Abstract: This invention is for an innovative magnetic air separator (MAS) for delivering oxygen-enriched air or near-pure oxygen to for advanced combustion, coal gasification, industrial processes, and medical applications. In the MAS of the subject invention, input air is drawn into a large array of microchannels immersed in a strong, spatially varying magnetic field. Magnetic forces accelerate the paramagnetic O2 molecules within the microchannel flow and in a direction perpendicular to it, thus forming enriched and depleted streams. Such streams are then physically separated and subsequently combined according to their level of O2 enrichment or depletion. Highly enriched streams are repeatedly subjected to the magnetic separation process until the targeted level of O2 concentration is reached in selected streams. Partially enriched streams are recycled and fed back into the process feedstock air, while depleted streams are vented from the process.

Abstract: The invention is for an apparatus and method for a fuel injector enabling improved combustion in automotive engines. In one embodiment of the invention, fuel is preheated for greatly improved atomization and evaporation, especially during cold engine start. As a result, harmful pollution is greatly reduced pollution. In addition, alcohol-based automotive fuel may be used in cold ambient conditions. The invention overcomes the limitations of current electrically heated injectors and fuel rails having large thermal inertia and long preheat times. In another embodiment of the invention, optically-driven acoustic waves assist in atomization of injected fuel, thus resulting in reduced engine emissions and improved efficiency. Other applications include production of finely atomized fluid sprays for the manufacture of substrates for industry, applications of coatings, formation of uniform-sized particles for the production of pharmaceutical products, and thin-film deposition techniques for forming resistors, capacitors and other components.

Abstract: The present invention provides a solid-state lighting fixture and lamp for down light for use in applications especially in recessed lighting. In particular, the lamp of the subject invention may be configured as a direct screw-in replacement for common R-30 style incandescent flood lamp and it may be used existing luminaires. In one preferred embodiment of the present invention, a lamp mounted in a recessed light luminaire for down lighting has one or more light emitting diodes (LEDs) that are thermally coupled to a heat sink having fins for cooling by ambient air. The fins are configured so that air warmed by the fins can rise inside the luminaire and transfer its heat to it. Air cooled by the luminaire is allowed to sink and may flow out of the luminaire via a gap between the heat sink and the luminaire. Fresh cooler air may be drawn in between the fins to replace out-flowing air. This process of heating and cooling of air established a natural convection flow. Natural convective air flow allows for efficient thermal communication between the heat sink and the luminaire, thereby allowing for lower LED junction temperature and longer LED lifetime.

Abstract: An autonomous water source for extracting water from ambient air and delivering it to a plant to support growth. The system is based on an adsorption-desorption-condensation cycle using a sorption material to extract moisture from ambient air and condensing the water vapor driven off from the sorption material by subsequent heating and followed by condensation. Liquid condensate produced in this process on the condenser is collected and delivered by gravity to a plant to reduce thermal stress and to support growth. The invention provides a sustainable source of irrigation water for agriculture and forestry, including areas where no water resources exist or are not economically viable. It can be tailored in size, and therefore, output capacity, reflecting the desired water requirements of a particular application, and can be used to replace most agricultural situations now reliant on surface water drip feed systems. The device is simple, rugged, invulnerable to rain, snow, and freezing conditions, and can be designed to last for many years without service as there are few moving parts and power required for operation is provided by sunlight.

Abstract: An adhesive sheet is disclosed including a flexible substrate and an adhesive layer formed on at least one of the main surfaces of the flexible substrate. The adhesive sheet further includes a plurality of microscopic holes connecting the opposing surfaces of the sheet and being generally perpendicular to them. Such adhesive sheet is permeable by air and allows good bubble escapability when the sheet is applied to an article. Sufficient permeability of the sheet to air is achieved with microscopic size holes installed in modest areal densities, hence the appearance and functionality of the film surface are not significantly adversely impacted. One intended use of the subject invention is for tinting films used to reduce light transmission in windows for use in buildings and automobiles. In this application visual appearance of the film is paramount. Another intended application of the subject invention is for antireflective film which is applied to electronic computer displays (flat panel, cathode ray tube) to reduce unwanted ambient light reflection and to improve contrast.

Abstract: A cooling system for use in with a transmissive optical element of a high average power laser (HAP). The system includes at least one optically transmissive element (TOC) that is held by a differential pressure in thermal contact with a heat sink assembly. In one embodiment, the heat sink assembly includes an optically transparent heat conductor (THC) attached to at least one face of the TOC. A vacuum formed between adjacent faces of the TOC and THC urges the facing planar surfaces into thermal contact with one another. Waste heat generated in the TOC is conducted to the THC. The temperature gradient inside the TOC is maintained substantially parallel to the direction of a laser beam being directed through the THC so that a given phase front of the beam exposes TOC material to the same temperature. As a result, the TOC does not perturb the phase front of the laser beam.

Abstract: A supercharged internal combustion engine system wherein the supercharger assembly includes an ejector pump driven by high-pressure air for pumping intake air into engine combustion chamber. Included are means for sensing engine power demand and controlling the supercharging action. A compressor and an air tank for providing high-pressure air for driving the ejector pump are also disclosed. During periods of natural aspiration the ejector pump can be by-passed to reduce flow impedance. The ejector pump can use a driving nozzle with a fixed throat or a variable throat, or a lobed nozzle. Effective supercharging is achieved even at low engine speeds. One of the objects of the invention is to obtain more power from small displacement ICE and thus providing automotive vehicles with sufficient acceleration in addition to good fuel economy.

Abstract: A solid-state laser system includes a solid-state laser having a laser gain medium and at least one pumping diode. The system also includes a thermal management system capable of placing a coolant in thermal communication with the solid-state laser such that the coolant can carry heat away from the solid-state laser. The thermal management system is then capable of rejecting the heat carried away by the coolant to a fluid at an ambient temperature, where the coolant can be at a temperature between 40° C. and 80° C. when the thermal management system rejects the heat. Advantageously, the thermal management system of the present invention can include reject the heat to a fluid comprising, for example, air or water. As such, the thermal management system does not require separate cooling of the fluid carrying the heat away from the coolant.
