Abstract

Described is an improved stylus design for an input device that uses resistive decoding technology (RDT). Such technology utilizes a graphics tablet or digitizer to enter position information for further storage, manipulation and display by a computer. The stylus must feel comfortable in the hand, and it must function well. This disclosed stylus design is unique in that it contains all the electronics (amplifier circuitry) and switch assembly in a package design that provides the necessary grounding and shielding to minimize spurious noise and effects by magnetic fields. The figure illustrates the design and components of the disclosed stylus.
