  • Publication number: 20110097147
    Abstract: A non-lethal vehicle device provides for the selective, remotely-deployed controlled stop of a targeted vehicle regardless of wheel or undercarriage configuration. The device is comprised of a combination of a remote arm/safe mechanism, a remote deployment controller, spike/snare deployment mechanism(s), a “speed bump” type housing that can protrude (be driven over until deployed) or be submerged, and one or more snares with a plurality of spikes. A combination of sensors may provide independent deployment once armed.

  • Patent number: 7762189
    Abstract: A pyrotechnically powered actuator having a bellows that provides a force and stroke upon initiation is disclosed. The actuator includes a housing body with a first end and a second end. The bellows is coupled to the first end of the housing body. A cover is coupled to the second end of the housing body. An initiator is located within the housing body and includes a pyrotechnic material and a bridge element. The housing body, the bellows, and the cover define a hermetically sealed chamber. The bellows is compact, lightweight, and can withstand internal and external pressure at least as high as 3,000 psi. An exemplary embodiment includes a housing body that provides a compartment for adding supplemental pyrotechnic material. Further exemplary embodiments of the actuator include a chip initiator that requires less than 1 amp to function in less than 10 milliseconds.

  • Publication number: 20090314174
    Abstract: An ARM-FIRE device for a pyrotechnic system includes a first pyrotechnic, a second pyrotechnic, a passage extending between the first and second pyrotechnics, and an actuator/blocking device positioned between the first and second pyrotechnics. The first pyrotechnic is configured to be ignited by a heat source, and the second pyrotechnic is configured to be ignited by the first pyrotechnic in the FIRE arrangement. The actuator/blocking device includes a body configured to move between a first position in the SAFE arrangement and a second position in the FIRE arrangement, an aperture extending through the body, and an actuator. The aperture is offset from the passage in the first position of the body and is aligned with the passage in the second position of the body. The actuator is configured to move the body between the first and second positions. The first pyrotechnic, the second pyrotechnic, and the actuator/blocking device occupy a volume of approximately 3.0 cubic inches or less.
