VELOCITY, INTERNAL BALLISTICS AND EXTERNAL BALLISTICS DETECTION AND CONTROL FOR PROJECTILE DEVICES AND A REDUCTION IN DEVICE RELATED POLLUTION
First Claim
1. A compressed-gas projectile launcher comprising:
- a valve system adapted to release a gas into a firing chamber containing a projectile and to maintain the gas at a predetermined pressure until the projectile leaves the launcher.

Abstract
Improvements to projectile devices (particularly air guns) include techniques for measuring and controlling the velocity of projectiles in the barrel and after leaving the barrel, allowing the use of non-toxic projectiles. Tracking of a projectile'"'"'s flight by its unique sound and/or its unique electromagnetic signal or signal modulation are also provided, along with after-barrel guidance that can be used to improve accuracy. Control for discriminating between authorized and unauthorized users is also provided. A projectile device can also be used for inexpensive and harmless practice using optical and/or acoustic information gathered by targeting and imaging systems built into the device.
