Abstract: A positioning device for determining a position of a mobile communication device includes a processor that corrects a clock of at least one of a first wireless communication device or a second wireless communication device that is disposed at a first distance from the first wireless communication device, based on a difference between the first distance and a second distance between the first wireless communication device and the second wireless communication device. The second distance is determined based on a first phase of a first signal transmitted at a first frequency from the first wireless communication device and is received by the second wireless communication device, a second phase of a second signal that is transmitted at a second frequency from the first wireless communication device and is received by the second wireless communication device, and the first distance.

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 mobile station M is moved close to a mobile terminal unit 20 as a target object. In ST1, the absolute position of the mobile station M in an absolute coordinate system (Abs) set in a measurement area is calculated. In ST2, the relative position of the mobile terminal unit 20 in a relative coordinate system (Rel) set by the mobile station M is detected. In ST3, the orientation of the mobile station M in the absolute coordinate system (Abs) is detected. In ST4, the relative coordinate system (Rel) is rotated. In ST5, the absolute position of the mobile terminal unit 20 in the absolute coordinate system (Abs) is specified.

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.
