Cross Reference to Related Applications

This patent application claims priority from U.S. provisional patent application No. 63/376,753 entitled "electronic charging System (Electronic Charging System)" filed on month 22 of 2022, priority from U.S. non-provisional patent application No. 18/460,367 entitled "electronic charging System (Electronic Charging System)" filed on month 1 of 2023, the entire disclosures of which are hereby incorporated by reference.

Technical Field

The described embodiments relate generally to head-mountable devices. More particularly, the present embodiments relate to head-mountable devices and associated charging devices.

Background

Recent advances in portable computing enable headable devices to provide Augmented Reality (AR) and Virtual Reality (VR) experiences to users. Such head-mountable devices typically include various components such as a display, a bezel, a lens, a battery, a motor, speakers, and other components. These components may operate together to provide an immersive user experience.

The duration and intensity of use of these user experiences may vary, which is related to power consumption. Unfortunately, the longer duration and/or denser use sessions of the head-mountable device may result in charging inconvenience ("on-the-fly" is typically not chargeable). Thus, conventional implementations of the head-mountable device and charging method may inhibit wear of the head-mountable device throughout the day (or even throughout the use session). Accordingly, there is a need for a head-mountable device that can be more used and that has an improved, flexible charging configuration.

The following description is not intended to limit the embodiments to one preferred embodiment. On the contrary, the following description is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the described embodiments as defined by the appended claims.

The following disclosure relates to an apparatus comprising a head-mountable device and an associated charger. In a particular example, an apparatus of the present disclosure includes a wearable charger. For example, the wearable charger disclosed herein may be connected to a battery of the wearable device when the wearable device is worn on a person or clothing of a person. To illustrate, the wearable charger may be directly attached (e.g., clipped) to one or more arms of the wearable device. As another example, the wearable charger may hang (e.g., around the neck of the user) and attach to the wearable device via a lanyard. In yet another example, the wearable charger may include a power device that helps secure the wearable device to an article of clothing (e.g., shirt, pants pocket, etc.) when the wearable device is charged.

The apparatus of the present disclosure also includes a charging cartridge that interfaces with the headset. For example, the charging cartridge may comprise a fully enclosed cartridge that encloses the head-mountable device inside. As another example, the charging cartridge may include a partial cartridge that partially exposes an arm or other portion of the head-mountable device when engaged. These or other cartridges may include rechargeable cartridges having inductive or conductive interfaces.

The apparatus of the present disclosure may also include a charging base, such as a charging station, a wireless charging pad, and the like. The charging dock may similarly expose portions of the head-mountable device to the ambient environment during charging. Likewise, the charging base may include an inductive charging interface or a conductive charging interface.

Other devices are also disclosed herein. For example, the wearable device may be tethered to a non-wearable battery pack or solar panel, as desired.

These and other embodiments are discussed below with reference to fig. 1-12B. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes only and should not be construed as limiting. Further, as used herein, a system, method, article, component, feature, or sub-feature comprising at least one of the first, second, or third options is understood to mean a system, method, article, component, feature, or sub-feature that can comprise one (e.g., only one first, only one second, only one third option) of each listed option, multiple (e.g., two or more first options) of a single listed option, two (e.g., one first and one second option) at the same time, or a combination thereof (e.g., two first and one second option).

Fig. 1 shows a side view of a user wearable system in the form of a head wearable device 100 worn on a user's head 101. The user-wearable system may include any number of Augmented Reality (AR) glasses or Virtual Reality (VR) goggles. In some examples, the head-mountable device can include a display frame 102 that houses a display 104. In particular, the display frame 102 may include a bezel surrounding the display 104. In addition, the display frame 102 may include a nose bridge (where "nose bridge" refers to a frame portion that connects the left and right frame sides of the display frame 102). In some examples, the nose-bridge may include a nose cutout for placement over the nose 118 of the user.

The display 104 may also include one or more optical lenses or a display screen that may be positioned in front of the user's eyes 116. The display 104 may include a display for presenting a virtual reality visualization, an augmented reality visualization, or other suitable visualization.

