    Abstract: A heater device includes: a base member; a heater wire; and a sensor which measures capacitance of the heater wire, wherein the heater wire forms a first wiring pattern and a second wiring pattern connected in series, the first wiring pattern and the second wiring pattern each include N wire blocks, the N wire blocks included in the first wiring pattern and the second wiring pattern are disposed in a manner that arrangement of the N wire blocks included in the first wiring pattern and arrangement of the N wire blocks included in the second wiring pattern are reversed in the circumferential direction of the rim and facing each other in a direction perpendicular to the circumferential direction, and a sum of sensitivity of the sensor to capacitance of a pair of wire blocks facing each other is substantially equal to that of another pair.

    Abstract: A grip sensor includes: a plurality of capacitive detectors which are disposed in a grip of a steering wheel of a vehicle, and output values which vary according to whether a human body is in contact; and a controller which determines, at a preset timing, a reference value to be subtracted from the values output from the plurality of capacitive detectors, to determine whether the human body is in contact, wherein the controller identifies, from among values output from the plurality of capacitive detectors at the preset timing, one or more values each having an absolute value smaller than a first threshold, and determines, as the reference value, one of the one or more values identified or an average of the one or more values identified.

    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.
