Abstract: An adaptive masking method for an element in a field of operations. According to this method, at least one cover allowing to cover the element is implemented, the cover carrying at least one image generator network connected to an image synthesizer coupled to a camera. According to this method, the camera is positioned so as to cover both a portion of a background of the element and the entire cover, the image synthesizer controlling the at least one image generator network so as to minimize the contrast and optionally the frequency deviation between the background and the cover. The device implementing such a method is described.

Abstract: A monolithic impeller includes a gear opening defined by a cylindrical member and an inner surface being splined for receiving a gear shaft and defining an impeller axis. A plurality of blades each include an arcuate configuration extending outwardly relative to the impeller axis. The blades include a proximal end disposed proximate the cylindrical member and a distal end disposed radially outwardly from the cylindrical member. A cover member extends radially outwardly to the distal end of the plurality of blades and defines a fluid inlet that is concentric with the impeller axis. A hub member is spaced from the cover member by the blades extending radially outwardly from the cylindrical member. The proximal end of the blades extend radially inwardly of the fluid inlet and the distal end of the blades terminating at a common concentric diameter as an outermost portion of the cover member and the hub member.

Abstract: The invention relates to a method for acquiring the coordinates of a trigger point (P) of a projectile (4) above a field part (1) on which a target (5a, 5b, 5c) is located. The method is characterized in that it comprises the following steps: emission of at least one laser pulse having a pre-determined duration and directed towards the target (5a, 5b, 5c); reception of the images reflected with a receiver equipped with means for the synchronous visualization of the laser pulses originating from a piece of observation of the field part (1); recovery of the coordinates of a desired trigger point (P) when the operator has chosen a location after the piece of observation was moved. The invention also relates to a fire-control system using such a method.

Abstract: A method for acquiring the coordinates of a trigger point of a projectile above a plot of land on which a target is located, said method being characterized in that it includes the following steps: performing a three-dimensional acquisition of the plot of land using a laser observation means, constructing by calculation, and then displaying an image of the plot of land from a bird's eye view observation direction, and recovering the coordinates of the trigger point desired for the projectile after the positioning said area on the image of the land. The invention also relates to a fire control implementing such a method.

Abstract: A stabilizing device for a small fire arm comprising means (12) to uncouple the cannon with respect to the firer, hinged linking means (14) which are mounted between the cannon (5) and the uncoupling means (12) to enable the cannon (5) to swivel with respect to the uncoupling means (12), and means (15) to control the swivelling of the cannon (5) in order to offset parasitic movements imparted to the fire arm by the firer during sighting thus holding the cannon (5) in the line of sight fixed by the firer.
