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 () which has been metallized so that when the device () is sealed in the container () it is surrounded by a metal layer () which blocks signals to and from the device () to thereby render it inoperable. The device is sealed within the container () by a seal such as a heat seal which will reveal any attempt to remove the device from the container.

Method for temporarily inactivating a wireless communication device

A combination of filters for filtering selected wavelengths of electromagnetic radiation is provided on a transparent substrate such as a plastic film or glazing of a window. The combination of filters prevents or attenuates the passage of wavelengths through the substrate into a building, where the passage of the wavelengths into the building could adversely affect people or machinery within the building. The combination of filters is useful improve wireless networks performance by blocking or attenuating undesired electromagnetic interference, and radio frequency interference.

System and method for filtering electromagnetic transmissions

A combination of filters for filtering selected wavelengths of electromagnetic radiation is provided on a transparent substrate such as a plastic film or glazing of a window. The combination of filters prevents or attenuates the passage of wavelengths through the substrate which would pose a security risk. The combination of filters is useful to prevent unauthorized data collection and information exchange from or within buildings or otherwise prevent such unauthorized data collection and information exchange from, for example, computer monitors or screens, personal digital assistance, and local area networks. The substrate with the combination of filters may be in the form of a bag or a tent.

System and methods for filtering electromagnetic visual, and minimizing acoustic transmissions

The invention describes a system and methods for filtering electromagnetic and visual transmissions and for minimizing acoustic transmissions. Various combinations of UV, IR, and yellow-tinted filters are applied in various physical configurations to a transparent substrate such as a plastic film or glazing of a window for modifying selected wavelengths of electromagnetic radiation. For instance a light filter may have a multi-layered metallic sputtered stack having a relatively low sheet resistance. The combination of filters prevents or attenuates the passage of selected wavelengths through the substrate as needed to address security risks. The combination of filters is useful to prevent unauthorized data collection and information exchange from or within buildings or otherwise prevent such unauthorized data collection and information exchange from, for example, computer monitors or screens, personal digital assistants, and local area networks.
