Abstract: This invention is a portable pneumatically driven pressure intensifying positive displacement hydraulic power unit that can be transported in a bag or backpack and carried or worn by the user. The device can be powered by any suitable high pressure gas that is preferably contained in a small pressure vessel for portability. The device can be used to supply high pressure hydraulic fluid to tools with a wide range of uses in many fields including construction, industrial, breaching, and emergency service situations. This novel device does not require an electric or fuel powered hydraulic fluid pumping system, which allows it to be very portable and used in almost any environment (e.g., hazardous atmosphere or under water) without being tethered to an electric or fuel powered power source.

Abstract: A light weight armor system for retrofitting onto a light vehicles or incorporating into a vehicle to protect against HEAT warheads. The armor system comprises an outer armor structure for rotating a HEAT warhead toward a preferred detonation angle to maximize the protection of underlying armor or vehicle structures. This first armor structure will further impart a rotational movement to increase the energy impact footprint, dissipate jet stream energy, and improve the probability that a second protection layer can successfully resist penetration by the jet stream. Coatings on the armor structure materials laterally impact a HEAT jet stream to further disrupt the jet and dissipate its energy.
