Title (EN) SENSOR FOR SENSING EXISTENCE POSITION OF METALLIC BODY
(FR) CAPTEUR SERVANT A DETECTER L'EMPLACEMENT D'UN CORPS METALLIQUE
Abstract:
(EN) The sensor has a sensing matrix (20) comprising sensing units for sensing objects in the form of a matrix, driving means (40, 50, 63) for receiving the signals representing the states of the sensing units, and sensing means (30) for sensing the existence position of the object on the sensing matrix (20) on the basis of the signals received by the driving means. The sensing means (30) is provided with an offsetting means (30a) for storing the values of the received signal as an offset value for every sensing unit while updating successively, a computing means (30b) for computing the difference between the offset value before updating and the newly received signal value for every respective sensing unit, and a comparing means (30c) for judging the existence of the object by comparing the difference between both of the values with a preset value.
(FR) Le capteur comporte une matrice de détection (20) comprenant des unités détectrices sous forme de matrice servant à détecter des objets, des organes de commande (40, 50, 63) recevant les signaux représentant les états des unité détectrices, et un organe détecteur (30) servant à détecter l'emplacement de l'objet sur la matrice de détection (20) en fonction des signaux reçus par les organes de commande. L'organe détecteur (30) est pourvu d'un organe de décalage (30a) servant à stocker les valeurs du signal reçu sous forme d'une valeur de décalage pour chaque unité détectrice tout en effectuant la mise à jour, d'un organe de calcul (30b) qui calcule la différence entre la valeur de décalage avant la mise à jour et la valeur de signal nouvellement reçue pour chaque unité détectrice respective, et d'un organe comparateur (30c) qui détermine la présence de l'objet en comparant la différence entre les deux valeurs et une valeur fixée d'avance.
