Examples herein describe systems and methods for securing an opening and disorienting an active shooter. A command device can send a deployment command to a zone in a building. In response, canopies in the zone can deploy a roll-up door made of Kevlar that electromagnetically locks shut. The canopies can include blindingly bright lights and deafening sirens that disorient the shooter. The doors can block off rooms or other areas of a school where children can huddle safely until the shooter is apprehended. Canopies without doors can also be used at some openings to disorient the shooter.

The present invention refers to a mechanically activated cementitious composite for stopping the impact of firearms, which involved the designing of mixes of Portland Composite Cement PCC mechanically activated through high energy mechanical milling (HEM) with other ingredients, such as: Ordinary PCC Cement, fine sand, fibers, and polymeric additives, among other compounds, to prepare high-performance composite walls capable of stopping several calibers up to type 50 (typically loaded in Barret rifles). In accordance with Mexican and U.S. Standards for ballistic tests, which entail the approval of the concrete ballistic-resistant wall as long as it resists one impact with a 50 caliber Barret, the present invention allows the construction of composite walls (with dimensions of 40×40×15 cm) with mechanically activated cement and performance complying with the standards.

An example barrier can be switchable between an at least partially collapsed state and at least partially expanded state (e.g., a deployed state). For example, the barrier can be formed from a continuous sheet and a plurality of rigid sections (e.g., rigid panels) attached or incorporated into the continuous sheet. The barrier can also include a plurality of hinges, such as hinge lines, between the panels that are formed from the continuous sheet. The hinges enable the barrier to be rigid foldable (e.g., the hinges can fold and unfold while the rigid sections remain stiff and rigid) between the expanded and collapsed states.

A smart desk and barricade provide ad-hoc protection during emergencies and an augmented presentation environment. A first desk tabletop includes a connection positioned on an underside of the first desk tabletop, that is configured for detachable coupling to a desk frame. Removal of the tabletop from the desk frame provides a shield. An interlocking element is positioned on one or more edges of the first desk tabletop. The interlocking element is configured to temporarily connect to an edge of a second desk tabletop. A temporary attachment of the first desk tabletop to the second desk tabletop forms a barricade system. In some embodiments, a computing device is integrated into the desk tabletop. A smart room environment may network the desk with integrated computing device to other computing devices in the room.

Exemplary embodiments of the present disclosure provide a system, apparatus, and methods for producing a high-performance camouflage and thermal management composite fabric textile systems. The systems comprise woven and non-woven composite fabrics consisting of layers for thermal and electromagnetic wave propagation as well as human thermal emission control. The systems incorporate thermal plastic insulation, felt insulation, electromagnetic wave absorption materials, electromagnetic wave propagation and thermal emission control elements, and camouflage pigment patterns. Dots containing encapsulated metallic particulates enable omni-spectral electromagnetic wave and thermal radiation signature manipulation and control as well as cost-effective manufacturing. Single blended textile processed via needle punching produces hair/fur-like protrusions made from a multilayer fabric composition having EM wave and thermal radiation control elements. The protrusions subsequently contain EM propagation and thermal emission control elements on their surfaces for omni-spectral camouflage and detection mitigation. The systems expand the options for meeting the demands of today and future stealth missions.

A shade adapted for covering a classroom viewing window and assisting with compliance with emergency protocol during an emergency is disclosed. The shade may include a plurality folds connected to each other by a plurality of hinges configured to cover a classroom viewing window. Emergency related information and status indicators may be revealed upon the unfolding of the shade to assist teachers, school officials, police, and others to comply with established school emergency protocol. The shade further fulfills the requirement that the classroom viewing window be covered during an emergency lockdown. The shade may function as a standard “Exit” sign during non-emergency time. Another shade may include a case holding a material portion with handles that enable the shade to be moved up and down.

A ballistic-resistant barrier assembly including an elongated barrier having a vertical portion including a substantially horizontal elongated top edge, and a ballistic-resistant device having a first ballistic-resistant panel including an elongated top edge, and an engagement portion affixed to the elongated top edge of the first ballistic-resistant panel, wherein the engagement portion of the ballistic-resistant device is disposed adjacent the elongated top edge of the barrier so that the first ballistic-resistant panel is disposed in a vertical orientation adjacent the vertical portion of the barrier.
