Abstract:
A housing for a tag assembly comprises an internal chamber defined by sidewalls and a bottom wall; a peripheral flange projecting from the housing; convergent surfaces extending at an upper housing end to an upper surface; and a sensor portal projecting through the housing upper surface in communication with the housing chamber. The housing is positioned within a mold block with the upper housing end resident within a mold block cavity. An upper surface of the peripheral flange and housing sidewall superior to the flange abut sidewall portions of the mold block to isolate the upper housing end with the cavity while carrier strip material is induced into the mold to partially embed the housing therein. An annular apparatus is thus formed comprising an annular carrier strip having a transponder housing at least partially embedded therein in which an upper housing end remains free of the carrier strip.
Abstract:
A device for detecting the tire pressure of a motor vehicle tire (6) has an electronic unit (1) with an antenna (2) that is connected therewith. The electronic unit (1) and the antenna (2) are mounted on an elastic, circular support (3), which is fixed coaxially to the wheel axle (8) on the tire sidewall (7) in proximity of the wheel rim (5). The support (3) is fixed to the tire (6) only with its inner circumferential side while the outer circumferential side protrudes freely into the interior of the tire.
Abstract:
A method of effecting an improved adhesive bond between a rubber surface and a device adhered thereto is disclosed. In pneumatic tires, monitoring devices are more securely adhered to the innerliner of the tire utilizing a room temperature vulcanizable adhesive wherein curing is facilitated in the presence of moisture. The innerliner formulation is prepared by incorporating a material which has incomplete compatibility with the rubber of the innerliner formulation, and which has hygroscopic properties which thereby tends to attract moisture.
Abstract:
A tire and electronic device assembly is disclosed, the electronic device measuring one or more tire parameters. The electronic device attaches to a cellular insert member to create a sub-assembly, the insert member having an inward surface attached on a centerline of the tire to an inward facing tire surface defining a tire cavity. The electronic device attaches to the cellular insert member between raised regions of the cellular insert member with an outward surface of the device uncovered and exposed and recessed below outward boundaries of the raised regions.
Abstract:
A tandem tractor and trailer system includes a tractor having a cab and a trailer, each having multiple wheel units, each wheel unit having a mounted tire and a tractor tire pressure measuring device. A first display unit mounts within the cab of the tractor and a second display unit to the exterior of the trailer, each display unit operating to communicate to an operator of the tractor a visible indicia of tractor and trailer tire inflation pressure status, respectively, based upon pressure measurements of the tractor and trailer tire pressure measuring devices, respectively. The second display unit may mount to a forward end of the trailer at a mounting location operatively visible by differentiated colored light emission through a rear view mirror to the operator of the tractor during operation of the tractor and the trailer. The system may include one or more receivers operatively mounted to the tractor and trailer to receive measured tire inflation pressure data from the tractor and trailer tire pressure measuring devices, respectively, and communicate the received measured tire inflation pressure data by hard wire or wireless transmission to a common shared or local data processing unit(s).
Abstract:
A system and method for post-cure application of electronics to a tire includes: a first stage assembly in which an ends of an annular antenna wire are positioned within conductive grommets in a base member; a second stage in which a plug is affixed to the base member to hold the antenna ends in place during shaping and curing of the antenna wire into a tire; and a third stage in which the plug is replaced by a tag carrier, the carrier including means for establishing and maintaining electrical contact between the antenna ends and the tag.
Abstract:
A tire and wheel rim assembly includes a tire supporting rim having an outward facing mounting surface; a tire mounted to the rim positioning an internal tire cavity over the rim mounting surface; a passageway extending through the rim for communicating air pressure between the tire cavity and a side of the rim opposite the tire cavity; and means for controllably regulating the flow of air through the passageway. A connecting member such as a bolt may extend through the rim outside mounting surface to affix a tire pressure monitoring housing to the rim and the axial passageway through the rim may be an axial bore through the bolt. Regulation of air flow through the passageway may be effected by setting the diameter of the passageway sufficiently small; or incorporating a needle orifice in the passageway; or incorporating a porous insert body into the passageway. The insert body may be composed of sintered metal and may be fused to the internal sidewalls of the bolt.

Abstract:
Methods of monitoring tire pressure and responding to a tire pressure error. A tire pressure monitoring apparatus provides signals to a vehicle control representing pressures in respective ones of the tires. The vehicle control first detects a tire pressure error in one of the tires, and then presents to a user a first signal representing the tire pressure error in the one of the tires. Then, a user input representing a prospective tire filling activity is detected. Thereafter, a second signal is presented to the user in response to a pressure in the one of the tires being substantially equal to a desired tire pressure.
