22、rdance with the principles of this invention by providing distance measuring apparatus which includes a reference unit and a measuring unit. the reference and measuring units are the same and each includes an electroacoustic transmitter and an electroacoustic receiver. the spacing between the transm

23、itter and the receiver of the reference unit is a fixed reference distance, whereas the spacing between the transmitter and receiver of the measuring unit is the distance to be measured. in each of the units, the transmitter and receiver are coupled by a feedback loop which causes the transmitter to

24、 generate an acoustic pulse which is received by the receiver and converted into an electrical pulse which is then fed back to the transmitter, so that a repetitive series of pulses results. the repetition rate of the pulses is inversely related to the distance between the transmitter and the receiv

25、er. in each of the units, the pulses are provided to a counter. since the reference distance is known, the ratio of the counter outputs is utilized to determine the desired distance to be measured. since both counts are identically influenced by temperature and humidity variations, by taking the rat

35、ent of arrival of an echo is defined as the first moment the echo signal surpasses that threshold. the intensity of an echo reflecting from an object strongly depends on the objects nature, size and distance from the sensor. further, the time interval from the echos starting point to the moment when

36、 it surpasses the threshold changes with the intensity of the echo. as a consequence, a considerable error may occur even two echoes with different intensities arriving exactly at the same time will surpass the threshold at different moments. the stronger one will surpass the threshold earlier than
