Abstract

L'invention concerne un système de mesure de bio-informations qui comprend : une première partie électroluminescente qui applique de la lumière à une première région qui est sur une main ou un pied d'un sujet ; une première partie de réception de lumière qui reçoit de la lumière qui est réfléchie depuis la première région ou qui passe à travers celle-ci ; une seconde partie électroluminescente qui applique de la lumière à une seconde région qui est sur la tête ou le cou du sujet ; une seconde partie de réception de lumière qui reçoit de la lumière qui est réfléchie depuis la seconde région ou qui passe à travers celle-ci ; une première partie de génération de valeur de mesure qui, sur la base de changements de la quantité de lumière reçue au niveau de la première partie de réception de lumière, génère des premières valeurs de mesure qui sont associées à une onde de pulsation et à l'hémoglobine ; et une seconde partie de génération de valeur de mesure qui, sur la base de changements de la quantité de lumière reçue au niveau de la seconde partie de réception de lumière, génère des secondes valeurs de mesure qui sont associées à une onde de pulsation et à l'hémoglobine.
