Primary leaf springs are each coupled at their respective centers to respective drive shafts by pivotal arrangements. The first and second primary springs may include helical springs that are used in place of, or in combination with, the primary leaf springs. Secondary leaf springs may be splayed and therefore need not be arranged parallel to the primary leaf springs. Control over vehicle kinematics is enhanced by configuring the resilience of a fulcrum bumper using resilient, rheological, or active systems. An active system will control vehicle height while stationary to facilitate loading and unloading of the vehicle.

Wind-hydro power generating system and method
InactiveUS20100289264A1Improve power generation efficiencyWorking fluid for enginesBlade accessoriesRotatory powerEngineering
A wind-hydro power generation system and its power generation method which use both wind power and hydraulic power. Increasing the size of a hydraulic turbine for the hydraulic power generation may result in the decreased rotation power of the hydraulic turbine caused by the resistance of the wind when blades on the hydraulic turbine come out of the water. The present invention has a blade rotation system on the blades of the hydraulic turbine so that the blades may rotate according to the direction of the wind. As a result, wind resistance is not effected to the rotation of the hydraulic turbine even when the blades on the hydraulic turbine are out of water, but enhances the rotation power of the hydraulic turbine, which enables the use of wind power and hydraulic power at the same time.

Variable rate pump
A rotational power input is converted into a linearly oscillating power output through the use of counter-rotating nested eccentrics. The outer eccentric is connected to an input end of a connecting rod, which is in turn connected at an output end thereof to a piston of a piston pump. The piston is constrained to translational movement along an axis D. Drive gears are rotationally fixed to each of the eccentrics and geared to each other through an intermediate pinion having a rotational axis B. An angular position beta of the pinion axis B relative to the axis D determines the output oscillation stroke length and flow rate of the pump. An actuator is geared to a pinion bracket that holds the pinion. The actuator can be actuated on-the-fly to alter the angle beta and pumping rate of the pump.

A device known as a Flow Stream Momentum Conversion Device (FSMCD) Power Rotor has been invented. The device makes use of the principle of Conservation of Momentum to convert fluid stream input momentum to device rotational power. A unique and non-obvious aspect of the fluid momentum conversion is circumferential discharge. This aspect maximizes power conversion in a given cross section of open stream flow. Power is extracted from the device as mechanical loading is applied to the rotating shaft resulting in a decrease in rotational speed and an increase is shaft torque. The device has practical usage in both wind and water flows. Under the condition of zero rotor shaft loading the device may be configured to make linear stream measurement of flow speed. This invention has applications in utilizing both unidirectional and bidirectional “fluid stream” flow. It is especially effective in tidal and wave action applications.
