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.

A tugger train trailer is disclosed, including a frame and drive-on surfaces for holding a trolley cart. Transport vehicle drive-on surfaces for an autonomous transport vehicle moving the trolley cart are also provided such that a unit of trolley cart and autonomous transport vehicle can drive on the drive-on surfaces.

A de-escalation device has vehicle mount and an elongate arm connected to the vehicle mount. An expandable hook toward the end of the elongate arm is adjustable between a contracted position and an expanded position. The de-escalation device is configured to form a first opening in a wall structure by puncturing the end of the elongate arm through the wall structure while the hook is contracted and subsequently form a second, larger opening by withdrawing the elongate arm while the hook is expanded. The elongate arm can have proximal and distal arm sections that are rotatably adjustable with respect to the vehicle mount and one another. One or more remotely controllable de-escalation tools can be deployed from the end portion of the elongate arm.

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.

Vehicle armor may include an assembly of components including an outer armor pack, an air gap, an inner armor pack, and a high energy absorbing layer. At least one version of the outer armor pack may include an outermost outer fiber reinforced composite protective layer of ≧1 mm thickness, an outer ceramic armor layer, and an inner fiber reinforced composite support layer to absorb residual energy from small arms. The air gap may be between 1-10 mm to allow for deflection of the outer armor pack. The inner armor pack may include an outer fiber reinforced composite protective layer of ≧0.5 mm thickness, an inner segmented ceramic armor layer, and an innermost inner fiber reinforced composite layer of ≧10 mm thickness. The high energy absorbing layer may have ≧25 mm thickness and be configured to mitigate the effect of residual fragments defeating the outer and inner armor packs.

This invention provides impact detection and vehicle cooperation to achieve particular goals and determine particular threat levels. For example, an impact/penetration sensing device may be provided on a soldier's clothing such that when this clothing is impacted/penetrated (e.g., penetrated to a particular extent) a medical unit (e.g., a doctor or medical chopper) may be autonomously, and immediately, provided with the soldiers location (e.g., via a GPS device on the soldier) and status (e.g., right lung may be punctured by small-arms fire).
