Abstract:

A firearm maintenance system wherein a count for the number of times the firearm is fired is kept and stored in memory that is resident on the firearm. Also installed on the firearm are a shot counter device, including an inertia switch, a communication card, and an extended life battery. An epoxy resin encases the memory, shot counter device, communication card and battery to protect them from detrimental environmental effects. The life of various component parts of the weapon are tracked against the shot count of the weapon and replaced at appropriate intervals. Weapon maintenance is performed by transferring the weapon's data from the weapon's memory to an operator laptop computer wherein an algorithm analyzes the data and advises the operator to take necessary maintenance steps, such as replacing parts that have reached the end of their useful life. After performing such necessary maintenance, the operator makes a maintenance data submission that updates the memory to reflect the maintenance data steps taken. Data is transferred between the weapon and laptop computer via infrared communication such that no electrical connection to the weapon mounted device is necessary to communicate data into or out of the device.
