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: 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 remote communication system includes a portable device; and a fixed system. The fixed system includes main communication modules; and a position estimating unit configured to estimate a position of the portable device, based on an incident angle of a signal from the portable device, upon detecting the signal by antennas provided in the main communication modules. When there are two main communication modules for which the incident angle is known, the position of the portable device is estimated based on the incident angle. When there is one main communication module for which the incident angle is known, the position of the portable device is estimated based on the incident angle and a received radio wave intensity of the signal. When there is no main communication module for which the incident angle is known, the position of the portable device is estimated based on the received radio wave intensity.
