  • Patent number: 8942462
    Abstract: A method to automatically quantify dendrite arm spacing in dendritic microstructures. Once a location of interest in a cast material specimen has been identified, the information contained in it is automatically analyzed to quantify dendrite cell size information that is subsequently converted into a quantified dendrite arm spacing through an empirical relationship or a theoretical relationship. In one form, the relationship between DCS and DAS is such that the DAS in dendritic structure of cast aluminum alloys may be automatically determined from the measurement of one or more of dendrite cell size and the actual volume fraction of the eutectic phases in the local casting microstructure. Non-equilibrium conditions may be accounted for in situations where a theoretical volume fraction of a eutectic phase of the alloy in equilibrium condition is appropriately modified.

    Abstract: A method of calibrating an individual sensor of a particular sensor type whose output varies non-linearly with at least one measured quantity and at least one operating condition. The first step includes producing a set of calibration curves for each sample sensor of the particular sensor type. The resulting sets of calibration curves are then averaged and the results used to produce a generic calibration surface for the particular sensor type showing its variation. Individual calibration measurements are then taken for a number of different values of the measured quantity at a small number of discrete values. The individual calibration readings are then used to map the generic calibration surface to the individual calibration measurements of the individual sensor.

  • Patent number: 7788054
    Abstract: A scanner instrument used for scanning tubing that is being placed into an oil well or being removed from the oil well can be calibrated during retrieval of tubing from the well. Calibrating the tube scanner includes scanning a tubing standard and comparing the data from the standard scan to the known characteristics of the standard. The relationship between the scanned data and the known characteristics can be computed. The relationship between the scanned data and the known characteristics can be used as the calibration function for the scanner. Calibrating the tube scanner can also include scanning a string of tubing segments and then adjusting the data collected. The adjustment is based upon equalizing the data peaks that occur in the scan data at the coupling joints between tube segments.

  • Patent number: 7602923
    Abstract: An electro acoustic system built-in test and calibration method utilizes a built-in self-test module to send a test signal through a first circuit device to an audio transmitter, causing the audio transmitter to output a test signal, for enabling the test signal to be received by a audio receiver and then processed by a connected circuit device and converted into a feedback digital signal to the self-test module for comparing the linearity relative to the originally provided test signal so that the parameter values and conformity of circuit devices can be optimized subject to comparison result. The test and adjustment procedure is recycled for other parameter items, and a warning signal is produced when proper adjustment cannot be done.

  • Patent number: 7599805
    Abstract: A system for determining an acoustic signature of a device is disclosed that includes a computer processor operable to determine strength and location of shock wave sound signals based on propagation of sound waves generated by the device. The strength and location of the shock wave signals are modified due to dissipation and dispersion effects in a non-uniform atmosphere. The shock wave signals are separated into even and odd numbered signals, and oscillations in the signals are smoothed by averaging even and odd numbered shock signals.

  • Patent number: 7587291
    Abstract: A method for focusing broadband acoustic signals with flat spectral content based on Time-Reversed Acoustics (TRA) principle is disclosed. The method of the invention differs from the conventional TRA focusing in that it includes an additional step of adjusting the spectral content of time-reversed signal, prior to applying it to the radiating transducer. This additional step, which includes attenuation of the spectral components with high amplitude and amplification of the spectral components with low amplitude, leads to flattening of the spectra of the radiated signal and widening of its frequency band. TRA focusing with this additional step of adjusting spectral content of the radiated signal allows generation of shorter pulses and provides better concentration of acoustic energy than standard TRA focusing.

  • Publication number: 20080140331
    Abstract: A method of calibrating an individual sensor whose output varies with at least one operating condition. A generic calibration curve is produced for the variation of the sensor reading with the at least one operating condition for the particular sensor type of the individual sensor. Calibration readings are then taken for the individual sensor at just a small number of discrete values for the at least one operating condition which fall within the full range of operating values for the at least one operating condition for which the sensor is to be calibrated. Using the calibration readings, the generic calibration curve is then scaled in order to fit the generic curve to the individual sensor.
