Title
(EN) PROXIMITY SENSOR
(FR) CAPTEUR DE PROXIMITE DE
Abstract
(EN) An immersion sensor 12 for use with a cushion 10 or mattress 208 for determining the relative immersion of a person within the cushion or mattress comprising a sensor 18, a ground 28 and a circuit 30 for measuring capacitance. The sensor comprises a sheet of conductive material, and the ground comprises a second sheet of conductive material. The circuit is adapted to send short bursts of electrical current to the sensor and a capacitor 46. The circuit is further adapted to measure the length of time the burst of current takes to charge the capacitor. Based upon the measured time, the circuit calculates the proximity of the object based upon the time taken to charge the capacitor. A method that may be implemented with the immersion sensor is also disclosed.
(FR) L'invention porte sur un capteur d'immersion (12) destiné être utilisé avec un coussin (10) ou matelas (208) afin de déterminer l'immersion relative d'une personne dans le coussin ou le matelas comprenant un capteur (18), une terre (28) et un circuit (30) pour mesurer la capacitance. Le capteur comprend une feuille de matériau conducteur, et la terre comprend une seconde feuille de matériau conducteur. Le circuit est adapté pour envoyer de brèves rafales de courant électrique au capteur et à un condensateur (46). Le circuit est également adapté pour mesurer la durée que la rafale de courant met à charger le condensateur. En fonction de la durée mesurée, le circuit calcule la proximité de l'objet en fonction du temps mis pour charger le condensateur. L'invention porte également sur un procédé qui peut être mis en oeuvre avec le capteur d'immersion.
