Abstract: A method for controlling an aircraft comprising at least two engines, each engine being arranged in its own engine compartment, each engine being connected to a fuel supply circuit provided with its own fuel supply cut-off for cutting off a fuel supply, the aircraft comprising at least one fire detector in each engine compartment, the aircraft comprising at least one first extinguisher and one second extinguisher. An automatic assistance phase comprises, in the event of fire being detected in an engine compartment, automatically and with an avionics system, activating the fuel supply cut-off of the engine present in the compartment concerned, then triggering the first extinguisher, then triggering the second extinguisher in predetermined respective conditions.

Abstract: A method for monitoring the operation of a power plant of a rotorcraft and a rotorcraft comprising at least one lift rotor rotated by the power plant comprising at least one engine. Such a rotorcraft comprises a monitoring system comprising at least one failure sensor detecting a regulation failure affecting a regulation system of the at least one engine, a speed sensor measuring a current speed of rotation of the at least one lift rotor and a controller determining whether there is a condition of compatibility or a condition of incompatibility between a current flight phase and the speed of rotation.

Abstract: A system for handling biological cells includes a main channel having an inlet end and an outlet end, and, at least over a first portion from the inlet end, including a cross section such that a cell circulating in the portion undergoes mechanical stresses. The system further includes first means for detecting the presence of a cell at the inlet end of the main channel and at least one access zone opening into the main channel between its inlet end and its outlet end in the first portion, in order to make it possible to exert an action on the cell. The system also includes means for displacing the cell in order to control the displacement of the cell between the inlet end and the outlet end.

Abstract: Device for locating biological cells of at least one size, including a fluid cavity (3), fluid connection means (6.1, 6.2) configured to allow the introduction of liquid and cells into the fluid cavity, a plate (4) provided with an accommodating surface (8) having properties of adhesion vis-à-vis cells, said plate (4) being suspended in the fluid cavity (3), means (10) for vibrating the plate (4) in at least one stationary mode including at least one actuator (16) intended to act on the plate (4) and a control unit (UC) configured to control the at least one actuator so as to actuate the vibrating plate in a stationary mode at a wavelength greater than the size of the cells.
