Pointer position detection system using a signal processor in the pointer

A pointer position detection system for use in determining the position of a pointer relative to a tablet comprising:

• signal generating means coupled to said tablet for transmitting a driving signal;
• movable pointer means responsive to said transmitted driving signal, said pointer means including signal processor means responsive to said driving signal for processing information contained in said driving signal and for generating a processed signal indicative thereof and further including transmitting means coupled to said signal processing means for transmitting said processed signal, said signal generating means including a set of conductors for radiating said driving signal, three adjacent conductors being utilized to enable information pertaining to the particular conductor being activated by said signal generating means, information pertaining to the condition of said pointer means and information pertaining to the position of said pointer to be sequentially transmitted;
• and
• signal detecting means for detecting said transmitted processed signal.
