Method and device for automatic buoyancy compensation for a scuba diver or underwater device while in any orientation

摘要: A buoyancy compensation device and method for a scuba diver or other underwater object, which decreases by actively pumping air from flexible bladder while the object is in any orientation, said having internally manifold assembly providing access to pockets of anywhere within bladder. In addition, may be adapted automatically diving, surfacing, maintaining predetermined water depth orientation diver's object's changes, including sensor measuring depth, one more control inputs selecting controller unit that determines descent rate, ascent maintenance selected based on monitoring setting inputs, objects previous habits behavior.
