ABSTRACT:
A system is disclosed for converting the location and movement of a manually controlled instrument into corresponding electrical signals. The manually controlled instrument responds to the phase and frequency of an electrical field that varies to represent position information on an orthogonal writing grid. A single, phase-locked loop is utilized to produce both a first signal corresponding to the instrument location along an x-axis and a second signal corresponding to the instrument location along a y-axis. The first and second signals both represent the differential between pairs of related absolute signals. The differential signals are independent of normal signal variations and other error sources. The field is generated by first selecting sets of conductors that are positioned orthogonally with respect to each other. Signals are then applied to the respective sets of conductors to thus generate an electric field at the location of the intersection of the orthogonal sets.
