Abstract: A blade actuation system comprises at least one motor coupled to a rotor blade for changing the pitch angle of the rotor blade. The motor is configured to wirelessly communicate with at least one flight control computer to modulate the pitch angle. At least one generator may be mounted on a rotor shaft to generate power during rotation of the rotor shaft. The generator may provide power to the motor. The flight control computer is operative to provide control signals to at least one of the generators and motors for regulation thereof. The flight control computer, motor and generator may be configured to wirelessly communicate with one another.

Abstract: An apparatus for forming exterior convex vinyl siding corners for use with external walls intersecting at angles greater than 90 degrees including a vinyl siding corner member with two exterior siding members intersecting in the steady state position at 90 degrees. The exterior corner is of a flexible material such as vinyl and defines two internal slots therein within which one or more expander members is positionable to spread the exterior corner member to an angle greater than 90 degrees and approximately equal to the obtuse angle of the intersection between the first and second surfaces. The expander member may be adjustably movable to vary different angles such as would be used in the external convex corners for mounting of bay windows and other similar obtusely oriented exterior walls.
