Abstract:
A method and apparatus for connecting an electronic monitoring device to a pneumatic tire includes mounting the monitoring package of the monitoring device within the body of the tire or the body of a patch and subsequently connecting the power source to the monitoring package through electrical coupling. The method allows the monitoring package to be cured within the tire or the patch at relatively high temperatures while protecting the sensitive power source from the high temperatures. The use of electrical coupling to achieve the power transfer prevents the material surrounding the monitoring package from being pierced by an element that would form the direct electrical connection. The method allows the monitoring package and its antenna to be positioned in a variety of positions on or within the pneumatic tire.
Abstract:
A method and apparatus for connecting an electronic monitoring device to a pneumatic tire includes the steps of providing a green tire and attaching the electronic monitoring package to an anchoring patch. The anchoring patch having the electronic monitoring package is then mounted to the green tire and cured during the green tire cure process. A battery is then provided and a direct electrical connection between the electronic monitoring package and battery is then formed by plugging the battery into the electronic monitoring package. The electronic monitoring package may also be mounted in the green tire itself and cured with the green tire. The battery is connected to the electronic monitoring package after the cure process.
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.
Abstract:
A method and apparatus for generating various tire profiles. A linear-linear-rotary table carries a non-contacting probe that sequentially scans the entire outer surface of a tire. The non-contacting probe collects measurement data which is transferred to a processor to generate an average cross-sectional tire profile or a high definition cross-sectional tire profile of the tire being measured. The processor, in conjunction with the non-contacting probe, provides an automatic ranging feature which eliminates the need to manually adjust the non-contacting probe prior to the collection of measurement data.
Abstract:
An apparatus and method uses a pair of transducers, such as lasers, mounted on the tire/wheel assembly of a mowing vehicle for measuring the actual angles of camber experienced by the vehicle tire as the vehicle moves along an actual road surface. The pair of lasers are mounted in a predetermined horizontal spaced relationship on a bracket mounted on and extending perpendicularly outwardly from a non-rotating hub mounted on the tire/wheel assembly. The reflected laser beams from the pair of lasers are continually measured as the vehicle moves along the road surface. The reflected beams determine the change in spacings of the two lasers above the road surface from which can be calculated the angles of camber continuously imparted on the tire/wheel assembly. This data is collected and stored in a computer located in the vehicle and captures the tire's operating camber angles with respect to an actual road surface when used on a particular vehicle. The stored data is later supplied to tire test equipment at a remote test facility to duplicate the actual road camber experienced on the test tire on other test tires at the test facility to simulate the real-world environment for a particular tire on a particular vehicle without repeating the more costly tests on the actual moving vehicle at a remote test track.
Abstract:
A tire monitor assembly includes a rubber ply having a first side affixable to an interior surface of a tire. A pedestal extends from a second side of the rubber ply, wherein the pedestal has a top surface and at least one sidewall. The pedestal has a groove disposed in the at least one sidewall that extends along a perimeter of the pedestal, wherein the pedestal has a cavity disposed in the top surface, extending towards the rubber ply. The assembly further includes a tire monitoring device and a fastener connected to the tire monitoring device and further connected to the pedestal such that the fastener is disposed in at least one of the cavity and the groove.
Abstract:
The invention provides a monitoring device and tire combination wherein an antenna is mounted to the tire in a location spaced from the monitoring device. In one embodiment, the antenna may be mounted to the tire sidewall outside the body cords of the tire. The antenna may be mounted on the outer surface of the sidewall or embedded within the body of the sidewall. The antenna is connected to the monitoring device with a connector. The connector may be electrically coupled to the monitoring device or may be connected to the monitoring device with a plug and socket connection. When the antenna is outside the body cord, the connector may extend from the antenna through the bead filler, over the top of the turn up, or under the bead ring.
Abstract:
A battery operated device includes a receiver for receiving a transmission that includes a postamble. A sensor, in a tire, measures a parameter of the tire and outputs data indicative of the parameter. A microprocessor is coupled to the receiver and the sensor. The microprocessor is configured to periodically partially awaken to determine whether the transmission is likely a forward link packet (FLP) by examining the postamble, and to transmit the data in a reverse link packet (RLP) in response to confirming that the transmission is a FLP.

A sensor system for obtaining data from an air spring having elastomeric body with a plurality of wireless sensors embedded therein. The sensor length-scales range from nano- to micro-scale devices that are small enough to avoid becoming occlusions within the elastomeric body. The air spring may include a spring wall having an internally reinforced elastomeric body portion with the sensors embedded within. The air spring may include a spring wall having an unreinforced elastomeric body portion with the sensors embedded within. The sensors may be configured to provide data related to one or more of temperature, pressure, sidewall flex, stress, strain and other parameters. The sensors may be LCD sensors, and/or conductive polymer sensors, and/or bio-polymer sensors and/or polymer diodes suitable for sensing data during the operation of the air spring.
