Title: Innovations of Ivan Karlsson in Optical Touch Systems
Introduction
Ivan Karlsson is a notable inventor based in Lund, Sweden. He has made significant contributions to the field of optical touch systems, holding a total of five patents. His work focuses on enhancing touch sensing technology, which has applications in various electronic devices.
Latest Patents
One of Karlsson's latest patents is an optical touch system that comprises means for projecting and detecting light beams above and inside a transmissive panel. This invention provides a touch sensing apparatus that includes a light transmissive element defining a touch surface. A set of emitters is arranged around the periphery of the touch surface to emit beams of light into the light transmissive element. A first portion of the beams propagates inside the light transmissive element while illuminating the touch surface, causing an attenuation of the propagating light when an object touches the surface. Additionally, a second portion of the beams passes out of the light transmissive element and is reflected to travel above the touch surface. The system also includes a set of light detectors arranged around the periphery of the touch surface to receive light from the emitters and from above the touch surface, with each light detector configured to receive light from more than one emitter.
