A time control device for the movement of a micro-machined or micro-engraved counterweight with respect to a substrate, said counterweight incorporating at least one face having at least one indentation intended to cooperate with at least one other indentation on a housing in which said counterweight moves so as to ensure the delaying of said movement of said counterweight, wherein said one indentation on said counterweight respectively on said housing receiving said counterweight is made on at least one flexible tongue itself integral with said counterweight respectively said housing, said at least one flexible tongue being able to be deformed by bending during the displacement of said counterweight.

A micro-machined or micro-engraved safety and arming device for a projectile pyrotechnic train, said device comprising a substrate onto which a shutter is positioned to ensure the blocking of a channel, said shutter being mobile in translation on said substrate, said shutter being held immobile in the safety position by at least one acceleration lock that is released further to the application of the axial acceleration imparted to said projectile during firing, wherein said acceleration lock is constituted by at least one breakable tongue linking said shutter to said substrate, said tongue being oriented and dimensioned such that the axial inertial stresses developed during firing and exerted on said shutter cause said tongue to break.

Safety and arming device with breakable lock

The invention relates to a safety and arming device for projectiles and using micro-electromagnetic technology, such device incorporating a slider made mobile by the effect of the centrifugal acceleration with respect to the body of the device and immobilized in a safety position by at least one inertial lock, such lock incorporating at least one means to ensure its blocking in the unlocked position, wherein the inertial lock incorporates a counterweight having at least one straight groove whose longitudinal axis is parallel to the direction of movement of the lock, groove in which a fixed guiding pin integral with the safety and arming device is positioned, since the groove is of sufficient length to allow the displacement of the counterweight with respect to the pin, the slider in its safety position being made integral with the body of the safety and arming device by means of hooking means integral with the counterweight.

Safety and arming device for projectiles inertial lock with MEMS technology

A micro-machined or micro-engraved safety and arming device for a pyrotechnic train of a projectile to which an axial spin motion is imparted during firing, the device includes a shutter to interrupt the pyrotechnic and being held immobile by at least two locks, a first lock or axial acceleration lock that is released further to the application of the acceleration during firing and a second lock that is a centrifugal lock released further to the spinning of the projectile.

The present invention concerns a lining support comprising a plurality of conductive pads () associated with a shared addressing contact () and means of selecting at least one pad to be lined by electrochemical means among the plurality of pads. In accordance with the invention, the selection means comprise means () of shifting a polarisation voltage, connected between the shared addressing contact and at least one pad to be addressed. Application to the lining of conductive pads.

Coating support and method for the selective coating of conductive tracks on one such support

An electromechanical microstructure including a first mechanical part formed in a first electrically conductive material, and which includes a zone deformable in an elastic manner having a thickness value and an exposed surface, and a first organic film having a thickness, present on all of the exposed surface of the deformable zone. The thickness of the first film is such that the elastic response of the deformable zone equipped with the first film does not change by more than 5% compared to the response of the bare deformable zone, or the thickness of the first film is less than ten times the thickness of the deformable zone.
