A flexible sensor unit is embedded in a tire. The flexible sensor unit includes a plurality of individual circuit boards. Each circuit board includes at least one electronic component. The at least one electronic component includes a radio frequency identification integrated circuit, a microcontroller unit, at least one sensor, a power source and a boost converter. Each one of a plurality of electrically conductive flexible connecting ribbons extends between the circuit boards. An end ribbon is electrically connected to at least one of the circuit boards. An antenna is disposed on the end ribbon. The antenna transmits data from the at least one sensor, as processed by the microcontroller unit, and identification data from the radio frequency identification integrated circuit, to an external reader.

Pneumatic tyre having a toroidal carcass, which has a body ply that is partially folded onto itself and therefore having two lateral flaps; two annular beads, each of which is surrounded by the body ply and has a bead core and a bead filler; an annular tread; a pair of sidewalls; a pair of abrasion gum strips; an innerliner which is impermeable to air and is arranged within the body ply; and a transponder which is arranged between the body ply and the innerliner at a flap of the body ply and is arranged at a distance of less than 7 mm from an edge of the body ply.

In accordance with embodiments of the present disclosure, systems and methods for taking acoustic/ultrasonic wave measurements of a wellbore using a downhole tool equipped with microelectromechanical (MEM) transducers are provided. The MEM transducers may include a plurality of MEM transmitters (e.g., MEM speakers) and a plurality of separate MEM receivers (e.g., MEM microphones). These MEM transducers may be disposed in arrays proximate an outer surface of the downhole tool to collect acoustic/ultrasonic wave measurements of the full circumference of a wellbore. Due to their small size, large numbers of MEM transducers may be distributed radially around the downhole tool. Such an arrangement of sensors may enable the downhole tool to perform measurements of the entire wellbore without the downhole tool needing to be rotated, leading to an increased signal-to-noise ratio of the measurements.

Identification labels and their incorporation in rubber-based articles are described. The labels include RFID components and can be incorporated in tires. The labels can withstand the relatively harsh conditions associated with vulcanization.

The RF tag known in the art incorporated in a tire has a problem that it can easily get distorted when the stresses occurring in the running tire converge on its vicinity. The present invention provides a tire (1) configured to prevent distortion from occurring in the RF tag (50) incorporated therein. The tire (1) includes an RF tag structure (50A) which is constructed of the RF tag (50) covered with a coating rubber (51). The modulus of elasticity of the coating rubber (51) is higher than that of the rubbers of the adjacent members (13, 32) located adjacently on the respective axial sides of the coating rubber (51).

Disclosed herein are automated systems and methods utilizing a plurality of specialized RFID tags incorporated within various tire manufacturing components (e.g., mold segments, mold container, bladder plates, tire presses, and extrusion dies) that are able to readily track tire manufacture and identify defect source(s) while concurrently being configured to the harsh processes and temperatures of tire manufacture.

A tire includes a central region configured to be mounted to a wheel and a crown region including a circumferential tread and a shear element disposed below the circumferential tread. The shear element includes an upper reinforcement layer, a lower reinforcement layer, and an elastic region disposed between the upper reinforcement layer and the lower reinforcement layer. A radial distance between the upper reinforcement layer and the lower reinforcement layer varies along an axial width of the tire. The tire also includes an intermediate region extending from the central region to the crown region.

The invention relates to a method for producing a rubber component (1), in the case of which at least one electronic assembly (2) is embedded between a lower and an upper ply (10, 11) of a rubber material, comprising the steps: a) providing a length portion of the lower ply (10) of the rubber material, which is equipped, on the top side (100), with at least one electronic assembly (2); b) stationarily positioning the length portion of the lower ply (10); c) unrolling a length portion of the upper ply (11) of the rubber material on the top side (100) of the stationary length portion of the lower ply (10) in an unrolling direction (A), and fixedly adhesively connecting the length portions of the plies (10, 11) of the rubber material so as to embed the at least one electronic assembly (2); d) conveying out the length portion of the rubber component (1).

A corresponding device for producing the rubber components (1) is also specified.

A tire includes an electronic device, such as a RFID chip, within the body of the tire. For particular embodiments, a RFID chip is disposed within a tire belt. The RFID chip may be disposed on an inner or outer belt. The RFID chip is connected to at least one steel cords forming an antenna for the RFID chip. The steel cords are disposed at a first angle and second angle with respect to the tire equator. A method of joining the RFID chip to a tire cord is also provided.

A pneumatic tire includes, on a tire inner surface, at least one housing body made of rubber and configured to accommodate a sensor unit including a sensor for acquiring tire information. The housing body includes an opening portion through which the sensor unit is inserted, and is vulcanization-bonded to the tire inner surface.
