Abstract: Fast Arm-Swing Tether supports lower arms and allows a runner or walker to maintain maximum stride frequency. Tethered thumbs/hands raise natural frequency of pendulum motion of arm swing to ensure that stride rate is not limited by slow arm movement. The tethers keep hands and arms up and reduce lower-arm moment of inertia, thus allowing the lower arms to swing essentially as point masses, resulting in a higher natural frequency of pendulum motion of arm swing to ensure stride frequency is not limited by slow arms. Supporting the hands also reduces effort required to swing arms or to keep elbows locked. This invention relieves arm fatigue for long distance running or walking in addition to allowing greater arm movement. Fast Arm-Swing Tether could be made in any fashion as long as a frontal extension can provide adequate support to hang pendulum tethers to keep hands elevated.

Abstract: Minimized Wave-zone Buoyancy is a new approach to oil and gas platform design with superior construction and performance characteristics compared to state-of-art off-shore drilling and production platforms. Minimized Wave-zone Buoyancy platforms capitalize on low cross sectional area of the portion of the platform exposed to waves. The low cross sectional area reduces buoyancy forces that result from vertical platform movement, enabling the platform to oscillate at a low natural frequency. The low cross sectional area also minimizes the cyclical vertical forces induced by waves. Compare to current designs, application of the Minimized Wave-zone Buoyancy concept will result in a lower natural frequency of oscillation, lower overall weight of platform, or both. Minimized Wave-zone Buoyancy offers an attractive alternative with improved platform stability, fatigue considerations, lower construction and installation costs, and shorter implementation schedule.

Abstract: Structural Additions for Boosting Lateral Effectiveness improves on existing suspension systems to resist car-body rotation during turns around curves. Lateral structural additions increase the separation of springs and shock absorbers to increase a vehicle's rotational stiffness against rolls caused by lateral inertial forces. Vertical structural additions change the magnitude and direction of the moment that causes a vehicle's body to roll. The combination of lateral and vertical structural additions allows the design of vehicle suspension systems that can provide simultaneously smooth ride and good turning performance.

Abstract: The main part of this engine is a rotor (20), driven by circular and tangential fluid flow. Coupled with a counter rotator (30) and stator (40), more work is extracted from the fluid flowing out of the rotor. In application as a gas burning engine, a compressor section is added and is attached to the rotor and counter rotator. Because of the circular and tangential direction of fluid flow, the bulk of the energy of the fluid is converted to rotation and torque, resulting in minimum thrust being generated directly by the engine; however, the rotation and torque produced by the engine could be used to produce thrust.
