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 tilt adjusting image including a captured image that is obtained by capturing a wearer wearing a spectacle-type electronic device, and a horizontal line image indicating a horizontal direction identified by a tilt identification part, is displayed. The wearer adjusts a position of the spectacle-type electronic device by a wearer's hand or the like while viewing the tilt adjusting image so that the spectacle-type electronic device becomes horizontal. When the wearer judges that the spectacle-type electronic device has become horizontal, the wearer operates an operation part and inputs a calibration instruction. When the calibration instruction is input, the calibration instruction is transmitted to the spectacle-type electronic device.

Abstract: A position detection system according to an embodiment of the present invention includes a plurality of fixed stations 20; and a sensor unit 10 including an inertial sensor that detects movement history of a mobile body 51 and a distance sensor that detects separation distances between the mobile body 51 and the fixed stations 20. A position of the mobile body 51 is determined by detecting a first arrival position P1 obtained based on the movement history, a second arrival position P2 obtained based on the separation distances, and a relative distance L1 between the first arrival position P1 and the second arrival position P2, and by comparing a range value R1 obtained based on the movement history with the relative distance L1. The range value R1 is changed based on the movement history.

Abstract: Accelerations (Ax, Ay, Az) in directions along (X′, Y′, Z′) detected by an acceleration sensor 10 are converted, based on a correction angle γ, which is an angle between a first detection axis X′ and a first posture axis X, into accelerations (Bx By, Bz) in directions along three posture axes (X, Y, Z). A pitch angle α and a roll angle β, which indicate a posture of a portion to which the wearable device is attached, are calculated based on the accelerations (Bx By, Bz) obtained by the conversion based on the correction angle γ.

Abstract: In order to provide a receiver capable of accurately determining a phase difference of I/Q signals, a receiver includes a section detector configured to detect a section between a rising and a falling of a phase based on the rising and the falling of the phase represented by I/Q signals generated based on an advertisement packet transmitted from a transmitter, and a section setting unit configured to identify, within the section between the rising and the falling of the phase, a period in which a first variation amount of the phase is equal to or less than a first predetermined amount, and use the identified period as a section for detecting the phase of the I/Q signals. The section detector detects the rising when a first phase is smaller than a last phase among a plurality of phases acquired by sampling the phases.

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: In a position detection system that has a plurality of transmitters/receivers placed at least three positions: processing is executed to measure distances among the plurality of transmitters/receivers, each distance being measured a plurality of times, and obtain a minimum value for each distance; processing is executed to obtain an angle between each two adjacent straight lines, each of which is one of straight lines that mutually connect the plurality of transmitters/receivers, by using minimum values, each of which is the minimum value for each distance; and if the absolute value of the difference between 180 degrees and the sum of angles, each of which is the angle between each two adjacent straight lines, inside a triangle formed by straight lines that interconnect three of the plurality of transmitters/receivers is smaller than a predetermined value, processing is executed to take the minimum values as the true values of the distances.
