Title
(EN) THERMAL MOVEMENT SENSOR
(FR) CAPTEUR DE MOUVEMENT THERMIQUE
Abstract
(EN)
A transducer for detecting movement of an article mounted for movement in a plane, the transducer comprising: a heater facing the plane of movement of the article and having a temperature dependent resistance; and, an edge defined in the article between regions of different thermal conductivity; wherein, as the article describes the movement, the edge moves relative to the heater producing a corresponding variation in heat loss from the heater and a corresponding variation in resistance of the heater.
(FR)
L'invention concerne un transducteur servant à détecter les mouvements d'un article monté de façon mobile dans un plan. Ce transducteur comprend : un générateur d'énergie thermique orienté face au plan de mouvement de l'article, ayant une résistance dépendant de la température ; et, un bord défini dans l'article, entre des zones de conductivité thermique différente. Lorsque l'article décrit un mouvement, le bord se déplace par rapport au générateur d'énergie thermique, produisant une variation de perte de chaleur correspondante à partir du générateur d'énergie thermique et une variation correspondante dans la résistance du générateur d'énergie thermique.
