Patent ID: 7484451

Claim:
A method of protecting a target from a projectile propelled from a firearm comprising: detecting an approaching projectile propelled from a firearm, wherein the projectile is detected by emitting an electromagnetic wave from a projectile detector and receiving the electromagnetic wave after the electromagnetic wave has been reflected back toward the projectile detector by the projectile; continuously monitoring the projectile and transmitting an actual position of the projectile to a controller; computing an estimated projectile trajectory based upon the actual position of the projectile; determining an actual position of a target with a plurality of position sensors and a plurality of attitude sensors; determining whether the estimated projectile trajectory coincides with the actual position of the target; and triggering a plurality of muscle stimulators operably coupled to the controller and to the target when the estimated projectile trajectory coincides with the actual position of the target, wherein the muscle stimulators stimulate the target to move in a predefined manner, and wherein the target moves by an amount sufficient to avoid any contact with the approaching projectile.
