AUTOMATIC FLOW CONTROL (AFC) pat. #5,678,541
Atomic Aquatics has developed the first and only automatic flow control that
automatically changes the breathing characteristics with depth. At depth, the air
density increases (gets thicker) and it becomes harder to move through the regulator.
The result is increased breathing effort at depth. Many regulators have different types of
devices to increase flow (venturi) but these are either fixed in place or manually set and
