Abstract: A line power control method and system for a unified power flow controller includes outer loop line power control, inner loop valve side current control, and converter valve control. Series-side converter valve side current reference values Isedref and Iseqref are calculated by means of the outer loop line power control according to line power instructions Pref and Qref that are input, a measured line power UL, and measured line power Pline and Qline; a converter output voltage reference value Ucref is calculated by means of the inner valve side current control according to the valve side current reference values that are output by means of the outer loop power control, a measured valve side current, and a measured valve side voltage; and finally, a converter outputs, according to the voltage reference value, a corresponding voltage to control line power to achieve a reference value.

Abstract: A decision support tool to assist decision-making in the operation of a facility. The decision support tool allows a user to perform operational programming of the facility so that the analysis of specific operational events is flexible and “on-demand.” This is achieved by allowing the user to set scope and timeframe of the analysis according to business needs. As a result, the organization can make better-informed judgments whether to add operational activities and how to adjust the ones already formulated in the program. The decision support tool can also allow for the application of strategies to communicate intent behind the programming instructions and to improve the quality of business decisions.

Abstract: A pump head includes a casing unit, a tightening member and a control unit. The casing unit includes a main body and an abutment wall connected to the main body. The main body has an installation section. The tightening member is disposed in the installation section proximally to the abutment wall. The control unit includes a control valve, a resilient member and a control lever. The control valve is movably disposed in the installation section. The resilient member urges the control valve toward the abutment wall to clamp the tightening member between the control valve and the abutment wall. The control lever is connected to the main body and operable to move the control valve against the resilient member and away from the abutment wall.

Abstract: A wearable neck device and a method of operating the wearable neck device are provided for outputting optical character recognition information to a user. The wearable neck device has at least one camera, and a memory storing optical character or image recognition processing data. A processor detects a document in the surrounding environment and adjusts the field of view of the at least one camera such that the detected document is within the adjusted field of view. The processor analyzes the image data within the adjusted field of view using the optical character or image recognition processing data. The processor determines output data based on the analyzed image data. A speaker of the wearable neck device provides audio information to the user based on the output data.

Abstract: A valve apparatus (10) comprises a housing (12) defining a flow path (14), a valve seat (42) located within the housing (12) around a periphery of the flow path (14), a carriage member (16) located within the housing (12), a cutting arrangement (28) mounted on the carriage member (16), and a valve member (32) mounted on the carriage member (16) via a connection assembly (34) which permits relative movement between the valve member (32) and the carriage member (16). The carriage member (16) is moveable from a first position towards a second position to drive the cutting arrangement (28) across the flow path (14) and to move the valve member (32) into a position in which relative movement between the valve member (32) and the carriage member (16) permits the valve member (32) to sealingly engage and disengage the valve seat (42) to control flow along the flow path (14).
Abstract: Disclosed is the redirection of air flow in a sub-plenum using a multi-directional plume that is attached to the bottom surface of an air-grate floor panel. The air-grate floor panel 102 has openings which allow redirected air to flow in an upward direction to cool computer equipment, including servers. The multi-directional plume has a series of vanes that are disposed in various different directions to deflect a flow of air conditioning air through a sub-plenum in a vertical direction to flow through openings in the air-grate floor panel. Since the multi-directional plume is capable of redirecting air from various different directions in the sub-plenum, the air-grate floor panels do not have to be repositioned to capture air flow from any particular direction.
Abstract: In an externally integrated steam generator type small modular reactor, a steam generator is arranged along the circumference of a reactor vessel cylindrical shell, and a steam drum is arranged along the circumference of the steam generator. The small modular reactor includes: a nuclear reactor including a hemispherical upper head, the reactor vessel cylindrical shell coupled to the upper head and extending downward from the upper head in a cylindrical shape, and a hemispherical lower head provided on a lower portion of the reactor vessel cylindrical shell, wherein a core is placed in the nuclear reactor; the steam generator surrounding all around the reactor vessel cylindrical shell and including a first penetration hole communicating with an inside of the nuclear reactor; and the steam drum surrounding the circumference of the steam generator and including a second penetration hole communicating with an inside of the steam generator.

Abstract: A thermal microring optical sensor is configured such that a portion of the optical resonator and its associated waveguide are encased within a cladding structure to minimize scattering losses along the waveguide and also provide improved evanescent coupling efficiency between the waveguide and the resonator. Functioning as a thermal sensor, incoming radiation modifies the temperature of the resonator, which changes its resonant frequency and, as a result, the percentage of light that it evanescently couples from the waveguide. The cladding structure also functions as a mechanical support for the resonator disk, eliminating the need for a pedestal to suspend the disk above the support substrate. Thermally-induced buckling of the optical waveguide is also reduced by encasing the susceptible portion of the waveguiding within the cladding structure.

Abstract: The invention relates to electrowinning of aluminum from cryolite-alumina melts, and can be used in the shunt design of a cathode assembly. In an aluminum electrolysis cell, cathode vertical metal shunts, are designed such that their top part is melted aluminum, and the bottom part is solid aluminum. Shunts are located in conduits made in a hearth slab lining which has a widening in the middle part which is wider than both parts of the shunts. The widening in the shunt conduit can be filled with a composite material, i.e. titanium diboride-carbon. The shunts can be designed as a tube, and the widening in the conduit and the space inside the tube can be filled with the composite material titanium diboride-carbon. The invention makes it possible to increase the electrical efficiency due to the absence of contact assemblies, reduced current loss, and achieving an effective current distribution and current shunting.

Abstract: A container lid with a finger entry section, a thumb entry section, a grasping section, and a mating section. The finger entry section includes a finger opening for receiving at least one finger of a hand. The thumb entry section includes a thumb opening for receiving a thumb of the hand. The grasping section is coupled to the finger entry section and the thumb entry section. The grasping section functions to grasp an item when compressed via the finger entry section and the thumb entry section and collectively prevent the finger(s) and the thumb from making direct contact with the item. The mating section is coupled to the finger entry section, the thumb entry section, and/or the grasping section and functions to mate the container lid with a container body.
