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 sensory control method includes a step of receiving, a step of converting, and a step of outputting. In the step of receiving, a sensitivity parameter is received. In the step of converting, the received sensitivity parameter is converted into, among a plurality of physical parameters included in physical properties relating to a sensory presentation, a physical parameter correlated with the sensitivity parameter. In the step of outputting, a sensory presentation signal based on the physical parameter obtained as a result of the conversion is output.

Abstract: An operating apparatus includes an operating unit capable of a movement operation, a load application unit configured to apply a load to the movement operation of the operating unit based on predetermined load characteristics, and an adjustment unit configured to adjust the load characteristics based on a moving speed of the operating unit after the operating unit reaches a predetermined position. The load characteristics include a first period in which the load is decreased after the operating unit reaches a predetermined position and a second period in which the load is increased after the first period. The adjustment unit adjusts the load characteristics of the first period based on the moving speed in the first period, wherein, when the moving speed in the first period is less than a predetermined speed, the adjustment unit adjusts the load characteristics of the first period so as to extend the first period.

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: 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.
