Abstract
A method and apparatus is used for adaptive inductive charging of a device. Charging includes detecting the presence of a device capable of receiving an inductive charge, determining a set of parameters for inductively charging the device, and transmitting an inductive charge corresponding to the set of parameters for charging the device. Another aspect of charging includes combining at least two inductive fields transmitted at different angles to each other, delivering the combined inductive field at an orientation to the device, measuring the load on the device to determine the effectiveness of the orientation of the inductive field when charging the device, and charging the device at the orientation of the inductive field when the measured load on the device exceeds a threshold load level.
