Title (EN) OPTICAL MOTION REJECTION
(FR) REJET DE MOUVEMENT OPTIQUE
Abstract:
(EN) An electronic fitness device comprises first and second optical transmitters, an optical receiver, and a processing element. The first optical transmitter is configured to transmit a first optical signal having a first wavelength. The second optical transmitter is configured to transmit a first optical signal having a second wavelength. The optical receiver is configured to receive the first and second optical signals and to generate first and second photoplethysmogram (PPG) signals respectively resulting from the received optical signals. The processing element is configured to control the first and second optical transmitters to transmit the first and second optical signals, receive the first and second PPG signals, and utilize the second PPG signal to reduce a noise component from the first PPG signal.
(FR) Un dispositif d'exercice physique électronique comprend des premier et second transmetteurs optiques, un récepteur optique et un élément de traitement. Le premier transmetteur optique est configuré pour transmettre un premier signal optique ayant une première longueur d'onde. Le second transmetteur optique est configuré pour transmettre un premier signal optique ayant une seconde longueur d'onde. Le récepteur optique est configuré pour recevoir les premier et second signaux optiques et pour générer des premier et second signaux de photopléthysmogramme (PPG) résultant respectivement des signaux optiques reçus. L'élément de traitement est configuré pour commander les premier et second émetteurs optiques pour transmettre les premier et second signaux optiques, recevoir les premier et second signaux PPG, et utiliser le second signal PPG pour réduire une composante de bruit à partir du premier signal PPG.
