  • Fast neutron resonance radiography for elemental mapping
    Patent number: 6693281
    Abstract: Methods and apparatus involving neutron resonance radiography are used to map the elemental composition of an object. Sets of neutrons having energies within particular energy bands are directed through an object to be imaged. The attenuation of the neutrons passed through the object is detected, and that data can be used to detect explosives, weapons, drugs and other contraband.

  • Apparatus for supporting and tensioning a stencil
    Patent number: 6289804
    Abstract: A support and tensioning frame for a stencil to enable solder paste to be applied to printed circuit boards and other electronic substrates includes a support frame engaged with at least two opposed mounting members. Each mounting member includes at least one projection for engaging an aperture in a stencil to mount the stencil under tension. A permanent-biasing mechanism engages one or more of the mounting members to place the stencil under tension. A second biasing mechanism engages the mounting member to provide a bias opposite that of the permanent-biasing mechanism to facilitate release of a mounted stencil.
