Abstract: An advanced aerodynamic control system for a wind turbine including a drive shaft and blade. The control system includes an air control system coupled to a duct that extends from a first end toward a second end of the blade. A slot extends along a portion of a surface of the blade and is in communication with the duct. An instrument measures operating data of the wind turbine. A controller collects the operating data and compares the operating data to predetermined operating norms. The controller actuates the air control system to urge pressurized air into the duct and out of the slot at a specific air flow rate based upon the comparison between the operating data and predetermined operating norms. Control of the flow rate aids in capture of power from the wind flowing through a swept area of the wind turbine.

Abstract: This invention is an apparatus and process for the reinforcing of concrete, wood, or steel columns, beams, or structures. The apparatus includes pre-made reinforcing layers constructed of engineering materials having a high tensile strength and a high modulus that are attached, via an adhesive, or fitted to the element in question to create a reinforcing shell exoskeleton thus increasing the column's compressive, shear, bending, ductility, and/or seismic load carrying capacity.

Abstract: A low pressure relief valve made of elastomeric material is capable of relieving pressure in fixed and movable systems and is both economical and reliable.

Abstract: A gas pressure regulator useful in controlling low pressures in the range of 0 to 100 psig is economical, effective and efficient and can be used to control fixed or variable outlet pressures.