As additionally shown in fig. 1, the head-mountable device 100 may include an arm 106 (although only a single arm is seen in this view). The arm 106 may be rotatably connected to the display frame 102 and extend distally towards the back of the head during use. The arm 106 is configured to secure the display 104 in a position relative to the user's head 101 (e.g., such that the display 104 remains in front of the user's eyes 116). For example, the arm 106 extends past the user's ear 114. In some examples, the arm 106 may be placed over the user's ear 114 to secure the head-mountable device 100 via friction between the arm 106 and the user's head 101. For example, the arm 106 may apply opposing pressure to the sides of the user's head 101 to secure the head-mountable device 100 to the user's head 101. Optionally, the arms 106 may be connected to each other via straps (not shown) that may press the head-mountable device 100 against the user's head 101.

Further, the head-mountable device 100 may include various components located inside one or more of the arms 106. For example, the head-mountable device 100 may include a battery 108. The battery 108 may include a myriad of different types of batteries or power sources. In practice, the battery 108 may include one or more electrochemical cells having external connections for powering electrical devices or electrical components. For example, in some implementations, the battery 108 includes a lithium ion battery, an alkaline battery, and the like. In a specific example, the battery 108 comprises a rechargeable battery. In other words, the battery 108 may be removable or rechargeable, as desired.

In a particular example, the battery 108 is electrically connected to the processor 110. The processor 110 may execute computer-executable instructions and/or cause various components of the wearable device 100 to perform certain tasks (e.g., cause the display 104 to present certain AR visualizations). The processor 110 may include one or more processors (e.g., a system on a chip, an integrated circuit, a driver, a microcontroller, an application processor, a cross processor, etc.).

Although the present system is described as including a battery, battery 108 is merely one example of a power source. Other power sources may also be used in a similar manner to battery 108. As used herein, the term "power source" refers to any power source that provides power to charge or recharge the head-mountable device 100. For example, the power source may include a fuel cell, a battery cell, a generator, an alternator, a solar energy converter, a motion-based converter (e.g., that converts vibration or oscillation into electricity), and so forth. In particular implementations, the power source may convert alternating current to direct current (or vice versa) for charging or recharging the head-mountable device 100. Some specific examples of power supplies may include switched mode power supplies, uninterruptible power supplies, alternating current power supplies, direct current power supplies, regulated power supplies, programmable power supplies, computer power supplies, and linear power supplies. For ease of explanation, the present system will be described in the context of battery 108 as the power source.

The head-mountable device 100 may also include other components. For example, the head mountable device 100 may include a microphone, speaker, printed circuit board, or the like. In some implementations, the head-mountable device 100 includes a speaker 112. Speaker 112 may generate audible sound or vibratory sound (via bone conduction). In at least some examples, speaker 112 may include a magnet that may be used in certain charging configurations discussed below with respect to subsequent figures.

The display frame 102 and the arms 106 may comprise a variety of different materials. In some examples, the display frame 102 and arms 106 may include rigid materials (e.g., metal) to provide increased support, protect certain internal components from undesirable stresses or strains, and the like. Additionally or alternatively, the display frame 102 and arms 106 may include a flexible softer material (e.g., silicone) to provide enhanced flexibility and comfort, particularly at areas that are easily contacted by a person's head.

Any of the features, components, and/or parts illustrated in fig. 1 (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts illustrated in other figures described herein. Likewise, any of the features, components, and/or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included in the examples of apparatus, features, components, and parts shown in fig. 1, alone or in any combination. The following sections discuss various aspects of the power devices mentioned above. Specifically, fig. 2 shows a schematic diagram of an apparatus 200 including a head-mountable device 100 and a power device 202 according to one or more examples of the present disclosure.

As shown in fig. 2, a power device 202 is connected to the head-mountable device 100 via a power connection 204. As used herein, the term "electrical connector" refers to an electrical connector. In particular, the power connection may include a wired or wireless charging interface (e.g., a coupling) that allows power to be transferred from the power device 202 to the head-mountable device 100. For example, the power connection may include a conductive connection (e.g., an electromechanical connection with mating pins, plugs, receptacle connectors, or other suitable conductive mechanical contacts). In addition, exemplary components of the power connection include switches, relays, diodes, transistors, resistors, capacitors, transformers, amplifiers, fuses, inductors, potentiometers, and the like. However, in other examples, the power connection may include an inductive connection (e.g., that provides power transfer via induction).

