Patent number: 11979201Abstract: An inductive power outlet is disclosed. The inductive power outlet has a primary inductor, for wirelessly powering an inductive power receiver. The inductive power outlet has a secondary inductor. The primary inductor and the secondary inductor form a resonant frequency. The inductive power outlet comprises a driver generating an oscillating voltage to the primary coil at a frequency higher than the resonant frequency. The inductive power outlet comprises a signal detector. The signal detector comprises a peak detector configured to detect voltage peaks across the primary inductor or current peaks of a current supplied to the primary inductor. The signal detector comprises a processor configured to determine a frequency of either the voltage peaks or the current peaks.Type: GrantFiled: July 11, 2022Date of Patent: May 7, 2024Assignee: POWERMAT TECHNOLOGIES LTD.Inventors: Yossi Azancot, Arik Rofe, Oola Greenwald, Amir Ben-Shalom, Moti Asheri, Alfred Leibovitz
