Abstract
Embodiments disclosed herein relate to wireless charging systems and method of transmitting power waves. An exemplary method includes receiving, from one or more first sensors, first data of a transmission field. After receiving the first data, the method includes determining whether a path between a wireless power receiver located in the transmission field and a first wireless power transmitter is unobstructed based, at least in part, on the first data. In accordance with a determination that the path between the wireless power receiver and the first wireless power transmitter is unobstructed, the method includes transmitting, by the first wireless power transmitter, electromagnetic wireless power transmission waves to the wireless power receiver. The wireless power receiver uses energy from at least some of the electromagnetic wireless power transmission waves to power or charge an electronic device coupled to the wireless power receiver.
