Abstract
L'invention concerne un transducteur ultrasonore comportant une membrane et un contenant muni d'une base et d'au moins un élément formant paroi. Ce transducteur ultrasonore peut comprendre un côté attaque et un côté tension de polarisation. Un premier dispositif de commande peut comporter un nombre de lignes de sortie supérieur au nombre de lignes d'entrée d'un second dispositif de commande. Le premier dispositif de commande peut recevoir un signal de commande du transducteur ultrasonore et transmettre une première partie de ce signal de commande au premier processeur, la longueur de cette première partie étant inférieure ou égale au nombre de lignes d'entrée du second processeur. Un ensemble de transducteurs ultrasonores peut être commandé de manière à produire un faisceau orientable. L'orientation de faisceau peut être déviée par des retards de tamponnage dans la distribution d'un signal d'horloge.
