Patent number: 11181591Abstract: A sensor device is provided for use in tire inspection. The sensor device is configured for removable placement along the inner surface of the tire. The sensor device includes multiple rows of sensors, which are used to provide signals that can compensate for the effect of vibrations or mechanical agitation as the sensors are passed over the inner surface of the tire. The sensor device may have a profile that allows for placement of the multiple rows of sensors in close proximity to the inner surface of the tire.Type: GrantFiled: May 7, 2020Date of Patent: November 23, 2021Assignee: MICHELIN RECHERCHE ET TECHNIQUE S.A.Inventors: Bradley D. Schober, Frank E. Gramlin, David A. Judd

Patent number: 11175262Abstract: The present disclosure describes methods of inspecting polymeric material that includes one or more elongated ferrous reinforcements. The method includes applying a magnetic field to any one or more reinforcements. The method further includes positioning an array of magnetic flux sensors near the one or more reinforcements, and detecting the presence of magnetic flux leakage along any of the one or more reinforcements. It is then determined whether the magnetic flux leakage occurs at a damaged location along the one or more reinforcements or at a reinforcement joint.Type: GrantFiled: June 30, 2017Date of Patent: November 16, 2021Assignee: Compagnie Generale des Etablissements MichelinInventors: Frank E.

Patent number: 10533929Abstract: A method of using a sensor device for tire inspection is provided. Signals are received from multiples rows of sensors separated by a predetermined distance. The sensors are positioned next to the inner surface of the tire for inspection. Signals from the different rows of sensors are used to identify e.g., breaks in the reinforcements of the tire and also used to identify undesirable signals generated from vibration or jarring of the sensor device.Type: GrantFiled: January 5, 2016Date of Patent: January 14, 2020Assignee: Compagnie Generale des Etablissements MichelinInventors: Bradley D.

Patent number: 10006835Abstract: A sensor device is provided for use in tire inspection along a bead portion of the tire. The sensor device includes a magnet array configured to provide the desired fields of magnet flux for a sensor array, which is used to detect damage to reinforcements of a body ply of the tire near the bead portion. The fields of magnetic flux are sufficient to provide for damage detection in the bead portion without overly saturating the sensor array. The sensor device also allows for positioning the sensor array proximate to the inner surface of the tire for improved detection.Type: GrantFiled: March 13, 2014Date of Patent: June 26, 2018Assignee: COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELINInventors: Bradley D.

Publication number: 20110183375Abstract: The present invention is directed generally to metal binding compounds which may be added to cell culture media to replace factors required for cultivation of the cells (e.g. transferrin) which are of animal or human origin. More specifically, the invention is directed to metal binding compounds or complexes thereof comprising one or more transition element cations (such as ferrous or ferric ions), which are added to cell and tissue culture medium compositions. The metal binding compounds may be added to the media alone or may be first complexed with a transition metal ion. The invention is also directed to methods of use of such compositions, including, for example, methods for the cultivation of eukaryotic cells, particularly animal cells, in vitro. The invention also relates to compositions comprising such culture media and one or more cells, and to kits comprising one or more of the above-described compositions.Type: ApplicationFiled: January 25, 2011Publication date: July 28, 2011Applicant: LIFE TECHNOLOGIES CORPORATIONInventors: David A.
