Abstract: A system for using excess energy of a power generation system and an sCO2 (supercritical carbon dioxide) stream to store and generate power. An air separation unit uses the excess energy to cool and liquify ambient air into liquid nitrogen (L-N2) and liquid oxygen (L-O2). The L-O2 and L-N2 are stored until energy is desired. An L-O2 energy discharge path has an oxygen heat exchanger that vaporizes and heats the oxygen, a combustor that combusts the oxygen and fuel to produce exhaust, and a first turbine is driven by the exhaust to produce energy. An L-N2 energy discharge path has a nitrogen heat exchanger that vaporizes and heats the L-N2, thereby providing expanded nitrogen, and a second turbine is driven by the expanded nitrogen to produce energy. Heat for the heat exchangers on both discharge paths is provided by the sCO2 stream.

Abstract: In an approach to reduce nitrous oxide emissions using predictive urea dosing control, a route is determined. A set of target coverage fractions of ammonia is determined over a set of steps for the route, where the coverage fraction of ammonia is a ratio of stored ammonia to a maximum storage capacity of ammonia in a selective catalytic reduction (SCR) device. An actual coverage fraction of ammonia is determined for each step of the route. The actual coverage fraction of ammonia is compared to the target coverage fraction of ammonia for each step. The urea injection rate is adjusted based on a cost function.

Abstract: Presently disclosed is a power production plant that is operable to store and generate power. In a “charge mode” (when electricity price is low), an air separation unit (ASU) cools and liquefies ambient air into liquid oxygen (LOx), which is then stored in a storage vessel. In a “discharge mode” (when electrical price is high), the stored LOx is used by the power production plant to combust a fuel and form a combustion product stream that can be expanded in a turbine to generate power. The power production plant particularly can utilize carbon dioxide as a recycled, circulating or working fluid so that substantially all carbon dioxide produced in the power production can be captured.

Abstract: An on-board navigation system for an unmanned aircraft system (UAS) operating in an unknown environment. A point-cloud sensor system generates point cloud data representing the unknown environment. An on-board processing system processes the point cloud data to generate both a 2-D occupancy grid and a 3-D voxel map, with the 2-D occupancy grid having cells with known (seen) and unknown data. Additional processing determines an amount of known-to-unknown (transitional) data in each cell, thereby determining unexplored regions. A cost is assigned to each unexplored region, based at least in part on the amount of transitional data in cells of the region. The unexplored regions are then sorted based on their costs, thereby determining an optimal region to explore. The 3-D voxel map is used to find a safe area within the optimal region where the UAS may fly. A flight path to the optimal region is then calculated.

Abstract: Described herein is a beads-free bioprocessor as an automated and cost-effective T cell processing and manufacturing platform. T cells are a core component in CAR T cell therapies for cancer treatment, but are difficult to manufacture to scale in clinically relevant quantities. The 3D bioprocessor provides an alternative device that is scalable, beads-free, easy-to-use, and cost-effective for using CAR T cell therapy in cancer immunotherapy. Besides CAR T cell application, this platform technology has potential for many other applications such as cancer cell isolation.

Abstract: A tribometer and technique for determining torque at a physical interface of multiple rotating components. The tool and technique include aligning components about a rotational axis for independent rotation of each component. The components are in physical interface during the rotating with a resultant frictional torque. The torque may be measured by one or more torque meters during the rotating. This measured torque may be compared against an estimated torque for tool accuracy. Further, parameters such as load, temperature, component material, rotating rpm differentials and others may be varied to determine effect on measured frictional torque.

Abstract: A velocimeter/nephelometer for measuring the three-dimensional velocity and/or size and/or shape of a particle. A set of laser interferometers and a set of photodiode detectors are arranged on a two-dimensional platform. Each laser interferometer produces a laser beam, with the beams intersecting within an inner area of the platform. Two of the laser interferometers produce like-oriented fringe patterns with an angular separation between the propagation direction of their beams of ninety degrees. A third of the laser interferometers produces a beam with the fringe pattern oriented orthogonal to the fringe patterns of the other two laser interferometers. Each detector is positioned and filtered to detect light from an associated laser interferometer, the light having been scattered by a particle as the particle passes through a volume of observation.

