The present invention provides a device for controlling the movement of a vehicle closure element, the device comprising, interposed between a vehicle structure and a closure element, firstly a driver element that can be activated on command, constituted by a pyrotechnic actuator, and secondly mechanical connection means suitable for allowing a driving connection between the pyrotechnic actuator and the closure element when the pyrotechnic actuator is activated, while also allowing the closure element to move freely relative to the pyrotechnic actuator when the closure element is moved over a stroke greater than that enabling said driving connection.

The invention concerns an igniter plug for a pyrotechnic device, in particular a hand-launch or mechanical launch grenade, comprising a body ( ) provided with a control mechanism including a fly-off lever ( ) and a percussion mechanism ( ) co-operating with a primary pyrotechnic module ( ) for initiating the charge ( ) of the associated device. The invention is characterised in that it further comprises a lock ( ) engaged with the lever ( ), in storage position, to prevent the fly-off lever ( ) from moving towards its release position, the lock ( ) being configured to impose, when the igniter plug is activated, an initial movement of the lever ( ) countering its displacement required for releasing the percussion mechanism ( ), so as to disengage the lock ( ) and the fly-off lever ( ).

The invention relates to a radioaltimeter type detector comprising an oscillator-transmitter (10), a modulator (20) suitable for frequency modulating the oscillator-transmitter according to a given characteristic, a mixer receiving the signal from the oscillator-transmitter and a corresponding echo signal reflected by a target, and a discriminator circuit (50, 60) connected to the output from the mixer. According to the invention, the modulator (20) includes a digital memory (21) containing a series of values defining the frequency modulation characteristic of the oscillator-transmitter (10).

A shoulder-borne weapon for use as a rocket launcher is disclosed. To enable its use in an enclosed space with any complication or excess weight, and without imposing any appreciable recoil effect on the gunner, for all that, at least one weapon tube is guided in limited longitudinal, sliding motion with respect to a barrel comprising shoulder rest means, grip means and firing control means, and means are provided to exert force elastically on the weapon tube, frontwards with respect to a pre-determined firing direction, so as to dampen the recoil motion of the weapon tube with respect to the barrel.

A pressure plate for a mine comprises a hydraulic circuit. The mine is triggered by complete depression of the pressure plate. The hydraulic circuit comprises a pressure chamber containing a fluid that is compressed by a force applied to the pressure plate. The fluid is evacuated from the pressure chamber in a controled manner through a depressurization unit in response to a sustained force greater than a predetermined threshold being applied to the pressure plate. A bistable member moves between a first position in which it prevents communication between the pressure chamber and the depressurization unit and a second position in which it establishes communication between the pressure chamber and the depressurization unit. The bistable member is initially in the first position when no force is exerted on the pressure plate. It remains in the first position so long as the pressure plate is subjected to an increasing or stable force. It switches to the second position when the pressure of the fluid decreases after it has increased due to a force of this kind. Thus, after increasing to a maximum value and then decreasing to a minimum value, any increase in the force results in depressurization of the fluid and complete depression of the pressure plate. This explodes the mine.
