摘要： A locked state for a movable part (11) of switchgear is created by deflected spring wires (15) entering a recess (12). Said device is reversible and has the advantage of being safe since it is completely passive, and it improves the dynamics of the movement of the movable part in particular by damping impacts when entering the abutment state. The invention can be applied to the drive rod of a vacuum circuit-breaker.

摘要： The optical fiber interferometer system is used either in a gyroscope or else for measuring electrical current by the Faraday effect. It includes an optical board (100) which is connected to the two ends of a monomode optical fiber (200) constituting an interferometer ring, said optical board including a photodetector (103) which is colinear with the light source which is coupled by both its front and its rear faces. The two counter-propagating beams travelling round the interferometer ring have their relative phase difference modulated by phase modulation and their light power modulated by amplitude modulation. An electronics board (300) generates these modulations and, from the photodetector signal (103), it extracts a component at the lower beat frequency between said two modulation frequencies, thereby making it possible to measure the relative phase difference between the two beams.
