Abstract: Multiple verification cases consisting of code sequence and initial context, and suitable for electrical verification testing of a device, are generated from a single verification case by permuting, or changing, the code sequence, by either permuting the initial context of the code sequence or permuting the code sequence itself. The code sequence is an array of computer instructions to be executed by a computer and the initial context of the code sequence refers to the environment in which the code sequence is to be run.

Abstract: A combinatorial method for discovering or optimizing materials is disclosed. The method uses solution-based components that are mixed and dispensed into regions on a substrate for drying and/or heat-treating. The drying and/or heat-treating produces materials that can be tested for a desired property.

Abstract: The operating-point differentiated test results are obtained by running a code sequence on the device at a first operating point to generate predicted results and then running the same code sequence on the device at a second operating point defined by changing an electrical parameter of the first operating point to generate actual results. Any differences that might exist between the predicted and actual results are due to the changed operating point of the device.

Abstract: The inventions disclosed herein are new complexes and catalysts comprising metal-ligand complexes or compositions of metal precursors and ligands (and optionally activators) that catalyze polymerization and copolymerization reactions, particularly with monomers that are olefins, diolefins or acetylenically unsaturated. These compositions can also polymerize monomers that have polar functionalities in homopolymerizations or copolymerizations. Also, diolefins in combination with ethylene or &agr;-olefins or 1,1-disubstituted olefins may be co-polymerized. The new catalyst compositions can be prepared by combining a metal precursor with a suitable ligand and, optionally, an activator or combination of activators. The main feature of this invention is the use of new metal ligand complexes to provide the active polymerization catalysts.

Abstract: The present invention relates to a process of conducting research using combinatorial techniques wherein metal-ligand compositions are synthesized and screened for reactivity in reactions of interest, particularly metal-ligand compounds which are suitable for use as catalysts. In the process, an array of different metal-ligand compositions is prepared by delivering a dissolved, soluble metal precursor and a metal-binding ligand to each reaction vessel or well in the array, where they may optionally be combined with an activator and/or other additives. The resulting metal-ligand composition in each vessel is then screened for reactivity in a chemical reaction of interest, particularly for catalytic activity in a polymerization reaction.

Abstract: A metrological instrument for measuring surface characteristics such as surface form of a component (300). The instrument includes a slideway (32) to cause relative movement between a surface sensing probe (84) and the component which allows the probe to traverse a surface of the component. A probe carriage (80) supports the probe to allow the probe to move as a body in a measurement direction relative to the carriage so as to follow a surface being sensed. An optical sensor (82) provides a signal indicative of the displacement of the probe relative to the probe carriage. A controller (83) acts in response to a signal from the optical sensor, to move the probe carriage so as to maintain the probe in an operational range. A further sensor (11) measures measurement of displacement of the probe in the measurement direction as it follows a surface during use of the instrument.
