  • Patent number: 8321835
    Abstract: A technique for generating good system decompositions is disclosed. The illustrative embodiment uses evolutionary programming in combination with a fitness function to generate a system decomposition that has a low degree of coupling and a high degree of coherence. A system is represented by an object-oriented specification using the Unified Modeling Language (UML); the UML specification is then represented by an eXtended Markup Language (XML) document, and the contents of the document are transformed into a nested-list data structure that resembles source code in a functional programming language such as Common LISP. The nested-list data structure and an appropriate fitness function are input to an evolutionary programming engine that operates on the nested-list data structure as though it were a source code program, and generates an output source code program. A system decomposition is then derived from the output source code program.

  • Patent number: 7129887
    Abstract: In an exemplary embodiment, an augmented reality system for traffic control combines data from a plurality of sensors to display, in real time, information about traffic control objects, such as airplanes. The sensors collect data, such as infrared, ultraviolet, and acoustic data. The collected data is weather-independent due to the combination of different sensors. The traffic control objects and their associated data are then displayed visually to the controller regardless of external viewing conditions. The system also responds to the controller's physical gestures or voice commands to select a particular traffic control object for close-up observation or to open a communication channel with the particular traffic control object.

  • Patent number: 6720953
    Abstract: A computer display system connectable to a computer system includes a computer-driven display screen displaying information from the computer system. A manual display screen mounted to the computer-driven display screen displays information provided by a human operator. The computer-driven display screen is viewable from a line-of-sight in a first mode of operation, and the manual display screen is viewable from the line-of-sight in a second mode of operation.
