Abstract
Abstract According to the invention there is in conjunction with a pneumatic tire ( 10 ′) having an electronic tag ( 100 ) mounted therein with a patch ( 70 ′) having a first side ( 72 ′) for mounting against the innerliner of the tire, a second arcuately-shaped side ( 73 ′) and an internally threaded member ( 71 ′) extending to the arcuately-shaped side ( 73 ′). The electronic tag has a pressure sensor ( 116 ) located at the bottom of a tubular shaped air inlet structure ( 118 ) opening at an upper surface ( 122 a ) of the electronic tag, an internally threaded nut ( 132 ) having one end ( 132 a ) disposed within the electronic tag ( 100 ) and an opposite end ( 132 b ) extending outward from the upper surface ( 122 a ) of the tag, an externally threaded member ( 134 ) threaded into the internally threaded nut ( 132 ) and extending through the upper surface ( 122 a ). The externally threaded member ( 134 ) is threaded into the internally threaded member ( 71 ′) so that the opposite end ( 132 b ) of the internally threaded nut ( 132 ) is abutted against the internally threaded member ( 71 ′) whereby the upper surface ( 122 a ) of the tag ( 100 ) is spaced from the second arcuately-shaped side ( 73 ′) of patch ( 70 ′) ensuring that the air inlet structure ( 118 ) is open to the tire cavity ( 16 ′).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
195 words
In conjunction with a pneumatic tire having a tread, a radially-extending belt disposed radially inwardly of the tread and an innerliner forming the interior surface of the tire cavity, apparatus for mounting an electronic tag within the tire, characterized by: a patch having a first side for mounting against the innerliner of the tire, a second arcuately-shaped side and an internally threaded member extending to the arcuately-shaped side; the electronic tag having a pressure sensor located at the bottom of a tubular shaped air inlet structure opening at an upper surface of the electronic tag, an internally threaded nut having one end disposed within the electronic tag and an opposite end extending outward a distance “d” from the upper surface of the tag, an externally threaded member threaded into internally threaded nut and extending through the upper surface; and the externally threaded member being threaded into the internally threaded member so that the opposite end of the internally threaded nut is abutted against the internally threaded member whereby the upper surface of the tag is spaced from the second arcuately-shaped side of patch ensuring that the air inlet structure is open to the tire cavity.
Claim 2
Dependent Claim

In conjunction with a pneumatic tire having a tread, a radially-extending belt disposed radially inwardly of the tread and an innerliner forming the interior surface of the tire cavity, apparatus for mounting an electronic tag within the tire, characterized by: a patch having a first side for mounting against the innerliner of the tire, a second arcuately-shaped side and an internally threaded member extending to the arcuately-shaped side; the electronic tag having a pressure sensor located at the bottom of a tubular shaped air inlet structure opening at an upper surface of the electronic tag, an internally threaded nut having one end disposed within the electronic tag and an opposite end extending outward a distance “d” from the upper surface of the tag, an externally threaded member threaded into internally threaded nut and extending through the upper surface; and the externally threaded member being threaded into the internally threaded member so that the opposite end of the internally threaded nut is abutted against the internally threaded member whereby the upper surface of the tag is spaced from the second arcuately-shaped side of patch ensuring that the air inlet structure is open to the tire cavity.
Claim 3
Dependent Claim
97 words
Apparatus, according to claim 1 , characterized in that: the electronic tag has a lower surface disposed parallel and at a distance “e” to the top surface, first and second side surfaces each of a length “f” and parallel to each other, and first and second beveled surfaces between the side surfaces and the top surface; and the first and second beveled surfaces ( 122 e, 122 f ) of a length that the distance “e” is greater than the length “f” so that the tag is spaced from the second arcuately-shaped side by a spacing “d”.
Claim 4
Dependent Claim
30 words
Apparatus, according to claim 1 , characterized in that the tubular shaped air inlet structure is surrounded by a porous plug that extends to the top surface of the tag.
Claim 5
Dependent Claim
17 words
Apparatus, according to claim 3 , characterized in that the porous plug is a molded porex part.
Claim 6
Dependent Claim
35 words
Apparatus, according to claim 4 , characterized in that the tag is encapsulated in a encapsulation material so that only the top surface of the porous plug is exposed to pressurized air in tire cavity.
Claim 7
Dependent Claim
20 words
Apparatus, according to claim 5 , characterized in that the encapsulation material is a mixture of epoxy and glass beads.
Claim 8
Dependent Claim
27 words
Apparatus, according to claim 6 , characterized in that the tag has an outer coating of an epoxy filled with an aluminum oxide to provide extra hardness.
Claim 9
Dependent Claim
25 words
Apparatus, according to claim 7 , characterized in that the outer coating is a thermally conductive encapsulant with an aluminum oxide filler for abrasion resistance.
