Abstract: A method for generating and maintaining hierarchical tags with community-based ratings is provided. Tags for media streams are organized into a hierarchical format. Users may select tags from the hierarchical tag database that describes a particular multimedia content. If the user is unable to locate a desired tag, the user may submit a new tag. Upon submission of the new tag, a librarian approves the tag before storing and placing the tag in the hierarchical tag database. Users are also able to rate the quality of the association between the tag and the multimedia content. If a tag is rated low, the tag may be removed from the hierarchical tag database. If the tag is rated highly, display of the tag in a list of tags becomes more prominent.

Abstract: Techniques disclosed herein provide a user experience with virtual reality content and user-selected, real world objects. An exemplary technique involves receiving input selecting a subset of the real world objects in a selection view. The subset of the real world objects is selected for inclusion in the user experience. The technique further involves identifying virtual reality content for inclusion in the user experience. The technique provides the user experience by combining a live view of the user's real world environment with the virtual reality content. The real world objects in the live view that are in the subset selected by the user are visible in the user experience. The real world objects in the live view that are not in the subset selected by the user are replaced with virtual reality content.

A bid automation engine allows a user or business entity to specify a number of rules for bidding on keywords used in Internet advertising campaigns. The bid automation engine may be part of, or interface with, a web analytics tool and/or a bid management system to provide user-defined strategies for bidding on keywords. Accordingly, a user or business entity may set up a customized bidding strategy for keywords by building sets of bidding rules.

Abstract: A method is described of mixing fluid materials, including solids and gases. The materials to be mixed are introduced between two cylindrical rotors mounted in parallel on a motorized shaft. The rotors have arrays of cavities on their cylindrical surfaces and rotate within close proximity to the interior of a cylindrical shell. Passage of the fluid between the rotating rotors and the interior surface of the cylindrical shell causes cavitation, which mixes the materials. The mixture is passed to outlets on the far sides of the rotors from the inlet. Apparatus is described for extending the flow path of the materials and thus increasing exposure to the cavitation process.

Abstract: The present invention provides a method of indirectly determining the optical signal-noise ratio of an optical fibre communications link. In a test environment, the relationship between OSNR and pre-FEC BER (forward error-corrected bit error rate) is determined for a particular type of optical transponder. When a transponder of that type is connected to an optical communications link then the pre-FEC BER can be measured and the OSNR inferred from the pre-determined OSNR-BER relationship. The OSNR value can then be used to select a transponder modulation format or other transmission parameters.

The user interface interactions and the application results are analyzed. Events, metrics, and relationships are determined based on the analysis. In some cases, additional data (such as historical interactions and results, system environment data, or system configuration data) are received and analyzed, and the determined relationships are further based on the additional data.

Abstract: Heavy fluids are made from calcium bromide and at least one hydrogen bond donor such as a low molecular weight polyol or an organic acid. The combination of a hydrogen bond donor and calcium bromide as a hydrogen bond acceptor in an appropriate molar ratio forms a higher density clear completion fluid at a low temperature not otherwise obtainable with heavy aqueous solutions of calcium bromide such as are used in oilfield wells. A method of making the fluid comprises mixing calcium bromide with the polyol(s) in the presence of water and then reducing the water content, thus forming a heavy fluid. A crystallization inhibitor such as nitrilitriacetamide or a particulate silicate is included in the formulation. When the heavy fluid “freezes,” its physical form is somewhat amorphous and pumpable rather than crystalline. The heavy fluid is useful as a drilling fluid as well as a completion fluid and for other purposes in oil recovery processes where extreme density is beneficial.
