    Abstract: Joints for connecting a first blade segment to a second blade segment of a wind turbine rotor blade include a first bolt comprising a first proximal end connected to the first blade segment and a first distal end connected to the second blade segment, a second bolt comprising a second proximal end connected to the first blade segment and a second distal end connected to the second blade segment, and a third bolt comprising a third proximal end connected to the first blade segment and a third distal end connected to the third blade segment. At least two of the first bolt, the second bolt and the third bolt differ in size, and a first distance between the first bolt and the second bolt is different than a second distance between the second bolt and the third bolt.

    Abstract: A blind shear ram includes an upper carrier including an upper blade and a lower carrier including a lower blade. The upper carrier and the lower carrier are positionable in a first position in which the upper carrier and the lower carrier are spaced apart and a second position in which the upper carrier and the lower carrier seal a wellbore. The upper blade and the lower blade are configured to cut at least one pipe and at least one cable when the upper carrier and the lower carrier move between the first position and the second position. At least one of the upper blade and the lower blade includes a textured surface configured to induce friction between the at least one cable and the blade.

    Abstract: A system and method for reducing or increasing the mechanical structure resonance of a synthetic jet device is disclosed. A synthetic jet device includes a first plate, a second plate spaced apart from the first plate, a spacing component coupled to and positioned between the first and second plates to form a chamber and including an orifice therein, and an actuator element coupled to at least one of the first and second plates to selectively cause deflection thereof, thereby changing a volume within the chamber so that a series of fluid vortices is generated and projected out from the orifice of the spacing component. At least one of the first and second plates includes a modified section that alters a mechanical resonance of the synthetic jet device, so as to control a level of acoustic noise generated by the synthetic jet device.

    Abstract: A Coriolis flow meter is provided. The Coriolis flow meter includes at least one conduit configured to channel a flow of fluid therethrough, at least two pickup sensors, each pickup sensor coupled to the at least one conduit at a different location, and a drive system configured to oscillate the at least one conduit in a first excitation mode and a second excitation mode. Each pickup sensor is configured to generate a feedback signal including phase shift measurement data corresponding to the first and second excitation modes.
