Abstract
The present invention relates to a microprocessor-controlled ultrasonic control apparatus used to sweep a range of operating frequencies and to identify, store and tune to the resonant frequency of a magnetostrictively driven handpiece. This allows the user to change tip systems as desired and the device is not limited to a preset or switch selectable frequency. The unit automatically finds and adjusts to the frequency which corresponds to the resonant acoustic frequency of the magnetostrictive coil insert tip system.
