Device for dehumidifying a closed casing. The device for dehumidifying comprises a box comprising an inlet communicating with the interior of the closed casing and an outlet, a heating module able to be controlled to generate heat, a desiccant configured to adsorb moisture when it is not heated by the heating module and to return adsorbed moisture by desorption when it is heated by the heating module, a mobile plug able to be moved to alternately open and close the inlet and the outlet, a bias spring configured to move the mobile plug when the heating module does not heat the desiccant and a shape memory alloy spring configured to move the mobile plug when the heating module heats the desiccant, said shape memory alloy spring being able to be heated by the heating module at the same time as the desiccant. The device for dehumidifying is suited for dehumidifying any type of closed casing, it is cost efficient both in design and in power consumption, and it is easy to implement thanks to its small size and its simple design.

A device, for non-destructive testing of a mechanical part made of a polycrystalline material, includes: an ultrasonic probe including a two-dimensional array of transducers capable of emitting and receiving signals at different excitation angles; and a processing module suitable for controlling the emission and the reception of the transducers, for processing the signals received by the transducers so as to express the signals received by the ultrasonic probe in two planar wave planes constructed from the emission and reception wave vectors of the probe, and for deducing therefrom information representative of the three-dimensional orientation of the fiber structure of the mechanical part.
