  • 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.

  • Patent number: 10845343
    Abstract: A process is disclosed in which a computing device reads electronic data from an ultrasonic scanning probe and processes that data in real time to determine if any potential weld defects are encountered as the probe head moves along scanning the weld. The method receives weld scan data in the form of scanning slices and determines if any of the encountered indications match a predetermined criterion. The process utilizes a moving scan data window of scan slices and processes each window for indications of weld defects. The processing of the data window is optimized using a rule-based, indications counting set so that any found defect indications triggers the issuance of a signal to an operator, in various forms, such as activating a marking module, issuing an alert signal, or printing a report.

  • Patent number: 10641745
    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.

  • Patent number: 10624610
    Abstract: An existing ultrasonic diagnostic device is used to obtain a color flow image of a target object whose stiffness is to be measured. At this time, a vibration exciter applies a micro vibration with a frequency of n/4 (n represents an odd number equal to or larger than 1) to the target object with respect to a burst frequency of an ultrasonic pulse to generate a shear elastic wave. As a result, a striped pattern corresponding to the stiffness of the target object caused by the shear elastic wave appears on a display of the ultrasonic diagnostic device as a shear elastic wave detection image.

  • Patent number: 10508974
    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.