The power connection 204 is schematically shown. Thus, the power connection 204 may include a myriad of different locations for interfacing the headset 100 and the power device 202. In practice, the power connection 204 may connect the power device 202 and the display frame 102 (e.g., at the nose-bridge 212). In another example, the power connection 204 may connect at least one of the arm 106 and the power device 202. In these or other examples, in particular, the power connection 204 may electrically couple the power device 202 with the battery 108.

Further illustrated, the power device 202 may include a variety of different types of devices. For example, the power device 202 may include at least one of a charging cartridge 206, a charging base 208, or a wearable power device 210. As used herein, the terms "charging cartridge," "cartridge," or "rechargeable cartridge" refer to a housing (e.g., a portion of a housing) that is sized and shaped to receive and provide power to a portion of the head-mountable device 100. Some specific examples of the charging cartridge 206 are described below with reference to fig. 7, 8A-8D, and 10.

The power device 202 may also include a charging dock 208. As used herein, the term "charging dock" refers to at least one of a designated charging area or client device that may provide power or share power. One example of a designated charging area includes a wireless charging pad, cradle, or mount, which is generally compatible with a desk, vehicle console, or the like. Some examples of client devices include smart phones, tablets, smart televisions, desktop computers, laptop computers, virtual reality devices, augmented reality devices, smart watches, sound/speaker devices, camera devices, or other computing devices. In these examples or other examples, the charging base provides power to the headset 100 when the headset 100 is positioned in close proximity to or in direct contact with the charging base 208. Some specific examples of the charging base 208 are described below with respect to fig. 11-12B.

The power device 202 may also include a wearable power device 210. As used herein, the term "wearable device" or "wearable power device" refers to a portable battery pack that can be attached to the wearable device 100 when worn (e.g., when worn on the user's head or attached to clothing). Thus, the wearable power device is compatible with the wearable device 100 when positioned in front of the user's eyes, when placed on top of the user's head (or cap), or when hung on a shirt collar, pants pocket, to name a few. Some specific implementations of the wearable power device are described below with respect to fig. 4-6B.

The power device 202 may also include other types of devices not explicitly shown. For example, the power device 202 may include a non-wearable device, such as a battery or other charging brick that may be too large or heavy to be worn. One particular implementation of such a device includes a battery tray and a tether (described below with respect to fig. 9).

Any of the features, components, and/or parts illustrated in fig. 2 (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts illustrated in other figures described herein. Likewise, any of the features, components, and/or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included in the examples of apparatus, features, components, and parts shown in fig. 2, alone or in any combination. The following section discusses the exemplary charging interface mentioned above. Specifically, fig. 3 illustrates an example of a head-mountable device 100 including an example conductive charging interface in accordance with one or more examples of the present disclosure.

As shown in fig. 3, the head mountable device 100 may include a nose bridge interface 302. The nose bridge interface 302 may be positioned between the lenses of the display (e.g., at an intermediate portion of the head-mountable device 100). Additionally, the head-mountable device 100 can include a temple interface 304. The temple interface 304 is positioned between an arm tip 310 (e.g., an end portion) and an arm hinge 312 that mates the arm 106 with the display frame 102. The temple interface may correspond to an anatomical region between the eyes and ears of a human head.

The head-mountable device 100 can also include an arm tip interface 306 positioned at the arm tip 310. Additionally or alternatively, the head-mountable device can include a hinge interface 308 positioned at an arm hinge 312.

In some examples, the head-mountable device 100 may include each of the aforementioned charging interfaces, only a single charging interface, or a particular combination of charging interfaces selected from the aforementioned charging interfaces. Additionally, one or more of the foregoing charging interfaces may flexibly provide a variety of implementations (as will be further explained below) to the power devices of the present disclosure.

Any of the features, components, and/or parts illustrated in fig. 3, including the arrangement and configuration thereof, may be included alone or in any combination in any other examples of devices, features, components, and parts illustrated in the other figures described herein. Likewise, any of the features, components, and/or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included in the examples of apparatus, features, components, and parts shown in fig. 3, alone or in any combination.

Various examples of wearable power devices are described below with respect to the sections of fig. 4-6B. In particular, fig. 4 illustrates an apparatus 400 including a head-mountable device 100 and a wearable power device according to one or more examples of the present disclosure.

