While the shrapnel created by a roadside bomb or improvised explosive device is lethal all on its own, the concussive force of a blast can seriously injure, incapacitate and kill the crew of a vehicle right through its armor.
To combat the effect of blast waves, a company called Survival Consultants International has developed a wall of airbags triggered by a light sensor. Light, the company maintains, is the only thing faster than a concussive wave caused by an explosion. In a split second, the triggered sensors confer with an on-board processor on whether or not to deploy the bags, which in turn combat the force of a blast wave.
