DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS
[0030] Various embodiments disclosed herein relate to a battery pack for use with a wearable computing device. The battery pack can be wearable, and can configured to be worn adjacent or near the wearable computing device (e.g., on the same body portion of the user). The battery pack can include a supplemental battery and can be used to provide electrical power to the wearable computing device (e.g., for recharging the battery of the wearable computing device). The user can remove the supplemental battery pack without removing the wearable computing device. The user can continue wearing the wearable computing device while the supplemental battery of the battery pack is recharged (e.g., via a wall outlet). Then the battery can be reattached at a later time (e.g., once the battery of the wearable computing device is low on power) to again provide electrical power to the wearable computing device (e.g., for recharging the battery of the wearable computing device). The supplemental battery pack can function to relay electrical power from a power source (e.g., a wall outlet) to the wearable computing device (e.g., for charging the battery thereof), e.g., without requiring the user to remove the wearable computing device. Thus, the user can wear the wearable computing device for an extended period of time (e.g., days, weeks, months, years) without removing the wearable computing device to recharge the battery. [0031] The user can wear the wearable computing device (e.g., on the user's wrist) with or without the supplemental battery pack. When not in use, the battery pack can be stored (e.g., in a pocket or bag) or can be worn by the user in a manner that is decoupled from the wearable computing device. For example, when not in use, the battery pack can be worn on the wrist (e.g., as a bracelet) of one arm and the wearable computing device can be worn on the wrist (e.g., as a smartwatch) of the other arm. In some cases, the battery pack can be coupled to the wearable computing device when not in use (e.g., worn on the wrist adjacent to the wearable computing device) and the battery pack can be configured to transfer power to the wearable computing device in response to user input (e.g., actuating a button, switch, etc.). In some cases, the user can wear the supplemental battery pack for only a short time (e.g., while the supplemental battery recharges the battery of the wearable computing device). Once the electrical power has been transferred, the user can remove the battery pack.
[0032] Figure 1 shows a battery pack 100 for charging a wearable computing device 102 (e.g. a smartwatch). Figure 1 shows the battery pack 100 and the wearable computing device 102 in a decoupled state. Figure 2 shows the battery pack 100 and the wearable computing device 102 in a coupled state. In some embodiments, the wearable computing device 102 can be a smartwatch, although the wearable computing device 102 can be various other forms of wearable articles such as a necklace, glasses or other eyewear, an earpiece, a ring, an implanted device, etc. The wearable computing device 102 can include a housing 104, which can enclose or support other features of the device 102. The wearable computing device 102 can include one or more output elements (e.g., a display 106) configured to provide information to a user. For example, the display 106 can display images (e.g., text, numbers, pictures, etc.) to convey information to a user. The display 106 can be used to display time information (e.g., numerically or as an image of an analog clock), text messages, email messages, calendar notifications, etc. In some embodiments, the wearable computing device 102 can include a communication interface (e.g., a wireless communication interface) that is configured to send and/or receive information from a different computing device (e.g., a non-wearable computing device such as a cell phone). The display 106 can be supported by the housing 104. In some embodiments, the one or more output elements can include an audio output (e.g., a speaker). [0033] The wearable computing device 102 can include a controller 108, which can include one or more processors (e.g., housed inside the housing). The controller 108 can be configured to provide image data to the display 106 for displaying images. The controller 108 can be in communication with a computer-readable memory module (not shown), which can store algorithms, programs, databases, videos, pictures, etc., which can be executed or used by the controller 108. The processor 108 can run software programs (e.g., apps). The controller 108 can be in communication with the communication interface, which can facilitate communication with another computing device (e.g., a cell phone).
[0034] The wearable computing device 102 can include one or more user input elements 110. In some embodiments, the one or more output elements (e.g., the display 106) and the one or more user input elements 110 can be incorporated into one or more shared elements. For example, the display 106 can be a touchscreen display that is configured to display information to a user and to receive information from the user (e.g., by sensing the user's touch on the display 106). In some embodiments, the one or more user input elements 110 can include one or more physical input elements such as buttons, switches, dials, etc. The user input elements 110 can be in communication with the controller 108, and the controller 108 can be configured to interpret input from the one or more user input elements 110.
