Abstract

An automatic buoyancy control device suitable for free-swimming divers comprises a bladder 1, electro-pneumatic valves 2, 20 and 21 and a processing unit. The electro-pneumatic valves are controlled to inject gas into or vent gas from the bladder in response to control from the processing unit. The processing unit uses ambient pressure to calculate the relative buoyancy of a diver using the device and controls the electro-pneumatic valves accordingly. The device may enable a controlled ascent rate, controlled descent rates, the imposition of a maximum depth limit, the facility to hold a set depth and the facility to follow a dive profile or decompression profile for the user. The device provides a high safe failure fraction.
