  • Patent number: 8497405
    Abstract: The disclosed invention relates to a decontaminant dispenser which may be used as a projectile. The invention also relates to a decontamination process using the decontaminant dispenser. The decontaminant dispenser may be thrown by hand, launched as an artillery shell or the payload for a missile, or dropped by an airplane into the area to be decontaminated. The dispenser may be placed in the area to be decontaminated. The decontaminant dispenser may be ruggedized for use in hostile environments such as those that may be anticipated for military applications.

  • Patent number: 7901618
    Abstract: A large convoluted space, such as a multi-story concourse of an airport is isolated and a chemical or biological agent in the concourse is deactivated. A plurality of deactivation gas sources (100) introduce a deactivation gas at multiple points along the concourse. Fans (66, 106) circulate the deactivation gas, sensors (110) sense concentrations of the deactivation gas at numerous points around the concourse and exhaust fans (66) exhaust air, spent deactivation gas, and some deactivation gas. A control processor (84) controls the generators, the circulation fans, and the exhaust fans in accordance with the gas concentrations sensed by the sensors to increase and decrease deactivation gas concentration in selected subregions of the concourse by increasing or decreasing generation, increasing or decreasing exhausting, or altering flow patterns among subregions.
