#$%^&*AU2016201414B220180208.pdf#####BATTERY POWERED HAND-HELD ULTRASONIC SURGICAL CAUTERY CUTTING DEVICE ABSTRACT A method for controlling a transducer and generator assembly (303), comprising: receiving a current signal from a battery assembly (301); generating a transducer input signal based on the current signal; providing the transducer input signal to a transducer (902); receiving a motional feedback signal corresponding to mechanical motion of the transducer (902); amplifying the motional feedback signal according to a first gain level, thereby generating a first amplified motional feedback signal; determining whether a magnitude of the first amplified motional feedback signal is greater than a low gain threshold; and if it is determined that the magnitude of the first amplified motional feedback signal is greater than the low gain threshold, amplifying the motional feedback signal according to a second gain level lower than the first gain level, thereby generating a second amplified motional feedback signal.
