A personal ballistic protective device having a first layer comprised of ballistic material and a second layer comprised of buoyant material. The second layer preferably has a density sufficient to counteract a density of at least the first layer of ballistic material such that the first layer and the second layer have a combined density substantially equal to or less than the density of water. A method of counteracting negative buoyancy in a personal protective device is also disclosed.

A ceramic armor system with built-in conductive circuit attached to a ceramic component. The conductive circuit can be accessed by a user at contacts provided in the system. The circuit is arranged so that damage such as cracks that occurs within the ceramic component can propagate into the conductive material forming the circuit and thereby cause a rupture in the conductive circuit. An electrical probe such as an ohmmeter is used to measure the conductive circuit resistance that is then checked against an expected value. The results are used to determine if the ceramic armor component is in operable condition.
