摘要： A method and system adjusts blade tip clearance between rotating aircraft gas turbine engine blade tips and a surrounding shroud in anticipation of and before an engine command that changes an engine rotational speed. The method may include determining when to begin adjusting the tip clearance by expanding or contracting the shroud before the engine command and may be based on monitored aircraft and/or aircraft crew data indicative of the engine. The aircraft and/or aircraft crew data may include communications between aircraft crew and air traffic control authorities or air traffic control surrogates. Determining when to begin adjusting the tip clearance may include using learning algorithms which may use the aircraft gas turbine engine's operating experience and/or operating experience of other jet engines on an aircraft containing the aircraft gas turbine engine and/or on other aircraft.

摘要： Hot rail car bearings or wheels are identified by sensing an infrared radiation from the hot surface and determining whether features of the sensed signals are indicative of hot rail car surfaces. The features may include the signals themselves, with distances or correlations being established between the signals and signals of known hot bearings or wheels. The features may be analyzed in a feature or decision space, with boundaries being established that identify hot bearings or wheels, or that establish false positive features or noise. The identification may also be implemented as a matched filter.