[0035] The wearable computing device can include a battery 112, which can provide electrical power to the display 106, the controller 108, and/or other electrical components of the device 102. The battery 112 can be supported by the housing 104 (e.g., enclosed inside the housing 104). In some embodiments, the battery 112 can be a rechargeable battery. The battery 112 can be removable from the housing 104, or permanently coupled to the housing 104. The wearable computing device can include a power input interface 114, which can be electrically coupled to the battery 112. The power input interface 114 can be configured to provide electrical power to the battery 112 (e.g., for recharging the battery). In some embodiments, the power input interface 114 can provide electrical power directly to the controller 108, the display 106, and/or other electrical components of the device 102. The power input interface 104 can include a port configured to physically receive an electrical plug (e.g., micro USB, lightning, etc.). In some embodiments, the power input interface 114 can include a wireless charging interface (e.g., for inductive charging). For example, the power input interface 114 can be configured to provide electrical power (e.g., to the battery 112 or other electrical components of the device 102) when placed in an electromagnetic field (e.g., produced by a corresponding power output interface). In some embodiments, the power input interface 114 can be configured to send and/or receive data as well as electrical power (e.g., via a wire or wireless signal).
[0036] The wearable computing device 102 can include a coupling element 116, which can be configured to couple the wearable computing device 102 to the wearer. For example, in some embodiments in which the device 102 is a smartwatch, the coupling element 116 can be a wrist strap configured to couple the device 102 to the wrist of the wearer. The coupling element 116 can include a cord, chain, lanyard, eyewear frame, headband, ear hook, belt clip, or other wearable element. In some embodiments, the housing 104 and the coupling element 116 can be integrated into a single feature. For example, the housing 104 can have a shape that is configured to couple to a wearer (e.g., a curved shape that fits onto a wrist).
[0037] The battery pack 100 can include a housing 118 (sometimes referred to as a supplemental housing or battery pack housing), which can enclose or otherwise support other components of the battery pack 100. The battery pack 100 can include a battery 120 (sometimes referred to as a supplemental battery). The battery 120 can be inside of, or otherwise supported by, the housing 118. The battery 120 can be a rechargeable battery, in some embodiments. The battery pack 100 can include a power output interface 122, which can transfer electrical power from the battery 120 (e.g., to the wearable computing device 102). The power output interface 122 can include an electrical plug (e.g., micro USB or lightning) that is configured to physically couple with a port to transfer electrical power from the battery 120 to the wearable computing device 102 (e.g., to the battery 112 thereof). In some embodiments, the power output interface 122 can include a wireless charging interface (e.g., for inductive charging). For example, the power output interface 122 can be configured to produce an electromagnetic field that can cause the power input interface 114 to provide electrical power (e.g., to the battery 112). In some embodiments, the power output port 122 can be configured to transfer data (e.g., to the wearable computing device 102). The battery pack 100 can include a power input interface 124, which can be configured to provide electrical power to the battery 120 (e.g., for recharging the battery 120). The power input interface 124 can be similar to the power input interface 114 of the wearable computing device 102. The power input interface 124 of the battery pack 100 can include a port configured to physically receive an electrical plug (e.g., micro USB, lightning, etc.). In some embodiments, the power input interface 124 can include a wireless charging interface (e.g., for inductive charging). For example, the power input interface 124 can be configured to provide electrical power (e.g., to the battery 120) when placed in an electromagnetic field (e.g., produced by a corresponding power output interface). In some embodiments, the power input interface 114 can be configured to send and/or receive data as well as electrical power (e.g., via a wire or wireless signal). In some embodiments, a single port can be used to provide electrical power to the power input interface 124 (e.g., for charging the battery 120) and to output electrical power from the power output interface 122.
