摘要:
A system and method for displaying obstacles in a conformal perspective view. The system comprises a display screen for graphical display of data, at least one obstacle data source, one or more graphics processors for receiving obstacle data from the at least one obstacle data source, and for providing input to the display screen. The display screen displays obstacles in a 3-dimensional graphical representation of real space. The display size of the obstacles varies based on the distance to the obstacles. Obstacles located beyond a selected distance are displayed as semi-transparent line objects and obstacles located within the selected distance are displayed as semi-transparent polygons.

The present invention provides a method of authenticating a pair of correspondents in a communication system, such as in a mobile phone network by utilizing a blend of public-key cryptography and symmetric cryptography. Each session between the mobile phone and the network consists of public-key based mutual authentication and key exchange followed by symmetric-key secure data exchange.

Methods and systems are provided for indicating the relationship of a displayed area on a map with respect to a route or flight plan. A method comprises displaying a navigational map on a display device and displaying a graphical adjustment element on the display device. The position of the graphical adjustment element on the display device corresponds to the along track distance between the displayed area of the navigational map and a first navigational reference point of a route comprising the first navigational reference point and a second navigational reference point.
摘要:
A display system and method for a display, in real-time, of a confidence display, displaying the protected airspace associated with a projected trajectory of a first aircraft and the protected airspace associated with a projected trajectory of at least one additional aircraft during a phase of flight. The system processes data representative of a phase of aircraft flight of a first aircraft and at least one additional aircraft and determines the protected airspace associated with a projected trajectory of each aircraft based at least in part on the processed data. An image representative of the determined protected airspace of each aircraft is displayed on the display system as a confidence display.
摘要:
A method of providing certificate issuance and revocation checks involving mobile devices in a mobile ad-hoc network (MANET). The wireless devices communicate with each other via Bluetooth wireless technology in the MANET, with an access point (AP) to provide connectivity to the Internet. A Certificate authority (CA) distributes certificates and certification revocation lists (CRLs) to the devices via the access point (AP). Each group of devices has the name of the group associated with the certificate and signed by the CA. A device that is out of the radio range of the access point may still connect to the CA to validate a certificate or download the appropriate CRL by having all the devices participate in the MANET.
摘要:
An airport lighting aid simulation system comprises a data storage unit configured to store lighting aid data relating to a plurality of airports. The lighting aid data indicates a type and a location of an airport lighting aid at a runway at each airport. The system also includes a display unit and a processing unit operatively connected to both the data storage device and the display unit. The processing unit is configured to receive an input signal indicative of a target runway, to retrieve a sub-set of the lighting aid data from the data storage unit, the sub-set being indicative of a target runway lighting aid, and to control the display unit to display a target runway description. The system enables a pilot to determine whether a visible runway is the target runway by comparing a view from an aircraft as the aircraft approaches the visible runway with the target runway description.

A system is provided for monitoring an energy height of an aircraft during landing. The system includes a database including landing distance data; a processing unit configured to receive the landing distance data from the database and to calculate a landing distance of the aircraft based on a velocity and a height of the aircraft, the processing unit further configured to provide display signals based on the landing distance; and a visual display coupled to the processing unit and configured to provide a visual image based on the display signals.
