Abstract
A power delivery system wirelessly deliver electric power and a communication signal to a target device. The power delivery system includes a power transmitting unit having a power source operable to source alternating current power and a sending resonant coupling component operable to couple the alternating current power to a coil for wireless power transmission by a non-radiated magnetic field at a target resonant frequency. The power transmitting unit is capable of dynamically tuning the wireless power transmission to the target resonant frequency wherein the target resonant frequency is specified dynamically. A communication module couples to the power transmitting unit and is operable to couple the communication signal to the non-radiated magnetic field. Operations may include target device authentication, target resonant frequency information communication, billing, and device management.
