ABSTRACT:
A technique for sensing the relative position of a cursor or other indicator integral with an inductive sensing element along at least one coordinate of a specified area is described. An array of conductors are sequentially arranged along the coordinate and are sequentially excited by a sequence of adjacent, substantially rectangular voltage pulses to yield an overlapping current distribution to simulate a continuous travelling-wave magnetic field along the coordinate. The induced voltage response of the sensing element is a continuous wave form which passes through a predetermined level at a time, relative to the start of movement of the travelling wave magnetic field, that is indicative of the relative position of the element along the coordinate. A threshold detector element which outpulses an indication upon the attainment of such specified value of induced voltage response is coupled, along with a signal indicative of the start of excitation of the conductors, to suitable digital comparison circuitry to yield a position read-out of the system.