[0038] In some embodiments, the battery pack 100 can include a controller 126 (sometimes referred to as a supplemental controller or a battery pack controller). The controller 126 can include one or more processors. The controller 126 can be configured to control the transfer of electrical power to and/or from the battery 120 (e.g., via the power input interface 124 and/or the power output interface 122). In some embodiments, the battery pack can include a user interface 128. The user interface 128 can include one or more user input elements (e.g., one or more buttons, switches, dials, touchscreens, etc.), which can receive user input. In some cases, the controller 126 can be configured to output electrical power from the battery 120 (e.g., via the power output interface 122) in response to user input.
[0039] In some embodiments, the battery pack 100 can include a communication interface 121, which can be configured to send and/or receive information from a different computing device (e.g., the wearable computing device 102 or a non- wearable computing device such as a cell phone). The communication interface 121 can operate via various wireless protocols, such as Bluetooth, Bluetooth lower energy (BLE), Near Field Communication (NFC), Wi-Fi, etc.). The controller 126 can send information to the communication interface 121, and the controller 126 can perform various functions, as described herein. The controller 126 can be in communication with a computer-readable memory module (not shown), which can store algorithms, programs, databases, instructions, etc., which can be used by the controller 126 to implement various methods and features described herein. In some embodiments, the communication interface 121 can communicate to the different computing device via a cable, wire, or electrical connector and port, etc.
[0040] In some embodiments, the controller 126 can send a notification via the communication interface 121 regarding a charge level of the battery 120, such as when the battery 120 is charging and the battery 120 has reached a full charge, or has reached a predetermined charge level (e.g., 50% charged, 75% charged, 90% charged, 95% charged, etc.). Accordingly, the battery pack 100 can be configured to notify a user when the battery 120 is charged. The controller 126 ca send a notification via the communication interface 121 when the battery 120 is being discharged (e.g., when charging the wearable computing device 102) and when the battery 120 has become depleted or when the battery has reached a predetermined charge level (e.g., 50% charged, 25% charged, 10% charged, 5% charged, etc.).
[0041] In some embodiments, the communication interface 121 can be configured to receive (e.g., wirelessly) firmware update data, and the controller 126 can be configured to perform a firmware update using the information received by the communication interface 121. In some embodiments, the battery back 100 can receive data from an external source via the power input interface 124 or via a separate interface not shown in the figures (which can be a USB port, a micro-USB port, or other electrical port, etc.). The data received can be firmware update data, which can be used (e.g., by the controller 126) to implement a firmware update.
[0042] In some embodiments, the communication interface 121 can be used to send information to a remote computing system (e.g., a server or remote database), which can be used to analyze the information, and which can send responsive information to the battery pack 100, to the wearable computing device 102, or to another local device such as a cell phone associated with the wearable computing device 102.
[0043] The battery pack 100 and/or the wearable computing device 102 can store information regarding charging times when the battery pack 100 is used to charge the wearable computing device 102. For example, times when charging is initiated and/or stopped can be stored, times when the battery pack 100 is connected to and/or disconnected from the wearable computing device 102 can be stored. The charging time information can be stored on a computer-readable memory module of the battery pack 100, of the wearable computing device 102, of a local mobile device (e.g., cell phone) associated with the wearable computing device 102, or of a remote computing system. A controller (e.g., controller 126, or controller 108, or a controller of the local mobile device, or a controller of the remote computing system) can be configured to identify patterns in the charging time information. For example, the controller can recognize that a user generally uses the battery pack 100 to start charge the wearable computing device 102 at certain times (e.g., around 7:00 am, such as when waking up, around 6:00 pm, such as when returning home from work, around 11 :00 pm, such as when going to bed, etc.). The controller can identify different patterns for different days of the week, such as different charging patterns during weekend days as compared to week days. Various other patterns in the charging information can be identified by the controller. If the battery pack 100 is not used to charge the wearable computing device 102 during an expected time (e.g., during a window of time identified as a pattern of when charging is generally performed, such as between 6:00 pm and 7:00 pm), a notification can be sent to remind the user to consider using the battery pack 100 to charge the wearable computing device 102. The controller of the battery pack 100, of the wearable computing device 102, of the local mobile device, or of the remote computing system can determine that charging was not initiated during the expected time and can initiate the notification. The notification can be a text message or other notification type, which can be sent to the local mobile device (e.g., cell phone) to the wearable computing device 102 or to the battery pack 100.
