Abstract: A three wheeled vehicle that has an improved dual front wheel integrated steering and suspension system that allows the vehicle to be maneuvered by a combination of arm and leg steering movements coupled with front end leaning that shifts the center of mass of the vehicle down and toward the inside wheel. This transfer of mass counteracts a conventional cornering vehicle's tendency to fling its mass to the outside wheel and lift the inner wheel off the ground as well as changing the angle of the line of force exerted through the tires, and enhancing the vehicles's grip on the ground. The vehicle has a reduced amount of sliding and potential of flipping when turning sharply. The steering system is compatible with traditional ACKERMAN steering geometry wherein the inner wheel turns in a smaller diameter circle than the outer wheel.

Abstract: A valve especially designed for use in a prosthetic device such as an artificial limb wherein the limb stump is mounted within a mating socket provided by the prosthetic device and is firmly secured therein by vacuum sealing, the valve being is connected to vent the lower portion of the prosthesis socket when manually actuated. The valve includes a central core section of elastomeric material which is formed with a passageway therethrough for venting the prosthesis cavity and which is formed with an enlarged valve chamber and a valve set facing away from the prosthesis cavity. A valve member is mounted in the chamber and is moveable to and from the set to provide sealed and vented positions respectively. The movement of the valve is controlled by a finger engaging button which is in turn biased by elastomeric nodules to move the valve member to its seat thereby sealing the prosthesis chamber.
