Patent number: 11990771Abstract: A method for wireless power transmission includes obtaining, via a Q-value circuit, first and second voltages at respective first and second nodes of a resonance circuit. The first and second voltages are effective to determine if foreign matter is present in a space affecting wireless power transmission. The method includes controlling a switching section between the Q-value circuit and the resonance circuit such that at least a part of the electric power transmission process occurs at a different time than when the first and second voltages are obtained.Type: GrantFiled: April 14, 2017Date of Patent: May 21, 2024Inventors: Hiroaki Nakano, Takaaki Hashiguchi, Shinichi Fukuda, Kenichi Fujimaki
