    摘要: The present invention is a fish passage system for use at dams. It may incorporate one or more reversible pump-turbines for controlling and generating power from downstream flow of water and fish and for pumping water and fish upstream. For low head embodiments the system may use water stored at above headwater elevation in lieu of a reversible pump turbine for moving fish and water from tailwater to headwater.

    摘要: The present invention relates to inflatable bladder actuated water control gates for control of open channels such as rivers and canals and for control of dam spillways without the need for intermediate piers. The air bladder and hinge flap wedge clamping system includes hinged engagement of the upstream edge of the clamps to the foundation so as to prevent the application of bending and shear loads to the anchor bolts. The resulting configuration facilitates the use of high strength alloy steel anchor bolts in a corrosion protected environment and also prevents tensile loading of the concrete foundation and associated cracking of the concrete foundation.

    摘要: The inventive technology, in its various embodiments, relates to improved multi-axis input devices such as joysticks, and associated multi-axis optical displacement measurement means. Certain embodiments of the input devices may comprise elements movable with respect to each other in at least, e.g., three degrees of freedom and comprise ionically conductive elements that are utilized to generate a position signal in, e.g., at least three, or at least six degrees of freedom. Various ergonomic configurations of six axis joystick embodiments which may be facilitated by the compact design of the transducer means are disclosed. Certain embodiments of the input device technology may provide feedback (e.g., relative to force applied to an item whose position is controlled by an operator) to the operatore. Means for dynamically adjusting coordinate transformations for construction machinery control are also disclosed.

    摘要: The present invention discloses improved ultraviolet air sterilizers. In accordance with this invention the mean reflected light path of each photon is maximized while turbulence is suppressed in order to uniformly UVC expose all conveyed pathogen particles. This invention discloses novel means of maximizing the utilization of blower power and UVC lamp power toward the destruction of pathogens. The resulting efficiencies facilitate the construction of high flow rate air sterilization systems for large buildings while also facilitating the miniaturization of UVC air sterilization systems for incorporation into personal protective equipment (PPE).
