摘要： A method for estimating a trend in exhaust gas temperature in a turbine engine includes sampling exhaust gas temperature and a plurality of variables associated with the exhaust gas temperature over a set of observation times for a turbine engine to acquire exhaust gas temperature data. A trend in the exhaust gas temperature for the specific turbine engine is identified by removing the effect of the plurality of variables on the exhaust gas temperature data.

摘要： A fluid detector for determining a presence of a fluid within a container includes a piezoelectric element that outputs a first ultrasonic signal in response to an input electrical signal and a lens with an upper portion and a lower portion. The piezoelectric element is coupled to the upper portion of the lens so that, when the lens is disposed adjacent the outer surface of the wall such that the lens is intermediate the piezoelectric element and the wall, the lens focuses the first ultrasonic signal toward the wall so that the first ultrasonic signal enters the wall.

摘要： An improved ultrasonic mechanical sector scanning transducer assembly is disclosed. An ultrasonic transducer is disposed for movement within a generally tubular housing. A drive element extends longitudinally within the housing and is coupled for transmitting motion to the transducer. Power means produces oscillatory rotative movement of the drive element and transducer. A diaphragm seal, comprising a resilient tubular membrane, provides a liquid tight seal between longitudinally displaced interior sections of the housing. The tubular membrane has one relatively narrow end and flares along its length to a wider opposite end. The narrow end is bonded about the drive element. The wider end is affixed about the periphery of the housing. A coaxial cable is coupled to the transducer and extends to the exterior of the housing. The cable is wrapped within a spiral groove extending about the outer surface of a spool or reel mounted for movement in unison with the transducer.
