Apparatus and method for full-orientation over-the-air charging in portable electronic devices
First Claim
1. A portable electronic device system for wirelessly charging a portable electronic device, the portable electronic device system comprising:
- a receiver coil associated with the portable electronic device for wireless charging; and
a repeater coil associated with a device selectively configured to engage or support the portable electronic device for wireless charging, wherein the device is one of a cover, holster, or case for the portable electronic device;
wherein the receiver coil occupies two planes with a first portion of the receiver coil in a first plane and a second portion of the receiver coil in a second plane;
wherein the repeater coil occupies two planes with a first portion of the repeater coil in a first plane and a second portion of the repeater coil in a second plane, the second portion of the repeater coil and the second portion of the receiver coil form a magnetic coupling therebetween, and the first portion of the repeater coil and the first portion of the receiver coil having substantially no magnetic coupling therebetween due to a chassis of the portable electronic device; and
wherein, when the device is selectively engaged or supporting the portable electronic device, a portion of the repeater coil overlaps a portion of the receiver coil forming a magnetic coupling therebetween and supporting wireless charging of the portable electronic device in a plurality of orientations of the portable electronic device relative to a transmitter coil.
