Title: Touch screen based upon topological mapping with resistance framing design
Inventor: RITCHIE RUFUS
IPC: G06F3/041
Filed: 1999-03-12
Abstract: A new touch screen is based upon the mapping of coordinates from an equipotential space defined by a simple set of screen electrodes to some other, more useful coordinates, such as Cartesian.  The key idea is that unique coordinate mapping can be achieved with each sensing pair of electronic readings. A new sensor is described with a band of intermediate conductivity framing the sensor area.  This sensor can be used advantageously either as a standalone with uniform equipotential distributions or in connection with the mapping concepts discussed herein with non-uniform distributions.
