Problems solved by technology

This method has the disadvantage that the spacing between the transmit and receive antennas must be very close (e.g. within a few thousandths of a meter)
But this method does not have the ability to simultaneously charge multiple devices in the same area, which is usually very small and requires the user to precisely locate the device to a specific area

Abstract

Exemplary embodiments are directed to communicating information relating to wireless charging. A power transmitting system includes a host device with a transmit antenna. A communication interface conveys receiver information, which includes unique identifier information, from a receiver device to the host device. A controller on the host device monitors and processes the receiver information to generate notification information, which is presented to a user on a user-perceivable notifier. The transmit antenna generates an electromagnetic field at a resonant frequency to create a coupling-mode region within a near-field of the transmit antenna. The system can detect a presence of a receiver device with a receive antenna that is in the coupling-mode region and process a request for power from the receiver device. The system can also notify a user when a host device is leaving a designated region and whether the host device includes expected receiver devices.

Description

[0001] Claim of priority under 35 U.S.C. §119 [0002] This application claims priority under 35 U.S.C. § 119(e): [0003] U.S. Provisional Patent Application No. 61 / 164,410, entitled TRACKING OBJECTS LOCATED WITHIN WIRELESS CHARGING SYSTEMS, filed March 28, 2009, and assigned to the present recipient is hereby expressly incorporated herein by reference. technical field [0004] The present disclosure relates generally to wireless charging, and more particularly to devices, systems, and methods related to tracking receiver devices that may be located in wireless power systems. Background technique [0005] Typically, each battery powered device (eg, wireless electronic device) requires its own charger and power source, typically an alternating current (AC) power outlet. Such wired configurations become inconvenient to use when many devices need to be charged. [0006] Methods are being developed that use over-the-air or wireless power transmission between a transmitter a...
