Abstract: The present invention relates to a motorcycle anti-tipover device that has telescoping support arms that extend to the ground. The support arms are automatically extending when the motorcycle is stationary or moving at low speeds to prevent the motorcycle from tipping over. The telescoping support arms may also serve as a traditional kickstand, or may be used to lift the motorcycle during servicing. Alternatively, an airbag may be deployed underneath the motorcycle to prevent the motorcycle from tipping over.

Abstract: A well pumping system includes a pivotally mounted walking beam and "horsehead" connected to a downhole pump by a pump rod in the conventional manner. A hydraulic lift piston and cylinder and a pneumatic balance piston and cylinder are connected to the walking beam. A process control computer controls input signals to a hydraulic control valve for controlling the hydraulic cylinder rate and direction of travel to provide corresponding control over the motion of the walking beam. The computer receives input information from a position sensor indicating the displacement of the beam in its range of travel. The computer program also is responsive to a timer for determining actual stroke rate and acceleration of the beam. The computer monitors and controls operation of the hydraulics and pneumatics as the pumping unit produces the lift necessary to extract fluid from the well.
