Title: Bruce T Freedman: Innovator in Optical Touch Technology

Introduction

Bruce T Freedman is a notable inventor based in Cary, NC (US). He has made significant contributions to the field of optical touch technology. His innovative approach has led to the development of a unique patent that addresses challenges in touch panel devices.

Latest Patents

Freedman's most recent patent is titled "Laser touch panel reflective surface aberration cancelling." This invention presents a method and apparatus that effectively distinguish a valid touch from optical aberrations caused by unwanted objects or scratches on the light plane of an optical touch panel device. During a training mode, the device learns the relative position of 'aberration dropouts' caused by these unwanted objects. In normal operating mode, it generates and compares the relative positions of 'touch and aberration dropouts' to differentiate between the two signals. The touch dropout signals undergo further processing to determine the precise location of a touch, while the aberration dropout signals are discarded. This innovative solution enhances the accuracy and reliability of touch panel devices.
