  • Patent number: 12478896
    Abstract: An evaporator is provided for evaporating water from an ambient body of water having a water surface. The evaporator includes a housing that has a proximal end proximate to the water surface, a distal end distal to the water surface, and a housing air flow channel directed toward the water surface. The housing is disposed on a support, such as a float assembly, that positions the housing above the water surface. The evaporator also includes an air flow induction device, preferably an impeller, disposed to direct an air flow stream from the distal end toward the proximal end through the housing air flow channel and toward the water surface so that the air contacts the water. The impeller preferably is made of a fiberglass material. The support preferably includes at least one float assembly air flow channel that receives the air flow stream from the housing and directs it outwardly from the evaporator.

  • Patent number: 9235413
    Abstract: In semiconductor wafer manufacturing, processes such as analyzing test data associated with semiconductor wafers, interpreting the test data analysis, and acting on the test data interpretation and analysis are automated. Such automation can eliminate delays that were previously imposed by the action of test analysis engineers and wafer fabrication personnel, thereby reducing the amount of useless material that is produced before a process defect can be detected.

  • Patent number: 7826915
    Abstract: A system and method is disclosed for providing automatic qualification intervention in a manufacturing process that is performed by a plurality of components. At least one qualification process is associated with each of the components. The qualification processes are stored in a component/qualification matrix in a computerized database management system. The automatic qualification intervention system requires that all qualification processes for a component must be performed in conformity with the qualification processes for the component that have been stored in the component/qualification matrix. The automatic qualification intervention system significantly reduces the delays that are inherent in prior art methods.

  • Publication number: 20060171336
    Abstract: A multi-conference unit (MCU) (2) is arranged to compress a video stream in the horizontal direction to adjust the aspect ratio prior to onward transmission to an endpoint (6-1 to 6-4). By arranging for an endpoint to de-compress the video stream by a similar amount, widescreen video streams may be transmitted and viewed using generally legacy equipment. The use of a widescreen transmission provides additional opportunities for effective layouts of windows in a composed video stream with excessive distortion or clipping.
