Abstract: A bearing provides an outer ring and an inner ring capable of rotating concentrically relative to one another, at least one of the inner and outer rings being split into a plurality of successive circumferential ring segments. For each pair of facing ends of adjacent successive ring segments of the split-ring, one of the facing ends includes at least one protrusion made in one part with the associated ring segment and protruding into a recess of complementary shape formed onto the other facing end to align the pair of facing ends in radial direction.

Abstract: A patch configured to fix an electronic system, which includes a sensor, to a tire. The patch has a foot with a surface configured to be fixed to the tire. The foot has at least two portions connected to one another by at least one bridging element. The bridging element has, in a section which is parallel to the surface of the foot that is configured to be fixed to the tire, a surface area which is smaller than the overall surface area in the same section between the connected portions of the foot. In the same section, the bridging element continuously connects the connected portions of the foot.

Abstract: A method of timing a remarkable angular position (?R) of at least one sensor (12) carried by a tire (10) rotating relative to an external frame of reference. The following steps are performed: forming, from an output signal from the sensor (12), a reference signal suitable for presenting a remarkable extremum during one revolution of the tire (10); determining the time of an origin angular position (?0) of the sensor as being the time of the remarkable extremum of the reference signal; and determining the time of the remarkable angular position (?R) relative to the time of the origin angular position.

Abstract: Disclosed is a methodology for deriving data related to various selected tire (10) conditions. One or more sensors are analyzed in a manner similar to that of analyzing an electro-cardiogram taken from a human patient in order to determine selected operational characteristics of the monitored tires (10). Analysis of the signal waveforms may involve analysis of a single waveform and/or comparison of paired waveforms originating for sensors associated with a single tire or paired tires (10).

Abstract: A method of quantifying the utilization of a maximum grip potential of a tire running on the ground. At two distinct azimuth angles, at least two respective values are determined for a differential extension of the tread of the tire or for a shear of the tread that is homogeneous with said differential extension. The utilization is quantified with the help of a function of the two determined values.

Abstract: A tire provided with a Seebeck effect thermoelectric generator to deliver electrical power to a member, the generator comprising a cold pole and a hot pole respectively in contact with a cold element and a hot element, the hot element forming a portion of the tire.

Abstract: A method of determining a maximum adhesion coefficient of a tire while running on ground, the method comprising the following steps: determining the maximum adhesion coefficient as being an output from a main transfer function that is independent of at least one slowly-varying parameter; and determining at least one input of the main transfer function as being an output from a transfer pre-function that depends on said slowly-varying parameter.

Abstract: According to the method, the risk is estimated as a function of a maximum grip potential ?max of the tire, a utilization percentage Pu representative of the fraction of the maximum grip potential of the tire that is being used, and a magnitude Ps associated with a risk of the tire hydroplaning, in particular a loss of tire area.

Abstract: A method of determining a friction coefficient ? in a contact area of a tire on a road. Fixed points are selected that lie at different azimuths along a circumference of at least one bead of the tire. A shear stress value is measured at each of the fixed points while the tire is rolling on the road. The measured shear stress values are processed to determine the friction coefficient ?.
