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 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.

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.
