  • Description

    An executive in a Sydney electronics firm has perfected what he believes to be a foolproof system for foiling aerial hijackers and bank robbers. The device, still unnamed but patented in 20 countries, employs a highly selective sensor said to be able to differentiate between guns and such inoffensive metal objects as keys, coins, or even toy guns.

    The principle of the device is demonstrated by the inventor himself Mr. Yull Brown, using a model one seventh the size of the actual invention. Three sensing coils are built into the walls of a revolving door support and they put the objects inside through a three-way identification process. The device picks out the mass, surface shape and metal quality of the object. This makes it possible to distinguish between various objects and even differentiate between real and toy guns.

    The Senor is linked to a bulletproof entry compartment through which all passengers or bank customers must pass. If a gun is detected, the compartment doors automatically lock trapping the gun carrier in the cubicle, and an alarm sounds.

    The suspect is then instructed by loudspeaker to deposit his gun in a chute in the wall of the compartment. Should he refuse, a harmless gas is released putting him to sleep until he has been disarmed.

    The sensing panel, containing all the electronic equipment, can be varied in sensitivity so as to detect such things as very small knives, but its primary task is to detect heavy-metal weapons such as grenades and revolvers.

    The inventor has installed the machine with a ratchet deice on top of the doors which prevents the doors from being reversed, and a speed control to govern the rate at which people pass through.

    Mr. Brown says the protective system can be installed in an aircraft or a bank of about 4,000 dollars (GBP 1,600 sterling) per entrance.
