Abstract: PROBLEM TO BE SOLVED: To simply install, on a fixed object, a motion sensor capable of detecting movement of the fixed object, when it is moved.
SOLUTION: The motion sensor includes an accelerator for respectively detecting acceleration in three-axial directions and a control part for detecting the movement from the acceleration in the three-axial directions detected by the accelerator. The control part acquires an acceleration detection signal from the accelerator, obtains an acceleration measurement value of each axis, determines whether the motion sensor stands still or is moving, based on the acceleration measurement value, and calculates a posture angle of the motion sensor using the acceleration measurement value of each axis when the sensor is determined to stand still. Meanwhile, when the motion sensor is determined to be moving, horizontal acceleration is calculated by means of the posture angle of the motion sensor, which is calculated when the sensor is determined as being stationary so as to determine whether the sensor is moving, based on the horizontal acceleration.

Abstract: PROBLEM TO BE SOLVED: To provide a temperature compensation method of a radio range finder capable of performing the temperature compensation with a simple constitution and capable of measurement free from influence caused by temperature variation.
SOLUTION: The transmission leakage signal, which does not progress from the transmission circuit 1 to the antenna 4 but leaks to the receiving circuit 3, is influenced by the temperature variation depending on the coupling between a transmission circuit 1 and a receiving circuit 3, and the position and intensity of the transmission leakage signal are varied. The receiving signal is also influenced by temperature variation. Therefore, the reference value of the position or intensity of the transmission leakage signal is previously recorded in a memory 19 and compared to the position or intensity of the measured transmission leakage signal, according to the comparison result, the calibration is performed.
