Abstract
The disclosed technology provides an electronic device including an eyepiece and a wireless charging coil forming at least one loop around the eyepiece. The charging coil is coupled to a rechargeable battery and adapted to inductively charge the rechargeable battery when the electronic device is positioned such that the wireless charging coil is within a magnetic field generated by a wireless charging source.
Claims19
A system comprising:
- an electronic wearable device adapted to provide at least one of a virtual reality or an augmented reality experience to a user, the electronic wearable device including:
- optical components including an eyepiece;
- a rechargeable battery;
- and
- a wireless charging coil positioned to form at least one loop around the eyepiece, the wireless charging coil being coupled to the rechargeable battery and adapted to inductively charge the rechargeable battery when the electronic wearable device is positioned such that the wireless charging coil is within a magnetic field generated by a wireless charging source;
- and
- a charging case sized and shaped to store the electronic wearable device, the charging case including a sidewall panel embedding a wireless charging coil, the sidewall panel being substantially parallel to the eyepiece of the electronic wearable device when the electronic wearable device is positioned in a charging configuration within the charging case.
4 more elements
A method comprising:
- positioning an eyepiece of a head-mounted display (HMD) device adjacent to a wireless charging coil in a wireless charger, the HMD device being at least one of an augmented reality or a virtual reality device and including a wireless charging coil forming at least one loop around a perimeter of the eyepiece, wherein the wireless charger includes a sidewall panel embedding a wireless charging coil, the sidewall panel being substantially parallel to the eyepiece of the HMD device when the HMD device is positioned in a charging configuration relative to the wireless charger;
- and
- coupling a power supply to the wireless charger to generate a magnetic field that induces a current in the wireless charging coil around the perimeter of the eyepiece.
A system comprising:
- an HMD device including an eyepiece and a wireless charging coil forming at least one loop around a perimeter of the eyepiece;
- and
- a charging device for charging the HMD device, the charging device including a wireless charging coil embedded within a panel that rests adjacent to the wireless charging coil in the HMD device when the HMD device charging, the panel being substantially parallel to the eyepiece of the HMD device when the HMD device is positioned in a charging configuration relative to the charging device.
