The geospatial scene model database may include 3D scene model data, and the collected geospatial image and the reference geospatial image may each include respective 2D image data. The collected geospatial image may have at least one geospatial collection value associated therewith, and the image processor may generate the reference geospatial image based upon synthetically positioning a virtual geospatial image sensor within a geospatial scene model based upon the at least one geospatial collection value.Type: ApplicationFiled: January 10, 2006Publication date: June 12, 2008Applicant: Harris Corporation, Corporation of the State of DelawareInventors: Robert M. Garceau, Guillermo E. Gutierrez, Mark Rahmes, Todd Ham, Joseph Nemethy, Jay Hackett

Publication number: 20080140266Abstract: This invention provide systems and methods for cockpit flight crew preflight planning and subsequent, systematic recall and execution of procedures, ground/inflight navigation, and communications using portable electronic data storage and display devices. A capability is provided within a portable electronic data storage and display device to replace and replicate the typical preflight planning methodology of the individual flight crew member to facilitate execution of a procedures, navigation and communications plan from preflight to postflight. A user may create a usable subset of the potentially thousands of available pages of data or data reference pages stored in the portable electronic data storage and display device, organizing the perhaps 100 or less individual pages of data, static or interactive, desired for a specific leg of the flight in order that required information is immediately available in an expected order of need.Type: ApplicationFiled: October 25, 2004Publication date: June 12, 2008Applicant: ARINC INC.Inventor: Rolf Stefani

Patent number: 7385527Abstract: A smart airport automation system gathers and reinterprets a wide variety of aircraft and airport related data and information around unattended or non-towered airports. Data is gathered from many different types of sources, and in otherwise incompatible data formats. The smart airport automation system then decodes, assembles, fuses, and broadcasts structured information, in real-time, to aircraft pilots. The fused information is also useful to remotely located air traffic controllers who monitor non-towered airport operations. The system includes a data fusion and distribution computer that imports aircraft position and velocity, weather, and airport specific data. The data inputs are used to compute safe takeoff and landing sequences, and other airport advisory information for participating aircraft.Type: GrantFiled: August 23, 2005Date of Patent: June 10, 2008Assignee: Sensis CorporationInventors: Odile H Clavier, David R Schleicher, Sharon W Houck, John A Sorensen, Paul C Davis, Cornelius G Hunter

Patent number: 7383105Abstract: A device performs oxygen flight planning calculations for estimating oxygen usage. The device includes a storage device, an input device for inputting a known flight parameter value into the storage device, and an output device for outputting the known flight parameter value input by the input device. A logic device is configured to control the storage device, the input device, the output device and provide to the output device a further flight parameter. A value of the further flight parameter is calculable by the logic device from the known flight parameter value previously input into the storage device. Upon the further flight parameter being selected by use of the input device, the logic device calculates the value of the further flight parameter and provides the value of the further flight parameter to the output device.Type: GrantFiled: June 18, 2007Date of Patent: June 3, 2008Inventor: John D. Conroy, Jr.

Patent number: RE41396Abstract: A system and method are provided for the efficient entry and display of ground taxi routes on an electronic airport map display. The system may include a touchscreen entry device, a display device, a computer, a map database, a vehicle position sensor and a transmitter/receiver. The system may be configured to check the ground taxi entries to ensure that each successive segment is contiguous with the last or next segment, and any gaps or discontinuities in the displayed taxi instructions may be annunciated. An intelligent display of next possible segments may be incorporated into the system.Type: GrantFiled: June 13, 2008Date of Patent: June 22, 2010Assignee: The Boeing CompanyInventors: Samuel T. Clark, Wayne R. Jones, Michael P. Snow, Eddie J. Trujillo
