Abstract: A modular electronic cooling system with moving parts, composed of a base unit and individual modules inserted into this base unit in respect to the expected upper limit of the heat load may utilize thermoelectric power generation and the heat load itself to allow for operation independent of any external power source. By the same mechanism the cooling system scales within a range automatically reacting to and dissipating a dynamic heat load via forced convection, and doing so passively, without the need for specific programming. This cooling system uses porous material or multi-layered mesh parts, thermoelectric components, a modular assembly system and independent enclosure parts for described porous material or multi-layered mesh, an electronics control system that may be passively activated, and a motor assembly. Altogether the system provides maximum efficiency in terms of form factor.

Altogether the system provides maximum efficiency in terms of form factor.

Abstract: An closed single-loop low-energy/energy-independent cryocooler that removes high quantities of heat from a large area while utilizing a design that allows multiple temperatures on multiple cooled areas in parallel to allow for use on complex electronics which have different preferred operating temperatures. An energy independent design is a simple TEG based variation of the standard invention design. Said system allows for different uses such as for the cooling of over-clocked computer systems working at high heat loads, superconducting circuits, and/or the efficient cooling of temperature dependent devices such as laser diodes and etc.

Abstract: An energy efficient cryocooler is disclosed that cools a large area with multiple cooling temperatures on multiple cooled area working in parallel for the maximum cryogenic cooling and “over-clocking” of microprocessors and computer components using liquid and/or gaseous refrigerants in phase change. A cryogenic cooling system provides simultaneous steady stream (or pulse) cryocooling of a computer components with each part of the computer system receiving cooling at it's optimum temperature. The system comprises an evaporator with liquid and gaseous refrigerant which evaporator is placed onto the microprocessor to disperse heat from said microprocessor and a enclosure around the cooled system that cools all other components in one stage. The use of the invented cryocooling system resulted in the increase 2.4 GHz “Celeron D” microprocessor frequency to 4.78 GHz. The RAM was also overclocked to 60 MHz above normal on a test system.

Abstract: An image projection system includes a bright light source of polarized light, and in one form of the invention, a spatial light modulator, having an alignment layer, to modulate the polarized projection light, wherein the bright polarized light source is aligned with the alignment layer to permit the polarized light to pass therethrough without the need for unwanted light blocking polarizers. The spatial light modulator generates output light representative of the image, which is projected by a projection lens system onto a remote viewing surface to form a bright image thereon. In another form of the invention, three different colored images are each produced by three separate polarized light sources illuminating three individual light valves, and are superimposed to produce a full color image while all three light sources are maintained fully activated to provide a brightly illuminated image.

Abstract: An optical input arrangement and method includes an optical device for sensing a projected image and for detecting the presence of a high intensity optical input signal light by discriminating it from the entire projected image and the ambient light reflecting from a viewing surface. A determination is made as to when the differences in intensity of sequentially measured pixel intensity values of the light reflected from the viewing surface exceeds a positive threshold amount and substantially immediately thereafter decreases more than a negative threshold amount, to facilitate an even more precise discrimination between the input signal image and the overall projected image. An alignment device generates an optical signal for facilitating the alignment of the arrangement to capture the entire image reflecting from the viewing surface.

Abstract: A low profile liquid crystal projector unit, and a novel method of using it to project a liquid crystal image with substantially no keystoning effects. An optics arrangement directs high intensity light within the housing along an irregularly shaped light path extending angularly through an angularly inclined liquid crystal display panel offset by an angle .lambda. relative to the normal axis plane of the display panel to help reduce image keystoning. An output mirror mounted above the housing is inclined angularly opposite to the liquid crystal display panel and cooperates with a lens set for projecting reflectively a liquid crystal image, formed by the display panel, onto a remote surface. The output mirror is mounted to reflect the liquid crystal image upwardly at an angle .theta. to the normal axis plane of the remote viewing surface, where the angle .lambda. and the angle .theta. are substantially equal to help reduce image keystoning.
