Introduction

Brian G Lim is a notable inventor based in Vancouver, Canada. He has made significant contributions to the field of touch-sensing technology, holding 2 patents that showcase his innovative approach to enhancing user interaction with devices.

Latest Patents

One of his latest inventions is the "Lattice Touch-Sensing System." This invention is directed to a lattice touch-sensing system for detecting the position of a touch on a touch-sensitive surface. The system includes two capacitive sensing layers, separated by an insulating material, where each layer consists of substantially parallel conducting elements. The conducting elements of the two sensing layers are substantially orthogonal to each other. Each element may comprise a series of diamond-shaped patches connected together with narrow conductive rectangular strips. A control circuit is included to provide an excitation signal to both sets of conducting elements and to determine the position of the touch based on the affected bars in each layer.

Another significant patent is the "Capacitive Touch Sensor Architecture with Unique Sensor Bar Addressing." This capacitive touch sensor features symmetrical electrical interconnections for use with a touch sensor of a device. The touch sensor includes several sensor bars, each coupled to a unique pair of lead lines, with no inter-connection between individual sensor bars. The sensor bars may be substantially transparent and comprise indium tin oxide. This touch sensor can be disposed on a viewing screen or proximate thereto, providing a signal for determining a touch location based on the modulation of the electrical field caused by the touch.
