    摘要： A power feed system according to the present disclosure includes a power feed device and a power receiving device. The power receiving device includes a power receiving section that receives power wirelessly from the power feed device with use of a power receiving coil, and a first communication section that transmits, to the power feed device, coil information indicating whether or not a coil is provided near the power receiving coil. The power feed device includes a power feed section that supplies power wirelessly to the power receiving device, a second communication section that receives the coil information, and a controller that performs, on the basis of the coil information, a first determination as to whether or not to supply power to the power receiving device, and controls an operation of the power feed section on the basis of a result of the first determination.

    摘要： In an example, an integrated circuit includes a communication and control unit. The communication and control unit controls an inverter that applies an alternating current output signal to a transmission coil for reception by a receiver. The communication and control unit causes the inverter to provide a first and second transmit powers to the transmission coil, and the communication unit receives a first and second power received signals from the receiver in response to the first and second transmit powers. The communication and control unit determines a first gain and offset using the first transmit power, the first power. When a third transmit power greater than the second transmit power is transmitted by the transmission coil, the communication and control unit determines a second gain and a second offset using the first transmit power, the first power received signal, the third transmit power and a third power received signal.
