Abstract:
This invention relates to a breathing sensing device for detecting a pressure drop due to breathing. The device includes a diaphragm (100) having a first pressure chamber (120) on one side and a second pressure chamber (121) on a second side within an actuator housing. The first and second pressure chambers (120,121) are connected to a system pressure (L1) by flow passages (143, 153) having different cross sectional passage area (Ar, Af) arranged to facilitate detection of a pressure drop due to breathing.
Abstract:
The present invention relates to a safety method in connection with SCUBA diving to control a diver's buoyancy, in which method the diver (11) is equipped with diving equipment comprising at least one air pressure tank (1), a valve device (2) connected to the pressure tank (1) and arranged to supply air from said pressure tank via first supply means (5) to a breathing regulator (4) and via second supply means (7, 9, 12) to an inflatable diving jacket (6) in order to control the diver's buoyancy, an actuator (8) being able to automatically initiate inflation of the diving jacket (6) when the diver has not affected the air flow through the breathing regulator (4) for a certain time period, said actuator (8) being controlled by an actuation mechanism (20) that automatically sets the actuator in active mode when the diver is within an actuation zone (A), wherein in order additionally to improve the diver's buoyancy the actuator (8) is also arranged to automatically initiate dumping of a weight (11) carried by the diver when the air flow through the breathing regulator (4) has ceased for a certain time period. The invention also comprises a safety device, an inflatable diving jacket and an inflator.
