First Claim
1. For use in wirelessly charging portable devices and in both powering and authenticating remote operator-carried transponders for activating an automotive circuit, an apparatus comprising:
- a portable device including circuitry configured to be wirelessly charged;
a first circuit-based module including signal transmission circuitry and configured an arranged tooperate in a first mode to generate and transmit a first signal to wirelessly charge a portable device, wherein the first circuit-based module is configured to communicate and exchange data with the portable device while in the first mode and while wirelessly charging the portable device by energy sourced from the first signal, andin response to detecting the presence of a remote transponder, operate in a second mode to generate and transmit a second signal to power and communicate authentication data with the remote transponder; and
a second circuit-based module including logic circuitry and configured and arranged to authenticate the transponder by accessing and processing stored authentication data with authentication data carried in signals received from the remote transponder via the first module, and generate an output for activating the automotive circuit based upon the authentication.

Abstract
Wireless charging and data communication are effected. In accordance with various example embodiments, a transceiver-type circuit wirelessly charges portable devices, such as hand-held telephones via wireless signals, and also wirelessly communicates data with remote transponders. The data communication is carried out to facilitate authentication of the remote transponders and may, for example, be limited relative to a power-carrying capability of the transponders. Such aspects may be implemented, for example, in a transceiver for both transponder-based operation and (high-power) wireless charging applications in vehicle-based circuits.
