Patent number: 10678649Abstract: User interactions with a database storage system allow creation of virtual databases based on point-in-time copies associated with a source database. Multiple point-in-time copies are obtained for each source database. A point-in-time copy retrieves data changed in the source database since the retrieval of a previous point-in-time copy. A virtual database (VDB) is created by creating a set of files in the data storage system and mounting the files on a database server allowing the database server to access the files. User interactions allow the user to specify the source database, a point in time associated with the source database and a destination server to create the virtual database. User input can specify other attributes associated with the virtual database including the file paths, database parameters etc. The user can specify schedules of various actions, including making and retention of point-in-time copies.Type: GrantFiled: October 2, 2017Date of Patent: June 9, 2020Assignee: Delphix CorporationInventors: Jedidiah Yueh, Xavier David Luiz, Yan Wang, Alok Srivastava

Patent number: 10563980Abstract: A method and apparatus utilizing a high-precision GNSS receiver, an EDM, and an optical camera in combination for making accurate measurements of multiple remote points. The accurate measurement of a plurality of remote points is facilitated by integrating a high-precision GNSS receiver, an EDM and an optical camera such that their combined physical location and orientation can be measured and known, and allowing for a single calibration thereof. The integration of the high-precision GNSS receiver, an EDM, and an optical camera may take various forms such as a single, integrated device, or individual devices assembled together on a surveying pole, for example. The integrated device may also include one or more sensors such as an inclination sensor and an inertial measurement unit.Type: GrantFiled: December 23, 2016Date of Patent: February 18, 2020Assignee: Topcon Positioning Systems, Inc.Inventors: Leonid Valerianovich Edelman, Jason Hallett, Alok Srivastava

Patent number: 9969764Abstract: This invention is related to nucleic acid chemistry and describes novel 1,2-dithiolane functionalized nucleoside phosphoramidites (1, Chart 1) and corresponding solid supports (2, Chart 1). In addition to these derivatives, 1,2-dithiolane moiety can also be functionalized to at the various positions of the nucleobase and sugar part as shown in Schemes 1 to 8. The nucleosides of our invention carry a primary hydroxyl for DMTr (4,4?-dimethoxytrityl) function for chain elongation. Furthermore, the phosphoramidite function is attached at the 3?-hydroxyl of the nucleoside. This allows oligonucleotide chain extension under standard DNA and RNA synthesis chemistry conditions and techniques, thus leading to high quality oligonucleotides. These derivatives are useful for introduction of reactive thiol groups either at 3?- or 5?-end of the oligonucleotides on the solid supports such as gold, silver and quantum dots.Type: GrantFiled: April 19, 2016Date of Patent: May 15, 2018Inventors: Suresh C Srivastava, Santhosh K Thatikonda, Sant K Srivastav, Praveen K.

Patent number: 9441002Abstract: The thiol modified oligonucleotides have vast number of applications in the field of nucleic acid chemistry. The conjugates generated by mono thiol groups are unstable at higher temperature, in high salt concentration buffers and in presence other thiols. There is strong need to develop a novel thiol modifier probes that can generate multiple thiol groups. Described herein are efficient processes and compounds, dithiolane phosphoramidites derivative and dithiolane succinyl supports. The advantage of our cyclic disulfide thiol modifier is multifold a) each incorporation introduces two thiol groups; b) it can be introduced at any desired site of oligonucleotides; c) The symmetrical branching nature of the spacer in the linker arm of dithiolane allows for clean oligo synthesis, where cleavage of the linker arm and thereby of loss of oligo chain is prevented.Type: GrantFiled: October 28, 2013Date of Patent: September 13, 2016Assignee: ChemGenes CorporationInventors: Suresh C.
