Abstract: A multi-chambered torque personal flotation device for corrective turning action of a weighted individual. The multi-chambered device is capable of being adjusted to provide a wide range of buoyancy as might be needed under differing degrees of ballistic protection. An eccentric mobile buoyant system complements a massive displacement required to float the armored victim by providing the energy required to reliably initiate corrective turning action, regardless of the gear worn, position of water entry, or state of consciousness of the wearer. In the event the conscious victim desires to shed the body armor, a series of quick release members allow the victim to shed their ballistics vest while retaining their life jacket. The integrated life jacket upon separation from the heavily ballasted body armor continues to provide reliable airway protection.

Abstract: A self-locking hinge apparatus with a single stable state includes a pivotal shaft, a retaining ring, a stator, a compression spring, and a rotor. The retaining ring, the compression spring, the stator and the rotor are arranged in series along the pivotal shaft. The stator is slide-able but not rotatable on the pivotal shaft. The rotor is both slide-able and rotatable on the pivotal shaft. By providing the compression spring to enforce a cam-contact between the stator and the rotor, an auto cam sliding pair is then formed to make the hinge apparatus stabilized automatically at the predetermined stable state.
