A worn head-up display system is configured to implement the dual harmonization method.

Abstract: The general field of the invention is that of systems for detecting the posture of a moving object. The system may include a fixed electro-optical device of known orientation comprising an emission source, an image sensor and image analysis means, and an optical assembly comprising an optical retroreflector arranged on the moving object. The optical retroreflector of the system is an optical sphere of variable index comprising a transparent hemisphere and a reflecting hemisphere. It comprises a meshing comprising at least three opaque wires, of small thickness and known geometrical arrangement. The image of the retroreflector lit by the source forms a reflection on the image sensor, said reflection comprising at least the two images of the shadow of one of the three wires. The image analysis means detect the orientation of the leak line given by said images, said orientation being representative of one of the parameters of the posture of the moving object.

Abstract: A method is provided for two-dimensional graphic representation on an aircraft display screen of an image or of a symbol or of a symbology (PE) whose three-dimensional coordinates in a terrestrial reference frame are known. The graphic representation of the object or of the symbol is stretched in a vertical axis by a constant factor (α) lying between 1.0 and 1.2, the stretching having, for its neutral plane, the local horizontal geographic plane containing the aircraft. Furthermore, when the symbology is a pitch scale consisting of graduations, two successive graduations being separated by a constant angular value, the graphic representations of two successive graduations of the pitch scale are separated by a constant distance on the display screen.

Abstract: The general field of the invention is that of systems for detecting the posture of a mobile object in space. The system according to the invention comprises an electro-optical device comprising a light source, a photoreceptor and means of analysis, and a retro-reflecting cube corner disposed on the mobile object. The cube corner comprises a mask disposed on its entry face. The source emits a parallel or almost-parallel pencil beam. The electro-optical device comprises means for deviating, about a fixed point, the said pencil beam of light by an angle varying as a function of time. The photoreceptor is configured for receiving the pencil beam of light retro-reflected by the cube corner. The means of analysis are configured in such a manner as to determine, based on the signal coming from the photoreceptor, the position of a number of points representative of the borders of the mask and, using this positional information, the posture of the cube corner in space.

Abstract: A dual harmonization method for a head-worn display system for making the display of piloting information of an aircraft conform with the outside real world includes a step of acquisition of N measurements {circumflex over (K)}l of head postures by a series of different sightings Vi, each of which aligns a sighting pattern, situated at a different fixed position Pi on the display D0 with a sighting vector that is a function of the position Pi, then a step of computation of the matrix of relative orientation M01 between the display D0 in a tilted position of engagement in the field of view and the tracking first element D1 as the right matrix {circumflex over (D)} that is the solution of the dual harmonization system of equations Ĝ·{circumflex over (K)}i·{circumflex over (D)}·{right arrow over (x)}i={right arrow over (y)}0 for i varying from 1 to N, the vector {right arrow over (y0)} denoting the vector in the inertial reference frame of the platform corresponding to the target point targeted in the outside real world and being unknown; and the left matrix Ĝ being the matrix M23 of relative orientation between the fixed second element D2 and the attitude inertial device D3, which is potentially incorrect but assumed constant as a function of time, and which, when it is unknown, requires at least four measurements {circumflex over (K)}l.

Abstract: The general field of the invention is that of touchscreen devices with projected capacitive detection comprising a matrix touchpad comprising a plurality of conducting rows and of conducting columns, the matrix touchpad linked to an emission voltages electronic control system and a reception voltages electronic system. The emission voltages electronic control system generates two periodic emission voltages emitted at two different frequencies. The analysis of the reception voltages, by the reception voltages electronic system, makes it possible to determine the positions of two simultaneous presses on the touchpad, including when the two presses are done on rows or columns that are close. The determination of the presses is performed essentially by calculating the barycenters of the troughs of the reception voltages.
