Weapons System Smart Device

Abstract

A weapons system comprises a firearm, one or more sensors on an interior or exterior portion of the firearm configured to detect a motion or location of a moving part of the firearm relative to the sensor, a microprocessor configured to detect a signal sent by the one or more sensors and determine a status of the firearm, and a display in communication with the microprocessor configured to display information relating to the status of the firearm.

What is claimed is: 
     
         1 . A weapons system, comprising:
 a firearm;   one or more sensors on an interior or exterior portion of the firearm configured to detect a motion or location of a moving part of the firearm relative to the sensor;   a microprocessor configured to detect a signal sent by the one or more sensors and determine a status of the firearm; and   a display in communication with the microprocessor configured to display information relating to the status of the firearm.   
     
     
         2 . The weapons system of  claim 1 , wherein the microprocessor is configured to increment a counter. 
     
     
         3 . The weapons system of  claim 2 , wherein the counter represents a number of instances the firearm has been discharged. 
     
     
         4 . The weapons system of  claim 1 , wherein the one or more sensors includes a Hall effect sensor. 
     
     
         5 . The weapons system of  claim 1 , wherein the one or more sensors includes a reed switch. 
     
     
         6 . The weapons system of  claim 1 , further comprising a global positioning system or an inertial navigation system to track the location or motion of the firearm. 
     
     
         7 . The weapons system of  claim 1 , wherein the moving part of the firearm is a bolt carrier, and the microprocessor determines that a signal sent from the one or more sensors represents the discharging of an ammunition round and shell casing from the firearm. 
     
     
         8 . The weapons system of  claim 7 , wherein the moving part of the firearm is a follower that moves in a magazine of the firearm as ammunition rounds are added to or removed from the magazine, the one or more sensors are coupled to the magazine and detect a position of the follower. 
     
     
         9 . The weapons system of  claim 8 , wherein at least one of the one or more sensors comprises multiple portions coupled to the magazine and a single portion coupled to the follower that aligns with one of the portions of the sensors coupled to the magazine. 
     
     
         10 . The weapons system of  claim 8 , wherein the microprocessor detects a position of the follower within the magazine and determines a number ammunition rounds present in the magazine. 
     
     
         11 . The weapons system of  claim 1 , wherein the microprocessor is configured to determine a number of ammunition rounds remaining in a magazine residing in the firearm. 
     
     
         12 . The weapons system of  claim 1 , wherein the display is configured to show a number of instances the firearm has been discharged. 
     
     
         13 . The weapons system of  claim 1 , wherein the display is configured to present a location and a heading of the firearm. 
     
     
         14 . The weapons system of  claim 13 , wherein the display is configured to present an alert when an undesired location and heading is detected. 
     
     
         15 . The weapons system of  claim 1 , wherein the display is part of a smart phone or tablet located external to the firearm. 
     
     
         16 . The weapons system of  claim 1 , wherein the display is attachable to the firearm. 
     
     
         17 . The weapons system of  claim 1 , wherein the moving part of the firearm is a bolt carrier group. 
     
     
         18 . The weapons system of  claim 1 , comprising a magnet located on the moving part of the firearm that triggers the sensor when the magnet and sensor are in proximity. 
     
     
         19 . A device for use with a firearm, the device comprising:
 a computing device for receiving signals representative of a location or movement of a moving part of a firearm during discharge of an ammunition round; and   wherein the computing device is configured to determine a count of a number of instances that the firearm has been discharged from the received signals and to communicate the determined count to a display.   
     
     
         20 . The device of  claim 19 , wherein the display is part of a smart phone or tablet located external to the firearm. 
     
     
         21 . The device of  claim 19 , wherein the display is attached to the firearm. 
     
     
         22 . The device of  claim 19 , wherein the computing device receives the signals from one or more sensors attached to the firearm. 
     
     
         23 . A computing device-implemented method comprising:
 receiving signals representative of a location or movement of a moving part of a firearm during discharge of an ammunition round;   producing a count of a number of instances that the firearm has been discharged from the received signals; and   presenting the determined count on a display of the firearm.   
     
     
         24 . One or more computer readable media storing instructions that are executable by a processing device, and upon such execution cause the processing device to perform operations comprising:
 receiving signals representative of a location or movement of a moving part of a firearm during discharge of an ammunition round;   producing a count of a number of instances that the firearm has been discharged from the received signals; and   presenting the determined count on a display of the firearm.
