Abstract: A door handle includes a door handle case and an electrostatic sensor provided in the door handle case. The electrostatic sensor includes a detection electrode that is formed of a flat conductor plate, or that is formed on a surface of a flat substrate or within a flat substrate. The detection electrode includes a middle portion in a longitudinal direction of the detection electrode and includes peripheral portions proximal to both end portions of the detection electrode in the longitudinal direction. For a width of the detection electrode in a direction perpendicular to the longitudinal direction, each peripheral portion is wider than the middle portion, and the width of the detection electrode gradually increases toward each end portion in the longitudinal direction.

Abstract: A door handle includes door handle case, a first detection electrode and a second detection electrode disposed in the door handle case, and a controller connected to the first detection electrode and the second detection electrode. The controller separately measures a first capacitance between the first detection electrode and an operation body and a second capacitance between the second detection electrode and the operation body, and the controller determines whether a locking operation is performed by the operation body based on one or both of the first capacitance and the second capacitance.

Abstract: An operation signal generating unit 11 and a reset unit 12 are included in a first circuit unit 10 that operates based on a first power supply voltage V1 and an output operation of a second power supply voltage B2 is stopped by outputting a reset signal Sr from the reset unit 12 to a regulator 20 in accordance with an operation signal Si of the operation signal generating unit 11. Hence, unlike a conventional technique, a large transistor for cutting off a power supply line is unnecessary, and therefore a device size can be reduced.

Abstract: An electrostatic sensor includes a detection electrode, a shield electrode provided in a periphery of the detection electrode, a first power supply coupled to the detection electrode and configured to generate an AC voltage having a first amplitude, a second power supply coupled to the shield electrode and configured to generate an AC voltage having a second amplitude, a measuring device configured to measure a quantity of charge flowing from the first power supply to the detection electrode, and a control device coupled to the measuring device. The AC voltages generated by the first and second power supplies have the same frequency and the same phase. The second amplitude is larger than the first amplitude. A detection target on a side of a detection surface is detected based on a change in an electrostatic capacitance between the detection electrode and the detection target.

Abstract: An operation device includes a housing, an operation member, and a detector. The housing includes an electrically conductive portion on a surface thereof. The operation member is supported by the housing such that the operation member is movable in response to an operation by an operation body, and is configured to be capacitively coupled to the operation body and to the electrically conductive portion. The detector is configured to detect whether the operation body is in proximity to the operation member based on a change in capacitance at the electrically conductive portion.
