The invention concerns an individual protective device comprising at least one glove (20), a garment or a protective accessory equipped with electronic sensors and/or circuits (22) transmitting coded monitoring signals, electrically connected to an array or a network of distributed antennae. The whole assembly is mounted on perfectly flexible printed circuits, and adapted sensors are provided for verifying whether the protective device is being worn. A first detector is mounted on a dangerous machine to be protected, and picks up a signal transmitted by radio channel, so as to stop the machine and trigger an alarm signal if a part of the body, in particular the hand, penetrates into the tool travel range. A second detector is housed in a reading zone for controlling the permanent transmission of coded signals coming from the device. The coded signal transmission can be inhibited if the access code acquired by the operator on the machine keyboard does not match. The operator must be protected against electrical, radioactive or thermal risks, and in such a case the device comprises distributed sensors which analyse the electric fields, the radioactivity or the heat flux, and trigger off various alert levels. Moreover, even if the stoppage or reaction time may exceed the endangering times, a screen is made to intervene between the operator and the danger. |
