Abstract: A communication link between a first subsea device and a second subsea device includes a first component positioned upon a distal end of the first subsea device and a second component positioned upon a proximal end of the second subsea device, wherein one of the first and second components comprises an engaged position and a disengaged position, and wherein the one of the first and second components is configured to be displaced from the disengaged position to the engaged position after the first and second subsea devices are engaged.

Abstract: A self-locking plug is provided that includes a lock carried between a sleeve and a core. The sleeve has an anti-rotation feature for reducing axial rotation of the sleeve during at least one of core removal and core installation. The core extends through the sleeve. The lock includes a first component and a second component. The first component has a protrusion that extends radially out to a circumferentially extending interference surface. The second component has an interference tab that is radially biased against the interference surface.

Abstract: A fitting for connecting tubular assemblies according to an exemplary aspect of the present disclosure includes, among other things, a base member defining a first bore configured to receive a tube therein. A retaining band defines a second bore for receiving a portion of the base member. The retaining band defines an engagement feature on a radially outward surface configured to engage a locking mechanism of a fastening member.

Abstract: A fixed vane section for a gas turbine engine includes an anti-rotation slot that receives a pin for maintaining a desired position while providing for movement encountered during operation. The example anti-rotation slot includes a compound radius on inner surfaces to reduce stresses encountered during operation.

Abstract: A portable device for refurbishing an edge of an airfoil is provided that has an edge shaper and airfoil positioners that positively engage the airfoil. A method for refurbishing an edge of an airfoil is also provided that includes the steps of (a) providing the portable refurbishing device; (b) locating the edge shaper and the airfoil edge relative to one another with the positioners; and (c) moving one of the device or the airfoil relative to the other along the airfoil edge.

Abstract: A linear optical broadband signal generator includes primary and secondary optical modulators whose outputs are combined so as to minimize intermodulation distortion of a modulated optical signal. A constant amplitude optical signal is split differentially so as to create primary and secondary power levels, the primary and secondary power levels being inputted into the primary and secondary modulators. An electrical input to one of the modulators is differentially attenuated so as to reduce third order modulation products when modulated outputs of the modulators are combined. In addition, the total modulated optical output power is maximized by adjustment to one of the outputs of one of the modulators so that its phase is more in line with a phase of the output of the other modulator so as to maximize first order products of the combined output.
