Method and apparatus for removably inserting an electric tire tag into a tire
First Claim
1. A tire having an electronic monitoring device for monitoring at least one engineering condition of a tire and mounted within the tire, comprising:
- a tire having an inner liner;
a separate rubber patch having a first side which includes a housing with a cavity having a preselected configuration and a second opposite side approximating the contour of the tire inner liner, the patch being permanently assembled to the tire by attaching the second side to the tire inner liner;
a tag assembly which includes an electronic monitoring device encapsulated in a rigid potting material and a removable power source, the tag assembly having a shape permitting insertion into the housing cavity of the rubber patch; and
means for removably attaching the tag assembly into place within the housing cavity.

Abstract
An improved method and apparatus permits the insertion and removal of an electronic monitoring device from a tire, while securing the electronic monitoring device to the tire so that stress, strain, impact, cyclic fatigue and vibration are minimized. After a rubber patch is vulcanized, the patch is permanently assembled to the inner liner of a vulcanized tire by affixing it to the tire inner liner. An electronic monitoring device, after having been encapsulated in a suitable rigid potting material to form a rigid tag, is fitted with a power source to form a tag assembly in a shape which allows for insertion into a cavity in the patch. The tag is carefully inserted into the cavity housing. The tag assembly is locked into place within the cavity using a suitable removable locking means.

2. A tire having an electronic monitoring device for monitoring at least one engineering condition of a tire and mounted within the tire, comprising:
-
a vulcanized tire having an inner liner; a separate vulcanized rubber patch of preselected configuration having edges, a first side including a housing having a cylindrical inner surface at least a portion of which is internally threaded, and a second opposite side approximating the contour of the inner liner of the tire, the second opposite side attached to the tire inner liner; and a tag assembly including a rigid potting material encapsulating an electronic module and a battery for providing power, the tag assembly having an outer cylindrical surface corresponding to the cylindrical inner surface of the patch housing, the outer cylindrical surface having sufficient external threads which thread into the internally threaded cylindrical inner surface of the patch housing to removably position the tag assembly in relationship to the patch housing.