[0044] In some embodiments, the battery pack 100 can include charging module 123. The charging module 123 can be configured to provide electrical power to the battery 120 (e.g., to recharge the battery 120), and/or the charging module 123 can be used to relay electrical power to the wearable computing device 102. The charging module 123 can be a wireless charging module configured to receive electrical power wirelessly (e.g., via inductive charging). The charging module 123 can include one or more solar cells configured to use light to produce electrical energy (e.g., for charging the battery 120 and/or for delivery to the wearable computing device 102). The charging module 123 can include a kinetic charging module that is configured use kinetic energy to produce electrical power (e.g., for charging the battery 120 and/or for delivery to the wearable computing device 102). In some embodiments, the charging module 123 can include a thermal charging module that is configured to use thermally energy to produce electrical power (e.g., for charging the battery 120 and/or for delivery to the wearable computing device 102).
[0045] The battery pack 100 can include a coupling element 130, which can be configured to couple the battery pack 100 to the wearer and/or to the wearable computing device 102. In some embodiments, the coupling element 130 of the battery pack 100 can be similar to the coupling element 116 of the wearable computing device 102. In some embodiments in which the wearable computing device 102 is a smartwatch, the coupling element 130 can be a wrist strap configured to couple the battery pack 130 to the wrist of the wearer (e.g., adjacent to the wearable computing device 102). The coupling element 130 can include a chain, lanyard, eyewear frame, headband, ear hook, belt clip, other wearable element, a clip, a snap-fit element, a friction-fit element, or other element configured to removably attach to the device 102. In some embodiments, the housing and the coupling element 130 can be integrated into a single feature. For example, the housing can have a shape that is configured to couple to a wearer (e.g., a curved shape that fits onto a wrist) or that is configured to couple to the wearable computing device 102.
[0046] The battery pack 100 can enable the user to recharge the battery 112 of the wearable computing device 102 without removing the wearable computing device 102. The user can charge the supplemental battery 120 of the battery pack 100 (e.g., via the power input interface 124). For example, the battery pack 100 can be detached from the user and can be coupled to a power outlet or charging station to provide electrical power to the battery 120 via the power input interface 124. The user can wear the wearable computing device 102 while the supplemental battery 120 of the battery pack 100 is charging. In some instances, once the battery 120 is charged, the user can wear the battery pack 100 (either coupled to the device 102 (e.g., Figure 2) or decoupled from the device 102 (Figure 1)), or the user can carry the battery pack 100 (e.g., in a pocket or backpack). When the battery power of the battery 112 becomes low (or when the user otherwise desires to provide supplemental power to the device 102), the user can transfer electrical power from the supplemental battery 120 of the battery pack 100 to the wearable computing device 102 (e.g., to the battery 112). For example, the user can couple the output power interface 122 of the battery pack 100 to the power input interface 114 of the device 102, which can cause electrical power to transfer from the battery pack 100 to the wearable computing device 102. In some cases, the power transfer can occur in response to the coupling of the output power interface 122 of the battery pack 100 to the power input interface 114 of the device 102. In some cases, the power transfer can occur in response to user input received by the user interface 128. For example, the user can wear the battery pack 100 coupled to the device 102 (e.g., as shown in Figure 2), and in some cases the electrical power does not transfer from the battery pack 100 to the device 102 until a user command is received (e.g., via the user interface 128). The user can remove the battery pack 100 while continuing to wear the wearable computing device 102, and the user can recharge the supplemental battery 120 on the battery pack while continuing to wear the wearable computing device 102. The user can continue to use the battery pack 100 to relay electrical charge to the wearable computing device 102 (e.g., to the battery 112) without interrupting the use and/or the wearing of the device 102.
