SYSTEMS, APPARATUS, AND METHOD FOR A DUAL MODE WIRELESS POWER RECEIVER
First Claim
1. An apparatus for receiving wireless power, the apparatus comprising:
- a first coil configured to wirelessly receive power from a first transmitter configured to generate a first alternating magnetic field having a first frequency; and
a second coil configured to wirelessly receive power from a second transmitter configured to generate a second alternating magnetic field having a second frequency higher than the first frequency, the second coil positioned to enclose the first coil, a first coupling factor between the first coil and a coil of the first transmitter being higher than a second coupling factor between the second coil and a coil of the second transmitter when the first and second coils are positioned within respective charging regions of the first and second transmitters.

Abstract
Systems, methods and apparatus are disclosed for a dual mode wireless power receiver. In accordance with on aspect, an apparatus for receiving wireless power is provided. The apparatus includes a first coil configured to wirelessly receive power from a first transmitter configured to generate a first alternating magnetic field having a first frequency. The apparatus further includes a second coil configured to wirelessly receive power from a second transmitter configured to generate a second alternating magnetic field having a second frequency higher than the first frequency. The second coil is positioned to enclose the first coil. A first coupling factor between the first coil and a coil of the first transmitter is higher than a second coupling factor between the second coil and a coil of the second transmitter when the first and second coils are positioned within respective charging regions of the first and second transmitters.
