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.

Silicon carbide composite materials contain CSiC with a density of 2.95 to 3.05 g/cm.sup.3 and a fiber bundle content of 2 to 10 wt. %. The fiber bundles have a length of 6 to 20 mm, a width of 0.2 to 3 mm, and a thickness of 0.1 to 0.8 mm. The fiber bundles are filled with a cured phenolic resin content of up to 45 wt. %, and the protected fiber bundles are integrated into an SiC matrix. A method produces the silicon carbide composite materials.

Disclosed herein are embodiments of a method for averting a danger. The method is performed by a control apparatus for an unmanned vehicle, and the method involves obtaining a plurality of pieces of sensor information. At least partially depending on the obtained pieces of sensor information it is determined whether a danger exists. If it is determined that a danger exists, then at least one averting measure for averting the danger is determined, and the at least one averting measure is performed or caused to be performed.

A device for rapid removal/reinstallation of a back of a seat of a vehicle, the back being attached, by at least one first strap, to a ceiling. The device includes a hanging intermediary structure and a fixed structure integral with the ceiling and retaining the structure in the use position of the seat, in which it has been brought with an upward movement, and locking the structure in the use position or unlocking it such that it is moved away from the ceiling to release the tension exerted by the first strap and allow the structure to be disengaged from the retaining unit. The back can thus be removed or reinstalled without any action on the tension setting of the strap.

A robotic mobile low-profile transport vehicle is disclosed. The vehicle can comprise a first transport module having a frame assembly, a mobility system, and a propulsion system and a second transport module having a frame assembly and a mobility system. A multi-degree of freedom coupling assemblage can join the first and second transport modules together. The vehicle can include a first platform supported about the frame assembly of the first transport module, and a second platform supported about the frame assembly of the second transport module. Each of the platforms can be configured to receive a load for transport. Additionally, the vehicle can include a control system that can operate to facilitate intra-module communication and coordination to provide a coordinated operating mode of the first and second transport modules and the coupling assemblage about a given terrain.

A frame includes a pair of self-propelled lateral modules, which extend in a longitudinal direction and can be mutually removably coupled in a transverse direction. The modules are adapted to contribute to create, when assembled, a support structure for a central module, which can be removably coupled to the frame and is provided with a control system, which is configured to control movements and actuation of the self-propelled lateral modules. Each one of the self-propelled lateral modules includes a pair of bearing portions, and a connection portion, which mutually constrain the bearing portions and permit relative movement thereof between an extended configuration, in which the bearing portions define a greater longitudinal extension of the self-propelled lateral module, and a compact configuration, in which the bearing portions define a smaller longitudinal extension of the self-propelled lateral module.

The invention is a method for applying ballistic protection to a vehicle door to protect against ballistic impact comprising: obtaining a plurality of ballistic-resistant panels, inserting each of said plurality of ballistic-resistant panels into an interior cavity of the vehicle door; and attaching each said plurality of ballistic-resistant panels to an interior surface of an exterior door panel of the vehicle door so as to form said contiguous ballistic-resistant panel assembly inside said interior cavity.
