Abstract

A device worn by a first diver provides a warning of conditions of danger and/or emergency to a second diver positioned at a distance from the first diver. The device includes a device for detecting the pressure in the compressed-air tanks, a device for transducing the detected datum, and a device for indicating the aforesaid datum.

Claims

1. Device for giving warning of conditions of danger for scuba diving comprising means of detection of the pressure in compressed-air tanks, means of transducing datum detected, and means of indicating the datum in a manner such that when the device is worn by a first scuba diver the datum is easily detected by a second scuba diver positioned at a distance from the first scuba diver.

2. Device according to claim 1 wherein said means of detection are connected to a high-pressure output of a first reducer stage of the two-stage breathing apparatus.

3. Device according to claim 2 wherein said means of detection include a pressure sensor, and said transducing means include a circuit that converts the pressure detected into a pulse and a circuit that transmits it to a warning means, said means of warning including LEDs of different colours arranged on a control panel of a computer for scuba diving.

4. Device according to claim 2 wherein said means of detection include an analogue or digital pressure gauge, the transducing means comprise an electrical circuit which transmits the datum to said means of warning including LEDs of different colours arranged on said pressure gauge.
