  • Protecting military targets against weapons having IR detectors
    Patent number: 4756778
    Abstract: Pyrolyzed carbon fibers are intercalated with alkali metal by contacting fibers with hot metal vapors at a specified temperature to produce an infrared emissive chaff. This chaff can be released into the air to produce a heat generating cloud, which can serve as an infrared decoy or screen to protect military targets against weapons having infrared detectors. The chaff gives off a longer lasting, more moderate heat supply due to the intercalation of its active element, and is much easier to store and handle than prior art pyrophorics.
    Type: Grant

  • Mixed semiconductor film device for monitoring gases
    Patent number: 4636767
    Abstract: A method of monitoring gases using electronic conductivity changes in ordd organic semiconductor films comprising an insulated substrate fabricated to an interdigital microelectrode and coated with a vapor sensitive semiconductor film. Variations in current flow caused by vapors interacting with the film are indicative of the vapor type.
