Abstract:
The general field of the invention is that of display systems comprising means for generating images of a predetermined object and a display device comprising a semi-transparent projection screen. The system according to the invention is intended to be used simultaneously by at least two observers. The image generating means comprise features arranged to generate a first image of a first object and a second image of a second object, and the display system comprises two pairs of glasses worn by the first and second observer, arranged such that the first observer sees only the first image and not the second image and the second observer sees only the second image and not the first image, each pair of glasses allowing the exterior light to pass through. The first object and the second object may be identical.
Abstract:
Hover hold aid systems for helicopters are described. One system comprises a navigation system that determines a helicopter's current position in relation to a terrestrial frame of reference and a helmet-mounted visualization system comprising a helmet-mounted display (HMD) and at least one symbol generation processing device that generates symbols in the HMD at fixed positions in relation to the terrestrial frame of reference. The symbols are displayed in an angular field of display of the HMD. When the helicopter has to home or stay in a vicinity of a predetermined position, the at least one symbol generation processing device calculates a first and a second representation containing a first target and a second target referenced in the terrestrial frame of reference. The first target is located in the direction of the homing course to the predetermined position. The second target is located in a direction perpendicular to this same course.
Abstract:
The general field of the invention is that of visualisation systems for an aircraft comprising a semi-transparent screen and electronic means suitable for generating a symbology displayed on said semi-transparent display screen, the symbology representing a parameter necessary for the piloting or navigation of the aircraft. The symbology according to the invention is partially or totally located on the periphery of the screen and comprises at least one moving pattern or a plurality of moving patterns, the speed and direction of the movement representing the relative difference between the value of the parameter at the present time and a reference value of said parameter, the patterns being immobilised when the value of the parameter at the present time attains said reference value. Different representations and different movements of the patterns are possible.
Abstract:
A data-input device comprises a designator able to point to a position on a screen of a computer system to which the device is intended to be connected and a body intended to be fixed to a workstation, the body comprising a support zone intended to support the hand of an operator as he manipulates the designator. The device further comprises a knob arranged in such a way that it can be manipulated by the fingers of the operator, his hand remaining supported on the support zone. The knob is configured to allow at least two distinct data selections of which one is a choice of values in a series and one is a binary acquisition in relation to the chosen value.
Abstract:
The general area of the invention is that of hover hold aid systems for helicopters. The system comprises navigation means; a helmet-mounted visualization system containing a helmet-mounted display incorporated in the pilot's helmet and means for generating symbols in said helmet-mounted display at fixed positions in relation to a terrestrial frame of reference, said symbols being displayed in the angular field of display of the helmet-mounted display. When the helicopter has to home or stay in the vicinity of a predetermined position, the symbol generation means calculate a first and a second representation containing a first target and a second target referenced in said terrestrial frame of reference, the first target located in the direction of the homing course to the predetermined position, the second target located in a direction perpendicular to this same course.
