Title (EN) A PIEZOELECTRIC MEMS DEVICE FOR PRODUCING A SIGNAL INDICATIVE OF DETECTION OF AN ACOUSTIC STIMULUS
(FR) DISPOSITIF MEMS PIÉZOÉLECTRIQUE PERMETTANT LA PRODUCTION D'UN SIGNAL INDIQUANT LA DÉTECTION D'UN STIMULUS ACOUSTIQUE
Abstract:
(EN) A device comprising: a sensor; and a first circuit configured to detect when an input stimulus to the sensor satisfies one or more detection criteria, and further configured to produce a signal upon detection that causes adjustment of performance of the device; and a second circuit for processing input following detection, wherein the second circuit is configured to increase its power level following detection, relative to a power level of the second circuit prior to detection.
(FR) L'invention concerne un dispositif comprenant : un capteur ; et un premier circuit conçu pour détecter quand un stimulus d'entrée vers le capteur satisfait un ou plusieurs critères de détection, et conçu en outre pour produire un signal après une détection provoquant un réglage des performances du dispositif ; et un second circuit de traitement d'entrée après la détection, le second circuit étant conçu pour augmenter son niveau de puissance après la détection, par rapport à un niveau de puissance du second circuit avant la détection.
