    FIELD OF THE INVENTION
    [001] The present description refers to the field of incorporation of an electronic device in a tire. More specifically, the present description refers to the field of embedding a radio frequency identification (RFID) tag on a tire. BACKGROUND
    [002] The incorporation of an electronic device, such as a radio frequency identification tag (RFID), in a tire can occur during the construction of the tire and before vulcanization or in a post-curing procedure. Such electronic devices are useful when transmitting data, such as specific identification data, to an external reader. Ultra-high frequency ("UHF") tags are typically small and use flexible antennas for data transmission. When embedded in a tire, such as during tire construction, the electronic device represents a foreign object that can affect the structural integrity of the tire. Many locations within a tire are not suitable for placing an RFID tag because of the cyclical bending inclination in service or because the location does not allow radio frequency compatibility suitable for reading applications.

    [0012] The following are the definitions of selected terms used in this document. The definitions include several examples or forms of components that are within the scope of a term and that can be used for implementation. The examples are not intended to be limiting. Both the plural and singular forms of the terms can be within the definitions.
    [0013] "Axial" or "axially" refers to a direction that is parallel to the axis of rotation of a tire.
    [0014] "Bead" refers to the part of the tire that comes into contact with the wheel and defines a border with the sidewall
    [0015] "Circumferential" and "circumferentially" refer to a direction that extends along the perimeter of the tread surface perpendicular to the direction of the axis.
    [0016] "Equatorial plane" refers to the plane that is perpendicular to the axis of rotation of the tire and passes through the center of the tire's tread.
    [0017] "Radial" or "radially" refers to a direction perpendicular to a tire's axis of rotation.
    [0018] "Sidewall" refers to that portion of the tire between the tread and the bead.
    [0019] "Tread" refers to the portion of the tire that comes into contact with the road under normal inflation and loading.
    [0020] The directions are established in this document with reference to the geometric axis of rotation of the tire. The terms "up" and "upward" refer to a general direction towards the tire's tread, while "down" and "downward" refer to the general direction towards the tire's axis of rotation. Thus, when terms related to direction such as "top" and "bottom" or "top" and "bottom" are used with respect to an element, the "top" or "top" element occupies a space closer to the band than the "bottom" or "bottom" element. Additionally, when relative directional terms like "above" or "below" are used with respect to an element, an element that is "above" another element is closer to the tread than another element.
    [0021] The terms "inward" and "internally" refer to a general direction towards the equatorial plane of the tire, while "outward" and "externally" refer to a general direction against the plane equatorial tire and towards the tire sidewall. Thus, when the relative directional terms such as "internal" and "external" are used with respect to an element, the "internal" element is less distant from the tire's equatorial plane than the "external" element.
    [0022] Figure 1 illustrates a cross section of a tire 100 modality having an electronic device 105 embedded in it. In the illustrated embodiment, tire 100 includes a circumferential tread 110 and a pair of side walls 115 including a first side wall 115a and a second side wall 115b. The first side wall 115a extends from a first region of the bead 120a to the circumferential tread 110. The second side wall 115b likewise extends from a second region of the bead 120b to the circumferential tread 110. Each region of the bead includes a bead 125a, b and a bead fill 130a, b having an apex 135a, b.
    [0023] Tire 100 additionally includes a carcass tarpaulin 140 extending from the first region of bead 120a to the second region of bead 120b. While only a single carcass tarpaulin 140 is shown in the illustrated embodiment, it should be understood that two or more carcass tarpaulins can be employed.
    [0024] The carcass tarpaulin 140 wraps each of the beads 125a, b, thus forming a first fold portion 145a and a second fold portion 145b. The first fold portion 145a ends at a first fold end 150a located axially outside the first bead fill 130a and radially below the apex 135a of the first bead fill 130a. Similarly, the second fold portion 145b ends at a second fold end 150b located axially outside the second bead fill 130b and radially below the apex 135b of the second bead fill 130a.
    [0025] In the illustrated embodiment, tire 100 additionally includes a belt 155 and a nylon belt 160. In an alternative embodiment (not shown), the tire may include two or more belts. In another alternative mode (not shown), the tire may include two or more nylon straps. In yet another alternative embodiment (not shown), the nylon strap can be omitted.
    [0026] With continued reference to Figure 1, tire 100 additionally includes a first metallic reinforcement 165a in the first region of the bead 120a and a second metallic reinforcement 165b in the second region of the bead 120b. Each metal reinforcement 165a, b involves the respective bead 125a, b and part of the respective bead fill 130a, b and carcass canvas 140. The metal reinforcements 165a, b can provide a structural reinforcement to the tire 100, or they can protect the carcass canvas 140 against abrasion. However, it must be understood that the metal reinforcements 165a, b do not need to fulfill these functions. In an alternative mode (not shown), the metallic reinforcement can be omitted.
    [0027] Tire 100 also includes a pair of reinforcement padding 170, including a first padding 170a located axially outside the first padding of bead 130a and a second padding 170b located axially outside the second padding of bead 130b. Each reinforcement filler 170a, b has an upper end disposed below the apex 135a, b of the respective bead fill 130a, b and radially above the fold end 150a, b of the respective fold portion 145a, b of the carcass canvas 140.
    [0028] Tire 100 additionally includes a pair of abrasion portions 175, including a first abrasion portion 175a and a second abrasion portion 175b. Each abrasion portion 175 involves, at least partially, a bead 125 and the bead fill 130 so that each abrasion portion includes a first portion disposed axially outside a respective bead fill 130, reinforcement fill 170 and bend portion 145 of the carcass tarpaulin 140. Each abrasion portion 175 additionally includes a second portion disposed below a respective bead 125.
    [0029] The electronic device 105 is arranged in one of the regions of the bead 120 at a location radially below the apex 135 of the respective bead fill 130 and axially out of the bead fill 130. The electronic device 105 is axially spaced from the bead fill 130 so that the electronic device 105 does not come in contact with the filling of the bead 130. While the illustrated mode shows the electronic device 105 disposed on the right side of the tire 100, it must be understood that the electronic device can be disposed anywhere of the tire. It should also be understood that a tire could have multiple electronic devices, such as a device arranged on each side of the tire.
    [0030] Figure 2 is a schematic drawing of an embodiment of an electronic device 105. In the illustrated embodiment, the electronic device 105 is an RFID tag that has a passive RFID transponder 180 and a pair of antennas 185a, b that forms a dipole. The radio frequency identification (RFID) tag can be embedded in a material, such as rubber or other polymeric material. Alternatively, a smooth radio frequency identification (RFID) tag can be used. It must be understood, however, that the illustrated modality is merely exemplary and any electronic device can be used.
    [0031] In one embodiment, the electronic device 105 is oriented in a substantially circumferential direction.
    [0032] Figure 3 illustrates a cross section of one of the regions of bead 120 of tire 100.

