Abstract: A vehicle wheel arch having an electrical circuit for communicating with an electronic component installed in a tire of the vehicle. The wheel arch comprising an electrical circuit embedded within or installed on a surface of the wheel arch. The electrical circuit includes an antenna formed by a substantially flat arrangement of an electrical conductor and configured to communicate at least one of power and data to the electronic component installed in the tire.
Abstract: A tire includes, among the conventional tread pattern elements, at least one measuring element having a central zone and an encircling zone. In normal operation, the central zone 10 of a measuring element slides over the ground while, conversely, the tread as a whole does not slide over the ground. Measurements are carried out of the maximum adherence potential with the ground, at any moment, due to the central zone of a measuring element. In an alternative embodiment, the measuring element may comprise a circumferentially extending rib(s) or tread block(s) whose ground contact surface(s) is spaced at a lesser radial distance from the wheel axle than the spacing of the ground contact surfaces of the conventional tread blocks.

Abstract: The wheel and tire assembly for running on ground includes measurement means carried by the wheel for measuring topological parameters of the inside surface of a pertinent portion of the tire. These measurement means comprise lighting and viewing means for lighting and viewing a calibrated surface pattern that is subjected to the deformation of the inside surface of the pertinent portion of the tire. The viewing means are preferably of the stereovision type or of the structured light type.
Abstract: Method for determining the load condition of a vehicle (60) moving at non-zero speed, the vehicle being equipped with a plurality of tire-wheel assemblies (41-42, 51-52) mounted on at least two axles and with devices that enable determination of the vehicle's speed and the rotation frequencies or speeds and actual inflation pressures of at least two tire-wheel assemblies mounted on two different axles of the vehicle, the method comprising the following stages: (A) determination of the inflation pressures and rotation frequencies of two tire-wheel assemblies mounted on two different axles; (B) calculation of the load difference between the two tire-wheel assemblies from the vehicle's speed and the rotation frequencies of the two tire-wheel assemblies, taking into account the actual inflation pressures; (C) determination of the load condition by comparing the calculated load difference with at least one predetermined threshold.

Abstract: Disclosed is an apparatus and methodology for insuring measurement accuracy and performance reliability in the operation of devices employed to interrogate SAW devices. The present subject matter relates to an arrangement and methodology that provides an interrogator paired together with a separate receiver, which may comprise a second interrogator, functioning together to perform a self-testing operation. The interrogator may be a handheld device that is temporarily paired with a separate receiver or a like device or the interrogator may correspond to more or less permanently paired set of devices physically placed in an array.
Abstract: Apparatus designed for laying a strip on a rotating receiving surface S, comprising a laying head (100) moving along axes XX? parallel to the axis of rotation of the surface (S) and YY? parallel to a radial direction passing through the point of contact Q between the strip application means (112) and the receiving surface (S), and capable of moving in rotation about an axis AA? substantially perpendicular to the above axes and passing through the point Q. The laying head comprises a device allowing estimation of the value of the angle ? formed by the tangent TT? to the transverse profile of the surface S and the axis XX?. The movements of the laying head are determined by the value of the angle ? in such a way as to displace the latter in a direction parallel to TT? following the transverse profile of the receiving surface.

Abstract: A method of fitting a tire P and a removable tread support S on a one-piece wheel rim J, rim comprising a first rim seat, inclined outwards, and the tire P comprises a first bead and a second bead to be mounted respectively on the first and second rim seats, in which, before completion of fitting the support S on a rim bearing surface of the rim, the first bead is gripped at a given point and is moved radially outwards to radially separate this point on the first bead from the support S. The fitting of the support S on the rim bearing surface continues and the bead is released after completion of the fitting of the support S.
Abstract: A process of depositing at least one uncured colored rubber mix forming a contrasting motif on an outer surface of a tire includes preparing a blank of the uncured tire to be moulded, including all the constituents except for the colored rubber mix(es), depositing the colored rubber(s) in at least one cavity formed on a removable insert, each cavity having the general form of the motif to be moulded and having a total volume V2, the total volume of non-vulcanized colored rubber V1 placed in each cavity being less than the volume V0, mounting the insert in a suitable housing provided on the moulding surface of the mould for the tire, engaging the tire blank within the mould, and moulding and vulcanizing the tire.
