Abstract: A method for operating a wireless power transmission system includes providing a driving signal for driving a transmission antenna of the wireless power transmission system, the driving signal based, at least, on an operating frequency for the wireless power transmission system. The method further includes inverting, by the at least one transistor, a direct current (DC) input power signal to generate an AC wireless signal at the operating frequency, based on provided driving signals. The method includes receiving, at a damping circuit, damping signals configured for switching the damping transistor to one of an active mode and an inactive mode to control signal damping, wherein the damping signals switch to the active mode periodically. The method further includes selectively damping, by the damping circuit, the AC wireless signals, during transmission of the wireless data signals if the damping signals set the damping circuit to the active mode.

Abstract: The present application relates to an apparatus which comprises a wireless power transfer system. This system comprises features which allow it to transfer more power wirelessly at extended distances than other systems operating in the same frequency range. The system possesses heat dissipation features; these features allow it to operate effectively in elevated-temperature environments, and to transfer power at higher levels and/or greater distances than a typical power-transfer system. The system also might include design features to withstand mechanical shocks, stresses, and impacts for use in a rugged environment. The system can also comprise adaptations to reduce electromagnetic interference, and can comprise specially shaped components with magnetic/ferrimagnetic properties that enhance performance. Other potential features include power conditioning by combining, within one circuit or one board, multiple elements that protect against excessive current, over-voltage, and/or reverse voltage.

Abstract: A method of operating a power and data transfer system includes determining, by a wireless transmission system, presence of a wireless receiver system. The method further includes starting wireless power and data transfer via the wireless transmission system, if presence of the wireless receiver system is detected. The method further includes determining if power at a load associated with the wireless receiver system exceeds a threshold for out of band communications. The method further includes, if the power at the load exceeds the threshold for out of band communications, handing over wireless data transfer to an out of band communications system that is in operative communication with the wireless transmission system.
