Abstract: Introduced here are computer programs and associated computer-implemented techniques for achieving high-fidelity color reproduction in the absence of any known reflectance spectrums. That is, high-fidelity color reproduction can be achieved without portable references, such as gray cards and color checkers. To accomplish this, a new reference spectrum—the “reference illuminant spectrum”—is introduced into scenes to be imaged by image sensors. The reference illuminant spectrum is created by a multi-channel light source whose spectral properties are known.

Abstract: A open end wrench tool with a rotating wrench head having multiple openings of different sizes and a method of locking and releasing with a setting motion the rotating wrench head. A wrench tool that can be quickly changed to different sized wrench openings sized to fit hydraulic, oil, and water and fuel line fittings, generally known as AN (Air Force-Navy) fittings.

Abstract: A novel system for introducing a combustible liquid fuel into a gasoline combustion engine to obtain substantially perfect combustion and thereby prevent pollution, which system comprises heating means for elevating the temperature of the liquid gasoline fuel above its critical temperature, thereby converting it to its gaseous state; pressure means for providing a positive pressure as the liquid fuel is transported to the heating means; and means for discharging and rapidly expanding the gaseous fuel into the mixing chamber of the engine where it is admixed with air to provide a combustible mixture for burning and operation of the engine, the pressure means providing a pressure sufficient to maintain the fuel in its gaseous state immediately after it is discharged from the heating means into the mixing chamber.
