20080283680 | HOT RAIL WHEEL BEARING DETECTION SYSTEM AND METHOD - 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. | 11-20-2008 |

The system includes a sensor for sensing an infrared radiation radiating from the hot surface and a high pass filter to eliminate low frequency components from the sensor signal. The system also includes an absolute value module to compute absolute values of a filtered signal, a first comparator to compare output of the absolute value module to a first threshold and a peak detector to report a peak value of the sensor signal's output. The system further includes a second comparator to compare output of peak detector to a second threshold. | 11-20-2008 |
20090037035 | AIRCRAFT GAS TURBINE ENGINE BLADE TIP CLEARANCE CONTROL - 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. | 02-05-2009 |
20090076873 | Method and system to improve engineered system decisions and transfer risk - A method and system are provided to improve industrial engineered systems such as oil well drilling decisions and transfer risk. The method and system each include an interactive decision-support planning tool that aids a user as to how to select a portfolio of engineered systems and entities that the systems will process such as aircraft engines and flights, rigs and reserves, apparatus configuration, apparatus inspection, apparatus on line sensors, dynamic operations decisioning for the apparatus and drill path or asset dispatching and a contractual incentive to allocate risks to stakeholders best positioned to abate them. The decision support will reduce a fleet's financial risk associated with the cost of operations below that achievable without using the interactive decision-support planning tool and/or increase financial return associated with the cost of activity above that achievable without using the interactive decision-support planning tool, such that the financial risk and/or financial return are allocated in a desired manner among a plurality of operations stakeholders. | 03-19-2009 |

20140188777 | METHODS AND SYSTEMS FOR IDENTIFYING A PRECURSOR TO A FAILURE OF A COMPONENT IN A PHYSICAL SYSTEM - A computer-implemented system for identifying a precursor to a failure of a particular type of component in a physical system is provided. The physical system includes sensors coupled to the physical system. The computer-implemented system includes a computing device, a database, a processor, and a memory device. The memory device includes historical data including sensor measurements. When instructions are executed by the processor, the processor receives the historical data from the memory device. The processor generates a predictive model. The predictive model uses, as inputs, sensor measurements in the historical data. The predictive model is able to differentiate between sensor measurements taken before the repair event and those taken after the repair event without a time of the repair event being an input to the predictive model. The processor designates at least one sensor measurements used as inputs to the predictive model as precursors to the failure of the component. | 07-03-2014 |
