  • System for filtering radio frequency and infrared optical transmissions
    Patent number: 8896916
    Abstract: A system of anti-surveillance security windows having one or more conductive glass substrates and one or more layers incorporating an organic radical cation compound, wherein the layers reflect in the infrared region, is demonstrated. Preferably, the organic radical cation compound is a salt of an aminium radical cation. The security windows may contain one or more layers of a multilayer interference stack of a metal/metal or metal/metal oxide design.
    Type: Grant
    Filed: March 21, 2011
    Date of Patent: November 25, 2014
    Assignees: Madico, Inc., Optodot Corporation
    Inventors: Peter K. Barrett, David W. Avison, Steven Carlson
  • Window films with reflective organic and metal layers
    Patent number: 8730571
    Abstract: A system and method for windows films having one or more layers incorporating an organic free radical compound, wherein the layers reflect in the infrared region, and one or more layers of a multilayer interference stack of a metal/metal or metal/metal oxide design. Preferably, the organic free radical compound is a salt of an aminium radical cation. One or more layers of the multilayer interference stack may incorporate an aminium radical cation compound. Also provided are security windows that utilize such window films.
