Protective shields configured to prevent projection against projectiles, such as during excavating and/or mining operations, are provided. The protective shields include a base layer comprising one or more transparent polycarbonate layers, a sacrificial polycarbonate layer comprising a transparent polycarbonate, and an air gap positioned directly between at least a portion of the base layer and the sacrificial polycarbonate layer. The sacrificial polycarbonate layer is directly or indirectly attached to the base layer in a manner to provide the air gap positioned between the base layer and the sacrificial polycarbonate layer.

An anti-ballistic protection system for protecting an interior space in a building. The ballistic barrier includes a laminated material having a plurality of layers of lightweight, flexible, ballistic resistant material such as woven sheets which are secured together into the laminate using a adhesive, heat weld, or stitching. The ballistic barrier is configured to be in a compact retracted state which can be deployed to provide a protective state to protect against kinetic ballistic projectiles. The system may include an automated control system operably configured to change the state of the ballistic barrier from the retracted state to the protective deployed state, such that upon sensing a threatening event or condition triggers a transition from the retracted state to the deployed protective state such that in the protective state. The ballistic barrier in the deployed state is configured to be resistant to penetration by high-speed ballistic projectiles such as a bullet fired from a gun or a shrapnel from a bomb to protect the interior space.

An anti-ballistic protection system for protecting a space in a building or vehicle comprising a protective barrier including one or more sheets of a laminated material having a plurality of layers of lightweight, flexible, ballistic resistant material such as woven sheets which are secured together using a glue, heat weld, or stitching. The system may include an automated control system operably configured to cause a change in state of the barrier from a retracted state to a protective deployed state, which may include a sensing system operably configured to detect a threatening event, wherein the sensing system upon sensing the threatening event triggers the barrier to transition from the retracted state to the deployed protective state such that in the protective state, the barriers are adapted to be resistant to penetration by high-speed ballistic objects such as bullets.

A defense structure and methods of use for penetrating the defense structure with a projectile from a first side and preventing a projectile from penetrating the defense structure from a second side. The defense structure comprising a plurality of wedges arranged to rotate and abut each other using a tensioning member, such as a spring. Ballistic and resilient members are provided on a rear surface of the plurality of wedges to prevent a projectile from penetrating the defense structure through deflection and/or adsorption of the projectile. A gap is formed between at least two of the plurality of wedges when a projectile is urged between the plurality of wedges from the first side. The tensioning member urges the plurality of wedges to rotate and abut each other after the projectile passes through the gap. The defense structure may be partially concealed within a structural element.

Improvements in a shield is disclosed. The steady shield integrates a vest with a shield that can be made from a protective ballistic material that protects the user from projectiles, bottles, heat or debris. An adjustable arm connects the vest to the shield and allows the shield to be moved at least one of towards, away and to the sides and higher and lower relative to the user. Once the shield is positioned the shield will remain in the set position to allow both arms and hands of the user free for other activities. The shield also provides a platform for the storage of tools or other features such as, but not limited to, ammunition, tear gas, water, first aid, lighting, radio, camera, GPS or other display.
