Patent number: 11981166Abstract: A tire fitted with a transponder comprises: a crown comprising a crown reinforcement having an axial end at each of its edges, connected at each of its axial ends by a sidewall to a bead having an interior end; a carcass reinforcement layer formed of parallel reinforcers, which is anchored in each bead around a bead wire to form a main part and a turn-up; and the transponder comprising a dipole antenna consisting of a spring defined by a pitch P and a diameter D. A ratio between the pitch (P1) and the diameter (D1) for a loop of a first region of the spring is greater than 0.8, and the transponder is situated axially on the outside of an interior end of the bead and radially between the upper end of the bead wire and the axial end of the crown reinforcement.Type: GrantFiled: September 22, 2020Date of Patent: May 14, 2024Assignee: COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELINInventors: Julien Destraves, Laurent Couturier, Pierre Guinault, Emmanuel Joulin, Sebastien Fredon

Patent number: 10099400Abstract: A method and system for detecting and controlling the quality of debarking at the surface of a wooden log provide information on main parameters related to the debarking quality of the log surface, including fiber loss and residual bark. The debarking quality detecting method and system involve measurement of three-dimensional profile of at least a portion of the log surface to generate corresponding profile image data, which is processed to generate data indicative of the texture of the log surface. The texture data is then analyzed to generate resulting data on the debarking quality parameters. That quality indicative information can be generated on a continuous basis to provide an objective assessment of the quality performance in real-time in view of target productivity, and may then be used to perform optimal adjustments of the debarker operating parameters, either manually by the operator or automatically through feedback control.Type: GrantFiled: September 13, 2012Date of Patent: October 16, 2018Assignee: CENTRE DE RECHERCHE INDUSTRIELLE DU QUÉBECInventors: Richard Gagnon, Jean-Pierre Couturier, Philippe Gagné, Feng Ding, Fadi Ibrahim

Patent number: 9638642Abstract: An apparatus and a method for optically scanning a surface of an object under an adverse external condition to which optical components are subjected, such as cameras and lighting sources sensitive to soiling, make use of a first imaging sensor unit having its optical components subjected to the adverse external condition, and being configured for generating reflection intensity image data associated with a target surface. A second imaging sensor unit having its optical components substantially not subjected to the adverse external condition, is configured for generating reflection intensity image data associated with a reference surface. Correction data are calculated from a comparison between the reflected intensity image data associated with the target and reference surfaces, which correction data are then applied to the reflected intensity image data associated with the target surface to generate corrected intensity image data compensating for the adverse external condition.Type: GrantFiled: November 28, 2014Date of Patent: May 2, 2017Assignee: CENTRE DE RECHERCE INDUSTRIELLE DU QUEBECInventor: Jean-Pierre Couturier

Patent number: 9262809Abstract: Methods and apparatus for filtering noise of low frequency from an image of the surface characteristics of an object expressed with reference to orthogonal first and second axis and obtained with linear light scanning, involve calculating a difference between pixel values of an image column vector along the second axis adjacent a selected reference image column vector and respective pixel values of the selected reference image column vector to obtain a pixel difference vector. The pixel difference values not mainly associated with a corresponding atypical change of surface characteristics as compared with noise are then selected, and a mean value from the selected pixel difference values are calculated as an estimated value of the noise. The estimated noise value are subtracted from the adjacent image column vector to obtain a corrected image column vector.Type: GrantFiled: April 4, 2014Date of Patent: February 16, 2016Assignee: CENTRE DE RECHERCHE INDUSTRIELLE DU QUEBECInventors: Richard Gagnon, Jean-Pierre Couturier

Publication number: 20140218504Abstract: An apparatus and a method for scanning a surface of an article such as a wooden piece transported along a travel path axis, are capable of generating two complementary color image frames representing the surface of the article in an efficient way. While the sensing field of an imaging sensor is directed transversely toward the travel path axis, a first linear-shaped light beam characterized by a first wavelength is directed toward the scanning zone to form a first reflected line onto the article surface. A second linear-shaped light beam characterized by a second wavelength is directed toward the scanning zone to form a second reflected line onto the article surface.Type: ApplicationFiled: January 31, 2014Publication date: August 7, 2014Applicant: CENTRE DE RECHERCHE INDUSTRIELLE DU QUEBECInventors: Jean-Pierre COUTURIER, Richard GAGNON, Gregory DORVAL

Patent number: 6175092Abstract: A method and apparatus for classifying batches of wood chips or the like according to light reflection characteristics; provide optimal use of darker wood chips in pulp and paper processes. According to a preferred embodiment, light produced by a set of illumination sources is evenly directed onto superficial wood chips of an inspected batch portion transported on a conveyor while being inspected by a camera disposed over the conveyor. The superficial wood chips presenting light reflection characteristics being substantially representative of the wood chips of the inspected batch, reflected light is sensed by the camera to produce electrical signals representing rejection intensity values for the wood chips of the batch portion.Type: GrantFiled: September 30, 1998Date of Patent: January 16, 2001Assignee: Centre de Recherche Industrielle du Qu{acute over (e)}becInventors: Sylvain Binette, Jacques Labb{acute over (e)}, Pierre B{acute over (e)}dard, Jean-Pierre Couturier
