摘要： Diffuse image measurement system and digital image formation method. The system includes a source of light with time-varying intensity directed at a scene to be imaged. A time-resolved light meter is provided for receiving light reflected from the scene to generate time-resolved samples of the intensity of light incident at the light meter. The temporal variation in the intensity of light incident at the light meter is associated with a function of a radiometric property of the scene, such as a linear functional of reflectance, and a computer processes the samples to construct a digital image. The spatial resolution of the digital image is finer than the spatial support of the illumination on the scene and finer than the spatial support of the sensitivity of the light meter. Using appropriate light sources instead of impulsive illumination significantly improves signal-to-noise ratio and reconstruction quality.

摘要： Leak detection system. The system includes a structure sized to fit within a pipe for supporting at least one sensing element near an inside wall of the pipe, whereby a pressure gradient at a leak in the pipe will cause the sensing element to respond. Structure is provided for detecting movement or deformation of the sensing element, the movement or deformation indicating the presence of a leak. In a preferred embodiment, the structure includes two spaced-apart rings for supporting the at least one sensing element. The sensing element is a diaphragm in a preferred embodiment. In this embodiment, the sensing element is supported for movement with respect to the ring structure which includes sensing circuitry for detecting the movement to indicate a leak. Other embodiments employ different sensing elements that respond to pressure gradients near leaks.

摘要： Fuel management system for efficient operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder of the engine. A fuel management microprocessor system controls injection of the anti-knock agent so as to control knock and minimize that amount of the anti-knock agent that is used in a drive cycle. It is preferred that the anti-knock agent is ethanol. The use of ethanol can be further minimized by injection in a non-uniform manner within a cylinder. The ethanol injection suppresses knock so that higher compression ratio and/or engine downsizing from increased turbocharging or supercharging can be used to increase the efficiency or the engine.

摘要： Method for making a patterned thin film of an organic semiconductor. The method includes condensing a resist gas into a solid film onto a substrate cooled to a temperature below the condensation point of the resist gas. The condensed solid film is heated selectively with a patterned stamp to cause local direct sublimation from solid to vapor of selected portions of the solid film thereby creating a patterned resist film. An organic semiconductor film is coated on the patterned resist film and the patterned resist film is heated to cause it to sublime away and to lift off because of the phase change.

摘要： System for pipeline rehabilitation. The system includes repairing a leak in a pipe using a pair of substantially semi-cylindrical parts connected through a compliant joint. When the parts are compressed, the semi-cylindrical parts form a cylinder whose outside diameter is less than the inside diameter of a pipe with a defect thereby allowing the cylinder to be inserted into the pipe at a location of a leak. Once in place, the parts engage the inside surface of the pipe when the compression is released thereby to seal the leak.
