Embodiment Construction

[0025] In describing preferred embodiments of the present invention illustrated in the drawings, specific terminology is employed for the sake of clarity. However, the invention is not intended to be limited to the specific terminology so selected, and it is to be understood that each specific element includes all technical equivalents that operate in a similar manner to accomplish a similar purpose.

[0026] The present invention relates to an electromagnetically-shielded bomb suppression device 10 that serves as a portable ballistic shield that is lightweight, flexible, and can be easily placed over an explosive device. The invention also provides a ballistic shield that will give radio frequency (RF) shielding for the prevention of remote detonation of an explosive device. In the instance that the explosive device is not detonated by a RF signal, the ballistic shield will have some fragment control capabilities.

[0027] Referring to FIG. 1, the bomb suppression device 10 is a multi-...

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. The outer edge of the bomb suppression device has a weighted, flexible rim that aids in securing the unit to the surrounding surface, thereby electronically isolating the explosive device.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an electromagnetically shielded, portable device for protection against remote detonation of an explosive device, and also having ballistic shielding capabilities. [0003] 2. Related Art [0004] As used herein, “ballistic materials” means materials that provide blast-fragment mitigation. The construction of ballistic materials is well known in technology. Typical ballistic materials would consist of multiple layers of a woven or non-woven Aramid, such as Kevlar® or Twaron®, or high molecular weight polyethylene, such as Dyneema® or Spectra®, fibers or fabrics or a combination thereof. As used herein, “Aramid” means a manufactured fiber in which the fiberforming substance is a long-chain synthetic polyamide in which at least 85% of the amide (—CO—NH—) linkages are attached directly between two aromatic rings. [0005] Most ballistic materials have been incorporated in clothing such as fla...
