20080211814 | Graphics Generation Device Comprising Means For Monitoring Its Operation - The field of the invention relates to the operational safety, security and reliability of Man/Machine Interface systems displaying information in the form of graphics or symbology. The monitoring principles according to the prior art are all based on monitoring graphical information coming from the display system and the verification that this information really corresponds to the input parameters. The heart of the invention is to monitor the correct operation of the graphics generation functions, independently of the data that they process. More precisely, the invention relates to a device for the graphical generation of symbologies intended for a display screen, the device having functions for the generation of symbology elements and means for monitoring its correct operation. The monitoring correct operation allows the use of certain of the functions for the generation of symbology elements to be prohibited and second allows micro-images dedicated to the monitoring of the functions to be generated and controlled. | 09-04-2008 |
20080252636 | Synthesis Method for Intervisibility Images - The field of the invention is that of synthesis methods for a map image which is composed of pixels and represents the distribution of the intervisibility regions on a terrain overflown by an aircraft. The image synthesis method according to the invention provides both a two-dimensional cartographic representation in plan view of a terrain (T) overflown by an aircraft. The terrain has at least one potential threat (M), the intervisibility region, set of locations from where the aircraft is likely to be visible to said threat, being represented by at least one plain color. A second representation represents a view in vertical cross section of the terrain overflown. The second representation has a cross-sectional view of the intervisibility region. Various configurations of the first and of the second representations are proposed. | 10-16-2008 |
20090243893 | METHOD OF CODING A DIGITAL COLOR IMAGE INCLUDING MARKING INFORMATION - The field of the invention is that of the dependability of operation of viewing systems. The field of application is more particularly that of cockpit systems on board aircraft. The invention relates to a method of coding the pixels of a color digital image comprising critical symbols represented by critical pixels, each colored pixel being coded on three digital components each comprising the same number of bits. The components of the critical pixels comprise on the one hand color information and on the other hand a marker also called a “tag” coded on at least one bit, said marker being intended to be utilized by functions for generating and predicting the critical symbols. | 10-01-2009 |
20100066564 | VIEWING DEVICE INTENDED FOR COMPREHENDING THE AERIAL ENVIRONMENT - Device for viewing the aerial environment for aircraft, including a display, a processor and memory configured to generate and to provide a first data processing resource, the data being a graphical representation of the aerial environment composed of colored zones, each color being associated with a danger level for the aircraft, said data comprising environmental data; and a second data processing resource for cartographic data. The device further comprises a graphical mixer to overlay the graphical representation arising from the environmental data onto a representation of the cartographic data on one viewing screen, each zone of a color of the representation of environmental data having a transparency coefficient dependent on the danger level. | 03-18-2010 |
20100070113 | DEVICE FOR SERVOING GRAPHIC REPRESENTATIONS OF THE AIR ENVIRONMENT - Device for servoing graphical representations of the aerial environment for aircraft, an avionics the device including a display, a computer and memory in communication with the computer, the memory storing means for generating images of environmental data, said data being servoed by the first calculation resource and periodically refreshed in a first time interval. The device comprises a calculation resource providing an angle of heading of the aircraft relative to North and its geo-referenced current position, these data being servoed, periodically, in real time in a second time interval. The representation of a part of the environmental data on the viewing screen of the device is servoed and refreshed during the second time interval and positioned and oriented graphically, by the display, according to the last current angle of the position of the aircraft calculated and of the last geo-referenced current position. | 03-18-2010 |
20100201544 | Method for Presenting Air Traffic Information on an Aircraft Head-up Display - The general field of the invention is that of air traffic detection systems for a first aircraft, said system having detection capabilities in a region situated about said first aircraft, said system comprising at least one head-up display device, said device comprising means of generating, collimating and superimposing symbols on the external landscape intended to assist in the piloting of said first aircraft in the horizontal and vertical planes. When a second aircraft is detected by the air traffic detection system, the display device displays a specific system of symbols representative of the location of said second aircraft. The position and the configuration of this system of symbols depend on the position of the second aircraft in relation to the first. It also depends on the type of system, depending on whether the latter is an anticollision system or a guidance system. | 08-12-2010 |
20100309025 | Method of Presenting Anti-Collision Information in a Head-up Display for Aircraft - The invention relates to a method for managing an anti-collision system for aircraft, said system comprising means of detecting collision with a threat and at least one head-up viewing device. The symbol system comprises two display modes dedicated to collision detection which are: on the one hand an “action” mode: a potential collision is detected by the system, the symbol system comprises at least one symbol representative of the limits of the disengagement path of the aircraft to avoid the collision and enabling the pilot to engage his avoidance maneuver, and on the other hand a “control” mode: this mode is displayed when the avoidance maneuver is engaged and the collision avoided, the symbol system comprises at least the symbol representative of the limits of the disengagement path of the aircraft and a plan view representing the air space around the aircraft and including at least one representation of the threat. | 12-09-2010 |
