Abstract

A distance R to be measured is derived by measuring the spacing xm between a fixed transmitter Tx and a movable receiver Rx, and comparing this with the reference spacing xref between a fixed transmitter Tx’ and receiver Rx. Each spacing is measured by passing a large number of pulses sequentially from receiver to transmitter through a.coupling medium, the receipt of one pulse triggering transmission of the next. The spacing is derived from the time Ttaken to pass n pulses; preferably n is fixed and T is measured.
