Patent ID: 7825625

Claim:
A wireless charging device for charging electronic devices placed in a docking area of the wireless charging device, the wireless charging device comprising: an inductive coupler configured to charge at least one electronic device through an inductive coupling, wherein the electronic device is present in the docking area, and maintain a communication link with the at least one electronic device for exchanging of a set of information, the set of information used during the charging of the at least one electronic device; a reflected power detector operably coupled to the inductive coupler, said reflected power detector configured to identify the set of information received from the inductive coupler, wherein said reflected power detector further comprises an embedded modulator configured to modulate a charging field of said wireless charging device to maintain a closed loop communication with the at least one electronic device and to allow constant exchange of the set of information in a feedback manner; a power source capable of providing power to the inductive coupler; and a power control system operably coupled to the reflected power detector and the power source for constantly controlling the charging of the at least one electronic device by the power source through the inductive coupler based on the set of information identified by the reflected power detector in the closed loop communication during the charging operation.
