Abstract: A carrier tape, cover tape or static shielding bag for transportation of electronic components is constructed of polymers and carbon nanotubes being between 0.01% and 3% by weight. The carbon nanotubes may have any number of walls and any desired size of diameter dimension which is less than approximately 100 nm. The carrier tape, cover tape or bags including the carbon nanotubes have a static dissipative range measured between 1×105 and 1×1012 ?/sq and a light transmittance value of between 60% and 90%. The carrier tape, cover tape or bags including the carbon nanotubes reduce surface defects, high density entanglements and agglomerations. The static shielding bags including the carbon nanotubes may be formed as sheets which are manufactured into a desired size of bag.

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.