As shown in fig. 4, the wearable power device includes a rechargeable battery 404 coupled to the arm tip 310 of the arm 106. In some examples, the rechargeable battery 404 may be positioned against the neck or the back of the user's head (or against longer hair). In these examples or other examples, the rechargeable battery 404 may include a pad (e.g., a cushion, a heat shield pad, etc.) for enhancing the comfort of the rechargeable battery 404 against the user's skin. In this way, the rechargeable battery 404 may be worn when the head-mountable device 100 is in use or worn on the head of a user.

To facilitate such a wearable configuration, the rechargeable battery 404 is coupled to the arm tip 310 or substantially the arm tip region of the arm 106 via the power connection 406 and the lanyard 408. In some examples, the power connection 406 includes an electromechanical connection (e.g., a magnetic connection, a spring needle connection). Additionally or alternatively, the power connection 406 is removably attached to the arm tip 310 of the arm 106. For example, the power connection 406 may include a clasp, hook, or other locking mechanism to secure the lanyard 408 and rechargeable battery 404 to the head-mountable device 100.

Power may be routed along one or more wires disposed inside lanyard 408. Different gauges may provide different levels and/or rates of power transfer. Further, in some examples, lanyard 408 is shielded (e.g., thermally shielded for comfort).

In at least some examples, lanyard 408 may be adjustable. For example, lanyard 408 may be loosened or tightened to adjust the position of rechargeable battery 404. As another example, lanyard 408 may be adjusted to provide different levels of tightness and/or accommodate different head sizes. In yet another example, lanyard 408 can include an outer sheath defining a different color or aesthetic design, as desired.

Any of the features, components, and/or parts illustrated in fig. 4 (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts illustrated in the other figures described herein. Likewise, any of the features, components, and/or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included in the examples of apparatus, features, components, and parts shown in fig. 4, alone or in any combination. Additional details of the head-mountable device and associated power devices are provided below with reference to fig. 5.

Fig. 5 illustrates an apparatus 500 including a wearable device 100 and a wearable power device 502 in accordance with one or more embodiments of the present disclosure. As shown, the wearable power device 502 includes a rechargeable battery that may be attached to the arm 106 at each arm tip 310. In particular, an attachable battery (i.e., wearable power device 502) may be attached to the power connection at each arm tip 310. For example, the attachable battery may be attached to the power connection at the arm tip 310 via a clip attachment, a magnetic attachment, a press fit attachment, an interlocking attachment, or the like. In turn, the attachable battery may be detached from the power connection at the arm tip 310 via a pulling motion, a twisting motion, a combination of push and pull motions, a button press, or other suitable release method.

In some examples, wearable power device 502 is lightweight and ergonomic (may be positioned adjacent or abutting skin behind a user's ear). Additionally or alternatively, the wearable power device 502 is shaped or contoured to follow the contour of the arm tip 310. In some implementations, the wearable power device 502 may also avoid pressure points against the user's head. For example, the orientation or shape of the wearable power device 502 relative to the arm tip 310 may be set such that the wearable power device 502 is positioned parallel to the user's head or away from the user's head (rather than inward and toward the user's head to create a pressure point). In these examples or other examples, arm tip 310 may be flexible to also help avoid pressure points at wearable power device 502.

In some examples, although not shown, the wearable power device 502 is connected to a single arm 106 (rather than to two arms 106 as discussed above). In this case, a single clip-on battery as the wearable power device 502 may power a single HMD battery in the corresponding arm or multiple HMD batteries in the entire wearable device 100 (including an additional HMD battery in another arm 106 without the wearable power device 502).

In other alternative embodiments, wearable power device 502 may be connected with any charging interface or power connection of the present disclosure. For example, the wearable power device 502 may be connected to at least one of a nose-bridge interface, a temple interface, an arm hinge interface, etc., in the same or similar manner as discussed above.

Any of the features, components, and/or parts illustrated in fig. 5, including the arrangement and configuration thereof, may be included alone or in any combination in any other examples of devices, features, components, and parts illustrated in the other figures described herein. Likewise, any of the features, components, and/or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included in the examples of apparatus, features, components, and parts shown in fig. 5, alone or in any combination. Additional examples of a head mountable device with an associated power device are provided below with reference to fig. 6A-6B.

