Abstract: An insulating container having a base and a lid is provided. The lid may be rotatable about a hinge from a closed configuration to an open configuration and may be secured, via one or more latching devices, in the closed configuration. In some examples, the insulating container further includes a pull handle assembly with a telescopic three-stage arm configuration defined by a stowed configuration, a partially extended configuration, and a fully extended configuration. In other examples, the insulating container further includes a wheel assembly with a pair of wheels mounted with one or two axles, and further including a wheel grommet for absorbing shock and cushioning the axle. In still other examples, the insulating container further includes a drain plug assembly on the rear sidewall adjacent to the bottom portion of the base, the drain plug assembly comprising a main tube that cooperatively engages with an outer tube with a plurality of ratchet teeth that engage one or more ratchet keys on the main tube.

Abstract: Aspects of the present disclosure relate to obstruction detector assemblies, systems, and related methods for detecting obstructions along oil and gas equipment. In one implementation, an obstruction detector assembly includes a driver housing having an internal chamber and a plurality of fastener openings. The obstruction detector assembly includes a driver stem disposed at least partially in the internal chamber of the driver housing. The driver stem is movable partially out of the internal chamber of the driver housing. The obstruction detector assembly includes a driver head disposed outside of the driver housing and coupled to the driver stem. In one implementation, movement of the driver stem and the driver head is used to detect obstructions (such as a wireline) in a wellhead structure. In one implementation, movement of the driver stem and the driver head is used to detect obstructions (such as sand) in a valve.

Abstract: An articulated support fixture for a wind turbine blade includes a base frame with first and second bearing slide areas and first and second bearing blocks disposed to slide thereabout, each bearing block including a laterally oriented bearing. A fixture mount with a laterally oriented axle engages the laterally oriented bearings enabling the fixture mount to articulate about the lateral axle. The first and second bearing slide areas are configured to enable the first and second bearing blocks, together with the fixture mount, to slide along a generally longitudinal path, and to enable rotation of the fixture mount about a vertical axis as the first and second bearing blocks cooperatively slide upon the first and second bearing slide areas. A wind turbine blade interface is attached to the fixture mount, to enable engagement with, and support of, the wind turbine blade.

Abstract: Techniques for transforming input operands to reduce overhead for implementing addition operations in hardware are provided. In one aspect, a method for transforming input operands of an adder includes the steps of: receiving a bit array of the input operands; replacing a duplicate signal (e.g., a signal that occurs twice) for a given bit k in the bit array with a single signal at bit k+1; reducing a number of occurrences of the signal on adjacent bits of the input operand, wherein by way of the replacing and reducing a transformed bit array is formed; and providing the transformed bit array to the adder.

Abstract: Disclosed are a system and method for generating three-dimensional objects to represent files in a three-dimensional environment. A primary classifier classifies stored files into groups based on a first set of properties and generates three-dimensional mesh objects to represent each file. The mesh objects are the same within each group and distinguish the files from group to group. A secondary classifier further classifies each group of files into sub-groups based on a second set of properties and deforms the mesh objects in each sub-group in a particular manner to distinguish files from sub-group to sub-group. Additional classifiers modify the deformed mesh objects to further distinguish files within each sub-group (e.g., by varying the shape, texture, animation, etc.). Each three-dimensional object can then be embedded into a three-dimensional graphical user interface as a selection tool that provides visual cues regarding the contents of a particular file.

Abstract: Routability (or wiring congestion) in a VLSI chip is becoming increasingly important as chip complexity increases. Congestion has a significant impact on performance, yield, and chip area. The present invention targets the optimization of congestion early in technology independent synthesis prior to physical design. Instead of attempting to optimize the logic structure as well as the spatial placement of a circuit, we pose a more modest goal limiting such optimization to the scope of logic synthesis. That is, we propose an aggressive optimization approach that is cognizant of circuit structure during technology independent synthesis and produces more predictable implementations which give better routability and yield.

Abstract: A technology mapping method and device for mapping cost functions on directed acyclic graphs, using decoupled matching and covering and circumventing the memory explosion usually caused by this decoupling. Multiple matches are generated at the head of a wavefront process and embedded within the network. Covering is done at the tail of the wavefront to optimize one or more cost functions.
