Abstract: Components of an ultrasonic sensor are contained in a cylindrical casing having an end wall closing one end of the casing. A vibrator such as a piezoelectric element is disposed in the casing in contact with the end wall. An integrated circuit chip that includes a signal generator, a filter device and a temperature sensor is contained in the casing. Vibrations generated in the vibrator are transferred to the end wall that transmits ultrasonic waves. Ultrasonic waves received by the end wall are converted into electrical signals in the vibrator. Frequency of the transmitting signals and a frequency region of the signals to be received are controlled according to the ambient temperature, so that they always coincide with a resonant frequency of the end wall which changes according to the ambient temperature. Thus, high transmitting/receiving efficiency is always realized, irrespective of the ambient temperature.

Abstract: A method for diagnosing the health of a transducer may include transmitting a signal to a transducer to cause the transducer to transmit a stress wave into an object being monitored, wherein the signal has a predetermined frequency range or bandwidth. The method may also include receiving response data for the transducer and transforming the response data to data representative of an impedance curve of impedance versus frequency for the predetermined frequency range. The method may further include extracting selected parameters from the impedance curve to diagnose the health of the transducer.

Abstract: A method and system for controlling probe heating in an ultrasound system is disclosed. The method and system comprises electrically exciting a transducer within the probe; and detecting at least one pulse characteristic from the excited transducer. The method and system further includes analyzing at least one pulse characteristic to determine if the probe is coupling into a reflecting medium such as air or into tissue. Accordingly, a system and method in accordance with the present invention detects when an ultrasound transducer is coupling energy into a patient or into a reflecting medium such as air.

Abstract: A system and method for tuning and controlling ultrasonic handpieces by varying the frequency of the drive signal that is fed to the handpiece by a discrete dither increment. A digital signal processor may be used to measure the response of the handpiece to the varying drive signal and compare these responses to determine the probable value of the actual series resonance. The output of the digital signal processor is used to generate control parameters embodied within an appropriate control signal, which is fed to the source of the drive signal in order to alter aspects of the drive signal.

Abstract: A system is provided for applying ultrasound power to treat human tissue comprising a transducer driven by an oscillating signal from a power amplifier. The transducer and power amplifier have a power-conversion-efficiency characteristic which is a function of the frequency of the oscillating signal and the acoustic load on the transducer. Data sampling and frequency adjustment means are provided which continually monitor the current supplied to the crystal and adjust the frequency of the oscillating signal to maximize the power-conversion-efficiency of the transducer and power amplifier.

Abstract: A piezoelectric transducer frequency self-calibration system interrogates the transducer by driving it with various frequencies within a specified range while monitoring the transducer output power level. Two threshold frequency points are identified at which the output power level is at a predetermined threshold level less than the expected maximum output level, and the average of these two threshold frequencies is taken to be the optimum frequency.
