Abstract: A motion analysis device includes two posture angle sensors attached to a measurement object at locations distant from each other, a data acquisition section, a posture angle correction section, and a deformation amount calculation section. The data acquisition section acquires data of a first posture angle and a second posture angle respectively detected by the posture angle sensors. The posture angle correction section corrects a difference between the first posture angle and the second posture angle after starting a motion of the measurement object in accordance with a difference between the first posture angle and the second posture angle before starting the motion of the measurement object. The deformation amount calculation section calculates a deformation amount of the measurement object based on a difference between the first posture angle and the second posture angle corrected by the posture angle correction section.

Abstract: A quartz oscillator for quadrature modulation has a quartz oscillating circuit including a transistor, a quartz oscillator, a capacitor, and a resistor, a double-mode quartz filter, a reactance element, and an amplifier. The quartz oscillator is constituted so that an output of the quartz oscillating circuit is a first output, and its output is connected to one terminal of the double-mode quartz filter where a common electrode is grounded. The reactance element is connected in parallel between the other terminal and the ground, and a second output is obtained from a connected point via the amplifier.

Abstract: A selective calling receiver with automatic memory storage and turn-on indication is disclosed. When the receiver is placed in the called state by an incoming signal, audible and/or visual indicator signals actuated by the incoming signal are automatically stopped after a predetermined period of time has elapsed and record of the called state is simultaneously kept in a memory integral to the receiver. Indication of the called state is regenerable at a later time by a switching operation. Indication of the called state is stoppable without recording such indication in memory when a manual reset operation is performed before indication of the called state is automatically stopped.
