  • Patent number: 7599957
    Abstract: A metadata database adaptor for use with a surveillance and/or sensor system is capable of adapting metadata messages of varying formats according to needs of metadata databases. In other aspects, a metadata data model template can allow a user to define a data definition that is used to map user defined data with the metadata data model template to form XML data schema. Template mapping knowledge can then be applied for fast XML data schema to non-XML database schema generation without translation processing. In yet other aspects, an application domain template can allow a user to define a query definition that can then be processed with a mapping of the application domain template to translate Xpath, Xquery, or others to a database query.

  • Publication number: 20080198159
    Abstract: The surveillance visualization system extracts information from plural cameras to generate a graphical representation of a scene, with stationary entities such as buildings and trees represented by graphical model and with moving entities such as cars and people represented by separate dynamic objects that can be coded to selectively reveal or block the identity of the entity for privacy protection. A power lens tool allows users to specify and retrieve results of data mining operations applied to a metadata store linked with objects in the scene. A distributed model is presented where a grid or matrix is used to define data mining conditions and to present the results in a variety of different formats. The system supports use by multiple persons who can share metadata and data mining queries with one another.

  • Patent number: 7237260
    Abstract: Distributed modules in a network dynamically select communication protocols to communicate in a secure or firewall-protected network. Applications register with a lookup service. The lookup service maintains a lookup table including registration information for multiple applications. Registration information may include, but is not limited to, IP address, firewall restrictions, tunnel protocol, port information, and proxy queue capabilities. An application seeking to communicate acquires the registration information for a desired recipient from the lookup table. The application uses the registration information to select communication protocols necessary to communicate with the recipient.

  • Patent number: 7167899
    Abstract: The Web customer contact system is based on distributed execution of service logic programs that can be dynamically altered based on changing business needs. The distributed and dynamic program modification makes the Web customer contact system scalable and customization to the most demanding business operation needs. For example, existing workflow based GUI programming tool, which only support centralized specification, down load and execution of routing rules for incoming calls in a contact center. The new system WCC system can allow user to specify a set of service logic program (SLP) can be dynamically attached to any distributed “addressable entities” in the WCC system. The addressable entities can be a user, an agent, an email box, a work group, IVR system, or a department web site. The addressable entities can be located anywhere that can be reached by internet address (an URL or other types of identities).
