Abstract: An optical system for a digital light projection system is provided. The optical system comprises a plurality of LED arrays, wherein each LED array comprises a plurality of LEDs. The optical system also comprises an optical concentrator element positioned substantially adjacent to each of the LED arrays, wherein each concentrator element reflects light emitted from the plurality of LEDs within the corresponding LED array so as to provide substantially uniform light at an output surface of each concentrator element. The optical system preferably further comprises an optical combiner element, wherein the output surface of each concentrator element is optically aligned with a corresponding side of the combiner element, and wherein the combiner element chromatically combines the substantially uniform light provided at the output surface of each concentrator element so as to form color-combined light at an output surface of the combiner element.

Abstract: An optical system for a digital light projection system is provided. The optical system comprises a plurality of LED arrays, wherein each LED array comprises a plurality of LEDs. The optical system also comprises an optical concentrator element positioned substantially adjacent to each of the LED arrays, wherein each concentrator element totally internally reflects light emitted from the plurality of LEDs within the corresponding LED array so as to provide substantially uniform light at an output surface of each concentrator element. The optical system preferably further comprises an optical combiner element, wherein the output surface of each concentrator element is positioned substantially adjacent to a corresponding side of the combiner element, and wherein the combiner element spatially combines the substantially uniform light provided at the output surface of each concentrator element so as to form substantially white light at an output surface of the combiner element.

The optical system also comprises an optical concentrator element positioned substantially adjacent to each of the LED arrays, wherein each concentrator element reflects light emitted from the plurality of LEDs within the corresponding LED array. The optical system preferably further comprises a reflective aperture element positioned substantially adjacent to the output surface of each concentrator element. The aperture element includes a reflective surface and an aperture defined by the reflective surface. The reflective surface faces the output surface of each corresponding concentrator element to thereby ultimately provide substantially uniform light which is projected through the aperture.

Abstract: A control mechanism includes an optically transparent member, a knob with a reflective surface, an optical light source, and an optical receiver. The optical light source directs light toward the knob that is reflected to the optical receiver.

Abstract: A process for producing amide derivatives represented by general formula (XV) ##STR1## or enantiomers thereof, novel intermediate compounds useful for producing these compounds, etc., and a process for producing the same, wherein each symbol is as defined in the specification. Compared with the conventional processes, the above process can be very easily effected and enables an efficient production of the compounds (XV), i.e., those involving the compounds (XVI) having an HIV protease inhibitory effect in high yields. The novel intermediates are highly advantageous as intermediates for producing not only the above compounds (XVI) but also those which are useful as an X-ray contrast medium, etc.
