Assignee:

General Electric Company - Nishayuna NY

International Classification:

H01L 27/146

US Classification:

25037009

Abstract:

A dual function detector device operates in either a normal operating mode or in an EMI correction mode to suppress effects of EMI within the detector. The detector device may be a flat panel x-ray detectors used in x-ray imaging systems. The device has a pixel architecture and panel read-out technique that enables real-time, high spatial frequency measurement of noise induced by electromagnetic radiation on a digital x-ray detector. The measurement can be used to calibrate the detector in real-time to attain artifact-free imaging in all environments, including those that contain temporally and spatially changing electromagnetic fields.

F02C 3/30
F02C 3/04

Abstract:

A combined water-wash and water injection cooling system for a gas turbine engine including a water delivery system, an air delivery system, and a controller configured to couple to the gas turbine engine, the water delivery system, and the air delivery system to access and execute one or more routines. The water delivery system includes one or more spray nozzles to spray water upstream and directly in front of a compressor of the gas turbine engine. The air delivery system is configured to provide air from the compressor to the water delivery system so that the one or more spray nozzles spray atomized water into the compressor of the gas turbine engine during a cooling mode to cool the compressor. During an on-line water wash mode, air from the air delivery system to the water delivery system is turned off to enable the one or more spray nozzles to spray non-atomized water into the compressor of the gas turbine engine to wash the compressor.
