Abstract: A constraint graph for a candidate routing solution is created; each node in the graph represents a position of an end of a metal shape and each arc in the graph represents a design rule constraint between two of the nodes. A solution graph is computed, for at least a portion of the constraint graph, using a shape processing algorithm. The solution graph is checked for design rule violations to generate one or more violation graphs. A constraint window and a selection of one or more arcs for at least one of the violation graphs are generated. The candidate routing solution is revised, based on one or more violated design rules corresponding to at least one of the selected arcs within the constraint window. Optionally, an integrated circuit is fabricated in accordance with the revised solution.

Abstract: A sliding door includes a frame and a slow close assembly. The frame is positioned along at least a portion of the sliding door and includes a protrusion configured to slide along with the sliding door. The slow close assembly is repositionable between an outward position and a compressed position. The slow close assembly includes a slow close mechanism, a spring, and a soft close latch. The slow close mechanism is laterally positioned within the slow close assembly. The spring is positioned at an end of the slow close assembly and provides an outward force onto the slow close assembly in an outward direction substantially perpendicular to the lateral direction. The soft close latch is configured to engage the protrusion as the protrusion slides along with the sliding door. The spring biases the slow close assembly into the outward position when the latch is not interfaced with the protrusion.

Abstract: Embodiments for power generation include defining a power tile within a power distribution network having a grid of power rails, the power tile having logic gates, and applying an initial power grid pattern from a plurality of power grid patterns for the power tile such that initial power grid pattern relates to timing characteristics of the logic gates of the power tile. The power grid patterns each have a different number of connectors connecting one power rail to another power rail in the grid of power rails. A subsequent power grid pattern is selected from the power grid patterns for the power tile such that the subsequent power grid pattern meets a threshold condition for the timing characteristics of the logic gates of the power tile. The timing characteristics for the logic gates are determined based on a voltage drop associated with the subsequent power grid pattern.

Abstract: A seafood handling tool is provided that comprises a tong-like configuration with a first arm member and a second arm member in pivotal relationship to one another. The arm members are connected to one another along their proximal ends via a clevis, which extends from the first arm member and supports the second arm member from a pin joint. The clevis offsets the first and second arm member, while the pin joint allows the arm members to pivot relative to one another to accept larger or smaller seafood between the arm members along the distal ends. The distal ends of the arm members include elongated tines that extend from the inner surfaces thereof and towards one another. The tines engage an article of seafood while the user grips the proximal ends of the arm members, thereby separating the seafood from the handler.

Abstract: Provided are systems and methods for separating a purge gas recovered from a polyethylene product. The method includes recovering a polyethylene product containing one or more volatile hydrocarbons from a polymerization reactor and contacting the polyethylene product with a purge gas to remove at least a portion of the volatile hydrocarbons to produce a polymer product having a reduced concentration of volatile hydrocarbons and a purge gas product enriched in volatile hydrocarbons. The purge gas product is compressed to a pressure of 2,500 kPaa to 10,000 kPaa, and is then cooled and separated into at least a first product, a second product, and a third product. A portion of one or more of the first, second, or third products is then recycled as a purge gas, to the polymerization reactor, or to the purge gas product enriched in volatile hydrocarbons prior to compression, respectively.

Abstract: A method for olefin polymerization is provided. A feed stream comprising more than 0.1 ppm by volume of oxygen and 0.3 ppm by volume of water is passed through a first packed bed to selectively remove at least a portion of the oxygen. The feed stream is then passed through a second packed bed to selectively remove at least a portion of the water, providing a purified feed stream comprising less than 0.1 ppm by volume of oxygen and 0.3 ppm by volume of water. Both the first and second packed beds operate at a temperature of from about 0° C. to about 50° C. The purified feed stream is then passed to a polymerization reactor.

Abstract: A hockey stick is formed of a fiber-reinforced plastic blade integrally molded onto a tapered metal shank which mates with a rectangular tubular metal shaft or handle to form a four-plane lap joint which is bonded with a thermoplastic adhesive. The metal shank includes a longitudinally tapered recess which is filled by the molded plastic of the blade to form a virtually indestructible bond between blade and shank. The configuration provides great strength and precisely controllable flexibility with easy replaceability of the blade.
