Abstract: A mesh system for protecting structural openings, such as windows and doors, from storm damage or intrusion is made of a special cable having an aramid core and a twine twisted steel jacket made of a plurality of steel wires spun onto a bundled aramid fiber core. The mesh includes a substantially straight warp and a woven weft. A mesh system designed for limiting the deflection of the mesh under impact and wind load conditions imposed by a hurricane securely fixes and tensions the mesh along at least the direction of the substantially straight warp. A cable construction, cable diameter, mesh weaving loads and percent open area of the mesh are selected such that the mesh system passes a large missile impact test. Security features including periodic use of a plurality of cables and/or sensors may be added to the mesh.

Abstract: An automatic protective shutter system that is controlled by atmospheric and or human intervention conditions. The shutter consists of a net that can be deployed automatically to cover any opening in a building structure. The shutter net can withstand high winds such as are prevailing winds in a hurricane. The shutter net can also withstand any projectiles that are being encountered in a hurricane. The shutter also protects against the incidence of high ultraviolet UV rays and/or excessive light. The shutter net also detects any tampering by a burglar or vandalism to shut down the opening or to sound an audible alarm. The shutter system is also extremely useful as a shield against the intrusion of insects. The protective shutter system can be controlled locally or by a remote system. The remote system would include a computer system operating through the internet. All of the above can be detected by various sensors such a high wind sensors, ultraviolet sensors and proximity sensors.
