Title
(EN) SENSOR DEVICE AND METHOD OF DETECTING A SENSOR EVENT
(FR) DISPOSITIF DE CAPTEUR ET PROCEDE DE DETECTION D'UN EVENEMENT DE CAPTEUR
Abstract
(EN)
A sensor device comprises an object having at least one magnetically encoded region thereon, at least two magnetic field detectors adapted to detect, as detecting signals, a magnetic field generated by the at least one magnetically encoded region in case of a sensor event, and a processing unit coupled with the at least two magnetic field detectors to be provided with the detecting signals adapted to simultaneously process the detection signals to compensate artificial differences between the detection signals.
(FR)
L'invention concerne un dispositif de capteur comprenant un objet possédant au moins une région codée de manière magnétique, au moins deux détecteurs de champs magnétiques conçus pour détecter, sous forme de signaux de détection, un champ magnétique généré par la région codée de manière magnétique dans le cas d'un événement de capteur et une unité de traitement couplée aux deux détecteurs de champs magnétiques, les signaux de détection de ceux-ci étant conçus pour traiter les signaux de détection et pour compenser simultanément les différences artificielles entre les signaux de détection.
