The defense exhibition in Austin was rather small-scale, with the participating manufacturers catering more to the needs of the local Texans, offering a complete array of personal defense weapons, but high-tech individual soldier gear was rarely seen.
At the booth of a family technology company, Joe Ga discovered a shock sensor the size of a coin and a set of diving equipment.
The shock sensor, attached to the helmet and tactical vest, could monitor how much explosive force the human body had endured.
There were three levels, with level one being a minor shock one could grit teeth and carry on with.
Level two indicated moderate injury, where one wouldn't last long and needed to evacuate quickly.
Level three was severe injury, where without treatment, death would ensue.
The Americans, all too familiar with war, knew well that it was not bullets but bomb shrapnel and blasts that caused the most fatalities on the battlefield, which is why they developed such a device.