[0047] Figure 3 shows an example embodiment of a battery pack 100 for charging a wearable computing device 102 (e.g. a smartwatch). Figure 3 shows the battery pack 100 and the wearable computing device 102 in a decoupled state. Figure 4 shows the battery pack 100 and the wearable computing device 102 in a coupled state. The example embodiments shown in Figures 3 and 4 can include features similar to those discussed in connection with Figures 1 and 2 (as well as the other embodiments disclosed herein). In some embodiments, the battery pack 100 can be configured to match the wearable computing device 102. For example, the colors, designs, or other aesthetic elements of the battery pack 100 an correspond to the respective colors, designs, or other aesthetic elements of the wearable computing device 102. For example, the housing 104 of coupling element 116 of the device 102 can include a design element 132, and the housing 118 or coupling element 130 of the battery pack 100 can include a corresponding design element 134. When the battery pack 100 is worn adjacent to the device 102 (and/or coupled to the device 102), the two design elements 132 and 134 can combine to form an aggregate design element or can otherwise complement one another. For example, the design element 134 of the battery pack 100 can be an extension of the design element 132 of the device 102, or vice versa.
[0048] The battery pack 100 can have a shape that corresponds to the shape of the wearable computing device 102. For example, the battery pack 100 (e.g., the housing 118 and/or coupling element 130) can include one or more fitting features 136 (e.g., protrusions or indentations) that correspond to features of the wearable computing device 102. For example, the fitting features 136 on the battery pack 100 can interface with the corresponding features on the wearable computing device 102, e.g., such that the battery pack 100 can have the appearance of being a part of the wearable computing device 102. Thus, the wearable battery pack 100 and the wearable computing device 102 can have the appearance of being a single wearable article (e.g., a watch).
[0049] Figure 5 shows an example implementation of a battery pack 100, which can include features similar to, or the same as, the other embodiments disclosed herein. The battery pack 100 can include a user interface 128. The user interface 128 can include user input elements configured to receive input from a user. For example, a user input element 138 (e.g., a stitch or button, etc.) can be configured to receive input from the user, and the controller 126 can be configured to transfer electrical power from the battery 120 (e.g., via the power output interface 122) in response to user input received by the user input element 138. In some embodiments, the battery pack 100 can be configured to transfer electrical power from the battery 120 in response to a connection of the power output interface 122 to a power input interface 114. In some embodiments, the user interface 128 can include user output elements configured to communicate information (e.g., visually) to a user. For example, one or more lights 140a-d can be included and can be used to communication the amount of electrical charge of the battery 120. In some embodiments, the user interface 128 can include a user input element 142 configured to receive input from the user and adjust the user output element based on the user input. For example, the lights 140a-d can illuminate to represent the amount of charge of the battery 120, e.g., in response to a user pressing the button 142. In some embodiments, all the lights 140a-d can light up to indicate that the battery 120 is about fully charged, half the lights 140a-d can light up to indicate that the battery 120 is about half charged, etc. Various embodiments disclosed herein can include a user interface with features similar to, or the same as, the features shown and described in connection with Figure 5.
[0050] In some embodiments, the battery pack 100 can be configured to use one or more removable batteries 120a and 120b. The battery pack 100 can include a battery interface 144 configured to receive the one or more removable batteries 120a and 120b. The battery interface 144 can be configured to enable electrical power to be transferred between a battery 120a or 120b that is coupled to the battery interface 144 and the power output interface 122 and/or the power input interface 124. The battery interface 144 can include an electrical connector 146 configured to electrically connect to a corresponding electrical connector 148a or 148b on the removable battery 120a or 120b so that electrical power can be transferred from the battery 120a or 120b (e.g., to the power output interface 122) and/or to the battery 120a or 120b (e.g., from the power input interface 124). In some embodiments, a lid or other covering can cover the battery interface 144, and can facilitate retention of the battery 120a or 120b in the battery interface 144. In some embodiments, the battery interface 144 and/or the one or more removable batteries 120a and 120b can include engagement features (e.g., snap-fit features, friction-fit features, etc.) that can facilitate the retention of the battery 120a or 120b in the battery interface 144. In some embodiments, the user can remove a battery 120a and replace it with another battery 120b (e.g., when the first battery 120a depletes its charge, malfunctions, or becomes old or defective). For example, a user can have multiple batteries 120a and 120b that can be charged at different times (e.g., in an external charger). In some embodiments, the power input interface 124 can be omitted. For example, the one or more batteries 120a and 120b can be charged separately from the battery pack 100, and a charged battery 120a or 120b can be attached to the battery pack 100 (e.g., to be used to transfer electrical power to the wearable computing device 102).
