Abstract: The invention provides a controller (1) for a high-frequency agitation source, the controller comprising signal generation means (3) for generating a drive signal (53) having a variable duty cycle. The drive signal (53) is used to drive the high-frequency agitation source (2). The controller further comprises temperature detecting means (7) for detecting a temperature of the high-frequency agitation source (2). Further, the controller (1) is adapted and arranged to vary the duty cycle of the drive signal (53) in response to the temperature of the high-frequency agitation source (2). By varying the duty cycle of the drive signal (53), the average power supplied to the piezoelectric crystal (2) can be varied whilst still maintaining a fixed amplitude of oscillation. This allows the temperature of a high-frequency agitator, for example a piezoelectric crystal, to be controlled.

The annunciating signal generating circuit (5) is equipped with a signal generating circuit (57) for sound which generates the intermittent first actuating signal that is repeatedly turned on and off at regular time intervals, a signal generating circuit (58) for vibration which generates the intermittent second actuating signal that is repeatedly turned on and off at regular time intervals, and a synchronous circuit (56) which shifts the turning-on periods of the first and second driving signals generated from the circuits (57) and (58) from each other.

Abstract: A method for determining the voltage current phase relationship of a piezoelectric phacoemulsification handpiece includes the steps of obtaining an AC voltage signal corresponding to the operating AC voltage of a piezoelectric handpiece and obtaining an AC current signal corresponding to the operating AC current of the piezoelectric handpiece. From said AC current signal, onset of a current cycle is determined and after onset of the current cycle, a voltage (VI) corresponding to a time necessary for the AC current signal to reach a maximum value is produced. Also, after onset of the current cycles, a voltage (Vv) corresponding to a time necessary for the AC voltage signal to reach a maximum value is produced. Using an A/D converter, a digital output (Dv) corresponding to (Vv) is produced and a digital output (DI) corresponding to (VI) is produced. Comparing (Dv) and (DI) determines the phase relationship between the voltage and current of the piezoelectric phacoemulsification handpiece.
