Abstract: A shape memory alloy (SMA) actuator assembly (1) comprising: a movable part (100); a support structure (3); one or more SMA wires arranged, on contraction, to tilt the movable part relative to the support structure about two orthogonal axes that are perpendicular to a primary axis (O) of the support structure; and axial translation constrainers (16) configured to limit axial translation of the movable part relative to the support structure along the primary axis of the support structure, wherein the axial translation constrainers are arranged to prevent all points of the movable part from simultaneously reaching their most extreme position along the primary axis of the support structure allowed by the range of possible tilt of the movable part relative to the support structure.

Abstract: A display screen assembly is provided comprising a blue light protection transparency. The transparency comprises an additive, such that the blue light protection transparency blocks greater than 50% of light of a wavelength range of 380 nm to 418 nm from passing through the blue light protection transparency as measured by ultraviolet-visible spectroscopy; and the blue light protection transparency blocks 20% to 45% of light of a wavelength range of greater than 418 nm to 430 nm from passing through the blue light protection transparency as measured by ultraviolet-visible spectroscopy. Additionally, the blue light protection transparency has a total visible light transmittance greater than 65% as measured according to ASTM D1003-07 Procedure B.

Abstract: The invention relates to a method for starting up a gas turbine engine of a combined cycle power plant. The method includes applying load to the gas turbine engine and increasing the load until a predetermined combustor firing temperature is reached, while keeping the adjustable inlet guide vanes in a start position adapted to reduce the mass flow of air into the compressor; further increasing the load of the gas turbine engine while opening the adjustable inlet guide vanes and keeping the predetermined combustor firing temperature constant until the inlet guide vanes reach an end position adapted to increase the mass flow of air into the compressor; further increasing the load of the gas turbine engine while keeping the adjustable inlet guide vanes in the end position until a predetermined load of the gas turbine engine is reached.

Abstract: A method performed on a client computing device for providing a graphical user interface for searching through topics and user profiles. It includes rendering, the graphical user interface comprising a first search node, associated with a first node data structure; receiving user input corresponding to a selection of one of the first plurality of nodes as a second search node; and node position input of the second search node; transmitting, a selection request corresponding to the node selection of one of the first plurality of nodes; receiving, data relating to a second plurality of node data structures associated with the second search node; generating on the graphical user interface the second search node at a location on the graphical user interface corresponding to the node position input; and a linking member connecting the first search node to the second search node.

Abstract: A transparency, e.g. an aircraft laminated windshield, includes one or more moisture sensors to monitor moisture penetration to monitor performance of the moisture barrier. The moisture sensor includes a moisture corrodible article or sensor element, e.g. a strip or wire, which changes resistance as a function of corrosion. The sensor element can also include two dissimilar metals, e.g. a bimetal sensor element, or two similar metals having different physical dimensions. With the information provided by the moisture sensors performance of the windshield is available to schedule timely repair or replacement of the windshield that is performing outside of acceptable limits.
