  • Patent number: 8965728
    Abstract: A method is disclosed for providing a real time, radial exhaust temperature distribution in a gas turbine to improve the understanding of exhaust gas temperature in a manner similar to installing production rakes. The thermocouples are installed along the exhaust frame strut skins at a number of radial positions. The data from the thermocouples along each of the struts is used to produce a normalized radial profile of the turbine exhaust temperature. The existing turbine station instrumentation is then used to expand the normalized profile into an actual profile of the turbine exhaust temperature. The calculations/transfer functions for temperatures are obtained from data collected during performance testing with full rakes. This profile is integrated to determine a bulk Tx to improve gas turbine controls including model-based controls or corrected parameter controls (MBC/CPC) controls, or specific radial temperatures are used, to provide protective action for bucket platforms, or other turbine components.

  • Patent number: 8920026
    Abstract: In one embodiment, a current sensing circuit corrects for the transient and steady state temperature measurement errors due to physical separation between a resistive sense element and a temperature sensor. The sense element has a temperature coefficient of resistance. The voltage across the sense element and a temperature signal from the temperature sensor are received by processing circuitry. The processing circuitry determines a power dissipated by the sense element, which may be instantaneous or average power, and determines an increased temperature of the sense element. The resistance of the sense element is changed by the increased temperature, and this derived resistance Rs is used to calculate the current through the sense element using the equation I=V/R or other related equation. The process is iterative to continuously improve accuracy and update the current.

  • Publication number: 20140278200
    Abstract: A method and system for determining a temperature of a working gas passing through a passage to a turbine section of a gas turbine engine. The method includes identifying an acoustic frequency at a first location in the engine upstream from the turbine section, and using the acoustic frequency for determining a first temperature value at the first location that is directly proportional to the acoustic frequency and a calculated constant value. A second temperature of the working gas is determined at a second location in the engine and, using the second temperature, a back calculation is performed to determine a temperature value for the working gas at the first location. The first temperature value is compared to the back calculated temperature value to change the calculated constant value to a recalculated constant value. Subsequent first temperature values at the first location may be determined based on the recalculated constant value.

    Abstract: Methods and apparatus are provided for fast item identification. A plurality of sensors capture data for an unknown item that is moved past the sensors. The data is processed to produce a plurality of physical attributes related to the unknown item. The physical attributes are used to search a database of physical attributes for a large number of known items where the unknown item is one of the known items. A small set of known items are selected where the physical attributes of the known items match the physical attributes of the unknown item. Further processing of the selected set of known items identifies the unknown item as one of the set of known items.

  • Patent number: 8825342
    Abstract: The system for mitigating an overspeeding condition of a turbine engine can include a sensor for measuring an actual speed of a gas generator turbine of the turbine engine and a processor for deriving a delta, the delta being a comparison between the actual speed of the gas generator turbine and a predicted gas generator turbine speed. The system is configured for detecting the overspeeding condition when delta is higher than a predetermined threshold. A method of detecting an overspeeding condition during operation of a turbine engine can include measuring an actual speed of a gas generator turbine, then evaluating a delta between the actual speed of the gas generator turbine and a predicted speed of the gas generator turbine, then comparing the delta to a threshold value.

    Abstract: A measurement method for a junction-to-case thermal resistance is provided. First, a first transient cooling curve of the chip for the semiconductor device under test (DUT) without grease is measured. Then a second transient cooling curve of the chip for the DUT with grease is measured. A difference ?T of temperature variations of the two transient cooling curves with and without grease is calculated. The temperature of a constant temperature cold plate for fixing the semiconductor DUT is increased by ?T, and a third transient cooling curve of the chip for the DUT with grease is measured again. The first transient cooling curve and the third transient cooling curve are used to calculate the junction-to-case thermal resistance.

  • Patent number: 8812170
    Abstract: A container data center includes a cooling control system. The cooling control system reads a temperature of a container of the container data center and a direction of wind flowing across the container, and determines whether a first or a second cooling device of the container data center needs to be turned on according to the read temperature. The cooling control system further determines whether the read wind direction is the same to a direction of hot air expelled by the turned on cooling device. When the read wind direction is not the same as a direction of hot air expelled by the turned on cooling device, the cooling control system turns off the turned on cooling device, and turns on the other cooling device.
