  • Publication number: 20110192221
    Abstract: A valve for a tire pressure monitoring system in which the valve acts a coaxial conductor to transmit a signal to a receiver presented. A valve stem electrically isolated from a valve pin form the coaxial conductor. In a tire pressure monitoring system, a tire pressure measurement module is positioned inside a tire. In one embodiment, a conductive radiating structure is electrically connected or coupled to the valve pin to receive the tire pressure information signal and transmit it to a receiver. The above configuration further permits a rechargeable battery in the tire pressure measurement module to be recharged via the tire valve. The valve pin and valve stem, being electrically isolated from one another, are used as recharging paths for the battery.

    Abstract: A runout gauge includes a stand (such as a tripod), and a gauge bar pivotally mounted on the stand. The gauge bar includes a wheel on its upper end positioned above the pivot for rollingly engaging an outer surface of a vehicle tire, and further includes a pointer located a greater second distance below the pivot. By this arrangement, movement of the wheel on the tire due to runout causes the pointer to move along an amplified path having a length greater than the movement of the wheel, thus making it easier to read. The illustrated stand includes indicia for measuring movement of the pointer, and also includes gauge slides on a frame component that abut the pointer in a manner showing an extent of the pointer's movement, which relates to the runout on the tire.

  • Patent number: 7669466
    Abstract: Tire sensor packaging capable of being installed on a standard snap-in tire valve stem is provided. The sensor package includes an attachment member capable of being disposed in the flexible bore of a snap-in tire valve stem, and of securely engaging with the inner wall of the flexible bore. The attachment member can be an integral part of the sensor package, or it can be a separate part that acts as an expansion device (e.g., an expansion nut) when engaged with the sensor package. Preferably, the attachment member includes features, such as barbs, to provide more secure engagement with the tire valve stem. Packages according to embodiments of the invention include a package passage (e.g., a channel or a bore) to permit the flow of air past the sensor, so that the tire can be inflated or deflated. Sensors can be attached to the tire valve stem before or after the tire valve stem is installed in the wheel.

  • Patent number: 7607346
    Abstract: A tire pressure indicator (TPI) (10) that provides a method by which the air pressure in vehicle tires can be easily and reliably checked to determine if the tires are optimally inflated. The TPI (10) is comprised of a valve core (12) that replaces a conventional tire-valve core that is inserted into a vehicle tire stem (170). The valve core (12) includes a diaphragm (64) that controls the vertical displacement of a plunger shaft (80) that controls the contact position of a switch (S1). From the switch (S1) a high or a low tire-pressure signal is transmitted to a tire pressure monitoring unit (160), from where an individual can observe and correct the tire pressure. The TPI (10) features a structure and a method by which false tire pressure signals caused by changes in ambient temperature and normal tire temperature fluctuations are eliminated.
