  • Publication number: 20100107859
    Abstract: A method and apparatus triggers motion triggered improvised explosive devices (IEDs) from a distance outside the device's zone of destruction. IEDs having infrared motion detection trigger mechanisms are detonated by passing remotely generated laser beams over the area within which the IED is located. The moving reflected background scattering of light from the passing laser beams as well as possible direct passing laser illumination of the IED infrared motion detector activate the IED trigger mechanism, causing the IED to detonate. Operation of the invention is remote from the destruction zone of the IED, thereby preserving personnel and materiel.

  • Patent number: 5890802
    Abstract: A device and method for mixing an aspirated fluid slug (40), such as a DNA sample and reagent, within a capillary tube (28) through the electrical deflection of a diaphragm, such as a piezo-ceramic disk (12). The device (10) includes first and second mounting plates (16, 18). The piezo-ceramic disk (12) is sandwiched between two O-rings seals (14) and the two mounting plates (16, 18) to form an air seal (21) between the disk (12) and the first mounting plate (16). A first opening (24) receives an end (26) of the capillary tube (28) and extends almost completely through the first mounting plate (16) such that the end (26) is essentially perpendicular and adjacent to the disk (12). A smaller axially-aligned second opening (30) connects the air seal (21) between the disk (12) and the first mounting plate (16) to dead air volume (42) in the capillary tube (28). A third O-ring seal (34) seals the capillary tube (28) to the first mounting plate (16) at the first opening (24).
