Abstract: A steering wheel grip detection device includes a positive electrode terminal electrically connected to a positive electrode of a power source and a negative electrode terminal electrically connected to a negative electrode of the power source. The steering wheel grip detection device further includes a thermostat, a heater, and an inductance element that are electrically connected with one another in this order in series wiring from the positive electrode terminal to the negative electrode terminal, as well as a capacitor through which a wiring path from the thermostat to the heater is electrically connected with the negative electrode terminal. The steering wheel grip detection device has an electrostatic sensor circuit that is electrically connected with a wiring path from the inductance element to the heater and that detects a grip on a steering wheel by a capacitance value of the heater.

Abstract: To minimize excessively high output or increases in magnetic-flux leakage by controlling power feeding on the power-feeding side if an unforeseen situation occurs. This power-feeding device (100) feeds power to an external power-receiving device (150) in a contactless manner. A power-feeding coil (103) uses electromagnetic power to feed electrical power to a power-receiving coil (154) in the power-receiving device (150). While power is being fed from said power-feeding coil (103), a power-feeding-side control unit (107) determines the amount of displacement of the power-feeding coil (103) and, on the basis of the determined displacement amount, controls the amount of electrical power being fed.
