Patents filed by an Israeli inventor Amit Weisman and US company Yardeni Associates
of Connecticut make scary reading for nervous travellers.
Airport security guards already use hand-held electromagnetic wands to detect
metal hidden under clothing. The same wand can also sniff for traces of the
gases some explosives emit into the air.
If the passenger is a suicide bomber who realises the wand has found something,
the guard might not have enough time to pull out handcuffs or a gun. So the
new wand will have a hidden secret – a transformer which steps the detector’s
battery power up to 100 kilovolts and feeds it to disguised metal electrodes
at the end of the wand.
If the wand gives a silent warning of explosives, the guard can then subtly
slide the pads onto the passenger’s neck or hands and press a shock button.
The patent reassures that the effect is “temporary and reversible”.
So an innocent traveller who “happened to have a significant amount of
metal on his person or happened to treat explosives legally” should wake
up shaken but unharmed.
