Abstract

A fuze for detecting an obstacle in proximity, an obstacle in proximity defined as being an obstacle exhibiting a minimum distance from the fuze, wherein the fuze comprises at least: an emission device emitting a light beam directed forward of the fuze; a reception device detecting the luminous fluxes in a cone directed forward of the fuze, the light beam and the cone having relative orientations such that they cross one another; a detection volume being the volume where the light beam crosses the cone so that when an obstacle is in the detection volume, the light emitted by the emission device is backscattered toward the detection device, an obstacle in proximity being detected by detecting the maximum of backscattered power, the reception cone is centered on the axis of the fuze.

Abstract

The present invention relates to a fuze, the purpose of which is to detect a nearby obstacle, a nearby obstacle being defined as an obstacle which is at a minimum distance from said fuze, said fuze (30) comprising at least: an emission device (33) which emits a light beam (31) in front of said fuze; and a reception device (34) which detects the luminous flux in a cone (32) in front of said fuze, said light beam and said cone being oriented relative to one another such that they intersect; a detection space (35) being the space where said light beam intersects said cone in such a way that, when an obstacle is in said detection space, the light emitted by said emission device is back-scattered toward said detection device, a nearby obstacle being detected by the detection of the maximum back-scattered power, and said reception cone (32) is centred on the axis (40) of said fuze.

Abstract

An ammunition safety priming device using silicon micro-mechatronic systems technology, having at least two priming safeties intended to be deactivated by as many external independent physical events, includes at least one movable element, along a translation axis, for deactivating at least one of the priming safeties by action on said movable element of one of the physical events. Said movable element is produced in a material other than silicon. The device has applications including ammunition, rocket stage separation devices, and airbags.

Abstract

The invention relates to a safety priming device for ammunition using the technology of silicon micro-mechatronic systems having at least two safety priming devices to be deactivated by the same number of external separate physical events, comprising at least one element (40) that is movable along a translation axis EE' for deactivating at least one of the priming safeties by means of the effect of one of the physical events on said movable element. Said movable element (40) is made from a material other than silicon. The invention can be used for a safety device for ammunition, devices for separating stages in rockets, and for airbags.
