Title (EN) PROXIMITY DETECTION
(FR) DÉTECTION DE PROXIMITÉ
Abstract:
(EN) An electronic device (1) such as a cell phone, or a proximity detector for an electronic device (1), has an ultrasound transmitter (5), an ultrasound receiver (6), and a processing system. It transmits an ultrasonic sine-wave signal from the transmitter (5), and receives the ultrasonic sine-wave signal, through air, at the receiver (6). It detects when the frequency of the transmitted signal and a frequency of the received signal satisfy a predetermined difference criterion, and uses this to determine whether to disable or enable a touch or touchless input (2) on the device (1).
(FR) Cette invention concerne un dispositif électronique (1) tel qu'un téléphone cellulaire ou un détecteur de proximité pour un dispositif électronique (1), comprenant un émetteur d'ultrasons (5), un récepteur d'ultrasons (6) et un système de traitement. Il transmet un signal d'onde sinusoïdale ultrasonore à partir de l'émetteur (5), et reçoit le signal d'onde sinusoïdale ultrasonore, à travers l'air, au niveau du récepteur (6). Il détecte lorsque la fréquence du signal transmis et une fréquence du signal reçu satisfont un critère de différence prédéterminé, et s'en sert pour déterminer s'il faut désactiver ou activer une entrée tactile ou sans contact (2) sur le dispositif (1).
