Patent number: 8793655Abstract: Encoding a new version of a data module includes constructing a delta data module having data for providing the new version of the data module. The delta data module may indicate an encoding for copying data at an offset from one of a number of pointers into different versions of the data module. Decoding a delta data module to provide a new version of a data module includes copying, to the new version of the data module, data relative to a target pointer when an encoding in the delta data module indicates a matching pattern relative to the target pointer, and copying, to the new version of the data module, data relative to at least one other pointer when an encoding in the delta data module indicates a matching pattern relative to the at least one other pointer.Type: GrantFiled: January 30, 2013Date of Patent: July 29, 2014Assignee: Microsoft CorporationInventors: Alexander Petrov, Thomas McGuire, Michael Sliger

Publication number: 20130328882Abstract: Systems, methods, and computer program products for named area generation are disclosed. In some implementations, documents are processed to uncover pairs of text strings and geographical regions (e.g., a collection of simple convex polygons).

Publication number: 20110034715Abstract: The present invention concerns cyclopentadienylphosphazene complexes (CpPN complexes) of the metals of the third and fourth group and of the lanthanoids with the exception of lutetium. The complexes according to the present invention are isolobal and isoelectronic to [(CpSiN)TiR2] complexes. Exactly one CpPN unit is present in the complexes according to the present invention. In all complexes according to the present invention, the cyclopentadienyl unit of CpPN represents a monodentate, anionic ligand of the metal atom. Furthermore, the metal atom is bound to further anionic ligands. In a preferred embodiment, both the cyclopentadienyl unit and the nitrogen atom are bound within CpPN to the metal atom, so that CpPN then represents a bidentate ligand. Complexes according to the present invention, in which CpN represents a bidentate ligand, are CpPN-constrained geometry complexes (CpPN-CGC). Furthermore, methods are provided for the in situ production of the complexes according to the present invention.Type: ApplicationFiled: November 25, 2008Publication date: February 10, 2011Inventors: Jörg Sundermeyer, Konstantin Rufanov, Alexander Petrov, Michael Elfferding, Manuel Winkenstette

Publication number: 20110034713Abstract: The present invention describes homoleptic, ortho-metalated, chelate-stabilized benzylamine complexes of the rare-earth metals. The rare-earth metals are selected from Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu. In the complexes according to the present invention, at least one benzylic proton of the benzylamine ligand is replaced by an alkyl or aryl group. Such complexes are preferred in which both benzylic protons of the benzylamine ligand are replaced by an alkyl- or aryl group. The complexes according to the present invention are produced by reaction of chelate-stabilized rare-earth metal halides with ortho-lithiated aryl ligands at room temperature under inert gas atmosphere. The complexes according to the present invention are thermally stable and suitable for being used as catalysts for the hydroamination of olefins.Type: ApplicationFiled: November 25, 2008Publication date: February 10, 2011Inventors: Jörg Sundermeyer, Alexander Petrov, Oliver Thomas

Patent number: 7600225Abstract: A system and method for providing file data, such as a set of files for updating a computer system, in a self-contained package, in which the package size is significantly reduced via delta compression. A build mechanism examines files to be distributed, and generates a self-contained package containing files and deltas. To this end, a directed graph is built from the sizes of the various base file and delta file possibilities, and a minimum spanning tree computation selects the files that result in the smallest package. A base file may have multiple deltas applied to synthesize multiple files, and any base file may itself have been previously synthesized from another base file and a delta. A client extraction mechanism, optionally provided with the package, works with the contents of the package as directed by a manifest to synthesize target files from the base files and the contained deltas.Type: GrantFiled: July 21, 2003Date of Patent: October 6, 2009Assignee: Microsoft CorporationInventors: Michael Sliger, Thomas McGuire, Manojkumar Shende, Alexander Petrov
