Patent number: 11921487Abstract: A system and method for manufacturing a component is provided that includes a CNC machine tool, a correction module, and a system controller. The CMM module is controllable to determine a set of multi-axis coordinates surface points on the component. The correction module is in communication with the CMM module and stored reference inspection data. The system controller is in communication with the CNC machine tool, the correction module, and stored instructions. The instructions when executed cause the system controller to: a) control the CNC machine tool to modify a surface of the component; b) control the CMM module to determine multi-axis coordinates for surface points; c) determine surface position variances using the reference inspection data and the multi-axis coordinates; d) determine if surface position variances exceed a threshold; and e) create correction action instructions for controlling the CNC machine if surface position variances exceed the threshold.Type: GrantFiled: February 18, 2022Date of Patent: March 5, 2024Assignee: Pratt & Whitney Canada Corp.Inventors: Rachid Guiassa, Mizanur Rahman, Pierre-Alexandre Lafreniere, Martin Perron, Luc Sauve

Publication number: 20220244194Abstract: A method and system for performing inspection of a manufactured article includes acquiring a sequence of images using an image acquisition device of the article under inspection. The sequence of images is acquired while relative movement between the article and the image acquisition device is caused. At least one feature characterizing the manufactured article is extracted from the acquired sequence of images. The acquired sequence of images is classified based in part on the extracted feature. The classification may include determining an indication, of a presence of a manufacturing defect in the article, and may include identifying a type of manufacturing defect. The extracting and the classifying can be performed by a computer-implemented classification module, which may be trained by machine learning techniques.Type: ApplicationFiled: June 4, 2020Publication date: August 4, 2022Applicant: Lynx Inspection Inc.Inventors: Luc Perron, Roger Booto Tokime

Patent number: 10825165Abstract: A method for performing inspection of a manufactured article. The method comprises acquiring a sequence of radiographic images of the article; determining a position of the article for each one of the acquired radiographic images; and performing a three-dimensional model correction loop which comprises, iteratively: generating a simulated radiographic image for each determined position of the article; and comparing the simulated radiographic images and the acquired radiographic images and generating a match result. If the match result is indicative of a mismatch, the method includes identifying and characterizing differences between the simulated radiographic images and the acquired radiographic images; correcting one of a geometry and a material density of a region of interest of the detailed three-dimensional model of the article based on each one of the identified and characterized differences; and performing a new iteration. A system for performing inspection is also provided.Type: GrantFiled: July 21, 2017Date of Patent: November 3, 2020Inventors: Luc Perron, Dominique Boutet, Steve Godbout

Patent number: 10275660Abstract: A method and apparatus for screening luggage are provided. X-ray images derived by scanning the luggage with X-rays are received and processed with an automated threat detection (ATD) engine. A determination is then made whether to subject respective ones of the X-ray images to further visual inspection by a human operator at least in part based on results obtained by the ATD engine. In certain cases, visual inspection by a human operator is by-passed and the ATD results are relied upon in order to mark luggage for further inspection or to mark luggage as clear. In another aspect, X-ray images derived by scanning the luggage using two or more X-ray scanning devices are pooled at a centralized location. ATD operations are applied to the X-ray images, which are then provided “on-demand” to a human operator for visual inspection. Results of the visual inspection are entered by the human operator and then conveyed to on-site screening technicians associated with respective X-ray scanning devices.Type: GrantFiled: August 8, 2017Date of Patent: April 30, 2019Assignee: VANDERLANDE APC INC.Inventor: Luc Perron

Patent number: 9194975Abstract: A method, an apparatus and a system are provided for determining if a piece of luggage contains a liquid product comprised of a container holding a body of liquid. The piece of luggage is scanned with an X-ray scanner to generate X-ray image data conveying an image of the piece of luggage and contents thereof. The X-ray image data is processed with a computer to detect a liquid product signature in the X-ray image data and determine if a liquid product is present in the piece of luggage. A detection signal is released at an output of the computer conveying whether a liquid product was identified in the piece of luggage. The detection signal may, for example, be used in rendering a visual representation of the piece of luggage on a display device to convey information to an operator as to the presence of a liquid product in the piece of luggage.Type: GrantFiled: September 25, 2014Date of Patent: November 24, 2015Assignee: OPTOSECURITY INC.Inventors: Stephane Drouin, Regis Poulin, Luc Perron, Dan Gudmundson

Patent number: 8494210Abstract: An apparatus, method and system for facilitating visual identification of a prohibited object in an image during security screening are provided. Data derived from an apparatus that scans the receptacle with penetrating radiation conveying an image of the contents of a receptacle is received. Information from an automated threat detection processor is also received and indicates an area of interest in the image potentially containing a prohibited object. The image is then processed to generate an enhanced image. In a first example, portions of the enhanced image outside the area of interest are visually de-emphasized. In a second example, features appearing inside the area of interest are visually emphasized. The enhanced image is then displayed on a display device. Optionally, thumbnail images associated with previously screened receptacles are displayed and a user is enabled to select one or more thumbnail images. An enhanced image corresponding to the selected thumbnail image is then displayed.Type: GrantFiled: March 30, 2007Date of Patent: July 23, 2013Assignee: Optosecurity Inc.Inventors: Dan Gudmundson, Luc Perron

Patent number: 7991242Abstract: A method and an apparatus suitable for screening a receptacle are provided. An image signal conveying an input image related to contents of the receptacle is received, the image signal having been produced by a device that is characterized by introducing distortion into the input image. A distortion correction process is applied to the image signal to remove at least part of the distortion from the input image, thereby to generate a corrected image signal conveying at least one corrected image. The corrected image signal is processed in combination with a plurality of data elements associated with a plurality of target objects in an attempt to detect a presence of at least one of the target objects in the receptacle. A detection signal is generated in response to detection of the presence of at least one target object in the receptacle.Type: GrantFiled: May 11, 2006Date of Patent: August 2, 2011Assignee: Optosecurity Inc.Inventors: Luc Perron, Michel R.