Fig. 6A-6B illustrate an apparatus 600 including a head-mountable device 100 and a power device 604 according to one or more examples of the present disclosure. As shown in fig. 6A, the device 600 is worn on a garment 602, i.e., starting from the collar of a shirt. However, the configuration of such a wearable device 600 may be modified as desired. For example, the device 600 may be worn on a cap or clipped to a pants pocket or waistband. As another example, the device 600 may not be worn on a person (e.g., on a backpack, briefcase, or purse). In this manner, the apparatus 600 may provide a convenient way to charge the headset 100 for further (e.g., throughout the day) use during an outage or session suspension.

In these examples or other examples, the device 600 may be positionally secured to the garment 602 (e.g., without falling or sliding off the garment 602). To this end, the apparatus 600 implements a specific fixed configuration that exploits the arm foldability of the head-mountable device 100. Specifically, as shown in fig. 6B, the power device 604 may be connected to a nose bridge interface of the head-mountable device 100, thereby mounting the power device 604 to the head-mountable device 100 in a charged state. In turn, one of the arms 106 may fold toward the head-mountable device 100 and against the power device 604. In so doing, the magnets 606 positioned on or within the arm 106 may mate with the magnets 608 positioned on or within the power device 604. Once the magnets 606 and 608 are mated to each other, the garment 602 is secured between the mated magnets. Thus, when the head-mountable device 100 is worn on the garment 602, the power device 604 can conveniently charge the head-mountable device 100.

In an alternative example, the power device 604 is connected with a power connection rather than at a nose bridge. For example, when folded against the power device 604, the power device 604 connects with a power connection in the arm 106. In some implementations, the power device 604 can be anchored to the nose bridge of the head-mountable device 100 (e.g., for additional support or rigidity) via corresponding magnets. Additionally or alternatively, the arms 106 may include corresponding magnets to secure the garment 602 between the arms 106.

Any of the features, components, and/or parts illustrated in fig. 6A, including the arrangement and configuration thereof, may be included alone or in any combination in any other examples of the devices, features, components, and parts illustrated in the other figures described herein. Likewise, any of the features, components, and/or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included in the examples of devices, features, components, and parts shown in fig. 6B, alone or in any combination. Examples of the charging cartridge are provided below with reference to fig. 7 to 8D.

Various exemplary charging cartridges are discussed below with respect to the description of fig. 7-8D. In particular, fig. 7 illustrates an apparatus 700 including a head-mountable device 100 and a rechargeable power device 702 according to one or more examples of the present disclosure.

As shown, the rechargeable power appliance includes a charging cartridge, i.e., rechargeable cartridge 702. In some examples, the rechargeable cartridge 702 is a fully enclosed charging cartridge that is sized and shaped to completely enclose the wearable device 100 when inserted therein. Further, in some examples, the rechargeable cartridge 702 includes a charging interface 704 located inside the housing of the rechargeable cartridge 702. For example, the charging interface 704 may include a conductive charging interface, such as a nose-bridge interface, an arm hinge interface, or an arm tip interface.

Additionally shown, the rechargeable cartridge 702 may be recharged via the power connection 706. In some examples, the power connection 706 may couple a power source (e.g., 120Vac wall outlet, battery, etc.) to the charging interface 704 of the rechargeable cartridge 702.

Any of the features, components, and/or parts illustrated in fig. 7 (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts illustrated in the other figures described herein. Likewise, any of the features, components, and/or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included in the examples of apparatus, features, components, and parts shown in fig. 7, alone or in any combination.

The following description discusses other types of charging cartridges, including partially enclosed charging cartridges that expose the head-mountable device at least partially to the ambient environment. In particular, fig. 8A-8D illustrate examples of an apparatus 800 including a power device 802 and a head-mountable device 100 according to one or more examples of the present disclosure.

As shown, the apparatus 800 includes a power device 802. The power device 802 may include a rechargeable power device configured to repeat charge and discharge cycles. The power device 802 may also include a charging interface 804. In some examples, the charging interface 804 is positioned within an interior portion 806 that includes an interior volume defined by an interior cover surface of the power device 802. For example, the charging interface 804 includes a conductive charging interface or an inductive charging interface positioned within the interior portion 806. In a particular implementation, the charging interface 804 may be engaged with the nose-bridge 212 of the head-mountable device 100 (e.g., for power transfer via conductive contacts). In alternative implementations, the charging interface 804 may be engaged with one or more charging coils disposed within the head-mountable device 100 (e.g., for power transfer via induction). An exemplary charging coil is discussed more below with respect to fig. 12A-12B.

