Abstract: Aspects of the present disclosure describe systems, methods, and structures for aberration correction of optical phased arrays that employ a corrective optical path difference (OPD) in the near-field of an OPA to correct or cancel out aberrations in emitted beams of the OPA including those reaching far-field distances by generating a spatially-varying OPD across the aperture of the OPA that is substantially equal and opposite to an equivalent OPD of the aberration(s).

Abstract: Systems, methods, and devices for post-processing additively manufactured objects are disclosed herein. In some embodiments, a method includes receiving a plurality of additively manufactured objects on a rotor, the plurality of additively manufactured objects having excess material thereon. The method can include removing the excess material from the plurality of additively manufactured objects by rotating the plurality of additively manufactured objects via the rotor. The method can further include applying energy to the plurality of additively manufactured objects to cure a portion of each additively manufactured object while the plurality of additively manufactured objects are on the rotor.

Abstract: The present invention relates to a method of depositing a coating comprising zinc oxide on a substrate; to a chemical vapour deposition precursor mixture for use in same and to a coated glass article and a photovoltaic cell prepared with a zinc oxide coating prepared using the method which comprises: providing a substrate, providing a precursor mixture comprising an alkyl zinc compound and a phosphorus source, the phosphorus source comprising a compound of formula OnP(OR)3, wherein n is 0 or 1 and each R is hydrocarbyl, and delivering the precursor mixture to a surface of the substrate.

Abstract: A power generation and/or storage apparatus comprising a buoyant flywheel, wherein the flywheel is arranged, in use, in contact with a body of liquid for rotation about a substantially vertical axis, an underside of the flywheel comprising a circumferentially extending opening, wherein, in use, gas is trapped within the opening by the surface of the liquid to define an gas cushion for supporting the flywheel.

Abstract: A tidal barrage comprising: a plurality of spaced towers, a plurality of barriers for controlling water flow through the barrage between the towers, and one or more turbine devices, wherein the towers comprise at least first, second and third towers, wherein the first tower is located between the second and third towers and houses one or more of the turbines, wherein one or more first barriers are provided between the first and second towers, and one or more second barriers are provided between the first and third towers, wherein the barriers are configured so that when the one or more first barriers and the one or more second barriers are in a first configuration, a first flow path through the barrage is defined from a first side of the barrage to a second side of the barrage, and when the one or more first barriers and the one or more second barriers are in a second configuration, a second flow path through the barrage is defined from the second side of the barrage to the first side of the barrage, and wate

Abstract: Disclosed are systems and methods for generating graphical displays of analyte data and/or health information. In some implementations, the graphical displays are generating based on a self-referential dataset that are modifiable based on identified portions of the data. The modified graphical displays can indicate features in the analyte data of a host.

Abstract: An anti-collision system for railcars and locomotives provides a distance ranging and worker coupling protection system utilizing remote-sensing radar techniques for use with a locomotive and railcar. The anti-collision system may include an object detector device attached to a railcar or a locomotive that detects objects in a path of the railcar and the locomotive and a train display device electrically connected to the object detector device. The anti-collision system may also include an emergency action device which enables a crew member to stop the railcar or locomotive without communication to a locomotive operator when a hazard is recognized. The object detector device may include a remote sensor, a radio, and a microprocessor programmed to include data-logging to record and log all data from the anti-collision system.

Abstract: A sign mounting for mounting a sign on top of a barrier post that includes a body having an inner side for positioning against a barrier post and an outer side for supporting a sign; and a mounting channel formed on the inner side of the body. The mounting channel allows the sign mounting to be mounted onto and supported by a spline of the barrier post. The mounting channel is open at a lower end and closed at an upper end and has a relatively narrow vertical opening at an inner side extending from the lower end to the upper end for a spline to extend through, and a relatively wider inner portion extending laterally beyond the opening on each side of the vertical opening within which a spline can be positioned. The sign mounting may form part of a mounting kit that includes a barrier post.

Abstract: Methods and systems for removal of ions from aqueous fluids are provided. In certain embodiments, the present disclosure provides a method of removing one or more oxyanions from an aqueous fluid, including the steps of contacting an aqueous fluid containing oxyanions with an aluminum metal whereby aluminum ions are released from the aluminum metal into the aqueous fluid, wherein the one or more oxyanions in the aqueous fluid react with the aluminum ions to form one or more ettringites; controlling a rate of release of the aluminum ions from the aluminum metal; and removing at least a portion of precipitated ettringites from the aqueous fluid.
