  • Publication number: 20020035527
    Abstract: A computer-implemented method, computer program, and Internet web site that provides key investment and planning tools for use by individuals in planning their retirement. The invention provides investors with a complete account analysis and investment advisory report that quantifies meaningful saving goals, determines the effectiveness of the investor's current strategy, establishes investment performance expectations, offers investment guidance, and monitors and reevaluates their progress. Through a form of artificial intelligence, the invention brings the same sophisticated investment analysis techniques used by large pension plans and money managers to the individual investor, allowing him to interpret account statement information from current and previous periods and easily relate it to two quantifiable goals.

  • Patent number: 5251591
    Abstract: A valve is comprised of two parallel passageways running transversely through a cylindrical valve shaft. Several valves are spaced axially in the valve shaft. The valve shaft axially rotates in the upper portion of an internal combustion engine. Each of the valves is positioned adjacent an engine cylinder. Rotation of the valve shaft causes the passageways to allow fluid communication between an engine cylinder and, alternatively, intake and exhaust ports, thereby performing the valving function for that engine cylinder. Two parallel valve shafts are used so that each cylinder is serviced by two valves. The parallel valve shafts and the engine crankshaft are connected to a timing chain assembly which coordinates the rotation of the valves with the translational motion of the engine pistons. A retractable throttle valve is located in the intake port for each valve and controls the amount of the fuel and air mixture flowing through the valve and into the engine cylinder being serviced by that valve.