In some examples, the power device 802 at least partially covers the display frame 102 and the display 104 within the interior portion 806. In some examples, the power device 802 completely covers the display frame 102 and the display 104 (and not other portions of the head-mountable device 100) within the interior portion 806. For example, the power device 802 may completely encase the display frame 102 and the display 104.

Additionally, in some examples, the power device 802 includes a side through which the arm 106 of the head-mountable device 100 can extend from the interior portion 806 and fold back against the exterior portion 808 of the power device 802. In some implementations (as shown in fig. 8A-8D), the sides of the power device 802 are fully open (allowing the head-mountable device 100 to slide in and out of the power device 802). In this exemplary implementation, the arms 106 extend from the inner portion 806 through the open side of the power device 802. In other implementations, the sides of the power device 802 include holes, apertures, or slots sized and shaped for the arms 106 to be inserted through and extend from the inner portion 806.

Fig. 8C-8D illustrate alternative examples of charging interfaces for the power device 802. In particular, fig. 8C-8D illustrate that the power device 802 includes a charging interface positioned on the outer portion 808. In fig. 8C, a charging interface 810 is positioned across the back of the power device 802 along the outer portion 808. In some examples, the charging interface 810 includes a single power connection (e.g., a conductive power connection). In a particular example, a single power connection is centered laterally across the charging interface 810 such that any of the arms 106 may engage the charging interface 810. In other examples, charging interface 810 includes symmetrical power connections across charging interface 810 (e.g., a left side connection for a left arm and a right side connection for a right arm). Thus, the charging interface 810 may engage any of the arms 106, depending on which arm 106 is folded first. Further, in other examples, multiple power connections of the charging interface 810 may engage a single arm (e.g., at an arm tip interface and a temple interface).

Similarly, fig. 8D shows that the power device 802 includes a charging interface 812. Unlike the single charging interface 810 in fig. 8C, the charging interface 812 of fig. 8D is symmetrically positioned along the exterior portion 808 of the back side of the power device 802. Each of the charging interfaces 812 may include a power connection (whether conductive or inductive) to engage a first or second one of the arms 106, depending on which arm is folded first. In some cases, both charging interfaces 812 engage a single arm 106 (e.g., at an arm tip interface and a temple interface). In other implementations, only one of the charging interfaces 812 engages a single arm 106 (e.g., a left-side connection for a left arm and a right-side connection for a right arm).

In these examples, or other examples, the power device 802 just described with respect to fig. 8A-8D may include a variety of different materials. In some examples, the power device 802 includes a rigid material. In one example, the power device 802 includes a flexible soft material (e.g., silicone). In a particular example, the power device 802 includes a combination of both rigid and soft materials. For example, the power device 802 may be rigid at an area corresponding to the display 104 (e.g., to protect the display 104). In another example, the power device may be rigid (e.g., to support a battery and/or conductive contacts) at an area corresponding to the charging interface. Additionally or alternatively, other areas of the power device 802 may be flexible (e.g., to facilitate easy storage or bagging of the apparatus 800).

Any of the features, components, and/or parts illustrated in fig. 8A-8D (including arrangements and configurations thereof) may be included in any other example of a device, feature, component, and part illustrated in other figures described herein, alone or in any combination. Likewise, any of the features, components, and/or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included in the examples of apparatus, features, components, and parts shown in fig. 8A-8D, alone or in any combination.

The following section discusses tethered power devices for charging the head-mountable device 100. In particular, fig. 9 illustrates an apparatus 900 including a head-mountable device 100 and a power device 902 according to one or more examples of the present disclosure. In some implementations, the power device 902 includes a rechargeable battery pack. In other implementations, the power device 902 includes a portable solar panel.

As shown, the power device 902 is coupled to the head-mountable device 100 via a power connection 904 (e.g., at the arm tip 310 of the arm 106). The power connection 904 may include a variety of different connections (whether conductive or inductive), as described above. For example, the power connection 904 may include a lightning connection, a micro USB connection, or a USB-C connection. In some examples, the power device 902 is electrically coupled to the power connection 904 via the tether 906. In some examples, the length of the tether 906 is adjustable. The tether 906 may also include a variety of different gauge wires (e.g., for different types of power connections or power transfer rates to the head-mountable device 100).

