  • Patent number: 7428906
    Abstract: A method for cleaning a stationary gas turbine unit during operation, wherein the unit comprises a turbine, a compressor driven by the turbine, the compressor having an inlet, an air inlet duct arranged upstream of the air inlet of the compressor, the inlet duct having a part of the duct adjoining the inlet of the compressor and having decreasing cross section in the flow direction in order to give the air flow a final velocity at the inlet to the compressor. A spray of cleaning fluid is introduced in the inlet duct. The cleaning fluid is forced through a spray nozzle with a pressure drop exceeding 120 bar to form a spray the drops of which have a mean size that is less than 150 ?m. The spray is directed substantially parallel to and in the same direction as the direction of the air flow.

  • Patent number: 7430291
    Abstract: The present invention provides termination for transmission line structures propagating common mode signals. Common mode signals typically represent noise in systems wherein information is transmitted as differential mode signals. The present invention terminates the common mode signals in a dynamically matched termination that prevents or significantly reduces reflection of said common signals without interference with differential mode transmission lines or their normal operation. Application is shown for an unshielded, twisted pair transmission line as commonly used in telephony-based systems for both voice and broadband data communication. The methods for application of the present invention to systems with large numbers of conductors are also shown.

  • Patent number: 7423527
    Abstract: A bidirectional radio frequency identification (RFID) network system and method are presented. The system allows users to configure, monitor, and manage different sensor devices by using a graphical user interface real-time. The reconfiguration is done through a network management computer at the top system level that receives user input, generates code images according to the user input, and appropriately routes the code images to sensor routers that directly control the sensors. If the system is multi-layered, some code images are also sent to the intermediate-level network management computers. The system allows users to not only monitor a business flow but react to problematic situations quickly by adjusting the workflow. The aspect-oriented nature of the system allows users to reconfigure the system based only the Functionality aspects without worrying about the Partitioning aspects (e.g., how the network and the sensors are physically connected).
