  • Patent number: 7865517
    Abstract: A method in a computer system for retrieving data from one of multiple copies of the data is provided, referred to as the data management system. The data management system receives a request identifying at least one data object to be accessed. Then, the data management system queries a metabase to locate data copies that contain the identified at least one data object, wherein the data copies are created from similar source data, and wherein for each data copy the metabase contains an indication of the availability of the copy relative to other copies. Next, the data management system determines one of the located data copies to use to access the identified at least one data object, wherein the determination is made based on the indicated availability contained in the metabase for each of the located data copies. Then, the data management system accesses the identified at least one data object using the determined one of the located data copies.

  • Publication number: 20100318606
    Abstract: A distributed system for distributing conferencing data such as video, audio, and other conference data. The distributed system includes a conference data dispatch system, multiple conference participant computing systems, and a network distribution path through which conference data may be distributed from the conference data dispatch system to the various conference participant computing systems. The conference data is segmented. Each segment is encoded to be suitable to a particular class of participant computing systems. The encoded segments may be cached in an intermediary computing system to thereby avoid a strict unicast model for distributing conference data.

  • Patent number: 7844573
    Abstract: A system and method for operating a storage library. The system comprises a management server, a media agent connected to the management server, a library connected to the media agent and a database connected to the management server. The management server controls the media agent to monitor for the addition or removal of a piece of media in the library. When the media agent determines that the piece of media has been added to the library or removed from the library, the media agent causes the library to read a media label stored as data on the piece of media, the media label including an identifier identifying the piece of media. When a backup or restore is performed, the system checks the media label to ensure that the correct media is being used. Inventory procedures are disclosed.

  • Publication number: 20100266443
    Abstract: A Pd—Ag alloy system that utilizes internal oxidation by including a base metal addition of only Ga is provided. The Pd—Ag—Ga alloy is particularly well-suited for use in porcelain-fused-to-metal (PFM) applications because the alloy does not form a dark oxide upon heating. The high oxygen potential of the material ensures the development of a tenacious chemical bond with the porcelain when used in PFM applications. Moreover, the addition of gallium lowers the liquidus temperature of the alloy to improve castability and strengthens the alloy significantly.

  • Publication number: 20100218120
    Abstract: Managing a web based conference. The web based conference includes one or more presenters connected through a network to one or more conference attendees. The presenters control data sent to the attendees. User input is received at a presenter computing system from a presenter indicating that a message should be sent to a number of computing systems being used by attendees. In response to receiving the user input at the presenter computing system, a message is sent to the of computing systems. One or more acknowledgment messages are received from at least a portion of the plurality of computing systems. Based on the one or more acknowledgement messages, a metric is generated for the number of recipients that received the message. The metric is displayed to the presenter.

  • Patent number: 7673550
    Abstract: A formable fiber-reinforced composite having an inner core of fiber-reinforced composite surrounded by a sheath of fiber-reinforced composite material. The inner core of fiber-reinforced composite has a plurality of longitudinally extending fibers disposed in a resin matrix material and formed in the shape of a rod. The sheath has woven or braided fibers impregnated with a resin matrix material in the form of a sleeve. A method of manufacturing the formable fiber-reinforced composite material is provided. The longitudinally extending fibers in resin matrix material is cured to provide a solid rod. A sheath is placed around the rod. The rod with sheath is treated (e.g., heat, chemical solution, or both) to remove the resin matrix material. Thereafter, the rod and sheath are impregnated with a resin matrix material. The resin is left uncured or partially cured to provide a formable fiber-reinforced composite material. The formable material may be flattened.

  • Publication number: 20100038807
    Abstract: Solid free form fabrication techniques can be utilized indirectly to manufacture substrates, dies, models, near-net shapes, shells, and wax-ups that are then used in the manufacture of dental articles. Digital light processing is the most preferred indirect method for the production of substrates. After the substrates are produced, various coating or deposition techniques such as gel casting, slip casting, slurry casting, pressure infiltration, dipping, colloidal spray deposition or electrophoretic deposition are used to manufacture the dental article.
