Abstract: A power receiving apparatus includes: a communication circuit that receives a control signal from a power transmitting apparatus through a wired transmission line; a control circuit that determines a propagation time in which the control signal is propagated from the power transmitting apparatus to the power receiving apparatus through the wired transmission line; and a demodulation circuit that receives modulated power from the power transmitting apparatus through a wired transmission line, and demodulates, based on the determined propagation time, the modulated power in synchronization with a phase of the modulated power.

Abstract: A system includes: a first modulator that modulates a first electric power at a first modulation frequency; a second modulator that modulates a second electric power at a second modulation frequency; a transmission line through which a transmission power obtained by combining a plurality of modulated electric powers is transmitted; a first demodulator that demodulates the transmission power at a first demodulation frequency to generate a third electric power; and a second demodulator that demodulates the transmission power at a second demodulation frequency to generate a fourth electric power. The first modulation frequency and the second modulation frequency are different from each other.

Abstract: A foreign object detecting device includes first and second coils, the winding directions of which are the same, and a foreign object detecting circuit. The foreign object detecting circuit outputs a first detecting signal having a first predetermined waveform to a first terminal of the first coil and outputs a second detecting signal having a second predetermined waveform, which has the same polarity as the first predetermined waveform, to a third terminal of the second coil to cause magnetic fields generated from the first and second coils to repel each other. The foreign object detecting circuit measures an amount of change of the impedance value of the first or second coil which is caused by the presence of a foreign object. When the amount of change exceeds a predetermined value, the foreign object detecting circuit determines that there is a foreign object above the first or second coil.

Abstract: A foreign object detecting device includes first, second, and third coils and a foreign object detecting circuit. The foreign object detecting circuit outputs a first detecting signal having a first predetermined waveform to a first terminal of the first coil and outputs a second detecting signal having a second predetermined waveform, which is an inverted form of the first predetermined waveform, to a fifth terminal of the third coil to cause a combined magnetic field extending over the first and third coils. The foreign object detecting circuit measures an amount of change of the impedance value of the first or third coil with respect to a change in the combined magnetic field in the case of the presence of a foreign object. The amount of change exceeds a predetermined value, the foreign object detecting circuit determines that there is a foreign object above the second coil.
