Title (EN) PHYSIOLOGICAL CONTACT SENSOR WITH NO EMBEDDED LIGHT SOURCE
(FR) CAPTEUR DE CONTACT PHYSIOLOGIQUE SANS SOURCE DE LUMIÈRE INTÉGRÉE
Abstract:
(EN) A portable device for determining physiological parameters of a user using ambient light is provided. A first and a second photo detector are used to determine a first signal comprising a first ambient light component and a second signal comprising a second ambient light component along with a modified ambient light component, respectively. The first signal is used to correct the second signal in order to extract the modified ambient light component and determine the physiological parameter on the basis of said modified ambient light component.
(FR) L'invention concerne un dispositif portable destiné à déterminer des paramètres physiologiques d'un utilisateur à l'aide de lumière ambiante. Un premier et un second photodétecteur sont utilisés pour déterminer un premier signal comprenant une première composante de lumière ambiante et un second signal comprenant une seconde composante de lumière ambiante conjointement avec une composante de lumière ambiante modifiée, respectivement. Le premier signal est utilisé pour corriger le second signal afin d'extraire le composant de lumière ambiante modifié et de déterminer le paramètre physiologique sur la base dudit composant de lumière ambiante modifié.
