Abstract
A control system for providing a drive signal to an ultrasonic transducer and for controlling the tip motion of the ultrasonic transducer wherein the transducer tip is disposed in a hemolyzing chamber. The control system includes a sensor for sensing the motion of the transducer tip and a feedback circuit coupled between the sensor and the transducer where the feedback circuit provides a feedback signal to control the motion of the transducer tip.
