Abstract: A power receiver is provided herein. The power receiver provides in-band communication with a power transmitter. The power receiver recognizes a change in frequency that identifies a training sequence and determines an impulse response with respect to the training sequence. The power receiver also cancels an effect of the impulse response during the in-band communication.

Abstract: A transmitter may inductively transfer power to a device via a relay. The transmitter may comprise circuitry configured to measure a current or voltage and reconfigure the transmitter with an operating frequency or duty cycle based on a measured change in the current or voltage within a time period. The measured change in the current or voltage within the time period may be caused by a removal of the device or an addition of a new device. The time period may be 200 usec or less.

Abstract: An inductive power outlet operable to transfer power to an inductive power receiver includes a driver wired to a primary inductive coil and operable to provide a driving voltage across the primary inductive coil. The primary inductive coil is configured to form an inductive couple having a characteristic resonant frequency with at least one secondary inductive coil wired to an electric load, the secondary inductive coil being associated with the inductive power receiver. The driving voltage oscillates at a transmission frequency substantially different from the characteristic resonant frequency of the inductive couple.
