Abstract

The system uses a miniature transmitter-receiver (1) which can be fitted into the side frames of a pair of spectacles. The transmitter receiver (1) receives a message transmitted by the employee who is wearing the spectacles carrying the transmitter receiver (1). The message is made by the employee clashing his teeth according to a chosen code. Reception of these light shocks by the transmitter receiver (1) is made through jawbone. A similar results may be obtained with the transmitter receiver in a finger ring. The received message is transmitted to a master computer. The coded message indicates the place of aggression, the number of aggressions, the name, colour and type of their means of getaway and also the direction in which it is thought they are going.
