Mobile sound and light resistant electromagnetic isolation chamber
View Patent ↗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.
1. An electromagnetic isolation chamber to isolate at least one electronic communication device of the type having an audio input that receive sounds, the at least one electronic communication device having electromagnetic transmission capabilities that wirelessly transmit signals, the chamber comprising:
an ungrounded housing having a form factor dimensioned to fit into 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 the at least one electronic communication device to be placed within and enclosed by said cavity, the openable portion including a second position that seals said cavity such that wireless transmissions from the at least one electronic communication device are substantially prevented from passing between said cavity and the outside world,
wherein the housing further includes a sound-reducing shield configured to acoustically decouple the cavity from sound outside of the cavity so that the housing, in use, prevents the audio input of said at least one electronic communication device from picking up sound originating from outside of the cavity when said at least one electronic communication device is disposed within the cavity with the openable portion set in the second position.
2. The electromagnetic isolation chamber of claim 1 wherein said form factor comprises a form factor of an aerosol can.
3. The electromagnetic isolation chamber of claim 2 wherein said form factor comprises a device used to repair a vehicle.
4. The electromagnetic isolation chamber of claim 1 wherein said form factor comprises a handheld structure typically used for a purpose having nothing to do with electromagnetic isolation.
5. The electromagnetic isolation chamber of claim 1 wherein said housing includes a threadably removable cap.
6. The electromagnetic isolation chamber of claim 1 wherein said housing is dimensioned such that said cavity is large enough to accommodate at least one cellular telephone or similar device.
7. The chamber of claim 1 further including a radio frequency absorbing foam disposed within said chamber.
8. The chamber of claim 1 further including foam disposed within the chamber.
9. The chamber of claim 1 wherein the sound shield is structured to at least in part surround said chamber.
10. The chamber of claim 1 wherein said chamber is portable.
