    Abstract: An ultrasonic transducer having a piezoelectric element for use on a vehicle is disclosed. The transducer has a control and evaluation circuit for generating a control voltage for the piezoelectric element, which generates and emits an ultrasonic signal based on the control voltage, and for outputting an output signal on the basis of an echo signal received at the piezoelectric element. A gyrator circuit is included for providing a compensation inductance for adapting the control and evaluation circuit, for compensating for a parasitic connection capacitance of the piezoelectric element. The gyrator circuit has a variable compensation inductance. A method for compensating for an ultrasonic transducer having a piezoelectric element for adapting a reception sensitivity is also disclosed. The method involves recording a measurement variable for adapting the reception sensitivity, and compensating for the ultrasonic transducer by changing the compensation inductance of the gyrator circuit based on the recorded measurement variable.

    Abstract: The infrasound generating device based on a displacement-feedback type vibration exciter comprises a displacement-feedback type vibration exciter system, an infrasound generating chamber (3) and a laser vibrometer (1); the displacement feedback mechanism is adopted in the vibration exciter (2). The piston (31) is driven by the vibration exciter to move in a sinusoidal manner in the cavity (35) of the airtight infrasound generating chamber (3) and the standard infrasonic pressure signal with low harmonic distortion can be achieved. The displacement of the moving part (22) of the vibration exciter (2) can be measured by the laser vibrometer (1) through the measurement beam (15) injecting into the vibration exciter (2) through the optical channel running through the vibration exciter and the standard infrasonic pressure can also be obtained. The value of the standard sound pressure produced by the infrasound generating chamber is calculated. Such value is used as the calibration reference for the infrasound sensors (4) to be calibrated in order to achieve the primary calibration of the infrasound sensors. The standard infrasonic sensor can be installed inside the infrasound generating chamber (3) and the output of the standard infrasonic sensor can be used as the reference for the infrasonic sensor (4) to be calibrated in order to achieve the secondary calibration of the infrasound sensors. This invention has the advantages of technical maturity, high feasibility, easy to realize, high calibration accuracy and so on.

    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. In so doing, the thermal performance of the transducer improves by allowing an increase in the duration and level of the transducer excitation voltage.
