Abstract:
1. A method for controlling an inductive power supply to supply power to at least one remote device, comprising the steps of: providing the at least one remote device having device circuitry and a secondary configured for receiving operating wireless power, wherein the operating wireless power is used to operate the device circuitry, wherein at least one of a plurality of identification frequencies being associated with each of the at least one remote device, wherein each of the at least one remote device has a resonant frequency at or near at least one frequency from among the plurality of identification frequencies; selecting an identification frequency from among the plurality of identification frequencies; applying an inductive field to the at least one remote device at the identification frequency; determining whether the at least one remote device has the resonant frequency substantially at the applied identification frequency to identify the at least one remote device; and operating the inductive power supply to supply the operating wireless power to the identified at least one remote device according to an operating parameter based on an outcome of said determining step, wherein the operating parameter corresponds to the identified at least one remote device.
