Self calibrating weapon shot counter

Abstract

A microcontroller operated module is affixed to a fire arm. The module includes an accelerometer for measuring the G force of each round fired by the firearm, a flash memory (non-volatile memory) for storing the shot profile data that includes shot count and recoil data and transmitting it to a remote location such as a remote computer via a serial communication device pursuant to RS232 standard, Bluetooth, awave or other low power RF transmitter. The module including a wake up circuit adapted to switch upon detection of a fired shot to signal said microcontroller to initialize a low power mode to activate said MEMS accelerometer faster than said accelerometer would activate by itself.

1 . A shot device for recording and transmitting shot profile data of shots fired from a fire arm, comprising:
 a microcontroller operated module affixed to a fire arm, said module comprising a MEMS accelerometer for measuring the G force of each round fired by the firearm, a non volatile memory for storing the shot profile data that includes shot count and recoil data a serial communication device for transmitting said stored shot profile data to a remote location via an RF signal.   
   
   
       2 . A shot device for recording and transmitting shot profile data of shots fired from a fire arm, comprising:
 a microcontroller operated module affixed to a fire arm; said module comprising a MEMS accelerometer for measuring the G force of each round fired by the firearm, a non volatile memory for storing the shot profile data that includes shot count and recoil data a serial communication device for transmitting said stored shot profile data to a remote location via an RF signal; and   a wake up circuit adapted to switch upon detection of a fired shot to signal said microcontroller to initialize a low power mode to activate said MEMS accelerometer faster than said accelerometer would activate by itself.   
   
   
       3 . The device according to  claim 1  wherein said wake up circuit is a normally closed G switch.
