Abstract

Exemplary embodiments are directed to wireless power transfer including generating an electromagnetic field at a resonant frequency of a transmitter to create a coupling-mode region within a near field of the transmitter during a synchronization portion of a time-multiplexed recurring period. During a power transmission portion of the recurring period, the electromagnetic field will continue to be generated when there is a receiver within the coupling-mode region, or the electromagnetic field will be disabled when there are no receivers within the coupling-mode region. Different segments of the power transmission portion are allocated to different receivers. The transmitter issues serial commands to the receivers by on/off keying the electromagnetic field. The receivers issue serial replies by changing the amount of power consumed from the electromagnetic field between two different states. The serial commands and serial replies are used to determine the number of receivers, their power requirements, and the allocation of segments.
