    Abstract: An ultrasonic probe includes a plurality of ultrasonic transducers. The ultrasonic probe is connected to a reception system circuit including at least one first delay adder circuit in which a predetermined number among the plurality of ultrasonic transducers is configured as one subarray and delaying and adding are performed in subarray units with respect to an ultrasonic wave reception signal that is acquired from the ultrasonic transducers included in the subarray, and a second delay adder circuit in which delaying and adding are performed with respect to the ultrasonic wave reception signal that is acquired from the ultrasonic transducers. The plurality of ultrasonic transducers include a first group which transmits the reception signal to the second delay adder circuit passing through the first delay adder circuit and a second group which transmits the reception signal directly to the second delay adder circuit without passing through the first delay adder circuit.

    Abstract: In one embodiment, a method for determining the voltage current phase relationship of a piezoelectric phacoemulsification handpiece generally includes the steps of obtaining an analog AC voltage signal corresponding to the operating AC voltage of a piezoelectric handpiece along with an analog AC current signal corresponding to the operating AC current of the piezoelectric handpiece. Using reference detection circuits, a digital voltage signal and a digital current signal is produced. A synchronous sample clock is taken that has a frequency that is 2N times faster than the frequency of the operating ultrasonic handpiece (i.e., driving frequency), where N is the number of digital bits allocated to the sample clock.. This clock measures the time between onsets of a voltage and current cycle. This time value equates to the phase time delta between the two signals. Dividing the synchronous sample clock to obtain the driving frequency ensures the signals are synchronous. Further dividing the end count value into 360° results in the phase shift between the two signals in degrees that is independent of the operating frequency.

    Abstract: Phacoemulsification apparatus includes a phacoemulsification handpiece having a needle and an electrical system for ultrasonically vibrating said needle along with a power source for providing pulsed electrical power source for providing pulsed electrical power to the handpiece electrical system. Irrigation fluid is provided to the handpiece needle and aspirating fluid is removed from the handpiece needle and aspirating fluid is removed from the handpiece needle. A determination of a voltage current phase relationship of the provided electrical power is made and in response thereto a control system varies a power level duty cycle provided to the handpiece electrical system from the power source and/or modify the aspiration flow rate. In addition, a separate input enables manual control of pulse amplitude and the control system in response to a selected amplitude determines a duty cycle of the provided pulsed electrical power.
