Abstract:

A two-dimensional digitizing system comprises a plurality of overlaid digitizer tablets. Each tablet includes two wire grid circuits oriented at right angles to each other for the X and Y directions, with each circuit having conductive grid structures. In those circumstances where two panels generate position signals, a controller verifies which of the competing position signals is correct. The digitizer is also characterized by a capability to operate at large stylus-tablet separations, allowing for a multi-layered laminate tablet of substantial thickness. The present system is readily adapted for applications such as a cloth cutting in which large surface areas are required and in which the digitizer tablet circuitry must be located remote from a cutting surface.
