Abstract

The individual surveillance system for rapid detection of accidents is designed for the driver of machines in the mineral extraction industry. The system has a timer connected to an electrical energy source. The timer produces after a predetermined time interval determined from its period of actuation, a first control signal. This signal is applied to a light or sound signal transmitter. This transmitter being designed to attract attention or aid to the person to be protected. The system has means which are actuated manually by the protected person to cancel the request for aid by resetting the timer to zero. A high power sound signal is transmitted from a transmitter on reception of a second signal from the timer. This second signal following a certain time after the first. This second signal is only transmitted if the person protected has not cancelled the system before the interval between signals.
