  • Publication number: 20060011054
    Abstract: A multi-layered flexible shield comprising an RF shielding layer and a ballistic control layer. The RF shielding layer is constructed of a conductive fabric, preferably a copper/nickel woven fabric, and a flexible conductive coating formed of an emulsion coating with high attenuating capabilities, and preferably an electrically conductive and electromagnetic radiation absorptive coating composition. The ballistic control layer has upper and lower sub-layers made of a woven ballistic material and a middle sub-layer made of sheets of a non-woven ballistic material, the ballistic materials being Aramid or high molecular weight polyethylene fibers. A detachable cover formed of a woven ballistic material covers the lower surface of the conductive fabric and protects the RF shielding layer from abrasion and environmental conditions.

  • Publication number: 20050092504
    Abstract: A personal electromagnetic security unit for shielding portable electronic communication and data devices such as cell phones and computers. The shielding unit includes a coated liner construction in which a high-attenuation metallized fabric is coated with a second attenuating material to enhance the electromagnetic absorption or reflection characteristics of the unit. This two-part conductive layer forms the inner liner of the shielding unit, with the coated side being protected by the unit's exterior material and preferably an intervening layer of padding.
