Viewing device for aircraft comprising means of displaying the final destination and associated display method

A method for the analysis of a message given by an interaction device to a system of man-machine dialog includes three consecutive steps, a first step of syntactic analysis, a second step of semantic analysis and a third step of execution analysis. The syntactic analysis assesses the conformity of a message given by the interaction device with a predefined form of dialog, the semantic analysis assesses the meaning of the request made by the operator engaging in dialog with the machine, and the execution analysis determines the performance of an action to be undertaken coming from the step of semantic analysis. The invention finds particular application in systems of man-machine dialog having many kinds of interaction such as speech, gesture, and expressions.

Method and device for the analysis of a message given by interaction

The invention concerns a system for the management of an interaction system between a man (41) and a machine (12). Data input into the system are output by interaction devices (1, 2, 3, 4) from the man to the machine. At least two functions (7, 8, 9, 10) operate simultaneously on data (24, 25, 26), data input into the system being processed by a first function (7), the result of one function forming input data for the next function. The result of the last function (10) is output to interaction devices (11) from the system to the man. Functions are synchronized with each other by an exchange protocol.

Management method for a man-machine interaction system

The disclosed device comprises an image circuit formed by an image generator, a micro-zone processing unit, a screen interface and an LCD screen. To optimize the performance characteristics of the screen as a function of the angle of observation, the position of the observer is detected (by a detector) and, as a function of this position, the appropriate profile of luminosity of the micro-zones of the screen is selected.

Method and device for the optimizing of the performance characteristics

The disclosure relates to the display, by projection on a screen, of an image managed by a computer system and to the input of data into the data-processing system by the shifting of a location marker in relation to the screen. A device for display by the projection of an image on a screen incorporates a surface detector of infrared radiation positioned behind the projection objective by means of a mirror separating the visible radiation and the infrared radiation. This display device is complemented by an infrared emitter with directional radiation, with which the observer traces a location marker on the screen which may take the form of a visible pointer overprinted on the image.

Combined device for screen display and for the detection of the position

A device for receiving a television image and for processing it in real time for display on a different type of screen. The incident television image is digitized and then a micro-zone, selected from a series of predefined micro-zones stored in a screen memory, is assigned to each pixel in the incident image. The image is written into the memory, micro-zone by micro-zone, and then read for display on the screen. Each micro-zone is selected to represent the incident pixel in a way appropriate to the format conversion and/or transformation to be applied to the image.

Real time device to display television images on a screen

The system comprises, connected to an image generator (14), a processing unit (13) with a management unit (18), a microregion generating unit (20) and correlation circuits for selecting, for each point of the image with coordinates x, y, one of a series of predetermined pixel microregions stored in the generating unit (20) in order to correlate it in x, y, in the correlation circuits, with the previously presented microregions, before writing it in a screen memory (22) and presenting it on the screen (16). The screen memory (22) is integrated in the processing unit (13) and has a matrix of memory cells (22.sup.1 -22.sup.16), organised in an identical manner to that of the microregion pixels, associated with a single matrix address bus (26) enabling the memory cells to be addressed simultaneously and connected to a generator (19) of the addresses of the memory cells and the processing unit (13) is directly connected to the image generator (14). The invention can be applied well in avionics.

An optical mixer for use in a helmet visual display system including a light intensifier tube for night vision and a cathode-ray tube for the display of a synthetic image. The mixer includes a swinging glass plate with a spectrally reflective and angularly selective coating. When the angle of the swinging glass plate is changed, the amount of light transmitted through the mixer is changed.

The device finds application, particularly, in the instrument panels of aircraft, where it comprises: three liquid crystal optical valves, controlled by three electrical signals respectively representing a red image, a green image and a blue image. Two holographic mirrors are utilized, as is a standard mirror and two dichroic strips to illuminate the three valves respectively by three beams, colored red, green and blue, from a single source of white light, while at the same time reducing the space occupied by the optical elements needed to guide the three beams to the minimum. A dichroic cube then superimposes the three beams coming respectively from the three valves and an optical system to form a trichromatic image on a diffusing screen. The optical system collimates the rays coming from the image formed on the diffusing screen to enable an observer to see an image collimated at long distance, with a wide field.

High definition color display device

The disclosure relates to optical devices enabling daytime vision and night vision of an external scene with, in both cases, the superimposed introduction, into an observer's visual field, of an image given by an image generator. The image given by the light intensifier of a night observation system is processed in the same way as the image given by the image generator, by an auxiliary image-combining optical system which mixes these two images before they reach the main image-combining optical system of the device through which, in night vision, the observer directly sees the external scene. The auxiliary image-combining optical system is designed so that, in night vision, at least the greatest part of the light coming from the image generator reaches the main image-combining optical system. Depending on the embodiment, this result is obtained either with a retractable semi-reflecting mirror or with a semi-reflecting surface selective in frequency.

Optical device designed for the introduction of a collimated image into

The system provides for a function of smoothing, and therefore, softening the contours without any loss in addressability, as well as for the homogenization of the spatial distribution in the screen. It has a microprocessor based management and control circuit, an image generator, an image memory, a scanning circuit in X and Y directions and a video processing set placed between the memory and the matrix screen display device. The management and processing circuits are determined so that the matric scan is done by taking into account, for each image point to be displayed, data stored in a zone of the image called a micro-region, formed by at least three pixels in X and at least three pixels in Y, the micro-region being centered on the coordinates of the image point to be displayed.
