Abstract:
The invention relates to an ultrasonic measuring system ( 10 ), in particular for measuring distance and/or as a parking aid in vehicles, having an electroacoustic ultrasonic transducer ( 12 ) which has a oscillating element ( 14 ), does not have a voltage converter, can be alternately operated as an ultrasonic transmitter and an ultrasonic receiver and has a signal connection ( 16 ), which is used either as an input or as an output of the ultrasonic transducer ( 12 ), and an earth connection ( 18 ) which is connected to earth, and a control and evaluation unit ( 20 ) for exciting the oscillating element ( 14 ) of the ultrasonic transducer ( 12 ) to emit ultrasonic waves for operating the ultrasonic transducer ( 12 ) during a transmission interval for the purpose of subsequently deactivating the excitation of the oscillating element ( 14 ) and attenuating the latter during a decay phase and for receiving and processing ultrasonic waves in a reception interval. The control and evaluation unit ( 20 ) has a bridge circuit ( 28 ) which is connected to a DC supply voltage ( 80 ) and has controllable switches ( 30  to  40 ) and a charge storage capacitance ( 42 ), the polarity of which can be reversed and which is intended to alternately output a positive and a negative excitation voltage for the signal connection ( 16 ) of the ultrasonic transducer ( 12 ) during the transmission interval. The control and evaluation unit ( 20 ) outputs a voltage pulse of substantially 0 V at the end of the transmission interval for the signal connection ( 16 ) of the ultrasonic transducer ( 12 ).

Claim (Index 8):
The ultrasonic measuring system of  claim 7 , characterized in that the filter comprises a switchable filter constant for a faster decay of the mean decay signal at the signal terminal of the ultrasonic transducer during the decay phase.
