Title
(DE) SENSORSYSTEM UND VERFAHREN ZUR VERWENDUNG MEHRERER PPG-SENSOREN
(EN) A SENSOR SYSTEM AND METHOD WHICH MAKES USE OF MULTIPLE PPG SENSORS
(FR) SYSTÈME DE CAPTEUR ET PROCÉDÉ QUI UTILISE DE MULTIPLES CAPTEURS DE PPG
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.

(FR)
Système de capteur comprenant des premier et second capteurs de PPG. Un système de surveillance surveille la détection d'un signal d'étalonnage optique par au moins l'un des premier ou second détecteurs, pour effectuer l'étalonnage temporel entre le premier et le second des capteurs de PPG. Ce système utilise deux capteurs de PPG. Un système d'étalonnage est fourni pour permettre à ces capteurs d'être des unités indépendantes, plutôt que d'être entièrement intégrés dans un système combiné. Sur la base des signaux optiques détectés, le comportement dans le temps de chaque capteur de PPG peut être surveillé, ce qui permet de réaliser l'étalonnage.
