ABSTRACT:
A distance measuring system includes a device for detecting ringing signals (false echoes) generated by ultrasonic transducers used to generate probe signals and detect echoes of the probe signals to determine the distance of an external object from the measurement system. The absence or duration of ringing signals are determined, and the display of the distance measuring system is operated accordingly. False indications of distance measurements are limited by storing a number of distance measurements in a memory, and selecting the measurement most likely to indicate the presence of an object from which the distance to the measuring system is determined.
