Abstract: Method and system for the integrated securing and managing of virtual machines and virtual appliances are presented. Sealing the virtual appliance at the computer of a sender, verifying authenticity of the sender at a recipient computer and managing the execution of the VA are performed in a seamless fashion.

Abstract: A method and apparatus for defining and validating feature policies in an execution system, such as a communication system. The method includes entering user policies described in a straightforward manner (e.g. using a Web browser and user-understandable language) in such a way that they can be translated into a formal executable language. The user policies are then (translated into an executable feature language such as the IETE's CPL. The user is then either compelled or provided with an option to validate the overall feature set before the overall feature is uploaded to the execution system. If validation is selected, the features are translated from CPL into another format, such as FIAT, from which it is possible to detect common feature specification errors. That FIAT detected errors are then analyzed in a manner that is aware of the expectations and common errors of native users, and interpreted to determine possible errors as errors that are common to naïve users.

Abstract: A personal digital assistant (PDA) enabled telephony system is provided comprising a telephone set having a communication port and a personal digital assistant. The personal assistant includes a user interface for displaying telephony functions to a user; a detector for detecting a selected telephony function; a telephony application for determining a call command based on the selected telephony function; and a communicator for communicating said call command to the communication port. In response to receiving the call command, the telephone set executes the selected telephony function.

Abstract: The present invention is directed at hybrid network configuration, comprising a plurality of application platforms for sending and receiving at least one of voice and data in accordance with a first predetermined protocol, a voice/data network for routing the voice and data between the plurality of application platforms in accordance with a second predetermined protocol, and at least one network portal for providing the plurality of application platforms access to the voice/data network using the first and second predetermined protocols.

Abstract: A teaching system comprising student and teacher computer stations which are serially connected in a closed loop circuit. Each student computer and the teacher station comprises a computer device having an associated video monitor connectable thereto via an interface unit. A teacher controller device is provided at the teacher control station and has an output connected to the interface units to transmit an information network signal thereto to condition the interface units to place its associated student computer station to a preselected mode. A keyboard is associated with the controller device at the teacher control station for selecting the mode. A visual display on the controller indicates the selected mode to the teacher.
