Laser shooting system

Abstract

A firearm training system has a plurality of guns each having a memory having a long-code register holding a predetermined gun-specific long code and a short-code register. The gun also has a generator of random short codes. A switch means connected between random short-code generator and the short-code register is actuatable for loading a new short code into the short-code register. The guns also has a laser and circuitry connected to the memory for encoding the laser's beam with the long and short codes from the respective registers. The target has a data-holding memory, a laser-beam sensor, and a processor connected to the sensor and to the memory for reading codes of laser beams detected by the sensor and for associating the read codes with data in the memory.

1 . A firearm training system comprising: 
 a plurality of guns each having 
 a memory having a long-code register holding a predetermined gun-specific long code and a short-code register,  
 means for generating random short codes,  
 switch means connected between the means for generating and the short-code register and actuatable for loading a new short code into the short-code register,  
 means for generating a laser beam, and  
 means connected to the memory for encoding the beam with the long and short codes from the respective registers; and  
   a target having 
 a data-holding memory,  
 a laser-beam sensor, and  
 means connected to the sensor and to the memory for reading codes of laser beams detected by the sensor and for associating the read codes with data in the memory.  
   
   
   
       2 . The shooting system defined in  claim 1  wherein the means for encoding is operable to alternately encode the laser beam with the long code or the short code from the short-code register.  
   
   
       3 . The shooting system defined in  claim 1  wherein the target has means for displaying the short code.  
   
   
       4 . The shooting system defined in  claim 3  wherein the target has a memory holding shooter data and means connected to the display for associating the shooter data with the short code and displaying the associated data and short code.  
   
   
       5 . The shooting system defined in  claim 3  wherein the target has input means for feeding the shooter data into the target memory.  
   
   
       6 . The shooting system defined in  claim 1  wherein the coding means codes the laser beam with pulse sequences representing the codes.  
   
   
       7 . The shooting system defined in  claim 6  wherein the pulse sequences include pulses of different lengths.  
   
   
       8 . The shooting system defined in  claim 1  wherein the coding means codes the laser beam by varying its frequency.
