Title:
SIGNAL DETECTION DEVICE AND SIGNAL DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/033430
Kind Code:
A1
Abstract:
The present invention includes a measurement unit (10), a calculation unit (20), and a cycle detection unit (30), and accurately detects information such as a heartbeat cycle by resonating only strong pulsatile signals such as heart beats. The measurement unit (10) measures a signal. The calculation unit (20) amplifies a pulsatile component of the signal measured by the measurement unit (10) and performs nonlinear vibration calculation which decreases components other than the pulsatile component of the signal measured by the measurement unit. The cycle detection unit (30) detects a cycle signal from output of the calculation unit.
