Method for temporarily inactivating a wireless communication device
View Patent ↗A wireless communication device such as a cell phone is rendered temporarily inoperable by enclosing the device in a container such as a heat sealable bag ( 1 ) which has been metallized so that when the device ( 2 ) is sealed in the container ( 1 ) it is surrounded by a metal layer ( 9 ) which blocks signals to and from the device ( 3 ) to thereby render it inoperable. The device is sealed within the container ( 1 ) by a seal such as a heat seal which will reveal any attempt to remove the device from the container.
1. A method for temporarily inactivating a wireless communication device which sends and receives an electromagnetic communication signal, said method comprising enclosing said device in a container and locking said container with a seal which prevents removal of said device from said container, said container comprising a signal shielding layer wherein said signal shielding layer comprises an electrically conductive layer or a microwave absorptive layer, said signal shielding layer being configured to surround said device when said device is enclosed within said container to thereby attenuate said communication signal and render said device inoperable; said seal being adapted so that breakage of said seal to unlock said container can be visually detected; wherein said container is a heat sealable plastic bag; said signal shielding layer is coated or laminated onto said bag; and said bag is locked by heat sealing a heat sealable portion of said bag whereby said heat sealing seals said device in said bag.
2. The method of claim 1 which further includes keeping said device spaced apart from said signal shielding layer while said device is enclosed within said bag.
3. The method of claim 2 wherein said device is kept spaced apart from said signal shielding layer by inserting a spacer layer between said bag and the device within the bag.
4. The method of claim 3 wherein said signal shielding layer is metal.
5. The method of claim 4 wherein said metal is aluminum.
6. The method of claim 3 wherein said device is a cell phone.
7. The method of claim 1 wherein said device is a cell phone.
8. The method of claim 1 wherein said electromagnetic communication signal is an infrared beam.
9. A method for temporarily inactivating a wireless communication device which sends and receives an electromagnetic communication signal, said method comprising enclosing said device in a container; said container comprising a signal shielding layer wherein said signal shielding layer comprises an electrically conductive layer or a microwave absorptive layer, said signal shielding layer being configured to surround said device when said device is enclosed within said container to thereby attenuate said communication signal and render said device inoperable, wherein said container is a bag and said device is enclosed within said bag by placing said device in an open end of said bag and then folding over said open end of said bag to thereby close said bag with said device therein.