[0051] In some embodiments, an adapter 150 can be used with the power output interface 122. The adapter 150 can be removably attachable to the battery pack 100 (e.g., to the power output interface 122). The adapter 150 can include an input 152, which can be configured to receive the power output interface 122. The adapter 150 can include an output 154, which can be configured to engage a power input interface 114 on a wearable computing device 102. The input 152 can receive electrical power, and the input 152 can be electrically coupled to the output 154, such that electrical power can be transferred from the input 152 to the output 154, e.g., for transfer to a wearable computing device 102. The adapter 150 can be used to enable the battery pack 100 to provide electrical power to various wearable computing devices 102, which can have various types of interfaces for the respective power input interfaces 114. Although only one adapter 150 is shown, in some embodiments, multiple adapters can be included to enable compatibility with various types of power input interfaces 114. By way of example, the power output interface 122 of the battery pack 100 can be a micro USB interface, and the adapter can include a micro USB input 152 and a lightning output 154. Thus, the battery pack 100 can be used to charge a device 102 having a micro USB input interface or a lightning input interface. Many variations are possible.
[0052] In some embodiments, the power output interface 122 and/or the power input interface 124 can be movable (e.g., between an extended position and a retracted position). Figure 5 shows the power output interface 122 in an extended position. In some embodiments, in the extended position, the power output interface 122 can couple to an interface 114 on a wearable computing device 102. In some embodiments, in the retracted position, the power output interface 122 can be flush with or recessed into the battery pack 100 (e.g., flush with or recessed into the housing 118). In some embodiments, an actuation element 156 can enable the user to move the power output interface 122 from the retracted position to the extended position and/or from the extended position to the retracted position. For example, the actuation element 156 can include a tab, which the user can push or pull to move the power output interface 122 between positions.
[0053] In some embodiments, a covering can be used to cover the retracted power output interface 122 and/or to cover the actuation element 156. For example, when the cover is in place, the cover can hide the power output interface 122 and/or the actuation element 156. In some embodiments, the actuation element 156 can be located at a position that is hidden from view when worn by the user. For example, the actuation element 156 can be on an underside of the battery pack 100 (e.g., facing towards the user's wrist). The covering mentioned above, or a different covering, can cover the power input interface 124 when not in use. Hiding the power input interface 124, the power output interface 122, and/or the actuation element 156 can give the battery pack 100 a simple and aesthetically pleasing appearance. In some embodiments, some or all of the elements of the user interface 128 can also be hidden when not in use. For example, the lights 140a-d can be positioned behind a semi-transparent layer such that the lights 140a-d are visible through the layer when illuminated and not visible through the layer when not illuminated. The input elements 138 and/or 142 can be covered by a movable layer that extends over the input elements 138 and/or 142. For example, for buttons 138 and/or 142, the movable layer can move when the user presses on the area over the button 138 and/or 142 such that the button 138 and/or 142 can be compressed through the covering layer. The covering layer can generally hide the presence of the button 138 and/or 142.
[0054] Various features described in connection with Figure 5 can be implemented in various other embodiments disclosed herein. For example, various other embodiments disclosed herein can include a user interface 128, one or more removable batteries 120a and 120b, a battery interface 144, one or more adapters 150, and/or one or more actuation elements 156 for moving the power input interface 124 and/or the power output interface 122.
[0055] Figure 6 is a perspective view of an example embodiment of a battery pack 100 that is configured to be worn by a user (e.g., on the user's wrist). The battery pack 100 can include a coupling element 130 that is configured to engage a portion of the user's body or clothing. The battery pack 100 can be a bracelet. In some embodiments, the coupling element 130 can include a strap, a clasp, or various other elements for facilitating the coupling of the battery pack 100 to the user.
[0056] Various types of batteries 120 can be used in the battery pack 100. For example, the battery 120 can be a lithium-ion battery, a nickel-cadmium battery, a nickel-metal hydride battery, or various other battery types. The battery 120 can be rechargeable.
