摘要
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.