Abstract: A method of providing a collision avoiding travel path for an autonomous vehicle. A sensor system obtains stereo image data of a scene in the environment ahead of the normal travel path. This image data is used to generate a disparity image. The disparity image is processed to generate an occupancy map that assigns values to areas of the scene based on levels of visual clutter. The occupancy map is then converted to a potential field, which assigns each pixel in the scene with a force value that corresponds to its proximity to one or more obstacles. These force value are summed and used to modify the vehicle's path is a collision is likely.

The compositions show particularly useful stability such that the DMTS remains stable for therapeutic use at the identified time periods. The compositions are therefore particularly suitable for use in autoinjectors.

A soft catch box is located behind the exit panel such that fragments that pass through the exit panel enter the soft catch box and are decelerated within the soft catch box.

Abstract: A sensor for use in detecting corrosion under insulation (CUI) and a method for deploying the same that does not require removal of cladding and/or insulation. The sensor includes at least a first sensor element formed of a first metal and a second sensor element formed of a second metal, the first and second metals being different. One or a plurality of sleeve members formed of an electrically-insulating material, such as plastic, maintain the first and second sensor elements at a predetermined distance from each other and define at least one sensing region that extends between the first and second sensor elements. The first and second sensor elements are configured to electrically communicate based on a conductive solution being disposed in the at least one sensing region and causing a galvanic current to be induced therebetween.

Abstract: The present invention is directed at the synthesis and characterization of recrystallized HI-6 dimethylsulfate (DMS). The method can comprise dissolving HI-6 DMS in an alkyl-based glycol and adding an antisolvent to recrystallize HI-6 DMS or dissolving HI-6 DMS in methanol and adding dimethoxy ethane or dimethyl formamide as the antisolvent to recrystallize HI-6 DMS. The recrystallized HI-6 DMS indicates a resistance to moisture absorption and/or a DSC melting point onset (MP Onset) at least at or above 160.0° C.

Abstract: A modular component dam. The dam may be configured for pairing with another dam in the form of a closed loop pumped storage hydropower plant. One or both of the dams may be constructed of buttress frames made up of prefabricated modules of predetermined varying dimensions which allow for rapid construction over a period of less than about a year. The modules may be transported to dam sites by standard transportation units such as 18 wheelers. This is facilitated by the modules occupying no more than about 14 feet in vertical height above a surface of a roadway during transport and no more than about 11 feet in horizontal width across the roadway during transport.

Abstract: A seamless fumed silica monolithic integrating cavity device tailored to analyzing a flowed sample. The device is configured to facilitate optical measurements taken from a sample flowed through a cavity of the device. The cavity is defined by a fumed silica monolith with the added feature of a fused quartz lining on the surface of the monolith. This provides an intermediate surface that allows for cleaning and reuse of the highly effective diffuse light scattering fumed silica monolith. The lining may be placed under pressure or vacuum to structurally enhance mechanical integrity of the underlying monolith. Thus, continued or reliably repeated use of the device may be appreciated as well as use in more industrial environments that are prone to vibration. Additionally, while well suited for flow-based sample analysis, a valve of the cavity may be utilized for holding a sample in a temporarily static state for measurement.

Abstract: A re-mixing dispenser for containing and dispensing a liquid. The dispenser may have one or more tubes, each containing a different liquid. At least one of the liquids may be re-mixed in situ, using a special two-piece plunger and plunger rod. A mixing piece of the two-piece plunger is moveable independently of a top piece and has blades that allow it to move through the liquid. A plunger rod is removably attached to the mixing piece and is operable to move the mixing piece up and down within the tube during mixing. The two plunger pieces are joined and moved as a single plunger during dispensing.

Abstract: A sensor for detecting properties of a gas, gas mixture, or a gas or gas mixture containing particles, all collectively referred to as a “gas”. A flow tube contains a pair of electrodes arranged such that at least a portion of the gas flows between the electrodes. A controller applies voltage to the electrodes and measures response data from the electrodes representing the voltage-current relationship between the electrodes while the gas is between the electrodes. Based on the response data, the controller determines a concentration of particles within the gas.
