  • Patent number: 8919549
    Abstract: The invention relates to carrying cases for wireless devices including cell phones, wireless tablets and laptop PC's which provide EMF shielding for the user. The wireless devices are inserted into a case comprising EMF shielding material and a cover including shielding material is flipped thereover to provide further radiation protection. The case involves several embodiments such as a flat flip case, a fixed bent edging flip case and a flexible folding edge flip case. A flip type case shielded cover added to existing wireless device open faced skin covers. Another embodiment of the invention involves a wireless device pocket shield wherein a shielded insulation envelope having a wireless device placed therein is dropped into an apparel pocket.

  • Patent number: 8205744
    Abstract: A unique laptop computer or similar device carrying case, which can also shield an individual from electromagnetic radiation (EMF) including RF microwave radiation and also heat transfer from the laptop computers when opened or in the closed positions. A conductive fabric is positioned against non-conductive plastic sheeting and is rolled up on itself, on four sides, to provide a larger effective virtual shield in the two side insulating sections, each of which includes an inner luan material with optional magnetic shielding or a perforated metal shield and a solid metal shield in the base to protect against electromagnetic radiation. The shield can be incorporated in existing cell phone/PC cases or flip top cell phone cases. Further, a pocket shield can be used to store cell phones in apparel pockets.

  • Patent number: 7772504
    Abstract: A unique laptop computer or similar device carrying case which can also shield an individual electromagnetic radiation including RF microwave radiation and also heat transfer from the laptop computers when opened or in the closed positions. The invention includes sewn insulating sections along the internal nylon face and an external leather face. A conductive fabric is positioned against the non-conductive plastic sheeting and is rolled up on itself, on four sides, to provide a larger effective virtual shield in the two side insulating sections, each of which includes an inner perforated metal shield and a solid metal shield in the base to protect against electromagnetic radiation. The sections fold inwardly to provide a carrying case held together with four Velcro® strips on the exterior of the case.

  • Patent number: 6515223
    Abstract: A shielding device to protect cellular or cordless telephone users from EMF including the RF microwave radiation comprises a flat internal flexible conductive sheath which is positioned on the top of a flat non-conductive sheathing with a border of non-conductive sheathing extending outwardly thereabout. The sheath assembly is rolled inwardly on both sides and then folded in back on the top and bottom. The recessed are between the rolls of conductive cloth and nylon sheathing is applied thereto. The non-conductive sheathing is cut on both ends of the back region for better audio and the rolls of non-conductive sheathing are trimmed on both sides at an intermediate position. A perforated vinyl/leather front is positioned thereover, hook and loop or Velcro® mounting tabs sewn thereon and a surrounding cover positioned thereover. The cellular or cordless telephone is positioned thereon and the shielding device is wrapped thereabout and locked with an elastic strap, for storage only.

  • Patent number: 5367309
    Abstract: A shielding device used on hand-held cellular phones comprises a substantially rectangular shield which extends adjacent to the antenna. A downwardly extending slide arm portion of the shield terminates in a substantially pointed end surface formed by the outer edge of the shield sloping inwardly to engage the inner edge of the slide arm, said outer edge having a notch on the exterior surface thereof. The device also includes a paddle arm portion extending perpendicular to the shield area and then downwardly to terminate in an enlarged paddle engaging the rear of the phone. The shield is mounted to a hand-held cellular phone with the shield area extending vertically upward adjacent to the antenna and the paddle arm extending over the top of the phone and terminating in the rear paddle and the paddle arm extending over the top of the phone. The shield is held in place by an O-ring which surrounds the phone and fits in the notch in the slide arm.
