  • Publication number: 20100059159
    Abstract: A tire designed to be mounted and pressurized on a vehicle wheel rim that has at least one circumferential seat for a bead belonging to the tire and an outward radial projection in the vicinity of the seat. A circumferential crown is provided with a tread for ensuring contact with the ground. At least one bead has a portion suitable for being mounted on the rim seat. A wall comprising a structure of rubber and reinforcements connects the crown to the bead. The whole formed by these elements defines with the rim an air chamber. At least one protective element is located in a sector where the tire wall between the crown and the bead could become pinched between the projection and an obstacle external to the tire in response to a violent impact due to the tread meeting this obstacle, causing closure of the internal cavity of the tire in this sector and momentary high compressive stresses perpendicular to the wall of the tire.

  • Patent number: 7674117
    Abstract: A strain-resistant electrical connection and a method of making the same is provided. A wire or other conductive lead is connected to a circuit in a manner that makes the connection more resistant to mechanical stresses such as movement or rotation of the lead relative to the circuit. A material is configured around the lead and near the point of connection to the circuit so as to create a region of decreasing flexibility or graduated stiffness near the point of connection. In certain embodiments, the lead may also be coiled or otherwise shaped to provide additional ability to withstand mechanical stresses.

  • Patent number: 7660679
    Abstract: A method for evaluating the difference between the situation on a site at a given moment and a reference state in regards to the operating conditions of tires of heavy vehicles of the civil engineering type, wherein a user determines at least one zone on the site and determines n parameters which are characteristic of the operating conditions for tires in the zone. The user allocates to each parameter a variance dimension (xi) and enters this dimension in a processor capable of performing an automatic consolidation I of the dimensions of the n parameters. The processor performs a consolidation of the dimensions of the n parameters to give I, the variance dimension index for the zone.
