Abstract
An electromagnetic digitizer system employing an interleaved array of individual conductors each in a W configuration bent into plural sections to define plural parallel portions distributed in different segments of a tablet such that each section comprises a center conductor portion connected in series with outer parallel portions such that the current in the center conductor portion splits or divides among the outer conductors and also flows in the opposite direction. Each of the plural sections defines two tablet coarse positions for a pointing device. Interpolation is employed to determine a fine position.
