The method comprises the steps of: partitioning the predetermined area into cells (100); determining a starting cell for the entity (200); initiating a scan of a number of the cells from the starting cell and determining the content of each of the number of cells; and determining a total cost for the entity (200) to travel to each of the scanned cells and to perform a scan from each of the scanned cells.Type: ApplicationFiled: July 29, 2003Publication date: April 15, 2004Applicant: Lockheed Martin CorporationInventors: Abha Moitra, Robert M. Mattheyses, Robert J. Szczerba, Louis J. Hoebel, Virginia A. Didomizio, Boris Yamrom

Publication number: 20040068372Abstract: A system for enhancing flight safety of a host aircraft receives an adjustment value from a portable memory device; determines a working value of a parameter in accordance with the adjustment value; and provides an advice for threat avoidance in accordance with the working value of the parameter, a terrain database, and an expected climb gradient capability of the host aircraft. The adjustment value may describe an adjustment to at least one of: an aircraft capability parameter, a flight crew capability parameter, a mission parameter, a threat detection technique parameter, a threat advice parameter, or a threat avoidance parameter. Threats include a risk of colliding with other aircraft, colliding with terrain, and encountering adverse weather conditions.Type: ApplicationFiled: October 3, 2002Publication date: April 8, 2004Inventors: Kathryn W. Ybarra, Zachary R. Reynolds

Publication number: 20040068415Abstract: In a multirobotic system comprised of automated mobile robotic vehicles (MRVs), a network of MRV drones provides sensor information to a lead MRV, which calculates the distance to objects in the environment. By using a method of optic flow to map coordinates in spatial positions, MRVs establish mission priorities and work as a group to accomplish a mission. Once the operational coordination is made for the group to organize its priorities and tasks, the enemy targets are struck in a sequence according to mission parameters.Type: ApplicationFiled: April 22, 2003Publication date: April 8, 2004Inventor: Neal Solomon

Patent number: 6711477Abstract: A system and method for detecting if a UAV is operating within its flight envelope. The invention includes defining the flight envelope of the UAV. The operating state of the UAV is identified from a present time to a future elapsed time. The invention determines if the UAV will be within its flight envelope at the end of the elapsed time in the future. It can then command the UAV to maintain operation within the flight envelope if the operating state determined is outside the flight envelope.Type: GrantFiled: August 29, 2002Date of Patent: March 23, 2004Assignee: Lockheed Martin CorporationInventors: Timothy L. Johnson, Martin E. Kaliski

Patent number: 6697835Abstract: Heterogeneous data at a plurality of remote nodes is accessed automatically in parallel at high speed from a user site using a simple script request containing a data source object name wherein the heterogeneous data is treated as a single data source object, the script further containing code representing a user-defined program to be executed on the data source object. The user-defined program may be represented by an embedded script, a user-defined script or an executable program designation. A user site agent breaks the user-generated script into new scripts appropriate for execution at the remote nodes. A messenger process transmits the new scripts to the appropriate remote nodes where respective agent processes respond to automatically access the appropriate data and to automatically execute the specified program. If the program is a user-defined script or executable, the respective agent processes access a metadata repository to obtain the specified program.Type: GrantFiled: October 28, 1999Date of Patent: February 24, 2004Assignee: Unisys CorporationInventors: Charles Albin Hanson, Thomas Winston Johnson, Carol Jean O'Hara, Koon-yui Poon, Roger Anthony Redding

Publication number: 20040010354Abstract: A system, a method, and a computer program product for determining tactile cueing of a flight control input apparatus includes an interface for receiving observed parameters relating to the flight envelope of an aircraft. Upstream processing elements receive the observed states, convert dimensional aircraft state parameters into nondimensional aircraft state parameters, and provide the data to neural networks. The neural networks receive combinations of observed parameters and nondimensional aircraft state parameters and predict flight envelope limiting parameters. The neural networks are trained to predict the limiting parameters. A downstream processing element determines the most limiting flight envelope limiting parameter provided from the neural networks, therefore providing a tactile cueing position for a flight control input apparatus.Type: ApplicationFiled: May 6, 2003Publication date: January 15, 2004Applicant: The Boeing CompanyInventors: Jeffrey S. Nicholas, David G. Miller

Publication number: 20040006412Abstract: A method and system for providing taxiway navigational information to a crewmember of an airplane taxiing at an airport. An airport taxiway navigation system (“ATNS”) that executes on an onboard computer system that displays a map of the taxiways of an airport, receives the name of each taxiway of the taxi route specified by the taxi clearance, and highlights the taxiways on a displayed map to provide a visual indication of the cleared taxi route for the crewmembers.Type: ApplicationFiled: February 19, 2003Publication date: January 8, 2004Inventors: Reagan Doose, Richard W. Ellerbrock, Glade L. Hulet, John M. Jaugilas, Matthew T. Majka
