    摘要： A method and apparatus for measuring a predetermined parameter having a known relation to the transit time of movement of an energy wave through a medium according to International Application PCT/IL00/00241, published 9 November 2000 as International Publication No. WO 00/67013, wherein the transmitted and received cyclically-repeating energy wave is an electromagnetic carrier wave amplitude-modulated by a cyclically-repeating electromagnet modulating wave. The received amplitude-modulated carrier wave is demodulated, and the fiducial point of the demodulated wave is utilized to change the frequency of the modulating wave such that the number of received demodulated waves is a whole integer. According to a further feature, the received demodulated wave may be shifted by a whole-integer multiple of 360( before being utilized to change the frequency of the modulating wave, in order to add an artificial distance to the measurement, e.g., when a relatively high frequency is used and thereby a relatively small wavelength is involved, or when otherwise there is a relatively short transit distance between the transmitter and the receiver.

    摘要： A method and apparatus for measuring the force applied by a first member 25 coupled to a second member 26 by a connecting body 6 by transmitting a cyclically-rrepeating energy wave through the connecting body from a first location thereon to a second location thereon, measuring the transit time of the cyclically-repeating energy wave from the first location to the second location and utilizing the measuring transit time to produce a measurement of the force. In the preferred described embodiment, the connecting body is a fastening plate 6 which fastens a drive shaft 3 to a driven shaft 5 and measures the torque output of the drive shaft.
