Receive and Transmit Coil Pair Selection

Abstract:

A machine implemented method includes alternately energizing multiple transmit coils in a first device, receiving indications of received signal strength at receive coils in a second device, selecting a first pair of coils including a first transmit coil and a first receive coil having the greatest received signal strength, and transferring energy from the first transmit coil to the first receive coil.
