Abstract: Object detection in wireless power systems and related system, methods, and devices are disclosed. A controller for a wireless power transmitter includes a measurement voltage potential input terminal and a processing core. The processing core is to determine an average of peak to peak amplitude differences present in sampled measurement voltage potentials for each of the plurality of transmit coils, determine a lowest average of the peak to peak amplitude differences, and select a transmit coil corresponding to the lowest average of the peak to peak amplitude differences to transmit wireless power to a receive coil of a wireless power receiver. A wireless power system includes a tank circuit selectively including any one of a plurality of transmit coils.

Abstract: A dynamic capacitive power transfer system for an elevator that can realize the real-time powering of the elevator when it is in the moving status. It includes a metal track along the building side as the power transmitter and a piece of metal at the elevator side as the power receiver. There is a gap between the transmitter and receiver, and up to kW power can be transferred wirelessly and efficiently to serve the air conditioner, lightning, and other electronic devices in the moving car. The steel wheels and ropes may be used to connect the moving car to the earth ground, which contributes to form the current returning loop. It eliminates the electric cables and the corresponding flexible cable carrier system for the linear movement.
