  • Patent number: 6286819
    Abstract: A vibration damper for a seat suspension system is disclosed with a shock absorber which dampens seat vibrations when the shock absorber is coupled to the seat suspension system. The shock absorber includes a dampening cylinder housing with a dampening piston slidable therein. The dampening cylinder housing is coupled to one of the vehicle and seat, such as to the floor of the vehicle. An elongated latch engaging member, which may be in the form of a dampening piston rod is coupled to the dampening piston. A latch is shiftable between first and second positions. When in the first position the latch engages the dampening rod, and when in the second position the latch disengages the dampening rod. When engaged to the dampening rod, the latch couples the dampening rod to the other of the vehicle and seat so that the shock absorber applies a dampening force to the seat. Conversely, when the latch disengages the dampening rod, the shock absorber is relieved from applying a dampening force to the seat.

  • Patent number: 6092021
    Abstract: A fuel efficiency monitoring and display system for a vehicle dynamically evaluates vehicle performance parameters to detect conditions that cause excessive fuel consumption. The conditions include increased aerodynamic drag due to excessive speed, high RPM, braking and accelerating, excessive idling, and rapid throttle movements. The system dynamically estimates gross vehicle weight, roadway grade and drag factor from monitored parameters and uses these estimates to detect inefficient fuel use. The system indicates to the driver when inefficient fuel use is detected. For example, it displays a measure of excess fuel consumed and messages indicating actions that can be taken to improve fuel economy in response to detecting inefficient fuel use.

  • Patent number: 6004202
    Abstract: A truck cab ventilation system and method is described which includes an air exhaust channel that extends from an upper channel portion adjacent the ceiling at the rear of the cab and through a lower channel portion to an exhaust vent mounted adjacent the floor of the cab over an exit opening in such floor. An inlet vent in the front of the cab produces a positive pressure within the cab which causes flow-through ventilation air flow from the front to the rear of the cab when the truck is moving. As a result, air flows into the upper channel portion of the exhaust channel and out of the exhaust vent through the exit opening to the exterior of the cab. The exhaust vent includes flexible louvers of elastomer which are held by gravity in a closed position and are moved into an open position when air flows out through the exhaust system.

  • Patent number: 5988308
    Abstract: A flexible coupling suitable for use in an automobile exhaust system having axially spaced conduit sections. Upstream and downstream conduit sections are held end to end by an intermediate coupling member. The upstream conduit has a part-spherical end connector that fits within a complementary part-spherical socket of the coupling member. Similarly, the coupling member has a part-spherical end connector that fits within a complementary part-spherical socket of the downstream conduit. The part-spherical connectors permit relative pivotal and rotational movement of the upstream and downstream connectors relative to the coupling member. Each of the part-spherical connectors tapers internally to an annular lip, so that the flow of gas increases to create a venturi effect. The venturi effect establishes a relative vacuum at the junctions between the coupling member and the conduits to oppose escape of gas (such as exhaust fumes) from the coupling.
