    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. This constitution can prevent the abrupt increase of the power consumption of the annunciator.

    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.
