  • Process and system for measuring the distance of a moving body from a fixed part
    Patent number: 6614239
    Abstract: A process and a system for measuring the distance of a moving body (12) from a fixed part (10), characterized the steps of: generating a first alternating signal (r(t)) having a frequency within the radio-wave range or elastic-wave range; emitting the first signal from the fixed part towards the moving body (12); receiving the first signal (r(t)) on the moving body (12) and generating, on the moving body (12), a second signal (s(t)) having a frequency (nf) equal to the frequency of the first signal (r(t)) multiplied by a constant factor (n), the second signal (s(t)) having an initial phase (&phgr;1) equal to the phase (2&pgr;ft1+&phgr;) at the instant (t1) in which it is received by the moving body (12); generating, on the fixed part, a third signal (u(t)) having a frequency (nf) equal to the frequency of the second signal (s(t)) and an initial phase (&phgr;0) equal to the initial phase of the first signal (r(t)); and determining the variation in distance of the moving body (12) in a pre-set time interva
