Abstract: A method of changing the aerodynamic drag on a vehicle (14) having at least one adjustable air deflector (10, 110, 30, 46) includes disposing an air drag sensor (50) on an outside surface of the vehicle to measure an air drag value “Value”, comparing the air drag value with a predetermined value “y”, and adjusting the air deflector when the air drag value is either less than or less than or equal to the predetermined value.

Abstract: A vehicle has a fluid center that comprises a cowl tray mounted to the cowl structure of its operator cabin below a lower end of the windshield of the operator cabin. In addition to a cowl tray the fluid center comprises a fluid reservoir and/or a fluid-center-mounted engine-air-intake duct with an inlet that is directly or indirectly in fluid communication the atmosphere and an outlet that is in fluid communication with other engine-air-intake ducts of the vehicle.

Abstract: A child's ride-on vehicle including a molded plastic body member with a wheel-mounting assembly including a frame member. The wheel-mounting assembly is mountable to the body member with the frame member adjacent the body member. A tongue extends downwardly from the body member to be received by a pocket formed in the frame member so that the tongue fits into the pocket as the wheel-mounting assembly is mounted to the body member, with the tongue fitting closely within the pocket when the wheel-mounting assembly is mounted to the body member, the tongue and pocket thereby establishing alignment between the wheel-mounting assembly and the body member.

Abstract: An identification tag for various size lube oil plugs for mobile vehicles. The identification tag has a mounting hole with an intentional flash in each comer. Each side to the hole has a flap with a living hinge adjacent. The living hinges run between the flashes. The flaps will pivot on installation to allow engagement of the inner edges of the flaps on receiving slots of the receiving slots of the various size lube oil plugs.

Abstract: A children's riding vehicle includes a compartment-enclosing member which may be pivotably opened and closed, and pinch relief structure thereon for preventing a child from pinching a finger when the enclosing member is closed. The structure includes an arm joined to the enclosing member adjacent an edge thereof so that it is movable therewith when the enclosing member is opened and closed. A slot in the vehicle receives the arm and permits it to move when the enclosing member is opened and closed, and further allows the arm and the enclosing member to be selectively moved, together as a unit and relative to the vehicle, for defining a space between the edge of the enclosing member to which the arm is joined and the vehicle, for preventing a child from pinching a finger when the member is closed.
