Title
(EN) A sensor system and method which makes use of multiple ppg sensors
(ZH) 利用多个PPG传感器的传感器系统和方法
Abstract
(EN)
A sensor system comprises first and second PPG sensors. A monitoring system monitors detection by at least one of the first and second detectors an optical calibration signals, for performing time calibration between the first and second PPG sensors. This system makes use of two PPG sensors. To enable these sensors to be independent units, rather than being fully integrated into a combined system,a calibration system is provided. Based on detected optical signals, the behavior over time of each PPG sensor can be monitored and thus calibration can take place.

一种传感器系统,包括第一PPG传感器和第二PPG传感器。监测系统监测由第一探测器和第二探测器中的至少一个对光学校准信号的探测,用于执行所述第一PPG传感器与所述第二PPG传感器之间的时间校准。所述系统利用两个PPG传感器。为了使得这些传感器能够是独立的单元,而非被完全集成到组合系统中,提供了一种校准系统。基于探测到的光学信号,能够监测每个PPG传感器的随时间的行为,并且因此能够进行校准。
