Latest Patents

David I Dunthorn holds a patent for a touch-sensitive screen with improved corner response. This invention features a resistor electrode type of gradient sheet designed for a touch sensor that minimizes ripple and bow of equipotential lines along the edges and corners. The technology utilizes orthogonal electrical fields on a resistive surface to accurately determine the coordinates of a selected position. The design incorporates T-shaped electrodes of specific lengths and spacing to effectively eliminate the bow of the equipotential fields. Each electrode connects to a designated point along a resistor chain positioned along the edges of the resistive surface, providing selected voltages. Additionally, the gradient sheet includes corner electrodes connected to corner junctions of the resistor chains, enhancing the sensor's linear work area compared to prior art.
