Improved 'moving red dot' sighting device, including a fixed light source () and a reflecting element (), wherein the light source () produces a collimated light beam () which is projected onto the reflecting element () so as to obtain a red dot or reticle which is visible to the shooter thanks to the reflection on the reflecting element (), and whereby the beam () is projected onto the reflecting element () by means of a rotating mirror () whose inclination angle (B) in relation to the light beam () can be adjusted.

'Moving red dot' sighting device

Improved sighting system for a fire arm, characterised in that it comprises a single indicator light (); a sighting device () providing an alignment opening () with a longitudinal reference plane (XoX') which is parallel or mainly parallel to the axis (Y-Y&#x2032;) of the barrel () and which is aligned with the indicator light (); an inclinometer to measure the elevation angle (A) of the fire arm (); a ballistic calculator () connected to the indicator light () and to the inclinometer, making it possible to calculate the desired angle of inclination of the fire arm () as a function of the distance of the target () and to control the indicator light () so as to signal at what moment the measured elevation angle (A) corresponds to the calculated elevation angle.

Sighting system for a fire arm

Device for detecting and counting shots fired by an automatic or semi-automatic fire arm with a barrel and moving parts to recock the fire arm, sliding in the axial direction (Y-Y') of the barrel between a front position and a rear position, whereby the fire arm undergoes accelerations in the axial direction (Y-Y&#x2032;) of the barrel for every fired shot, caused by a succession of shocks due to the shot being fired and to the movements of the moving parts, whereby the progression in time of the accelerations is typical for a fire arm and for the type of ammunition used, thus forming a typical signature for the fire arm and for the type of ammunition, characterized in that it comprises an accelerometer () with a pass band which is sensitive to shocks in the axial direction (Y-Y&#x2032;) of the barrel and a microprocessor () for analyzing the signal (S) of the accelerometer () while firing, whereby the microprocessor () is equipped with an algorithm to count the number of shots fired, based on the discernment and recording of a shot being fired on the basis of the detection, in the signal of the accelerometer, of all or part of the characteristic elements of the acceleration signature which is typical of the type of fire arm and of the different types of ammunition used, whereby these characteristic elements are recorded beforehand in a memory () of the device.

Process for measuring lengths by means of a photosensitive network camera, characterized in that the process consists in integrating the video signals (V) over all or part of each of the scan lines (BI); following the evolution of the integral (I) during successive scans (BI) in the vicinity of the edges (9); and precisely locating the points in the integral curve (I) corresponding to the edges (9) in the image (8) of the object (1) to be measured.
