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.

In accordance with presently disclosed embodiments, a tire monitoring system is provided. The tire monitoring system utilizes a heat sensor embedded in a solid rubber tire. The heat sensor detects a temperature of the solid tire, and a transmission system transmits signals indicative of the temperature from the heat sensor to a remote monitoring system. The remote monitoring system may monitor the temperature of the solid tire and output notifications to alert a user when preventive maintenance is needed. The heat sensor may be embedded in the solid rubber tire during the manufacture of the solid tire, or the heat sensor may be embedded into the solid tire after production of the tire is complete. The system may be used track cure time and temperature as the tire is being produced and/or to log tire performance information throughout the operation of the tire.

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.

A flexible sensor for monitoring operating parameters, including pressure and temperature, of a flexible structure, such as a tire, provides electrodes and an active area that are formed of flexible materials. In particular, the active area may be formed from an elastomeric piezoresistive material, such as an ionic liquid-polymer. The flexible properties of the sensor allow it to be readily incorporated into the body of a tire during manufacture. This allows the operating parameters of the tire to be monitored, such as in real-time, while the tire is in operation. Furthermore, the sensor is formed of materials that allow the sensor to be formed using additive manufacturing techniques, such as 3D (three-dimensional) printing. As such, the sensor may be 3D printed together with another structure, such as a tire tread, so that the sensor is integrated therein.

An apparatus (14) for installation and removal of electronic components (10) for a tire comprises an expansion device (16) having a plurality of movably supported longitudinal prongs (18), wherein the expansion device (16) is adapted for moving at least a part of the plurality of prongs (18) between a neutral position with a least distance between the prongs (18) and at least one expansion position with a distance between the prongs (18) exceeding the least distance. The prongs (18) comprise prong tips (20), which each comprise a curved engagement surface (22), wherein each prong is adapted for engaging an exposed top lip (8) of an elastic container (2), in which the electronic component (10) is storable. The expansion device (16) is adapted for moving at least a part of the plurality of prongs (18) to an expansion position with the engagement surfaces (22) engaging the top lip (8) of the container (2), in which expansion position the top lip (8) is expanded.

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).

Tyre, in particular cycle tyre, with a device for generating rotation-dependent signals, in which the device is arranged in the tyre (1, 3) or is connected to the tyre and has a signal-generating element (6, 14), which is held in a retaining element connected positively or non-positively to the tyre body, wherein the receiving element is arranged substantially on the outside of strengthening elements or reinforcing elements of the tyre and the signal-generating element is held in the retaining element in such a way that the signal-generating element forms part of the outer surface of the tyre or protrudes beyond the outer surface of the tyre.

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.
