Abstract: An underwater motive device provides an integrated and modular battery and motive housing which is carried within an outer housing and secured by a nose cone system. The nose cone system works against an “o” ring seal carried between a structure of the integrated and modular battery and motive housing and the outer housing. A pair of latches act as levers to forcibly push the nose cone in place to seal off the battery compartment, and with cam action when used to urge the nose cone to a disengaged position with respect to the “o” ring seal. Nose cone removal and re-sealing procedure can be accomplished easily, even by those of limited strength.

Abstract: A light generating flashlight system device utilizes a large centrally located magnet which is mounted to slide past a magnet pickup or current induction wire which may be preferably mounted at a center point of travel in a tubular housing having a tubular chamber through which the magnet travels. A pair of elastomeric dampers are located each at the end of a support system sleeve which is sized to fit within a main housing to stabilize all internal support within a sealed unit. The result is a device which both facilitates the manual movement of the flashlight body so that the magnet slides past the center magnet pickup or current induction wire, and also conserves the residual momentum of the magnet once it has traveled past the magnet pickup or current induction wire by providing a bumper and spring to conserve some of the mechanical energy going in the other direction. Ninety second of manual activation enables about five minutes of illumination.
