Abstract: A method of searching paths that are susceptible to electrostatic discharge (ESD) at the beginning of an integrated circuit (IC) design is disclosed that includes a circuit spreading out algorithm, a matrix closure algorithm, and a supernode algorithm. The found paths are required to satisfy conditions including that (a) they are connected from a gate of a transistor to a source or a drain thereof, and (b) the head node and the tail node of each path are pins of a top level of the IC. ?1/0/1 matrix multiplication is employed by both the circuit spreading out algorithm and the matrix closure algorithm so as to obtain a result of node connections after a plurality of matrix self-multiplications.

Abstract: A yarn carrier (30) for presenting a selected yarn (16) to a pair of gripper jaws (26,28). The yarn carrier (30) includes a yarn guide passageway (14) defining a path along which the selected yarn (16) is longitudinally guided. The passageway (14) has a yarn inlet end, a yarn outlet end and adjacent to the yarn outlet end yarn guides (32) to constrain the tail of the yarn (YT) against lateral deflection in a longitudinal direction of the yarn carrier (30). The yarn guides (32) are depressible on contact with open gripper jaws (26,28) to enable the gripper jaws (26,28) to grip the yarn tail (YT).

Abstract: A method of identifying a compound with efficacy in the treatment of chronic inflammatory disease by testing the compound for an ability to selectively inhibit the ability of Tck cells to induce pro-inflammatory cytokine release from a monocyte is disclosed. The method includes pre-incubatin Tck cells with a compound to be tested, optionally resuspending the Tck cells in the absence of the test compound, co-culturing the Tck cells with monocytes, and assaying for the production of pro-inflammatory cytokines by the monocytes. The Tck cells are produced by incubating a population of T cells with one or more cytokines or the Tck cells are isolated from synovial tissue. The Tck cells have not been contacted with an anti-CD3 antibody. The ability to selectively inhibit cytokine release indicates that the compound has efficacy in the treatment of chronic inflammatory disease.

Abstract: A device for directly measuring a person's respiratory exchange ratio (RER) utilizes a Zn-air battery cell and a constant current load circuit as an O2 pump capable of drawing oxygen from expired air. A thermistor located in the flow path forms a leg of a bridge circuit whose output is proportional to oxygen concentration in the expired air and, therefore, to oxygen uptake. The thermistor flowmeter circuit utilizes the thermal conductivity differences between O2 and CO2 to provide a measure at the relative ratio of the two gases present.

Abstract: A method and apparatus is employed to create a mixture having a desired composition. A raw material is separated in a pair of density separators into constituent parts. Those parts are then recombined in a desired fashion using a pair of splitters to create an intermediate mixture and delivered to a third density separator. The third density separator processes the intermediate mixture to create a final mixture having the desired composition.

Abstract: A single-carriage reversing train positioning system which includes an extending spike-type car engaging member for engaging and moving one or more railcars. An extending chuck assembly may be provided with the ability to operate gates in bottom-discharging railcars. The system uses a single self-propelled carriage with an on-board carriage drive system that includes a drive motor which operates the car along a fixed chain situated along a guideway. A generally horizontally disposed, laterally extendable pin car-engaging assembly is mounted on the car-moving carriage for aligning with and engaging a hook loop on a railcar for moving the car. A gate-operating assembly which includes a laterally extendable chuck system which aligns with, engages and rotates gate-operating capstans on bottom discharging railcars may also be provided.

Abstract: A method and apparatus for designing low-order linear-phase IIR filters is disclosed. Given an FIR filter, the method utilizes a new Krylov subspace projection method, called the rational Arnoldi method with adaptive orders, to synthesize an approximated IIR filter with small orders. The method is efficient in terms of computational complexity. The synthesized IIR filter can truly reflect essential dynamical features of the original FIR filter and indeed satisfies the design specifications. In particular, the linear-phase property is stilled remained in the passband.

An effective length of each pivot arm may be adjusted and locked in adjusted position.

Abstract: A lightweight plastic cover for an electric handhole or pullbox having a plurality of vertical channels in a circular array at a radius about halfway from the center to the circumference. The channels allow the cover to bend when a large weight is applied and to rebound when the weight is removed. The cover may also have a second circle of vertical channels for strength nearer the center and horizontal channels crossing the center for added strength. The cover has a metal plate attached in the center for finding the cover with a metal detector and may also have a GPS device for locating it. The electric handhole or pullbox may have an open bottom portion with a ledge around the circumference for helping to set and maintain the electric handhole or pullbox at a desired depth. The cover may have extendable handles for ease of holding.
