    摘要： A method of and service for optimizing an integrated circuit design to improve manufacturing yield. The invention uses manufacturing data and algorithms to identify areas with high probability of failures, i.e. critical areas. The invention further changes the layout of the circuit design to reduce critical area thereby reducing the probability of a fault occurring during manufacturing. Methods of identifying critical area include common run, geometry mapping, and Voronoi diagrams. Optimization includes but is not limited to incremental movement and adjustment of shape dimensions until optimization objectives are achieved and critical area is reduced.

    摘要： A method for providing redundancy in a daisy chain local area network employing Category 5 cabling for connecting network devices uses the normally unused twisted wire pairs in the single Cat 5 cable connecting adjacent network devices. The method includes forming in each network device a passive signal path connecting pins of an upstream port associated with the normally unused twisted wire pairs of the Cat 5 cable to pins of a downstream port associated with the normally unused twisted wire pairs of the Cat 5 cable, forming loop back connections at the terminal network devices where the loop back connections connect the normally used twisted wire pairs to the normally unused twisted wire pairs of the Cat 5 cable connected to the terminal network devices, and implementing a Spanning Tree Protocol in each of the network devices for defining an active signal path through the local area network.

    摘要： The invention provides a method of modifying a hierarchical integrated circuit layout wherein the locations of hierarchical layout elements are represented with variables and formulae using these variables, which produces a formula-based hierarchical layout. These variables are constrained to be integers. The invention provides for a method for guiding the modification of the layout through an objective function defined on the same variables as the formula-based hierarchical layout. The invention simplifies the formula-based hierarchical layout by substituting constants for some of the variables, such that each of the formulae are reduced to expressions involving no more than two remaining variables. This produces a simplified layout equation and a simplified objective function. This also produces a partial solution to the hierarchical layout modification made up of the values selected for the constants.

    摘要： A two-stage method of recovering the noble metal content of a mixture of noble metals, for example, platinum, palladium, and rhodium, this mixture being, for example, comprises on or throughout a pellet or on or throughout a ceramic monolith of a spent catalyst, the method comprising first reductive chlorination at an elevated temperature by a gaseous chlorinating agent in the presence of a reducing agent (preferably the reducing agents sulfur dioxide and carbon monoxide in stages); minimizing the amount of aluminum trichloride formed from either washcoat or underlying ceramic chlorination, and separating the aluminum trichloride or other washcoat chlorides from the products of chlorination of the noble metals, as by sublimation of the former in a reducing atmosphere at a temperature below the vaporization temperatures of the latter, thereby recovering the noble metal chlorides in a concentrated form. As a second stage, temperature is further increased in an atmosphere of chlorine alone to volatilize rhodium trichloride for collection seperately from the palladium and platinum chlorides volatilized previously in the first-stage reductive chlorination.

    摘要： A technique for controlling the gain of a photomultiplier tube (PMT) 20. A voltage divider (resistors 45-49 in FIG. 1 and zener diodes 60-65 in FIG. 3) is used to control the potentials on dynodes 5, 7, and 9 of PMT 20. Transistor switches 53 and 58 provide the control of the voltage divider in FIG. 1 and photodiodes 66, 67 and 70 provide the control in FIG. 3. The gain control of PMT 20 is in the range from 100% to less than 0.001% (100,000 to 1).
