Abstract:
1. A system for inductive power transfer comprising: a send coil transmitting power, a receive coil receiving the power by induction, the receive coil being positioned along an inside surface of a tire, wherein the receive coil having a variable position with respect to the send coil, the position varying as the receive coil rotates with respect to the send coil from a minimum distance between the receive coil and the send coil to a maximum distance, a first communication path formed between the receive coil and the send coil, the first communication path providing a path for transmitting power to the receive coil; and a second communication path formed between the receive coil and the send coil, the second communication path providing a path for a feedback signal to the send coil, wherein the send coil determines a measure of the feedback signal and transmits a full burst of power on the first communication path in response to the feedback signal being of sufficient power, the feedback signal being of sufficient power within an angular alignment window about the minimum distance between the receive coil and the send coil.
