WIRELESS POWER UTILIZATION IN A LOCAL COMPUTING ENVIRONMENT
First Claim
1. A method of wirelessly transmitting power, comprising:
- at a wireless power supply;
wirelessly passing power from the wireless power supply to a resonant circuit of an external device using a frequency band of the wireless power supply;
receiving an indication from the external device of an amount of power wirelessly received from the wireless power supply; and
causing the resonant circuit of the external device to tune to a different frequency band of the wireless power supply when a different amount of power is required by the external device.

Abstract
Various embodiments of a wirelessly powered local computing environment are described. The wireless powered local computing environment includes at least a near field magnetic resonance (NFMR) power supply arranged to wirelessly provide power to any of a number of suitably configured devices. In the described embodiments, the devices arranged to receive power wirelessly from the NFMR power supply must be located in a region known as the near field that extends no further than a distance D of a few times a characteristic size of the NFMR power supply transmission device. Typically, the distance D can be on the order of 1 meter or so.
