## Abstract

Dual mode apparatus for assisting in the aiming of a firearm including laser designating apparatus boresighted with the barrel of the firearm, apparatus for actuating the laser designating apparatus in a first mode of operation for illuminating an impingement location on a target while permitting normal operation of the firearm to shoot projectiles and apparatus for actuating the laser designating apparatus in a second mode of operation to illuminate an impingement location on a target with laser light in response to actuation of the trigger of the firearm.

## Claims

### Claim 1

Dual mode apparatus for assisting in the aiming of a firearm comprising:
laser designating means boresighted with the barrel of the firearm;
means for actuating the laser designating means in a first mode of operation for target designation to illuminate a target while permitting normal operation of the firearm to shoot projectiles and including an operator control switch whose actuation produces a laser output of the laser designating means; and
means for actuating the laser designating means in a second mode of operation for target practice to illuminate a target with a laser beam emission in response to actuation of the trigger of the firearm and incorporating a firing sensor whose output produces a laser beam simulated firing.

### Claim 2

A target practice system comprising:
laser designating means boresighted with the barrel of the firearm;
means for actuating the laser designating means to illuminate a target with laser light at an impingement location in response to actuation of the trigger of the firearm;
target means defining a target reference and including sensor means for sensing the spatial relationship between the impingement location and the target reference, said target means including:
a laser light diffuser which produces scattering of incoming laser light in a known geometrical distribution; and
a plurality of detectors for sampling said distribution and thus providing an output indication of the position of said impingement location relative to said target reference; and
means for providing a hard copy output indication of the spatial relationship between the impingement location and the target reference.

### Claim 3 (depends on 2)

A system according to claim 2 and wherein said laser designating means includes dual mode laser designating means and also includes:
means for actuating the laser designating means in an actual firing mode of operation for illuminating a target while permitting normal operation of the firearm to shoot projectiles.

### Claim 4

A target practice system comprising:
laser designating means boresighted with the barrel of the firearm;
means for actuating the laser designating means in a first mode of operation for target designation to illuminate a target while permitting normal operation of the firearm to shoot projectiles and including operator control switch whose actuation produces a laser output of the laser designating means;
means for actuating the laser designating means in a second mode of operation for target practice to illuminate a target with a laser beam emission in response to actuation of the trigger of the firearm and incorporation a firing sensor whose output produces a laser beam simulated firing; and
target means defining a target reference and including sensor means for sensing the spatial relationship between the impingement location and the target reference, said target means including:
a laser light diffuser which produces scattering of incoming laser light in a known geometrical distribution; and
a plurality of detectors for sampling said distribution and thus providing an output indication of the position of said impingement location relative to said target reference; and
means for providing a hard copy output indication of the spatial relationship between the impingement location and the target reference.

### Claim 5

A target practice system comprising:
laser designating means boresighted with the barrel of the firearm;
means for actuating the laser designating means to illuminate an impingement location on a target with laser light in response to actuation of the trigger of the firearm; and
target means defining a target reference and including sensor means for sensing the spatial relationship between the impingement location and the target reference, the target means comprising a laser light diffuser for scattering received laser light and said sensor means being operative for sensing the spatial distribution of the scattered received laser light.

### Claim 6 (depends on 4)

A target practice system according to claim 4 and also comprising means for providing a hard copy output of the spatial relationship between the impingement location and the target reference.

### Claim 7 (depends on 5)

A target practice system according to claim 5 and also comprising means for providing a hard copy output of the spatial relationship between the impingement location and the target reference.
