Abstract: An optical-based sensing apparatus and method are provided. A sensing apparatus (10) may include a tube (30). An optical fiber (12) may be encased in the tube. A buffering layer (14) may be interposed between the optical fiber and the tube. The buffering layer and/or the tube may be selectively configured to form along a length of the apparatus a plurality of optical sensing zones (16, 18, 20) spatially arranged to sense parameters involving different parameter modalities.

Abstract: A method and system for cooling a heat-generating component are provided. The system includes a heat generating electronic component including a heat conductive face, a heat sink device including at least one open face pin fin array surface directly coupled to the conductive face, each fin including a distal end including an outwardly facing contact area, the contact areas covering only a portion of the conductive face, the contact areas configured to carry electrical current therethrough, and an immersion of dielectric fluid contained in a vessel, the vessel including a heat-conductive hull at least partially submerged in a heat sink fluid.

Abstract: A computer-implemented maintenance/repair workscope development tool uses one or more sources of gas turbine engine/fleet operational condition data, gas turbine engine/fleet historical data and gas turbine engine/fleet specific information, including other historical, statistical and maintenance/engineering records data to develop a recommended maintenance/repair workscope. A method, system and program product are described for producing a recommended maintenance/repair workscope for individual machines and/or machines on a fleet level. Relevant domain knowledge/information models along with appropriate application rules defining maintenance/repair requirements are predetermined and maintained in a network accessible database/repository. A rules/reasoner engine is used to develop logical inferences and make intelligent workscope choices based upon user input situational data, operational condition data stored in data/information databases and the predetermined knowledge/information models and rules.
