Publication number: 20110148401Abstract: A self-contained device intended to be carried by a wheel-tire assembly in order to locate whether the assembly is positioned on the right side or on the left side of a vehicle is described. The device includes two magnetic sensors with axes of maximum sensitivity, the sensors providing two periodic signals that are phase shifted relative to one another. Each signal is representative of variations in the magnitude of the magnetic field detected by the sensor during a revolution of the wheel-tire assembly. The device also includes a processing unit programmed to determine, from the phase shift between the two periodic signals, a direction in which the wheel-tire assembly is rotating and to deduce, from this direction of rotation and from a direction of travel of the vehicle, whether the wheel-tire assembly is located on the right side or on the left side. The two magnetic sensors are intended to be positioned on the wheel-tire assembly at distinct azimuthal locations.Type: ApplicationFiled: July 21, 2009Publication date: June 23, 2011Applicants: SOCIETE DE TECHNOLOGIE MICHELIN, MICHELIN RECHERCHE ET TECHNIQUE S.A., TRW AUTOMOTIVE US, LLCInventors: Thierry Penot, Franck Daumas, Xavier Huchard, Christophe Villien

Publication number: 20110062631Abstract: A method to cure a non-uniform rubber article uses one or more high thermal diffusivity pins in a mold to direct heat to the cure-limiting parts of the article to reduce the total cure time in the mold and increase the uniformity of the cure of the article. Reductions in cure time of up to 20% or more are achieved without substantially changing the function or degrading the performance of the article. The method is particularly useful for curing tires and treads for tires. Finite element analysis or thermocouple probes can used to determine the cure-limiting part(s) for the tire or tread. Using this knowledge, one or more of the high thermal diffusivity pins are located in the mold at positions to transfer heat into the cure-limiting part(s).Type: ApplicationFiled: May 22, 2008Publication date: March 17, 2011Applicants: MICHELIN RECHERCHE ET TECHNIQUE S.A., SOCIETE DE TECHNOLOGIE MICHELINInventor: Christopher S.
