Abstract: A positioning system includes: a transmitting and receiving part having multiple antennas and positioned overhead in a positioning target area with a side entrance; a distance calculation part configured to calculate a distance between a communication device that can move in the positioning target area, and the transmitting and receiving part, based on results gained from signals of multiple frequencies transmitted bidirectionally between the communication device and the transmitting and receiving part; an angle calculation part configured to calculate an angle that indicates a position of the communication device with respect to the transmitting and receiving part, based on a phase difference between the signals received by the antennas of the transmitting and receiving part; and a determining part configured to determine whether or not the communication device is approaching the side entrance based on the distance and angle calculated by the distance calculation part and the angle calculation part.

Abstract: A positioning system includes an elevation angle calculator that determines, as a second elevation angle, an inverse cosine of a first value, upon occurrence of a condition in which an absolute value of a first elevation angle is greater than or equal to a second predetermined angle, the second predetermined angle being greater than a first predetermined angle, the first value being obtained by dividing a second value that is obtained by correcting, with a correction value, an altitude measured by an altitude measurement unit, by a distance measured by a distance measurement unit. The elevation angle calculator selects any one of the first elevation angle and the second elevation angle, based on a value of the first elevation angle.

Abstract: A door handle including a capacitance sensor configured to detect an operation body is provided. The capacitance sensor includes a substrate formed of an insulator and having a surface, at least one first sensor electrode disposed on the surface of the substrate, a plurality of second sensor electrodes disposed on the surface of the substrate, and a controller. The number of the plurality of second sensor electrodes is greater than the number of the at least one first sensor electrode. The controller applies a voltage to the plurality of second sensor electrodes and detects a coordinate position of the operation body, in a case where a capacitance between the operation body and the at least one first sensor electrode is greater than or equal to a predetermined value.

Abstract: An operation input device includes a resistance element to generate a capacitance between an operating medium and the resistance element in response to an approach of the operating medium to the resistance element, and a power source to supply electric charge to one end and the other end of the resistance element. A first electric unit measures a first electric charge transfer amount supplied to the one end of the resistance element in response to generation of the capacitance. A second unit measures a second electric charge transfer amount supplied to the other end of the resistance element in response to generation of the capacitance. A controller is connected to the first and second units, and detects a position of the operating medium in a direction perpendicular to a surface of the resistance element based on a sum of the first and second electric charge transfer amounts.
