Abstract

A monitoring device and patch assembly includes a patch that removably and re-attachably holds the monitoring device. The patch is adapted to connect the monitoring device to a pneumatic tire when the monitoring device is held by the patch. The patch is configured to hold a monitoring device having a rounded outer surface. The patch holds the rounded monitoring device by having a resilient tube with an outlet having a diameter smaller than the diameter of the monitoring device. The monitoring device of the invention includes a feature that allows it to be removed from the patch.

35. The tire monitoring device of claim 34, wherein the sliding engagement between the tag assembly and patch results in a portion of the patch fitting snugly between the two opposed sliding surfaces of the tag assembly, thereby preventing movement in a direction other than the sliding direction.

36. The tire monitoring device of claim 33, wherein the patch has a substantially planar surface configured to engage the inner surface of the tire, and the two opposing linear sliding surfaces form a portion of a member configured to extend inwardly from the substantially planar surface when the device is mounted in the tire.

37. A tire monitoring device configured to be mounted in a tire, the tire monitoring device comprising:

a tag assembly including an electronic monitoring device and a rigid protective layer, the tag assembly including an opening; and

a patch configured to be permanently mounted to an interior surface of the tire, the patch including a projection configured to selectively engage the opening in the tag assembly such that the patch and the tag assembly can be removably connected together by sliding either the tag assembly or patch relative to one another.

38. The tire monitoring device of claim 37, wherein the tag assembly is formed by using a mold having two halves, a liquefied material being provided in the mold surrounding the electronic monitoring device and allowed to subsequently solidify into the rigid protective layer.

39. The tire monitoring device of claim 37, wherein the sliding engagement between the tag assembly and the patch act to secure the tag assembly and patch together as a combined assembly with no movement therebetween in a direction other than the sliding direction.
