Abstract: A satellite platform is disclosed having a plurality of radiating elements configured to receive and/or transmit electromagnetic radiation and including at least one transmitter radiating element, and at least one block of material that absorbs electromagnetic radiation in a frequency band of interest in order to decrease electromagnetic coupling between the radiating elements. The block of material is implemented in at least one region of interest in the satellite platform to decrease electromagnetic coupling, the region of interest intersecting at least one predominant coupling path between at least two of the radiating elements.

Abstract: An assembly for supplying power to an aircraft is disclosed having at least one battery housed in a respective housing, each housing comprising a wall in which a through-opening is arranged, and an exhaust device including a discharge duct connecting each housing opening to a common discharge port, a valve mounted on each opening. Each valve includes a membrane arranged so as to seal the opening closed and having a surface of pressure application towards the inside of the housing and a surface of pressure application towards the outside of the housing. The surface of pressure application towards the outside of the housing is larger than the surface of pressure application towards the inside of the housing, so that the membrane bursts at a bursting pressure inside the housing that is lower than a bursting pressure reached outside the housing.

Abstract: Simulation sighting binoculars include a camera, a screen, a pair of lenses which are arranged to face the screen, and electronic circuitry which is configured to: obtain a video frame from the camera; transmit, to a simulation platform, geolocation information and orientation information for the camera; receive simulation graphical elements and spatial positioning information for corresponding virtual objects; carry out a two-dimensional rendering of the virtual objects, in order to display them in a projection window E2; superimpose the two-dimensional rendering of the virtual objects in the projection window E2 and the video frame in a projection window E3; obtain a mixed-reality stereoscopic image using a pair of virtual cameras reproducing binocular vision which is adapted to the pair of lenses; and carry out, on the screen, a right-eye and left-eye display of the obtained mixed-reality stereoscopic image.

Abstract: A system for fastening a mirror to a support is disclosed including intermediate structures, for example bipod structures. At least some of the intermediate structures are provided with torsion devices making it possible to at least partially compensate for optical aberrations of an instrument that includes the mirror. Each torsion device may comprise an elastic element and a variator. The variator is designed to control a deformation of the elastic element, resulting in a torque which is applied to the mirror.

Abstract: A demosaicing method applied to an image having pixels each corresponding to an initial spectral band, to obtain a demosaiced image with several spectral bands having pixels each corresponding to the initial spectral band or to an interpolated spectral band. The method includes: on the basis of reference patches and for each reference patch: a determination of a set of patches similar to the reference patch, a determination of a covariance matrix for |the set of patches, and for each patch, a calculation of estimates of the interpolated spectral bands according to a block-based deconstruction of the covariance matrix, where the deconstruction into four blocks is according to phasing of each patch, and a determination of the interpolated spectral bands by an aggregation of estimates of the interpolated spectral bands, where the estimates of the interpolated spectral bands are aggregated for each pixel.

Abstract: A terminal (100) for optical communication by laser signals including a matrix image sensor used as a tracking and acquisition detector (2). The matrix image sensor is used simultaneously to check that a portion of the laser signals received by the terminal are injected into an optical fibre (1). A spectral filter element (22) is associated with the matrix image sensor to allow such a combination of functions.
