Title
(EN) IMPROVEMENTS TO SWITCHING SYSTEMS
(FR) AMELIORATIONS RELATIVES A DES SYSTEMES DE COMMUTATION
Abstract
(EN)
A switching system (10) including a first signal emitter (11) and a second signal emitter (13) and a detector or sensor (12) which is adapted to detect or sense the signals. If the signal emitted by the second emitter (13) is 180 degrees out of phase with the signal emitted by the first emitter (11), the signal of the first emitter (11) is effectively cancelled such that no output is provided from the detector or sensor (12).
(FR)
Système de commutation (10) comprenant un premier émetteur de signaux (11) et un second émetteur de signaux (13) ainsi qu'un détecteur ou capteur (12) conçu pour détecter ou capter lesdits signaux. Si le signal émis par le second émetteur (13) présente un déphasage de 180 degrés par rapport au signal émis par le premier émetteur (11), le signal de ce dernier est effectivement annulé de sorte qu'aucune sortie ne soit générée par le détecteur ou capteur (12).
