Abstract: A method may comprise determining a coupling factor between a coil of a transmitter and a coil of a relay based on a joint resonance frequency between the coil of the transmitter and the coil of the relay. The determining may occur when the coil of the relay and the coil of the transmitter are separated by a medium. The transmitter may inductively transmit power for wirelessly charging a device located near the relay. An operating frequency range, having a minimal operating frequency and a maximal operating frequency, may be determined based on the coupling factor. Power may be inductively transmitted in accordance with the minimal operating frequency and the maximal operating frequency.

Abstract: According to a first aspect of the present disclosed subject matter, a dynamic calibration method in a system comprising a relay, having a coil, adapted to inductively transfer power for charging a device and a transmitter, having a coil and a controller configured to inductively transmit to the relay the power for charging the device, wherein the transmitter and the relay are separated by a medium, the method comprising: determining operating parameters selected from a group consisting of minimal and maximal operating frequency; direction of power increase relative to operating frequency; minimal and maximal duty cycle; minimal and maximal operating amplitude; and any combination thereof; wherein the operating parameters and a ping frequency are determined based on dynamic measurements of the transmitter operation and calculations executed by the controller during the calibration.
