Abstract: A drone including a barometric sensor adapted to deliver a drone altitude signal; a sensor for measuring the attitude of said drone, adapted to estimate at least one angle of attitude of the drone, and altitude determination means adapted to deliver a drone altitude value, expressed in an absolute terrestrial reference system. The drone includes a relative wind speed sensor adapted to measure the relative wind speed and the altitude determination means includes a device for memorizing predetermined altitude compensation data, an altitude estimator receiving as an input the signals delivered by the attitude measurement sensor and by the relative wind speed sensor and by the barometric sensor and combining these signals with the altitude compensation data memorized in the memorized device to output the estimated drone altitude value.

Abstract: A compact antenna for centimetric frequency bands includes an active planar element forming a radiator, coupled to an input of a receiver circuit and/or to the output of an emitter circuit, and a passive planar element forming a reflector. The passive planar element is formed by a periodic structure of the metamaterial type comprising a network of resonating cells, in particular cells of the complementary concentric slit-ring type Complementary Split-Ring Resonator (CSRR). A clip-shaped support made of a dielectric material supports the active planar element and the passive planar element.

Abstract: The invention relates to a system for shooting moving images, includes a drone provided with a camera and a ground station communicating with the drone, the camera being directed along a sight axis, the displacements of the drone being defined by flight instructions applied to a set of propulsion units of the drone, the drone being adapted to fly autonomously to shoot moving images of a target moving with the ground station. The system includes control means configured to generate the flight instructions so as to hold substantially constant the angle between the sight axis of the camera and the direction of displacement of the target upon activation of the target tracking. The ground station includes means, controlled by at least one piloting means forming a button for activating the target tracking, to alternatively switch the drone piloting mode between a mode of activation of the target tracking system and a deactivation mode.

Abstract: A method for dynamically controlling the attitude of a rotary-wing drone. The method includes dynamically controlling the attitude of the drone when the drone is flying using lift of each of four wings of the drone, by controlling the attitude of the drone by sending differentiated commands to one or more propulsion units of the drone so as to rotate the drone about a roll axis and/or pitch axis and/or heading axis of the drone from a current angular position to a final angular position, the axes being defined in the reference point of the drone.

Abstract: A vertical-view camera (16) delivers an image signal (ScamV) of the ground overflown by the drone. Gyrometric sensors (102) measure the Euler angles (φ, θ, Ψ) characterizing the attitude of the drone and delivering a gyrometric signal (Sgyro) representative of the instantaneous rotations. Rotation compensation means (136) receive the image signal and the gyrometric signal and deliver retimed image data, compensated for the rotations, then used to estimate the horizontal speeds of the drone. The camera and the inertial unit are piloted by a common clock (160), and it is provided a circuit (170) for determining the value of the phase-shift between the gyrometric signal and the image signal, and to apply this phase-shift value at the input of the rotation compensation means (136) to resynchronize the image signal onto the gyrometric signal before computation of the retimed image data.

Abstract: This headset (10) comprises two earphones (12), a central headband (14) and two lateral branches (16). Each branch comprises at a proximal end a link (20) articulated with the respective end of the central headband (14), providing at least one pivotal degree of freedom. The earphone is mounted, preferably rigidly, on the distal end of the branch. Each of the branches also comprises, in a median region, a bearing pad (40) provided, on an internal side, with a bearing face (48) adapted to come into contact with a temporal region of the headset user, so that this bearing face forms there-on a point of contact. Each branch (16) has, in an intermediate region between a proximal end on the central headband side and a distal end on the earphone side, an elastically deformable link (17) providing a torsional degree of freedom, preferably a privileged bending in a particular plane.
