Title (EN) LOW POWER ACOUSTIC APPARATUS AND METHOD OF OPERATION
(FR) APPAREIL ACOUSTIQUE BASE PUISSANCE ET PROCÉDÉ DE FONCTIONNEMENT
Abstract:
(EN) In accordance with one aspect of the disclosure, a method of operating an acoustic system including detecting an ultrasonic sound signal and pattern matching the received ultrasonic sound signal to determine when the received ultrasonic sound signal is a desired ultrasonic sound signal. The method includes sending a signal to at least one electronic component when the received ultrasonic sound signal is the desired ultrasonic sound signal. The method includes operating the microphone in a lower power state when the received ultrasonic sound signal is not the desired ultrasonic sound signal.
(FR) Selon un aspect de l'invention, celle-ci concerne un procédé de fonctionnement d'un système acoustique consistant à détecter un signal sonore ultrasonique et un motif correspondant au signal sonore ultrasonique reçu pour déterminer si le signal sonore ultrasonore reçu est un signal sonore ultrasonique voulu. Le procédé consiste à envoyer un signal à au moins un composant électronique lorsque le signal sonore ultrasonique reçu est le signal sonore ultrasonique voulu. Le procédé consiste à faire fonctionner le microphone à un état de basse puissance lorsque le signal sonore ultrasonique reçu n'est pas le signal sonore ultrasonique voulu.
