Title
(EN) DEVICE AND METHOD FOR PROXIMITY DETECTION BASED ON SOUND
(FR) DISPOSITIF ET PROCÉDÉ DE DÉTECTION DE PROXIMITÉ SUR LA BASE D'UN SON
Abstract
(EN) Devices and methods for proximity detection based on sound are provided. According to an embodiment, an acoustic probe includes a sound generator and an acoustic sensor, and at least one of the sound generator or the acoustic sensor is disposed within the dispense chamber portion. According to an embodiment, the liquid dispenser includes a sound generator and an acoustic sensor, and further includes one or more side conduits, where at least one of the sound generator or the acoustic sensor is disposed within a cavity of a respective one of the one or more side conduits, wherein the cavity and a connector of each of the one or more side conduits are free from resonance within a frequency range of the sound sensed by the acoustic sensor.
(FR) L'invention concerne des dispositifs et des procédés de détection de proximité sur la base d'un son. Selon un mode de réalisation, une sonde acoustique contient un générateur de son et un capteur acoustique, et le générateur de son et/ou le capteur acoustique sont disposés à l'intérieur de la partie chambre de distribution. Selon un mode de réalisation, le distributeur de liquide contient un générateur de son et un capteur acoustique, et contient aussi un ou plusieurs conduits latéraux, le générateur de son et/ou le capteur acoustique étant disposés à l'intérieur d'une cavité d'un conduit respectif parmi le ou les conduits latéraux, la cavité et un raccord du ou de chacun des conduits latéraux étant exempts de résonance dans une plage de fréquences du son détecté par le capteur acoustique.
