Abstract
A pointer position detection system for use in determining the position of a pointer relative to a tablet comprising a signal generating system coupled to the tablet for transmitting a driving signal, the signal generating system including a set of conductors for radiating the driving signal and the driving signal including information as to the particular conductor being activated by the signal generating system, a movable pointer responsive to the transmitted driving signal, the pointer including a signal processor responsive to the information and the amplitude of the driving signal on a selected plurality of successive conductors for generating a positional signal and causing the positional signal to be transmitted a selected time after receipt of the information and the amplitudes and further including a transmitter system coupled to the signal processor for transmitting the positional signal, and a signal detector system for detecting the transmitted positional signal.
