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 patch is provided for an electronic device of a tire. The patch includes first and second compartments. The first compartment, which does not include an opening, is structured to house therein an electronic identification module. The second compartment, which includes a reclosable opening, is structured to house therein an electronic module having a complementary function to a function of the electronic identification module. The electronic module is adapted to receive identification data from the electronic identification module.

A tire and securing element assembly includes a tire inflated at a first pressure and a securing element. The securing element is an inflatable hoop inflated at a second pressure at least 10% greater than the first pressure. The securing element abuts an inner surface of the tire across 30-90% of a tread width. The securing element has a cross sectional area between about 0.4 and 47.0 cm.sup.2.

An RFID mesh label configured to be integrally incorporated within a vulcanized tire and to further provide unique identifier(s) and/or other information about the vulcanized tire during and/or post-vulcanization, the RFID mesh label including a face layer configured to be positioned adjacent or flush to an outer surface of the vulcanized tire; an RFID layer positioned underneath the face layer, the RFID layer having an RFID device that is configured to provide unique identifier(s) and/or other information about the vulcanized tire upon being read with an RFID reader; and a mesh backing overlying the RFID layer and adapted to be integrally incorporated in a vulcanized tire after subjecting a green tire to a vulcanization process.

A method for installing a sensor onto an inner surface of a tire is generally disclosed. The method includes robotically deglazing at least a portion of the inner surface of the tire, defining a preconditioned surface. The sensor is robotically selected and a target surface of the sensor is cleaned. An adhesive is applied to at least a portion of the target surface of the sensor. In some embodiments, the adhesive is applied to a portion of the preconditioned surface. The sensor is robotically positioned, wherein the target surface of the sensor abuts the preconditioned surface. A wet-out operation is performed, wherein a predetermined pressure is applied to the sensor for a predetermined period of time to affix the sensor to the preconditioned surface.

A foam based RFID label and a method of installing the same. The method includes of forming a recess having a predetermined shape on an outermost or innermost surface of the tire; providing the foam-based RFID label configured to identify the tire and/or to sense conditions of the tire and communicate the same to an RFID reader; and affixing the foam-based RFID label within the recess of the tire by contacting and adhering an adhesive surface of the foam-based RFID label to a surface of the recess to identify the tire and/or sense conditions of the tire.

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.

RFID plugs and methods of installing the same within a rubber article. When included in the rubber article, the RFID plugs maintain operability pre-vulcanization, during vulcanization, and post-vulcanization to identify, track, and/or sense conditions of the rubber article. The RFID plugs are adapted to be affixed to the rubber article and include, for example, an elongate stem; a head disposed at a first end of the stem, the head containing an RFID device; and a retention feature disposed at a second end of the stem opposite the first end, the retention feature configured to resist pulling forces on the head and the stem.

An implantable electronic tag (100) for a tire and an assembly process. The electronic tag (100) mainly comprises: an antenna (102); a radio frequency chip module (101); and a connection terminal (103). The radio frequency chip module (101) has an electrode (101b) provided thereon. The connection terminal (103) has one end connected to the antenna (102) and another end in cold-press connection with the electrode (101b) of the radio frequency chip module (101). Upon assembly, a radio frequency chip is encapsulated to form the radio frequency chip module (101). The connection terminal (103) is initially riveted to the antenna (102) and then connected to the electrode (101b) of the encapsulated body by means of cold-pressing. The radio frequency chip module (101) connected to the antenna (102) is encapsulated. The implantable electronic tag (100) for a tire is an ultra-high frequency, readable and writable radio frequency tag. The electronic tag is compliant with HG/T 4953-4956-2016 standards for tire radio frequency identification (RFID) tag mechanical implantation methods, performance test methods and coding.

A radiofrequency transponder includes a radiating antenna and an electronic device. The radiating antenna is a single-strand helical spring forming a dipole antenna. The electronic device includes an electronic chip and a primary antenna, which are encapsulated at least partially in a rigid, electrically insulating mass. The primary antenna is electromagnetically coupled to the radiating antenna.