Any of the features, components, and/or parts illustrated in fig. 9, including the arrangement and configuration thereof, may be included alone or in any combination in any other examples of the devices, features, components, and parts illustrated in the other figures described herein. Likewise, any of the features, components, and/or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included in the examples of apparatus, features, components, and parts shown in fig. 9, alone or in any combination.

The following section discusses a wearable device having a detachable portion that can be charged in a charging device. In particular, fig. 10 illustrates a head-mountable device 1000 including a detachable portion 1002 according to one or more examples of the present disclosure. The head-mountable device 1000 is similar to the head-mountable device 100 discussed above, except that the head-mountable device 1000 includes a variation of the arm 106 having a detachable portion (i.e., detachable portion 1002).

In a particular example, the detachable portion 1002 includes a segment of the arm 106 that is removably attachable with respect to the head-mountable device 1000. For example, detachable portion 1002 may include an arm tip that is removable from and reattachable to the head-mountable device 1000. To illustrate, the detachable portion 1002 may be detachably attached to the arm 106 via a magnetic connection, an interlocking connection, an electromechanical connection, or the like.

As shown, the detachable portion 1002 may be detached from the arms 106 and inserted into a charging device 1004 that is sized and shaped to receive at least one of the arms 106. In some examples, charging device 1004 includes a rechargeable cartridge. For example, charging device 1004 includes a charging interface 1006 that is positioned inside charging device 1004 to transfer power from the rechargeable cartridge battery of charging device 1004 to the arm battery (i.e., battery 108) in arm 106. Additionally or alternatively, charging device 1004 includes a charging interface 1006 that is positioned inside charging device 1004 to transfer power from a power source (such as a 120Vac wall outlet connected to charging device 1004) to an arm battery (i.e., battery 108) in arm 106. Thus, charging device 1004 may include one or more power ports for connecting to a power source that may charge, recharge, or otherwise power charging device 1004. In some implementations, the charging device 1004 may include a battery (e.g., a rechargeable battery) disposed within the body of the charging device 1004 that may charge the removable section 1002 without being connected to an external power source. The battery may be connected to a charging interface 1006. In these examples or other examples, the charging interface 1006 is an inductive interface or a conductive interface.

In some examples, a single detachable portion 1002 may be charged in charging device 1004. In other examples, both removable portions 1002 may be charged (e.g., simultaneously charged) in charging device 1004. In these examples or other examples, additional removable portions (e.g., charged removable portions) may be exchanged or interchanged with removable portions that require charging. For example, a third detachable portion may be attached to one of the arms 106 to replace the first detachable portion with a depleted battery. The third detachable portion may include a rechargeable battery that may power the head-mountable device 1000. In some examples, the third detachable portion may be operable to power the head-mountable device 1000, although the second detachable portion (which is still attached to the head-mountable device 1000) also includes a depleted battery. In other examples, the operation of the head-mountable device 1000 requires two functional batteries (i.e., battery 108 in each detachable portion 1002). In this way, the battery 108 in the detachable portion 1002 may be charged in a flexible, convenient manner, which may facilitate wearing the wearable head-mounted device 1000 for a longer duration.

It will be appreciated by those of ordinary skill in the art that the one or more removable portions 1002 need not have a battery 108. For example, the detachable portion 1002 may include different types of arm tips to address ergonomic solutions. To illustrate, removable portion 1002 may be exchanged for other removable portions having foam, gel, or other desired materials (e.g., to increase comfort). As another example, removable portion 1002 may be exchanged for other removable portions having different contours, levels of bending, or stiffness, etc. (e.g., to fit different head sizes).

Any of the features, components, and/or parts illustrated in fig. 10 (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts illustrated in the other figures described herein. Likewise, any of the features, components, and/or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included in the examples of apparatus, features, components, and parts shown in fig. 10, alone or in any combination.

The following section discusses various examples of power devices including a charging dock. In particular, fig. 11 illustrates an apparatus 1100 including a head-mountable device 100 and a charging dock 1102 according to one or more examples of the present disclosure.

