Flotation devices

The Flotation device, or air bladder is a tool that allows the user to reach the surface of a liquid environment faster than by simply swimming to the surface.
== Overview ==
The flotation device is a safety device for divers which electronically monitors the diver’s breathing, alerts the diver and its teammates if abnormal breathing occurs, and automatically adds air to their buoyancy compensator and brings them to the surface if they become unconscious while underwater. 
The flotation device works by controlling a divers buoyancy automatically. 
=== Usage ===
Buoyancy control underwater is vitally important, and works by adding air to the buoyancy compensator to become more buoyant; add weight or remove air from the buoyancy compensator to become negatively buoyant and sink. In case a diver becomes unconscious underwater and unable to use the buoyancy to ascend to the surface the flotation device activates. 
=== Mecanics ===
The flotation device replaces the inflator unit on a buoyancy control device and has an oral and power inflation valve built in, and while diving provides the same function as a regular inflator unit. Inside the unit is a microprocessor which monitors the diver’s breathing rate (or lack of breathing), and if the diver’s breathing becomes irregular, it sounds an audible alarm and flashes a small strobe which is mounted on the unit. If a diver stops breathing completely for 30 seconds, the flotation device automatically adds air to the buoyancy control device, which brings the diver to the surface.
=== Variations ===
Another version of the system detects when the diver has less than thirty seconds of oxygen left and activates.
