Abstract: A method includes receiving a query that is unstructured for a plurality databases; determining a service requirement fulfilled by the databases from the terms of the query; determining, for each of the databases, a service requirement score for the database; selecting one of the databases based on the service requirement scores; determining, from the query, parameter values for the service requirement; providing the parameter values for a search operation for the selected database and receiving database search results responsive to the parameter values and the search operation; determining, from the database search results, a search constraint for the search query; revising the search query to include the constraint and providing the revised search query to a search engine; and providing search results identifying resources that the search engine determined to be responsive to the revised query.

Abstract: Methods and systems for adapting existing service provider servers to support two-factor authentication by leveraging an authentication server, which may be operated by a third party. Where a user desires to access content or services offered by a service provider server, the user may employ a client agent (for example, a web browser) in order to authenticate with the service provider server. Service provider server can redirect client agent to an authentication server to process at least a second factor or derived credential.

Abstract: The present invention relates to a computer implemented system for transferring data over a master driven TDD/TDMA based wireless network operating with minimum delay in end-to-end transmission by achieving optimum time slot utilization by minimizing the number of baseband packets created for each Link layer packet, where each baseband packet of is a size corresponding to one of a permitted set of capacities ‘C1, C2, . . . Cn’. The system also optimizes sharing of bandwidth, higher link utilization and low baseband packet transmission queue occupancy by adaptive scheduling of the transmission of the baseband packets in the queues. The invention also provides a method and computer program product for the above system.