As used herein, the term "charging dock" refers to a docking station, a wireless charging pad, a mobile telephone device, a tablet computer, or a notebook computer. In particular implementations, the charging dock includes a structure, platform, or port that can house at least a portion of the head-mountable device 100. In some examples, the charging base (such as a wireless charging pad or docking station) is not itself rechargeable, but is directly connected to a power source, such as a 120Vac wall outlet. In other examples, the charging dock is rechargeable and corresponds to a device that shares or obtains power, such as a mobile phone device, tablet, or notebook. As described above, the charging dock may also provide power to the headset 100 via a conductive charging interface or an inductive charging interface.

As shown, the charging base 1102 includes a docking station in the form of a charging cradle. In a particular implementation, the charging base 1102 includes a conductive charging interface. For example, the charging dock 1102 includes a nose-bridge interface that interfaces with the nose-bridge of the head-mountable device 100.

Although portable, the charging dock 1102 may be configured to sit on a table or other suitable surface (e.g., for direct insertion into a power source). By utilizing a direct power source, the charging dock 1102 is always ready to charge the headset 100. In at least some examples, the charging base 1102 includes a battery (e.g., a rechargeable battery) in electrical communication with the charging coil and/or the power port.

Any of the features, components, and/or parts illustrated in fig. 11 (including arrangements and configurations thereof) may be included alone or in any combination in any other examples of devices, features, components, and parts illustrated in the other figures described herein. Likewise, any of the features, components, and/or parts shown or described with reference to other figures (including arrangements and configurations thereof) may be included in the examples of apparatus, features, components, and parts shown in fig. 11, alone or in any combination.

In contrast, fig. 12A-12B illustrate a head-mountable device 1200 with a charging coil 1202 for implementation with an inductive power device according to one or more examples of the present disclosure. As shown, the head mountable device 1200 includes a charging coil 1202. In some examples, the charging coil 1202 is disposed on the head-mountable device 1200 (e.g., at least partially above a frame surface or display surface). In other examples, the charging coil 1202 is disposed within the head-mountable device 1200 (e.g., subsurface). In certain embodiments, the charging coil 1202 is positioned within the display 104. Additionally or alternatively, the charging coil 1202 is positioned within the display frame 102 and outside of the display 104. In certain implementations, the charging coil 1202 is not visible to the unaided human eye.

As used herein, the "unaided human eye" is the naked eye of an average human observer with normal vision and is not enhanced or supplemented by lenses, microscopes, cameras, or other sight glasses or equipment for distinguishing physical substances outside of the natural human eye.

In these examples or other examples, the charging coil 1202 may include a wire of multiple materials. For example, the charging coil 1202 may include wires formed from copper, aluminum, nickel, steel, brass, iron, graphite, carbon, silicon carbide, or suitable combinations thereof.

Further, it will be appreciated by those of ordinary skill in the art that the charging coil 1202 may include additional wiring and/or electrical components to electrically connect to an HMD battery (e.g., battery 108, not shown). Additionally or alternatively, the charging coil 1202 includes additional wiring and/or electrical components, such as multiple coils and/or multiple winding layers, as desired.

As shown in fig. 12B, the apparatus 1204 includes a head mountable device 1200 and an inductive charging base 1206. The inductive charging base 1206 may include one or more charging coils 1208 positioned parallel (and in close proximity) to the charging coils 1202. For example, when the headset 1200 is mounted on the inductive charging base 1206, one or more charging coils 1208 of the inductive charging base 1206 may be positioned within about 1mm to about 30mm of the charging coils 1202. The inductive charging base 1206 may then generate an alternating electromagnetic field via one or more charging coils 1208. In turn, the charging base 1206 may inductively transfer energy to the charging coil 1202 in the head-mountable device 1200.

Further, while portable, the inductive charging dock 1206 may be configured to sit on a table or other suitable surface (e.g., for direct insertion into a power supply). By utilizing direct power, the inductive charging base 1206 is always ready to charge the headset 1200.

Any of the features, components, and/or parts illustrated in fig. 12A-12B (including arrangements and configurations thereof) may be included in any other example of a device, feature, component, and part illustrated in other figures described herein, alone or in any combination. Likewise, any of the features, components, and/or parts shown or described with reference to other figures (including their arrangement and configuration) may be included in the examples of devices, features, components, and parts shown in fig. 12A-12B, alone or in any combination.
