Bionic Bullet Dodging Armor?

Straight out of science fiction, IBM filed a patent on body armor that will use electrical impulses to make a person get out of the way of bullets. It's a pretty crazy idea, but wow. It's hard for us to really understand how slow bullets are since they are typically used at fairly short range. The example of a 2.5 km shot taking 4 seconds to reach its target definitely shows that this could be possible if the armor could detect a tiny projectile at a long enough range.
