摘要： A light engine combines light of first, second, and third color ranges using three pentagonal prism elements. Each prism has first and second diagonal surfaces. Each first diagonal surface has a first dichroic treatment and each second diagonal surface has a second dichroic treatment. The prisms are arranged with the first diagonal surface of the first prism juxtaposed with one diagonal surface of the third prism and with the second diagonal surface of the second prism juxtaposed with the other diagonal surface of the third prism. A first light beam of the first color is reflected at a right angle by the first diagonal surfaces, and a second light beam is reflected at a right angle by the second diagonal surfaces. A third light beam of the third color passes unreflected through the surfaces to produce a combined light beam or common output light path.

摘要： A control panel system has a projection screen with an inside surface for being illuminated to produce a graphical display and with an outside surface accessible to a user. An illumination source projects radiation to illuminate the projection screen, wherein the radiation includes visible radiation and infrared radiation. An optical distribution system distributes the visible radiation according to an image for the graphical display and distributes the infrared radiation according to a predetermined pattern, wherein the projection screen transmits the infrared radiation out from the outside surface where it can be reflected back toward the optical distribution system by a manually-controlled object that is placed by the user in relation to the image. An infrared sensor receives the reflected infrared radiation from the optical distribution system and generates a detection signal identifying the location of the manually-controlled object in response to the predetermined pattern.
