Title (EN) FEEDBACK CONTROL SYSTEM FOR ULTRASOUND PROBE
(FR) SYSTEME RETROACTIF DE COMMANDE D'UNE SONDE A ULTRASONS
Abstract: front page image
(EN)A control system for a probe, including a transmission member, comprises a power source for supplying a constant power to a transmission member and a transducer for coupling the constant power to the transmission member and for providing a mechanical output to the transmission member at a frequency. A frequency measuring device is also provided for constantly measuring the frequency of the mechanical output of the transducer. A current monitoring device for measuring current forwarded to the transducer which monitors the current while the frequency of said mechanical output is varied until it is determined at what frequency the current is at a maximum is also provided. A method for implementing this apparatus is also provided.
(FR)L'invention porte sur le système de commande d'une sonde comportant un élément de transmission, une alimentation fournissant une puissance continue à l'élément de transmission, et un transducteur reliant la puissance continue à l'élément de transmission et fournissant une puissance mécanique à l'élément de transmission selon certaines fréquences. L'invention porte également sur un dispositif de mesure de fréquence mesurant en continu la fréquence de la puissance mécanique fournie au transducteur, sur un ampèremètre mesurant le courant fourni au transducteur et suivant le courant alors que varie la fréquence de la puissance mécanique jusqu'à ce qu'on détermine pour quelle fréquence le courant passe par un maximum, et sur un procédé de mise en oeuvre dudit appareil.
