A process for manufacturing a rubber patch comprising a radiofrequency transponder, the patch having a first layer and a second layer, the method comprising moulding and vulcanizing a first layer, the exterior surface of which comprises a cavity able to receive a radiofrequency transponder, placing a transponder in the cavity, and then placing and vulcanizing a second layer in order to embed the transponder between the two layers.

Method for manufacturing a patch equipped with a radiofrequency transponder

A tire comprises an interior surface and an exterior surface, an accommodating region arranged on one of said interior and exterior surfaces, an adhesive layer arranged on the accommodating region and a member attached to the accommodating region by the adhesive layer, in which the adhesive layer is based on a silanized polyether.

Tire with an element attached to the surface thereof and method for attaching an element to the surface of a tire

A tire casing is equipped with a radiofrequency transponder and includes a crown, two sidewalls and two beads revolving around a reference axis, first threads forming outward segments and return segments that are arranged adjacently, aligned circumferentially, anchored in the two beads with, in each bead, loops in each case linking an outward segment to a return segment and, in each bead, means for anchoring the first threads, comprising second threads oriented circumferentially axially bordering the first threads and forming at least one spiral, the first threads forming at least one circumferential alignment defining the carcass ply that separates said tire casing into two zones, inside and outside with respect to this carcass ply. The radiofrequency transponder comprises at least one electronic chip and a radiating radiocommunication antenna and is positioned radially externally in relation to the at least one spiral, characterized in that the radiofrequency transponder comprises a primary antenna electrically connected to the electronic chip, in that the primary antenna is electromagnetically coupled to the radiating antenna, and in that the radiating antenna is formed by a single-strand helical spring defining a first longitudinal axis.

Pneumatic tire equipped with an electronic member

A tire casing is equipped with a radiofrequency transponder and includes a crown, two sidewalls and two beads, each bead including at least one annular bead wire revolving around a reference axis, at least one annular carcass ply, coaxial with the reference axis anchored in the beads separating the tire casing into two zones, inside and outside the carcass ply. The radiofrequency transponder comprises at least one electronic chip and a radiating radiocommunication antenna and is positioned radially externally in relation to said bead wire, characterized in that the radiofrequency transponder comprises a primary antenna electrically connected to the electronic chip, in that the primary antenna is electromagnetically coupled to the radiating antenna, and in that the radiating antenna is formed by a strand helical spring defining a first longitudinal axis.
