  • Patent number: 9081819
    Abstract: Techniques are provided for using bonds, which reflect relationships between items, to facilitate searches against the items. The degree of separation between any two given searchable items is based on the minimum number of bonds that have to be traversed to arrive at one of the two searchable items when starting at the other of the two searchable items. The bonds are used to respond to a search request, performing a search relative to a particular searchable item. For example, the search may involve only those searchable items that are within a particular degree of separation of the particular searchable item. As another example, the search may involve determining the order in which searchable items are compared against search criteria of the search request based on the degree of separation of the searchable items from the particular searchable item.

  • Patent number: 8966321
    Abstract: A test configuration resource manager and a method of managing test configuration resources in a network test system. A computer readable storage medium may store instructions that, when executed, cause a computing device to receive a user input identifying a portion of a first test configuration, store the identified portion of the first test configuration as a test configuration resource in a library of test configuration resources, receive a user input identifying a stored test configuration resource, retrieve the identified stored test configuration resource, and incorporate the retrieved test configuration resource into a second test configuration. The library of test configuration resources may include one or more of port resources, protocol resources, and traffic resources.

  • Patent number: 8949186
    Abstract: 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.

  • Patent number: 8903846
    Abstract: Techniques used in a relational database system for defining subclasses of built-in classes and thereby achieving columns in database tables which contain polymorphic objects of the built-in classes. The methods for the subclasses are contained in named packages. A table in the database system's schema relates the package name to a storage location managed by the relational database system that contains the compiled code for the package. When a method from the package is invoked, a dynamic linker uses the name and the table to locate the compiled code and then executes the compiled code. One thing that can be done with subclasses is to use a database system to automatically connect a Web user with a server of streaming data. The connection thus established is made by the server of streaming data to the Web user and thus bypasses the database system.

  • Patent number: 8847639
    Abstract: A waveform generator for providing an analog output signal to a target device includes a look-up-table (LUT) that stores a plurality of binary address values and a digital-to-analog converter (DAC) that generates the analog output signal. The waveform generator receives an input trigger signal from the target device when the target device is ready to receive the analog output signal. The waveform generator generates a synchronized input trigger signal and aligns the analog output signal with the synchronized input trigger signal by reloading the LUT with a binary address value of zero.

  • Publication number: 20140142253
    Abstract: 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.
