A high security two-way virtual cross-barrier observation and communication device has a mounting frame with a hardened core, a pair of digital displays, and a pair of cameras. The mounting frame may correspond to a typical interior door of a building or a relevant component of a vehicle, aircraft, or other relevant application. The hardened core is bullet-resistant and fire-resistant to protect occupants of a protected space from harm. The digital displays and cameras are positioned on opposing sides of the mounting frame, each camera transmitting a live video feed to the opposing display, creating the appearance of a window while protecting occupants. The digital displays may be used to display any desired information. An emergency protocol may be activated to communicate with emergency services. A plurality of laminate layers bond and encapsulate the displays and cameras to the hardened core, forming a rugged, self-contained unit with no moving parts.

The invention relates to a process for the production of a non-fibrous drawn polymer tape, said process comprising the steps: a) compacting a polymer powder in a press to form a compacted polymer bed; b) calendering said compacted polymer bed to form an oriented polymer tape; and c) drawing said oriented polymer tape to form a highly oriented polymer tape; characterized in that step a) comprises compacting the polymer powder at a temperature and pressure such that from 0.1 to 20 wt. % of the polymer powder as measured by DSC is melted. The invention also relates to a tape obtainable by the above process, and a monolayer, multilayered material sheet and ballistic resistant article comprising such a tape.

An enclosure system may be formed of a lightweight panel with a thin non-porous membrane that enables the extraction and leak detection of hazardous gases from housing equipment such as vacuum pumps, valves, abatement equipment and the like. Additionally, the enclosure system includes a one or multiple layers of wire mesh which prevent projectiles with a high kinetic energy from escaping from the housing equipment thereby minimising the risk of an explosion causing parts or panels to be ejected from the enclosure system.

The invention is the first modification of the Patent Application with number 1009231 and involves an additional system of three levels which reinforces and improves the dynamic armor of main battle tanks using compressed ferromagnetic powder and electromagnetically reinforced. The main characteristics of the first invention (DE-1009231) for the armor system of tanks and battle vehicles was the use of compressed powder from magnetized or non-magnetized ferromagnetic pulverized materials (Fe, Ni, Co) or other similar synthetic materials that enrich or enhance the desired mechanical properties and the effect of electromagnetic amplification between two solid passive armor plates. The first level (FIG. 1, 2) concerns the placement of high temperature silicone or other material of the same mechanical properties at a suitable thickness proportional to the threat, between the outer passive solid shielding plate and the compressed ferromagnetic powder. The second level (FIG. 1, 3) concerns the modification of the layer containing the ferromagnetic powder by the distribution of the ferromagnetic powder contained in pellets or cubes or rectangular parallelepipeds or other basic geometric volumes from polymeric material with viscous elasticity or other kinds of material with same mechanical properties of thin walls or alternatively its placement in a spatial network with cubic or conical or spherical partition volumes with thin walls made of polymeric material with viscoelasticity or other material with the same mechanical properties and then compress them between the plates of solid passive armor. The third level of reinforcement (FIGS. 1, 4) was achieved by placing a layer of explosive material on the visible side facing to the ferromagnetic powder of the inner passive solid shielding plate in combination with percussion, perforation and temperature sensors. The layer of the explosive may be in a single layer or be contained as based on the inside surface of each individual area of the spatial network or similarly to separate cubes or rectangular parallelepipeds.
