  • Patent number: 9858575
    Abstract: Methods, computer-readable media and devices for calculating fraud scores for pending payment transactions are disclosed. A method includes a processor receiving a request for a fraud score. The request comprises a notification of a pending payment transaction that is associated with a credit card of a user and associated with a first location. The processor then detects a location of a device associated with the user, calculates a fraud score based upon the location of the device and the first location, and sends a response comprising the fraud score that is calculated.
    Type: Grant

  • Patent number: 7580799
    Abstract: Steric features inherent in the three dimensional disposition of atoms in molecules can be represented as multiplets using a defined set of steric descriptors. The resulting multiplets can be encoded in a compressed form of bitstring known as a bitmap. Such bitmaps can be generated in compressed form and used to compare individual conformers or ensembles of conformers of molecules to each other without decompression. Such comparisons are useful in molecular similarity analysis, in molecular diversity analysis, in database searching, and in conformational analysis.

  • Publication number: 20070143030
    Abstract: A method is disclosed that overcomes the problem in the prior art of requiring the use of a template or base molecule in order to compare the three dimensional configurations of molecules. The disclosed method teaches that the requirement for a template can be eliminated by handling the components of configuration—conformation versus rotation and translation in three-dimensional space—separately. The internal coordinate (torsional) space is explored first using a multi-objective genetic algorithm to minimize strain while maximizing steric and pharmacophoric concordance. Optimal overlays in Cartesian space are then obtained by applying a 3D hypermolecule construction method that makes use of linear assignment to identify optimal feature correspondences between ligands.

  • Patent number: 6875076
    Abstract: An apparatus and method is provided for polishing work pieces such as semiconductor wafers. The apparatus includes a variable number of independent heads 20, platens 32 and polishing units 18. This polishing apparatus belongs to a group of polishing machines with wafers attached to the same heads 20 through all polishing steps without undesirable reloading from one head 20 to another between polishing steps. Each independent head 20 is automatically coupled to and decoupled from any of the polishing units 18 to optimize throughput and provide flexibility in accommodating different polishing processes. A head transfer subsystem 22 provides an independent means of transfer for each head 20, thus an infinite number of contemporaneous or overlapping polishing cycles can be completed on multiple wafers resulting in maximum processing throughput.

  • Patent number: 6494775
    Abstract: A lightweight, carrier for wafer-like objects, including semiconductor wafers, is provided. The carrier may be used to secure and position a wafer during various polishing processes. The improved design of the lightweight carrier includes a relatively high number of ribs and an annular flange having an annular protrusion to provide uniform load onto the wafer during polishing operations. The relatively lower weight of the carrier facilitate manual loading and unloading of it (the carrier) into and from the polishing machine.
