Abstract:
1. A method of transferring data in a projectile launching device, comprising the steps of: providing a projectile launching device having a breech for receiving a projectile therein for launch; providing a first optical transmitter, having a range, interconnected to the projectile launching device and residing in the breech; providing a first optical receiver interconnected to the projectile launching device and residing in the breech; providing an external device in proximity to the projectile launching device; providing a second optical transmitter, having a range, interconnected to the external device; providing a second optical receiver interconnected to the external device; sending data from the first optical transmitter to the second optical receiver; sending data from the second optical transmitter to first optical receiver; whereby the projectile launching device optically communicates with and optically exchanges data over the air with the external device and the first optical transmitter and first optical receiver are configured to optically communicate directly with each other over the air for detecting presence of a projectile in the breech.
