Patent number: 11933766Abstract: A material profile can be determined by assuming an elliptical or circular arc geometry and by using acoustic noise generated by diffuse internal reflection and/or specular reflection on the internal (ID) or external (OD) interface of the material under inspection, such as a pipe or curved plate. A non-destructive testing (NDT) technique can acquire acoustic data of the material using an ultrasonic signal. The acquired acoustic data can be filtered such that the acoustic noise generated by diffuse internal reflection and/or specular reflection is separated from any flaws in the material. Positions of the acoustic noise can be determined and then a regression technique can be applied to the positions, which can generate an equation of a circle, for example, such as to provide a radius and thickness of the pipe or curved plate.Type: GrantFiled: January 10, 2022Date of Patent: March 19, 2024Assignee: Evident Canada, Inc.Inventors: Nicolas Badeau, Benoit Lepage

Patent number: 11927437Abstract: Disclosed is a system and method for ultrasonic measurement of the average diameter and surface profile of a tube. A calibration block is used to calibrate the average tube diameter, and a correction is applied to account for any temperature difference of the couplant between calibration and test measurements. By using a linear probe, or a single probe with a finely pitched helicoidal scan, errors in diameter measurement due to presence of surface pits may be compensated.Type: GrantFiled: April 2, 2021Date of Patent: March 12, 2024Assignee: Evident Scientific, Inc.Inventors: Jinchi Zhang, Nicolas Badeau

Patent number: 11927565Abstract: Techniques for compensating a TFM delay computation live (e.g., during acquisition) as a function of the measured thickness along the scan axis of a probe of an acoustic inspection system. At various scan positions, the acoustic inspection system can measure the thickness of the object under test. With the measured thickness, the acoustic inspection system can compute the delays used for the TFM computation to reflect the actual thickness at that particular scan position of the probe.Type: GrantFiled: February 22, 2022Date of Patent: March 12, 2024Assignee: Evident Canada, Inc.Inventor: Nicolas Badeau

Publication number: 20230003695Abstract: A compression technique can be used for processing or storage of acquired acoustic inspection data. For example, data indicative of peak values of an A-scan time-series can be stored to provide a compressed representation of such time-series data. A representation of the original A-scan data can be reconstructed, such as using the data indicative of the peak values, and a digital filter. Such an approach can dramatically reduce a volume of data associated an acoustic acquisition, such as a Full Matrix Capture (FMC) acquisition to be used for Total Focusing Method (TFM) beamforming and related imaging.Type: ApplicationFiled: June 30, 2022Publication date: January 5, 2023Inventors: Nicolas Badeau, Guillaume Painchaud-April

Patent number: 11494873Abstract: Examples of the present subject matter provide techniques for calculating amplitude fidelity (AF) for a variety of grid resolutions using a single TFM image of a specified flaw. Thus, the grid resolution may be set so that it yields a desired AF using a calculation process without performing a blind iterative process. Moreover, examples of the present subject matter may measure AF in more than one axis, improving accuracy.Type: GrantFiled: October 9, 2020Date of Patent: November 8, 2022Assignee: Evident Canada, Inc.Inventors: Nicolas Badeau, Guillaume Painchaud-April

Publication number: 20220341885Abstract: Using various techniques, a position of a probe assembly of a non-destructive inspection system, such as a phase array ultrasonic testing (PAUT) system, can be determined using the acoustic capability of the probe assembly and an inertial measurement unit (IMU) sensor, e.g., including a gyroscope and an accelerometer, without relying on a complex encoding mechanism. The IMU sensor can provide an estimate of a current location of the probe assembly, which can be confirmed by the probe assembly, using an acoustic signal. In this manner, the data acquired from the IMU sensor and the probe assembly can be used in a complementary manner.Type: ApplicationFiled: February 7, 2022Publication date: October 27, 2022Inventors: Nicolas Badeau, Benoit Lepage

A processor can use the reconstructed acoustic data, such as an FMC matrix, to recreate new encoded acoustic images, such as TFM image(s), using different generation parameters (e.g., acoustic velocity, part thickness, acoustic mode, etc.Type: ApplicationFiled: September 13, 2021Publication date: May 26, 2022Inventors: Nicolas Badeau, Guy Prefontaine, Benoit Lepage
