing, wherein the housing defines the electronic device sides and back face. Alternatively, the casing can include any suitable number of pieces. The casing is preferably metal, but can alternatively be plastic (e.g., polymeric), cloth, stone, wood, carbon fiber, or any other suitable material.