The inner portion of the metal reinforcement 165 has an inner end that ends radially above bead 125 and radially below apex 135 of bead fill 130. The outer portion of metal reinforcement 165 has an outer end radially above bead 125 and radially below bend end 150 of bend portion 145 of carcass canvas 140. However, it should be understood that the illustrated metallic reinforcement is merely exemplary and that the inner and outer ends can be arranged in any location. In an alternative mode (not shown), the metallic reinforcement can be omitted.

    [0054] With respect to the term "includes" or "including" used in the specification or in the claims, it is intended to be inclusive in a similar way to the term "comprising" as that term is interpreted when used as a transition word in a claim. In addition, with regard to the use of the term "or" (for example, A or B) it is meant to mean "A or B or both". When applicants wish to indicate "only A or B, but not both" then the term "only A or B, but not both" will be used. Thus, the use of the term "or" in this document is inclusive and not exclusive. See Bryan A. Garner, A Dictionary of Modern Legal Usage 624 (2nd edition 1995). In addition, with regard to the term "in" used in the specification or in the claims, it is intended that it also means "no" or "na". In addition, with regard to the term "connect" used in the specification or in the claims, it is intended that it means not only "directly connected to", but also "indirectly connected to", as if it were connected through another component or other components.
    [0055] Although the present application has been illustrated by describing the modalities of it, and although the modalities have been described in considerable detail, the claimants do not intend to restrict or in any way limit the scope of the claims attached to such details. The advantages and additional modifications will be readily apparent to those skilled in the art. Therefore, the request, in broad aspects, is not limited to specific details, representative methods and mechanisms and examples and illustrations shown and described. Therefore, deviations from such details can be made without departing from the spirit or scope of the applicant's general inventive concept.
