<p>The safety device for a person staying within a non atmospheric pressurized medium, particularly for divers, operates regardless of the pressure conditions and ensures that emergency measures be taken when the person is in danger of fainting. This is provided by a monitoring device controlled by a pressure sensor and by a cancelling device. The monitoring device generates a series of monitoring signals together with emergency signals cancellable by the person by actuating the cancelling device. To this effect the time interval between the monitoring signals is automatically adjustable as a function of the ambiant medium pressure measured by the pressure sensor. </p> |
