The general field of the invention is that of head viewing systems for aircraft comprising a head support, a viewing device, a detection of posture of said head support, means for detecting the current heading of an aircraft and means for graphically generating said heading. The system according to the invention comprises means of control, display and selection of headings arranged so as:

Head-mounted display system comprising heading selection means and associated selection method

The field of the invention is that of viewing systems comprising means for generating stereoscopic images, a viewing device comprising a projector and a semitransparent screen and a pair of stereoscopic glasses. The projector according to the invention comprises means arranged so as to project alternatively a first image emitted at a first wavelength and a second image emitted at a second wavelength different from the first wavelength. The pair of glasses comprises a first filter and a second filter, the first filter transmitting the entirety of the spectrum except a first narrow spectral band centered on the first wavelength and the second filter transmitting the entirety of the spectrum except a second narrow spectral band centered on the second wavelength.

Monochromatic stereoscopic viewing system employing projection onto a semitransparent plate

The general field of the invention is that of display systems comprising an image projector and an associated display screen, the said display system being designed to be used by an observer situated at a given location, the said display screen comprising two transparent and substantially parallel faces, the said display screen comprising, on at least one of its transparent faces, a plurality of regularly distributed light-scattering patterns. The image projector according to the invention illuminating the screen under a plurality of angles of incidence determined by the position and the size of the display screen, the said angles of incidence being centered on a mean angle of incidence, the scattering patterns comprise at least one scattering surface oriented in such a manner as to diffuse the light rays having at least the mean angle of incidence in one or more directions corresponding to the said given location of the observer. Several embodiments are described.

Display system comprising a screen comprising an array of three-dimensional scattering patterns

The general field of the invention is that of display systems including an image projector and an associated display screen, said display system being intended for use by an observer situated at a specified location, said display screen having two transparent and substantially parallel faces, and said display screen having on at least one of its transparent faces a plurality of regularly distributed optical patterns. The image projector according to the invention illuminating the screen at a plurality of angles of incidence determined by the position and size of the display screen, and said angles of incidence being centered on an average angle of incidence, the optical patterns have at least one curved reflective surface orientated so as to reflect the light rays having at least the average angle of incidence in one or more directions corresponding to said specified location of the observer. A plurality of embodiments are described.

Display device comprising a screen having a network of three dimensional reflective microstructures

The general field of the invention is that of display systems comprising an image projector and an associated display screen, the said display system being designed to be used by an observer situated at a given location, the said display screen comprising two transparent and substantially parallel faces, the said display screen comprising, on at least one of its transparent faces, a plurality of regularly distributed light-scattering patterns. The image projector according to the invention illuminating the screen under a plurality of angles of incidence determined by the position and the size of the display screen, the said angles of incidence being centered on a mean angle of incidence, the scattering patterns comprise a diffractive structure in order to diffract the light rays having at least the mean angle of incidence in one or more directions corresponding to the said given location of the observer.

Head worn display

The general field of the invention is that of helicopter cockpit display systems. The system according to the invention comprises at least a first mobile display screen. Depending on the mission and in order to optimize the vision of the external landscape, the mobile screen or screens are moved so that they are either in the field of vision of the pilot, or out of his field of vision. The symbologies displayed are adapted according to the mission and to the position of the screen.

Modular display system for helicopters

The general field of the invention is that of helmet shells made of composite material comprising at least one 'armure' of fabrics impregnated with a resin matrix. Certain parts of the 'armure' are impregnated with a resin matrix comprising an additive adapted to reinforce the mechanical strength of the helmet, the said parts corresponding to the weakest zones of a human head, such as the top of the head or the ears. Preferably, the resin is of the epoxy type and the additive is based on acrylic block copolymers. More precisely, the additive is of the &#x201c;Nanostrength&#xae;&#x201d; brand.

Helmet shell made of composite material

The invention relates to vision equipment including a translucent optical strip covering all or some of the visual field of the user of the said equipment and a device for projecting images onto the said strip in at least one zone of the visual field of the user, called the image-projection zone. The optical strip includes a plurality of zones covered by a layer of material with a controlled coefficient of light transmission, a zone at least covering the image-projection zone and in that the vision equipment also comprises a means for controlling the coefficient of light transmission capable of receiving status information and of controlling the coefficient of light transmission of each of the zones and independently of one another as a function of the said status information. The invention preferably applies to helmet visor equipment or head-up displays for an aircraft cockpit and to vision equipment in the motor vehicle field.

The display device comprises a display screen comprising a bonding surface and a mechanical structure. The display device also comprises a glass protective casing consisting of two sheets of glass and inserts. This protective casing is bonded to the structure beneath the second sheet of glass. The screen is bonded to the inside of the protective casing on only one of the two sheets. The invention proposes a compact protective device for a flat screen which is applied essentially to liquid crystal matrix screens comprising light-emitting diode light. The preferred field of application is that of screens used for aviation.
