Abstract

A device enclosing a volume shielded from certain levels of sound, light and electromagnetic radiation, such device that prevents electromagnetic communications and recording devices from transmitting and receiving communications from outside of the devices protected environment while remaining mobile and ungrounded.

Claims

1. An electromagnetic isolation chamber containing a volume of space electro-magnetically isolated from the surrounding environment, comprising:

a) a wall enclosing said volume, said wall having first electromagnetic shielding surrounding said volume,

b) a sound reducing shielding disposed within said chamber or exposed in an exterior treatment such as sound reducing/proofing material, rubber armoring or encasement in Poly urethane foam, and the like, and

c) a lining consisting of Radio Frequency Absorbing Foam disposed within said chamber covering the sides of said volume in a manner and proportion to best optimize the abilities of radio frequency absorbing being utilized, including but not limited to directing the effective portion of the Radio Frequency Absorbing Foam towards the inside of the chamber.

2. A chamber in accordance with claim 1 wherein said wall comprises a plurality of sides defining a box.

3. A chamber in accordance with claim 2 wherein said box is openable and has a top portion and a base portion.

4. A chamber in accordance with claim 3 wherein said top portion is conductively attached to said base portion when closed.

5. A chamber in accordance with claim 4 wherein said top portion is attached by an attachment which comprises a lid hinged from the body and securable by a latch or accessible or by other methods such as sliding lids, magnetic lids, swing out lids and the such.

6. A chamber in accordance with claim 5 further comprising a shielding gasket between said top portions.

7. An electromagnetic isolation chamber comprising:

a housing having a form factor commonly found in a vehicle, said housing comprising a material that substantially prevents electromagnetic radiation from passing therethrough, said housing including an openable portion and defining a cavity therewithin, said openable portion having a first position that allows an electronic device to be placed within said cavity and a second position that seals said cavity such that electromagnetic radiation is substantially prevented from passing between said cavity and the outside world.

8. The electromagnetic isolation chamber of claim 7 wherein said form factor comprises an aerosol can.

9. The electromagnetic isolation chamber of claim 8 wherein said form factor comprises a device used to repair a vehicle.

10. The electromagnetic isolation chamber of claim 7 wherein said form factor comprises a handheld structure used for a purpose having nothing to do with electromagnetic isolation.

11. The electromagnetic isolation chamber of claim 7 wherein said housing includes a threadably removable cap.

12. The electromagnetic isolation chamber of claim 7 wherein said housing is dimensioned such that said cavity is large enough to accommodate at least one cellular telephone or similar device.
