The patent proposes a system where an external device monitors the area for incoming projectiles. If it detects a projectile headed near a person hooked into the system it can either shock their muscles in order to move their body a particular way to dodge the bullet, Neo style, or it could simply make the intended target collapse.
BM indeed has filed a patent to this effect. Patent #7484451 to be exact.
A method of protecting a target from a projectile propelled from a firearm comprises detecting an approaching 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. The projectile may be detected in the detecting step 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.
Will it work? Who knows. What I do know is I would rather address a lethal threat with the appropriate level of lethal force. Preferably before I need to dodge a bullet.
