20100309169 | Optical Touch Screen with Reflectors - A touch panel including a generally planar surface, at least two illuminators, for illuminating a sensing plane generally parallel to the generally planar surface, at least one selectably actuable reflector operative, when actuated, to reflect light from at least one of the at least two illuminators, at least one sensor for generating an output based on sensing light in the sensing plane and a processor which receives the output from the at least one sensor, and provides a touch location output indication. | 12-09-2010 |
20090200453 | Optical Touch Screen Assembly - An optical touch panel including a support defining a detection region, an optical illumination assembly including at least two edge emitting optical light guides extending along adjacent portions of the detection region and having ends adjacent to one another and at least one mechanical coupling and optical coupling assembly, at least one sensor assembly, operative to detect changes in the light received from the optical illumination assembly produced by the presence of an object in the detection region and detection circuitry receiving at least one output from the at least one sensor assembly and providing an output indication of the two dimensional location of object impingement in the detection region. | 08-13-2009 |
