A disclosed component may include at least one split-ring resonator, which may be embedded within a material. The split ring resonator may be formed from a three-dimensional (3D) monolithic carbonaceous growth and may detect an electromagnetic ping emitted from a user device. The split ring resonator may generate an electromagnetic return signal in response to the electromagnetic ping. The electromagnetic return signal may indicate a state of the material in a position proximate to a respective split ring resonator. In some aspects, the split-ring resonator may resonate at a first frequency in response to the electromagnetic ping when the material is in a first state, and may resonate at a second frequency in response to the electromagnetic ping when the material is in a second state. A resonant frequency of the 3D monolithic carbonaceous growth may be based on physical characteristics of the material.

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.

Provided is a tire structure technology with which sufficient reading performance can be maintained even when a tire having an electronic component provided therein is caused to drive under high speed and severe handling. A pneumatic tire in which an electronic component is provided farther outward in a tire axial direction than a carcass, and in which the tan δ(1).sub.50° C. and tan δ(1).sub.150° C. of a first rubber member, and the tan δ(2).sub.50° C. and tan δ(2).sub.150° C. of a second rubber member, satisfy the following formula, where the first rubber member is a tire rubber member that has the greatest E* at 50° C. among tire rubber members positioned outward from the electronic component in the tire axial direction, and the second rubber member is a tire rubber member that has the greatest E* at 50° C. among tire rubber members positioned inward from the electronic component in the tire axial direction.

Methods for increasing the read range of an electronic communication module within a tire and methods for improving the read range of an electronic communication module within a tire are provided herein. As discussed further herein, the read range can be increased by applying strain to the tire without abrading its tread, resulting in an increase in read range of 20% or more. Similarly, the read range can be improved by applying strain to the tire without circumferentially contacting the outer surface of its tread, resulting in an increase in the same-distance-signal-strength of 5% or more. Also provided are tires made according to the disclosed methods.

The present invention provides a method and system for verifying and tracking identification information. In an embodiment of the invention, a system for delivering security solutions is provided that includes at least one of the following: a radio frequency (RF) identification device, an identification mechanism (e.g., a card, sticker), and an RF reader.

A chemically treated, RFID equipped mesh tire label configured to be integrally incorporated within a vulcanized tire and to provide unique identifier(s) and/or other information about the vulcanized tire during and post tire vulcanization, the label comprising: a mesh face layer configured to be adhered to an outer surface of an unvulcanized tire; a mesh backing layer attached to the mesh face layer and adapted to be integrally incorporated in a vulcanized tire after subjecting a green tire to a vulcanization process; and an RFID device affixed between the mesh face and mesh backing layers, the RFID device that is configured to provide unique identifier(s) and/or other information upon being read with an RFID reader during and post tire vulcanization.

A rubber composition for covering an electromagnetic tag is proposed. The rubber composition may include a base rubber and a reinforcing filler comprising carbon black or boron nitride. The rubber composition may also include an insulating filler comprising at least one selected from silica, titanium dioxide, talc and calcium carbonate. The rubber composition may further include a reinforcing resin comprising an alkyl phenol formaldehyde resin or a resorcinol formaldehyde resin. Based on 100 parts by weight of the base rubber, the total amount of the reinforcing filler and the insulating filler may be 40 parts by weight or more, the amount of the insulating filler may be 10 parts by weight or more, and the amount of the reinforcing resin may be 0.5 parts by weight to 5 parts by weight.

Disclosed are pre-cure RFID-enabled bead labels based on an RFID inlay construction consisting of an aluminum antenna etched on to a high temperature resistant polyimide film that is connected to an integrated memory circuit positioned on the surface of the polyimide film. This RFID inlay being further inserted into an overall label construction having a plurality of layers that include, for example, a plurality of polyester layers and a plurality of high temperature resistant adhesive layers that bond/adhere layers together, the plurality of layers further protecting and insulating the RFID inlay while the label is bonded to the external bead (or sidewall) of a tire. The compositions/devices disclosed herein can be used for electronic identification when applied on rubber-based articles (e.g., tires) prior to being subjected to stress related to the vulcanization process and normal use of this article during the manufacturing process.
