Title (EN) MULTI-MODE ULTRASONIC SYSTEM
(FR) SYSTÈME ULTRASONIQUE MULTIMODE
Abstract:
(EN) In one embodiment, an apparatus comprises a switching mechanism to switch an input line between a first input voltage and a second input voltage, apulse generator coupled to the switching mechanism to generate an electronic pulse train at a high frequency in response to the first input voltage and an electronic pulse train at a low frequency in response to the second input voltage, an oscillator circuit coupled to the pulse generator to receive the electronic pulse train, and an ultrasonic transmitter coupled to the oscillator circuit to produce an ultrasonic signal at a frequency that is a function of a frequency of the electronic pulse train.
(FR) Dans un mode de réalisation, un appareil comporte un mécanisme de commutation destiné à commuter une ligne d'entrée entre une première tension d'entrée et une deuxième tension d'entrée, un générateur d'impulsions couplé au mécanisme de commutation de manière à produire un train d'impulsions électroniques à une fréquence élevée en réponse à la première tension d'entrée et un train d'impulsions électroniques à une fréquence faible en réponse à la deuxième tension d'entrée, un circuit d'oscillateur couplé au générateur d'impulsions de manière à recevoir le train d'impulsions électroniques, et un transmetteur ultrasonique couplé au circuit d'oscillateur de manière à produire un signal ultrasonique fonction d'une fréquence du train d'impulsions électroniques.
