Title
(EN) PULSE CONTROL FOR ULTRASONIC TOOL SYSTEMS
(FR) COMMANDE D'IMPULSIONS DE SYSTÈMES D'OUTIL À ULTRASONS
Abstract
(EN) Systems and methods for controlling vibrations of a tip of an ultrasonic instrument. A maximum ultrasonic energy level for the ultrasonic instrument is determined, and a minimum ultrasonic energy level for the ultrasonic instrument is determined based on the maximum ultrasonic energy level. An AC drive signal is then sourced to the ultrasonic instrument that induces ultrasonic energy in the tip of the ultrasonic instrument including several ultrasonic energy pulses. The ultrasonic energy pulses peak at the determined maximum ultrasonic energy level and are interspaced by significant periods at the determined minimum ultrasonic energy level.
(FR) L'invention concerne des systèmes et des procédés de commande de vibrations d'une pointe d'un instrument à ultrasons. Un niveau d'énergie ultrasonore maximal de l'instrument à ultrasons est déterminé, et un niveau d'énergie ultrasonore minimal de l'instrument à ultrasons est déterminé sur la base du niveau d'énergie ultrasonore maximal. Un signal de pilotage de CA est ensuite émis à destination de l'instrument ultrasonore qui induit une énergie ultrasonore dans la pointe de l'instrument ultrasonore comprenant plusieurs impulsions d'énergie ultrasonore. Les impulsions d'énergie ultrasonore sont maximales au niveau d'énergie ultrasonore maximal déterminé et sont espacées les unes des autres par des périodes significatives au niveau d'énergie ultrasonore minimal déterminé.
