Title:
COMPOUND SENSOR
Document Type and Number:
WIPO Patent Application WO/2017/164052
Kind Code:
A1
Abstract:
This compound sensor is provided with: an angular velocity detecting element which outputs a sensing signal in accordance with an applied angular velocity; a sensing circuit which outputs an angular velocity signal representing the angular velocity, on the basis of the sensing signal; an acceleration detecting element which outputs a signal corresponding to an applied acceleration; an acceleration detecting circuit which outputs an acceleration signal representing the acceleration, on the basis of the signal output from the acceleration detecting element; a band-pass filter into which the acceleration signal is input; an amplitude assessing circuit which assesses whether the angular velocity signal is invalid, in accordance with the amplitude of a signal output from the band-pass filter; and a timing control circuit which outputs a sensor output signal including the angular velocity signal and the acceleration signal.
