Title (EN) NORMALIZING CAPACITIVE SENSOR ARRAY SIGNALS
(FR) NORMALISATION DES SIGNAUX DE RÉSEAU DE CAPTEURS CAPACITIFS
Abstract:
(EN) An embodiment of the present invention is directed to a method for processing a position signal. The method includes receiving a first position signal from a capacitive sensor and determining a proximity of the capacitive sensor to a connection of an array of capacitive sensors. The sensitivity of the capacitive sensor is then adjusted and a second position signal is received from the capacitive sensor. The second position signal may then be reported. The present invention facilitates more accurate readings from an array of capacitive sensors.
(FR) La présente invention concerne, dans un mode de réalisation, un procédé de traitement d'un signal de position. Le procédé comprend la réception d'un premier signal de position par un capteur capacitif et la détermination de la proximité du capteur capacitif par rapport à une connexion d'un réseau de capteurs capacitifs. La sensibilité du capteur capacitif est ensuite ajustée et un second signal de position est reçu par le capteur capacitif. Le second signal de position peut alors être signalé. La présente invention facilite des lectures plus précises par un réseau de capteurs capacitifs.
