Unidirectional transparent projectile penetration resistant panels and bidirectional opaque projectile penetration resistant assemblies and systems and methods of forming and mounting the same relative to underlying support structures.

A two wheeled robot with a pair of motorized wheels mounted on each end of a body and a rearwardly extending tail. The body comprising a chassis with sides and exterior side surfaces and providing an accessory mounting interface. The interface having a matrixical arrangement of threaded holes and one or more landings, the landings having an outwardly facing planar landing surface with hole openings at the landing surface. An accessory with a robot mounting interface cooperates with the chassis at the accessory mounting interface such that prior to fastening the accessory has a single degree of freedom of movement. Screws extend through portions of the accessory into select ones of the threaded holes of the matrixical arrangement.

The exemplary arrangement relates to a target comprising at least one dummy depicting at least one part of the human body. According to the exemplary arrangement it is provided, that the dummy depicting at least one part of the human body comprises a plurality of sensors, which communicate with a sensor data evaluating apparatus (140) for the registration of the sensors. The sensor data evaluating apparatus determines, by mathematical correlation of points in time (t.sub.1, t.sub.2, t.sub.3) corresponding to points of maximum pressure (Pmax.sub.1, Pmax.sub.2, Pmax.sub.3) from sensor data of the plurality of sensors the point of entry ({right arrow over (T)}) and preferentially the trajectory of a projectile penetrating the dummy.

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.

The present disclosure is directed to mobile correctional facility robots and systems and methods for coordinating mobile correctional facility robots to perform various tasks in a correctional facility. The mobile correctional facility robots can be used to perform many of the tasks traditionally assigned to correctional facility guards to help reduce the number of guards needed in any given correctional facility. When cooperation is employed among multiple mobile correctional facility robots to execute tasks, a central controller can be used to coordinate the efforts of the multiple robots to improve the performance of the overall system of robots as compared to the performance of the robots when working in uncoordinated effort to execute the tasks.

Provided is a telerobotic mining device for underground mining, and specifically for stope mining, as well as a method of mining using such a device. The telerobitic mining device is capable of remotely moving about a mine and utilizing drill arms to drill a hole within a chosen rock bed. Explosive placement arms on the telerobot may be utilized to place an explosive within the drilled hole to blast away rock. Control over the device is achieved by way of operational commands that may be wirelessly sent to the device from a command center located outside the mine.

A defense mobile device for securing a door during shelter-in-place situations. The device includes wheels rendering it mobile and stops that, when actuated, hold the device stationary. A panel has a ballistic core that resists bullets, a front face, an opening, and a cover positioned over the opening to overlay and enclose a door knob protruding through the opening. The front face forms, or has affixed to it, a writing surface. The panel pivots between a plurality of angled positions to facilitate writing and an upright position flat against the door. A locking rod, rotatably connected to the panel, pushes and pulls the panel between its angled positions and its upright position. A lever-locking mechanism or a twist-lock mechanism secures the device in place against or within a door frame and against the door.

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.

Antiballistic armour plate includes a ceramic body including a hard material, provided, on its inner face, with a back energy-dissipating coating. The ceramic body is monolithic. The constituent material of the ceramic body includes grains of ceramic material having a Vickers hardness that is higher than 15 GPa, and a matrix binding the grains, the matrix including a silicon nitride phase and/or a silicon oxynitride phase, the matrix representing between 5 and 40% by weight of the constituent material of the ceramic body. The maximum equivalent diameter of the grains of ceramic material is smaller than or equal to 800 micrometres. The constituent material of the ceramic body has an open porosity that is higher than 5% and lower than 14%. The metallic silicon content in the material, expressed per mm of thickness of the body, is lower than 0.5% by weight.
