1. A method of wirelessly distributing power, comprising:
- at a wireless power supply, establishing a first power transmission channel with a first accessory device and transmitting power to the first accessory device over the first power transmission channel;
at the wireless power supply, sensing first and second characteristic load factors that are respectively associated with at least the first accessory device and a second accessory device;
at the first accessory device, establishing a second power transmission channel with the second accessory device in response to at least one of the first and second characteristic load factors changing in a manner that indicates that the second accessory device is not able to receive adequate power directly from the wireless power supply; and
at the first accessory device, transmitting power to the second accessory device over the second power transmission channel.

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.

14. A system for wirelessly distributing power, comprising:
-
a wireless power supply; a first accessory device that is coupled to the the wireless power supply over a first power transmission channel and that has power receiving circuitry configured to receive power from the wireless power supply over the first power transmission channel; and a second accessory device that is coupled to the first accessory device over a second power transmission channel, and that has power receiving circuitry configured to receive power over the second power transmission channel in response to a change in a load state associated with at least one of the first and second accessory devices that indicates that the second accessory device is unable to receive adequate power from the wireless power supply. - View Dependent Claims (15, 16)

17. A computing device, comprising:
-
a processor; a wireless power supply; and memory storing instructions that when executed by the processor, cause the wireless power supply to perform the steps of; establishing a first power transmission channel with a first accessory device and transmitting power to the first accessory device over the first power transmission channel; sensing first and second characteristic load factors that are respectively associated with at least the first and second accessory devices; directing the first accessory device to establish a second power transmission channel with the second accessory device in response to detecting a change in at least one of the first and second characteristic load factors that indicates that the second accessory device is unable to receive adequate power directly from the wireless power supply; and directing the first accessory device to wirelessly transmit power to the second accessory device over the second power transmission channel. - View Dependent Claims (18, 19)
