Abstract: A slip yoke assembly having a shaft sleeve, a yoke sleeve, and a yoke. The yoke sleeve may have a set of yoke sleeve splines that may mate with a set of shaft sleeve splines and permit axial movement of the yoke sleeve with respect to the shaft sleeve. The yoke may be fixedly disposed on the yoke sleeve.

Abstract: A vehicle suspension assembly includes a control rod pivotally connected between a vehicle frame and an axle. The control rod controls longitudinal and vertical movement of the axle. A spring member is pivotally connected to the frame and fixed to the axle. Air spring assemblies are mounted between the axle and frame. The rigidly mounted spring member exerts torsion forces on the axle to counter roll forces and the air spring assemblies provide favorable ride characteristics adaptable to various trailer load conditions.

Abstract: A tandem axle suspension assembly includes a pair of walking beams disposed substantially parallel to a vehicle longitudinal axis supporting first and second axles. A link plate is pivotally attached to each of the walking beams and is pivotal about an axis transverse to the longitudinal axis. A first and a second link include pivotal connections between the link plate and a vehicle frame member. Vertical movement of the walking beams causes a corresponding rotation of the link plate to compensate for longitudinal displacement of the pivotal links with the first and second links and minimize longitudinal displacement of the walking beams.

Abstract: An RFID tag (200) and similar control/sensing unit (300) for a communications system are described. The control/sensing unit has a control element (301) having one or more states, and include an antenna (207) as well as an electrical circuit (201-206) generating a pulse control signal for controlling transmission from the antenna and varying a parameter of the pulse control signal in dependence on the state of the control element (301). Also disclosed is a receiving communication unit in the form of a base unit or system controller for such a communications system, the unit including a receiver (100) for receiving a pulsed RF signal and an electrical circuit (105-106) for detecting a parameter of the pulsed RF signal. An output circuit (107) then produces an output control signal dependent on the detected parameter of the pulsed RF signal.

Abstract: A vehicle suspension system is provided that includes a frame and pair of laterally spaced apart upper control arms pivotally supported by the frame at pivotal connections. A knuckle is connected to each of the upper control arms. A leaf spring is connected to the lower portion of the knuckles at pivotal connections and serves as the lower control arms. The upper control arms extend away from the knuckles, and air springs are arranged between the upper control arms and the frame. A pressurized air system is connected to the air springs to control the air springs for providing desired ride characteristics.

Abstract: A water filter has an elongated base with an inlet opening near one end thereof to which is secured an adaptor ring for attachment to a water faucet. A first outlet opening on the base dispenses unfiltered water and there is a channel defined within the base that leads toward the other end, with an externally-operable valve being included for selecting between unfiltered flow to that outlet and flow down the channel. Located near the other end of the base is a mounting on which sits a water filter cartridge that communicates with the channel, and the cartridge delivers filtered water to a second outlet. A number of features include a color indicator to exhibit degree of cartridge usage, a reversible adaptor ring to accommodate different faucets and there are different aerator structures. Of particular note is the replaceable cartridge which includes a deflector for obtaining better usage of the main filtering material, an exteriorally-mounted first filter and an internally-mounted second filter.
