  • Patent number: 11455445
    Abstract: A method is provided for non-intrusively determining cross-sectional variation of a fluidic channel. The method includes creating a pressure pulse in a fluidic channel using a hammer to strike an external surface of a fluidic channel. The method also includes sensing, by one or more sensors, reflections of the pressure pulse; and obtaining, from the one or more sensors, a measured pressure profile based on the sensed reflections of the pressure pulse. A forward model of cross-sectional variation of the fluidic channel is generated based on a baseline simulation. Using the forward model, a simulated pressure profile is generated. Using the measured pressure profile and the simulated pressure profile, an error is determined. When the error is outside a predetermined threshold, the forward model is updated based on the error. An estimate of cross-sectional variation of the fluidic channel based on the forward model is displayed.

  • Patent number: 11380452
    Abstract: NDE probes provide unique data signals from a remote object such that can be used to accurately and precisely locate a position. With a computer processor, the data signals are converted into a positional fingerprint that is compact and easily analyzed as a file or information of probe position. The positional fingerprint is stored in association with the position or object to verify a same position at another time. Another probe detects other data signals for the object at another time. Under a similar transformation into a positional fingerprint, the position of the other probe can be matched to the first by comparing positional fingerprints. The comparison may use a probabilistic comparison and/or compare several different fingerprints from several different locations and times to ensure a best match. Position verification between probes may ensure a repair has been completed in the proper location, verify system integrity or investigate potential problems.

  • Patent number: 11002641
    Abstract: A statistical method is used to separate periodic from non-periodic vibration peaks in autocorrelation spectra. Generally, an autocorrelation spectrum is not normally distributed because the amplitudes of periodic peaks are significantly large and random relative to the generally Gaussian noise. In a normally distributed signal, the statistical parameter kurtosis has a value of 3. The method sequentially removes each largest amplitude peak from the peaks in the spectrum until the kurtosis is 3 or less. The removed peaks, which are all considered to be periodic, are placed into a set. The total energy of the peaks in the set is considered to be the total periodic energy of the spectrum. As the process of building the peak set proceeds, if its total energy becomes greater than or equal to a predefined energy threshold before its kurtosis reaches 3 or less, the process stops and the periodic peak set is defined.

    Abstract: A method is disclosed to extract meta-data held in a weld scan data file and from such data determine whether the testing data is acceptable for review. A series of configuration parameters held in the scan data file are analyzed for inconsistencies and a select set of parameters are reviewed for codes and industry accepted standards compliance with recorded scan data. Additional qualitative tests may be implemented on the scan test file and unacceptable results may also provide guidance to the weld inspector as to whether continued review of the scan data file is worthwhile. Such consistency testing avoids wasteful activities reviewing a flawed weld scan data file and provides signals to operators to avoid the processing of such a file by weld scan analysis software when such processing will not result in successful assistance to a weld inspector.

    Abstract: A “store on alert” vibration data acquisition mechanism uses scalar data produced by a vibration monitoring device as a predicate to capturing and storing analytical vibration data in the vibration monitoring device. The scalar data may consist of scalar process variables generated in the vibration monitoring device that are acquired at a fixed interval, such as PeakVue and Overall Vibration. At each interval, these scalar data values are compared to machine performance threshold levels, such as ADVISE, MAINT and FAIL, to determine whether analytical vibration data is to be stored separately inside the vibration monitoring device. Since the analytical vibration data is captured based on a predicate inside the vibration monitoring device (i.e., comparison of the scalar value to the thresholds), the analytical vibration data includes more relevant diagnostic information about a specific machine performance event.

  • Patent number: 10421151
    Abstract: Apparatus and methods for measuring the temperature of a substrate are disclosed. The apparatus includes a source of temperature-indicating radiation, a detector for the temperature-indicating radiation, and a decorrelator disposed in an optical path between the source of temperature-indicating radiation and the detector for the temperature-indicating radiation. The decorrelator may be a broadband amplifier and/or a mode scrambler. A broadband amplifier may be a broadband laser, Bragg grating, a fiber Bragg grating, a Raman amplifier, a Brillouin amplifier, or combinations thereof. The decorrelator is selected to emit radiation that is transmitted, at least in part, by the substrate being monitored. The source is matched to the decorrelator such that the emission spectrum of the source is within the gain bandwidth of the decorrelator, if the decorrelator is a gain-driven device.

  • Patent number: 10386336
    Abstract: An apparatus for detecting anchor bolt pullout strength. The apparatus includes circuitry configured to process ultrasonic measurement signals using at least one of a direct, an indirect, and a semi-direct measurement technique. Further, the apparatus comprises a first probe and a second probe connected to the circuitry, and memory for storing data detected by the first and the second probe.

  • Patent number: 10309772
    Abstract: Chirp waves generated in a transmitting/receiving unit is supplied to ultrasonic sensors. Signals output from the ultrasonic sensors are supplied to the transmitting/receiving unit and summed in a signal processing/recording unit. The signal processing/recording unit performs mutual correlation processing between the summed signals and the chirp waves and calculates a peak generation time difference. Necessity of exchanging a pipe is determined by calculating and recording the thickness of a pipe from the calculated time difference and calculating a difference between thicknesses measured in the past and the present.

  • Patent number: 10073063
    Abstract: A hollow structure like a pipeline is inspected using an array of ultrasound transmitters located within the hollow structure distributed over different radial directions from a center of the array. Parameters such as ellipticity, defining a shape and/or orientation of an inner surface of a wall of the hollow structure are first determined based on measured delays between transmission of ultrasound pulses from the transmitters to reception of first reflections of those ultrasound pulses. Parameters may be used that define an elliptically shaped cross-section of the inner wall surface for example. Next an ultrasound wavefront composed of joint transmissions from the transmitters along at least a sector of the array is transmitted, using relative time delays between waves transmitted by the respective ones of the transmitters to compensate for estimated differences between travel times from the transmitters to the shape defined by the parameters. Reflections of the joint transmissions are detected.
