Abstract:
The management of binocular rivalry, and by extension of attentional rivalry, in a display system is provided. The method includes the steps of determining visual surroundings parameters; determining a risk of visual suppression by binocular rivalry between an element of the visual surroundings and an element displayed by the display device on the basis of the visual surroundings parameters; and, on the basis of the determined risk, adjusting the display. Developments of the invention describe the management of the luminance, of the chrominance and of the geometry of the displayed elements. Optimizations in the field of avionics are described. Software and system aspects are described (e.g. brightness sensors and/or gaze-tracking sensors, monocular system).
Abstract:
A dual harmonization method for a worn head-up display system for making the display of piloting information of an aircraft on a display conform with the outside real world includes a step of acquisition of N measurements {circumflex over (K)}ι of head posture detection by a series of sightings Vi corresponding to images oriented according to orientations Oi of one and the same photograph taken by a camera, secured to and aligned with the attitude inertial device D3, then a step of joint computation of the matrices of relative orientation M01 and M23 as joint solutions of the dual harmonization ÛiĜ·{circumflex over (K)}i·{circumflex over (D)}, i varying from 1 to N, in which Ûι is the transpose of the matrix M(image(i)/0) of relative orientation of the image(i) of rank i relative to the display D0, with M01 and M23 respectively equal to the right and left matrices {circumflex over (D)} and Ĝ. A worn head-up display system is configured to implement the dual harmonization method.
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.

The general field of the invention is that of methods of displaying an “attitude director indicator” in a head viewing system for aircraft comprising: a head support bearing a viewing device; a detection of posture; sensors for detecting the various parameters defining the attitude of the said aircraft; means for computing and graphically generating the said attitude, the set of parameters displayed being termed the “attitude director indicator”; In the method according to the invention, when the head support is oriented in a determined direction making, with the horizon line and/or with the “speed vector”, an angle greater than a first value, and/or when at least one of the attitude parameters of the aircraft becomes greater than a second value, the attitude director indicator is displayed locally in a reference frame tied to the head support and in the field of the viewing device.

A navigation aid information display device of an aircraft and primary flight display for an aircraft are disclosed. In one aspect, the navigation aid information display system includes a display screen including at least one first display area configured to display a first altitude scale including graduations, the current altitude of the aircraft on the first scale, and a set altitude value. The graduations of the first scale are distributed on an arc of a first disc including a first needle centered in the disc and the first needle is configured to indicate the current altitude on the first scale. The distribution of the graduations on the arc is nonlinear and symmetrical relative to a graduation corresponding to the set altitude value and defines extension graduations decreasing from the set altitude value.

The helmet shell includes a mechanical arch fixedly mounted on the front part of the helmet, and the mechanical arch includes at least one first device for attaching the binoculars. In the system, the mechanical arch includes a second device for attaching the display device. The display device may include a posture detection device and an adjustment mechanism. The display system may include a mechanical cover which is mounted in place of the display device, the shape of the cover being adapted so as to hide the upper part of the helmet. A mobile visor can be mounted on the mechanical arch.
Abstract:
A method for the three-dimensional representation of the trajectory of an aircraft in flight implemented in a navigation system of an aircraft is provided. The flight plan of the aircraft comprises imposed georeferenced trajectories and predicted non-georeferenced trajectories. When the trajectory of the aircraft is dependent on a non-georeferenced flight setpoint, the three-dimensional representation method is an iterative process comprising the following steps: computing a predicted trajectory arising from at least one computed trajectory extending over a determined distance or duration; computing a smoothed trajectory from the predicted trajectory in order to obtain a resulting trajectory; computing a displayed trajectory, the trajectory being equal to the resulting trajectory corrected for constant deviations or deviations depending on the application of setpoints from the flight director; and displaying the displayed trajectory.
