Abstract: An aircraft seat includes an actuator and a movement transmission device. The transmission device includes a frame provided with an immobilizing portion and a drive shaft. The transmission device further includes a gear wheel provided with coupling teeth having inclined side walls and a sleeve with an immobilizing portion complementary to the immobilizing portion of the frame, and coupling teeth having inclined side walls. The transmission device also has an elastic member configured to push the sleeve. The stiffness of the elastic member and the inclination of the side walls of the coupling teeth of the gear wheel and sleeve are chosen such that, when a torque greater than a threshold torque is applied to the gear wheel, the sleeve slides on the drive shaft from a position of coupling the sleeve to the gear wheel to a position of immobilizing the sleeve relative to the frame.

Abstract: The invention relates to a computing unit, a switch connected to the computing unit, a user terminal connected to the switch in such a way that the computing unit, the switch and the user terminal form a communication system with a central architecture, and at least one communication system with a distributed architecture that is connected to the switch. The switch is designed to be used as an intermediate system for the communication system with the central architecture as well as for the communication system with the distributed architecture.

Abstract: A method of characterizing an inertial measurement unit includes a block carrying one accelerometer positioned on an axis of a measurement reference frame and having one gyro arranged to determine the orientation of the frame relative to an inertial reference frame. The method includes keeping the inertial measurement unit centered on a point that is stationary relative to the ground and that is in a predetermined environment, to obtain accelerometer signals that are images of at least one component of the specific force vector in the measurement reference frame and also gyro signals that are images of at least one component of the instantaneous rotation of the measurement reference frame; processing the signals to obtain data representative of projecting of the specific force vector into the inertial reference frame, after compensating for rotation of the Earth; and calculating Allan variance on the data and comparing it with reference data.

Abstract: A path is defined to be followed by a vehicle in an environment represented by a graph of nodes connected by edges. Each node represents the vehicle's position. Each edge between two nodes indicates a transition cost between the two nodes. An instance of the graph, which is represented by a start node, a destination node and mandatory nodes through which the vehicle must pass, is obtained. An initial order of travel through the mandatory nodes is obtained by applying a procedure, using a graph convolutional neural network, adapted to the graph, to the instance. A procedure of local optimisation of the mandatory nodes is executed in order to obtain an optimised order. A path for the instance is defined to be resolved: from the optimised order and for each pair of nodes of the instance to be resolved, from a shortest path between the nodes of the pair.

Abstract: A method of assisting navigation of a vehicle, the method comprising the steps of: at predetermined instants, determining first positions and second positions of the vehicle by different positioning means and calculating the discrepancy between each pair of first and second positions; comparing the discrepancy with a warning threshold; defining a reference frame on a screen, the reference frame being centered on a reference point corresponding to the most recent first position; and symbolizing the discrepancies on the screen by allocating a symbol to each discrepancy and by positioning each symbol on the screen, relative to the reference point, while taking account both of the value of the discrepancy and also of the path travelled by the vehicle since calculating the discrepancy, the first symbols being provided with respective chronological indicators.

Abstract: A piloting device arranged to be integrated in a pre-existing aircraft that includes original systems comprising both a flight control system and an autopilot system is distinct from and autonomous relative to the original systems and includes a positioning unit and a control unit. The positioning unit is arranged to produce positioning data for the pre-existing aircraft. The control unit is arranged to perform a geofencing function from the positioning data produced by the positioning unit and to produce an alternative piloting setpoint for the pre-existing aircraft. The alternative piloting setpoint is adapted to supplement both a manual piloting setpoint produced by a pilot of the pre-existing aircraft via the flight control system and also an autopilot setpoint produced by the autopilot system.
