Abstract
Abstract The device for practicing the aiming of a firearm at a target (5), which ice comprises an optical aiming system for a light beam (11,12,13), more particularly a laser beam, directed at the target, at least one retro reflector (6) which is intended to reflect the light and which is fitted to the target (5), and arrangements for the observation of the reflected light, is characterized in that it comprises several different groups (1,2,3) of retro reflectors (6).

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
89 words
A system for practicing aiming a firearm at a target comprising: a target having first and second target areas with first and second degrees vulnerability, respectively; first and second groups of retroreflectors mounted to the first and second target areas, respectively, the first and second groups of retroreflectors arranged in first and second visually distinguishable patterns with first and second densities, respectively; and an optical aiming system for directing an electromagnetic beam at the target and for receiving electromagnetic radiation reflected back from one of the groups of retroreflectors.
Claim 2
Independent Claim
89 words
A system for practicing aiming a firearm at a target comprising: a target having first and second target areas with first and second degrees vulnerability, respectively; first and second groups of retroreflectors mounted to the first and second target areas, respectively, the first and second groups of retroreflectors arranged in first and second visually distinguishable patterns with first and second densities, respectively; and an optical aiming system for directing an electromagnetic beam at the target and for receiving electromagnetic radiation reflected back from one of the groups of retroreflectors.
Claim 3
Dependent Claim
29 words
The system of claim 1 further comprising: an indicating system, coupled to the optical aiming system, for providing an indication of the target area illuminated by the electromagnetic beam.
Claim 4
Dependent Claim
51 words
The system of claim 2 wherein the indicating system includes a television type monitor to permit a user to visually ascertain the degree of vulnerability of the target area illuminated by the electromagnetic beam based upon the pattern of the retroreflectors in the group of retroreflectors illuminated by the electromagnetic beam.
Claim 5
Dependent Claim
18 words
The system of claim 2 further comprising a second one of said indicating system, positioned near the target.
Claim 6
Dependent Claim
14 words
The system of claim 1 further comprising a plurality of said first target areas.
Claim 7
Dependent Claim
51 words
The system of claim 1 wherein the target has a third target area with a third degree of vulnerability, and further comprising a third group of retroreflectors mounted to the third target area, the third group of retroreflectors arranged in a third pattern visually distinguishable from the first and second patterns.
Claim 8
Dependent Claim
34 words
The system of claim 6 wherein said first pattern includes a single retroreflector, said second pattern includes two closely horizontally spaced retroreflectors, and said third pattern includes three retroreflectors in a closely spaced triangle.
Claim 9
Dependent Claim
24 words
The system of claim 6 wherein the third visually distinguishable pattern comprises the retroreflectors mounted to the third target area with a third density.
Claim 10
Dependent Claim
39 words
The system of claim 1 wherein the electromagnetic beam is a laser beam and the optical system includes a laser beam source for producing the laser beam and directing the laser beam through a lens system towards the target.
Claim 11
Dependent Claim
44 words
The system of claim 1 wherein the electromagnetic beam has a chosen cross-sectional size at the target, and further comprising a distance compensating optical system for maintaining said chosen cross-sectional size constant irrespective of the distance between the target and the optical aiming system.
Claim 12
Dependent Claim
15 words
The system of claim 10 wherein the distance compensating optical system includes a range finder.
Claim 13
Dependent Claim
29 words
The system of claim 1 further comprising means for adjusting the direction of the electromagnetic beam for lead values required for compensation when the target is a moving target.
Claim 14
Dependent Claim
37 words
The system of claim 1 wherein the firearm includes a ballistic projectile, the ballistic projectile having a ballistic trajectory, and further comprising means for adjusting the direction of the light beam to compensate for the ballistic trajectory.
Claim 15
Dependent Claim
34 words
The system of claim 1 wherein each said group of retroreflectors has a different number of retroreflectors, the number of retroreflectors for each group defining the degree of vulnerability for the respective target area.
Claim 16
Independent Claim
102 words
A system for practicing aiming a firearm at a target comprising: a target having first and second target areas with first and second degrees vulnerability, respectively; first and second groups of retroreflectors mounted to the first and second target areas, respectively, the first and second groups of retroreflectors arranged in first and second visually distinguishable patterns, respectively; an optical aiming system for directing an electromagnetic beam at the target and for receiving electromagnetic radiation reflected back from one of the groups of retroreflectors; and a charge coupled device type camera for electronically detecting the pattern of retroreflectors illuminated by the electromagnetic beam.
Claim 17
Independent Claim
102 words
A system for practicing aiming a firearm at a target comprising: a target having first and second target areas with first and second degrees vulnerability, respectively; first and second groups of retroreflectors mounted to the first and second target areas, respectively, the first and second groups of retroreflectors arranged in first and second visually distinguishable patterns, respectively; an optical aiming system for directing an electromagnetic beam at the target and for receiving electromagnetic radiation reflected back from one of the groups of retroreflectors; and a charge coupled device type camera for electronically detecting the pattern of retroreflectors illuminated by the electromagnetic beam.
