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: A method for amplifying an echo signal, in which an analog echo signal suitable for detection of a vehicle's surroundings is amplified by a gain dependent on the transit time of the echo signal, the analog echo signal being amplified by an amplifier having a plurality of outputs, each having a different gain, and a downstream A/D converter having a time-variable reference voltage. In the process, there is a switch between the different outputs of the amplifier at predefined switching points in time, and the reference voltage of the A/D converter varies over time between the switching points in time in such a way that the echo signal is present at the output of the A/D converter with a transit time-dependent total gain having a predefined characteristic.

Abstract: A multi-mode pulsed radar method for sensing or measuring a product material in a storage tank includes providing a measure of radar signal attenuation for pulsed radar signals transmitted to the product material. Automatic adjustment of one or more transmitted radar pulse parameters is implemented by selecting a pulse width and a pulse amplitude based on the measure of radar signal attenuation. In signal mode 2 higher amplitude and/or wider pulses are selected when the measure of radar signal attenuation is relatively high and in signal mode 1 lower amplitude and/or narrower pulses are selected when the measure of radar signal attenuation is relatively low. The radar pulse is transmitted to the product material using the selected pulse width and the pulse amplitude. The target signal reflected or scattered from the product material is processed to determine at least one parameter, such as product level.

Abstract: Methods, systems and device are provided for improving the range and accuracy of proximity measurement such as in ultrasonic sensing systems. In particular, the blind zone caused by reverberation signals can be reduced or eliminated by attenuating signals received during the time period corresponding to the blind zone without. In an implementation, an attenuator circuit is selected by a switch to process received signals during the blind zone time period and deselected by the switch after the time zone time period. Additionally, the accuracy and range of the measurement can be improved by varying the gain provided to the received signals based on the varying measuring distance. In an implementation, a gain-adjustable amplifier is controlled by a gain control signal to provide incremental gain as time increases.
