An armor component having a plurality of ceramic elements, where each ceramic element is covered by a metal coating. Each metal coating covers the outer surface of only one ceramic element. The metal coating is configured to increase a dwell time for the armor component when the armor component is impacted by a projectile.

A landmine, unexploded ordnance (UEO) or improvised explosive device (IED) detection and destruction system which uses ground penetrating (GPR) radar to detect and guide a ballistic weapon to destroy it. The positions of which are also visually communicated through smart helmets or headgear having heads up display visors worn by the personnel, soldiers, combatants or any endangered persons in the vicinity.

According to the invention there is provided a fibrous armor material for dissipating the kinetic energy of a moving object which is impregnated with a shear thickening fluid, in which the shear thickening fluid includes particles of a thickening agent suspended in a liquid, and the volume fraction of the thickening agent in the shear thickening fluid is selected so that the shear thickening fluid has a viscosity-shear stress characteristic substantially corresponding to curve B or lying between curve B and curve D as shown in FIG. 2.

A rigid ballistic-resistant composite includes large denier per filament (dpf) yarns. The yarns are held in place by a resin to form a rigid composite panel with improved ballistic performance. The large dpf yarns may be selected from aromatic heterocyclic co-polyamide fibers, polyester-polyarylate fibers, high modulus polypropylene (HMPP) fibers, ultra high molecular weight polyethylene (UHMWPE) fibers, poly(p-phenylene-2,6-benzobisoxazole) (PBO) fibers, poly-diimidazo pyridinylene (dihydroxy) phenylene (PIPD) fibers, carbon fibers, and polyolefin fibers.

A two wheeled throwable robot comprises an elongate chassis with two ends, a motor at each end, drive wheels connected to the motors, and a tail extending from the elongate chassis. The throwable robot includes a pair of torque limiting mechanisms, each torque limiting mechanism being operatively coupled between a motor and a drive wheel. Each torque limiting mechanism comprises a drive flange portion, a driven flange portion and a plurality of rollers. A spring element provides a ring force that biases the rollers toward the driven flange portion.

An unmanned following vehicle includes a controller that controls the unmanned following vehicle to move in parallel with a moving object by following the moving object on a left side or a right side of the moving object. For example, the controller adjusts a moving speed of the unmanned following vehicle according to a Y-axis coordinate difference value, which is a difference value between a position of the moving object and a position of the unmanned following vehicle in a forward direction. The controller also adjusts a steering direction and a steering angle of the unmanned following vehicle according to an X-axis coordinate difference value, which is a difference value between the position of the moving object and the position of the unmanned following vehicle in a lateral direction.

Embodiments of the invention relate to a drive system for armored electric vehicles and a method for its operation in event of a fire of the traction battery.
