Abstract: A non-pyrotechnic disseminator includes a body portion with a cover; a first compartment that holds disseminating materials; a spring-loaded piston; a cable connecting the piston to a base of the body portion: a second compartment adjacent to the first compartment; a control mechanism; and an initiator mechanism. The control mechanism sets a delay timing countdown for initiation of dissemination of the disseminating materials out of the body portion. The initiator mechanism begins the delay timing countdown. The second compartment includes a delay fuze module; and a cutting mechanism in contact with the cable. The delay fuze module processes the delay timing countdown, and upon expiration of the countdown, sends a signal to the cutting mechanism to cut the cable. When the cable cuts, the spring uncoils and pushes the piston, which forces the disseminating materials out of the body portion by rupturing the cover.

Abstract: The present invention is directed to an air intake for an aerosol sampling device, the air intake being inflatable and deflatable.

Abstract: A non-pyrotechnic disseminator includes a body portion with a cover; a first compartment adjacent to the cover that is configured to hold disseminating materials; a chamber adjacent to the first compartment; a disk within the chamber and adjacent to the first compartment; a flow control device adjacent to the chamber opposite the disk; a second compartment adjacent to the flow control device and including a pin; an actuating mechanism connected to the pin; a third compartment adjacent to the second compartment opposite the flow control device that is configured to hold compressed gas; and a seal separating the second compartment from the third compartment. Actuation of the actuating mechanism causes the pin to break the seal causing release of the compressed gas into the second compartment and through the flow control device in a predetermined delayed timing, and then causing the compressed gas to burst the disk thereby pushing the disseminating materials out of the body portion by rupturing the cover.

Abstract: A flow modulator to control the flow of an aerosol to an aerosol detection and/or monitoring system and other aerosol flow systems includes a chamber having an inlet and an outlet, a diverging section of the chamber beneath the inlet that has a flow divider at the center to divide the aerosol into fractions, a recirculation section in which the divided aerosol fractions are recombined, and a converging section that channels the recombined aerosol fractions to the outlet of the chamber.

Abstract: The present invention relates to a method and apparatus for redirecting a flow of aerosol-containing air into, for example, an aerosol sampler. The apparatus comprising a device for redirecting a portion of the flow of aerosol-containing air into an air intake disposed within the flow of aerosol-containing air, preferably using eduction caused by a pressurized gas stream. A sampling tube having an opening for receiving aerosol-containing air is disposed within the air intake to collect the redirected portion of aerosol containing air.
