WIRELESS POWER DISTRIBUTION SYSTEM

摘要

A system for transmission of power into a space, comprising one or more transmitters and several portable receivers which can receive power transmitted. Receivers can transmit data back to transmitters regarding their power needs, based on the state of charge of their batteries. A transmission protocol exists whereby each transmitter can detect legitimate receivers within its field of view and transmit a first amount of energy to any such receiver, which may report receiving that energy back to a transmitter, together with data relating to its power needs. Transmitters can deny power transmission to some receivers based on the data received from a reporting receiver. The first amount of energy transmitted may be used to power up a sleeping receiver, before transmission of useful amounts of power, if allowed by the protocol. Other aspects of the transmission protocol relate to the division of available power between requesting receivers.
