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: Operation input device with few gesture operation erroneous detections is provided. Operation input device includes substrate; plurality of detecting electrodes provided on substrate surface; detecting unit detecting capacitance occurring between each detecting electrode and operating body upon operating body being brought close to substrate; and determining unit determining whether gesture operation by operating body has been performed. Detecting electrodes include first and second electrodes of which capacitance values decrease/increase to match amount of movement of operating body when operating body is moved in longer direction. Upon sensing of operation of moving operating body after being stopped relative to detecting electrodes, or operation of stopping operating body after being moved relative to detecting electrodes, gesture operation by operating body is determined to have been performed. Operating body is determined to be stopped when changes in sum of, and ratio between, capacitance values of first and second electrodes are ≤predetermined values.

Abstract: A door handle, to be attached to a door, includes an outer case, an inner case integrated with the outer case, and a pressure detector configured to detect pressure applied to the inner case. The inner case includes a recess in proximity to an end portion in a longitudinal direction, and the pressure detector detects a displacement of a first inner wall surface on a center portion side of the inner case in the recess, caused by the pressure applied to the inner case.

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.

Abstract: A wakeup process of a living body tactile sensor and a wearing determination unit is performed when an accelerometer detects an acceleration. Accordingly, the living body tactile sensor and the wearing determination unit are in a sleep mode while the accelerometer detects no acceleration. When the wearing determination unit determines a non-wearing state, the wearing determination unit performs a sleep process to switch itself from a wakeup mode to the sleep mode.

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.
