Assignee:

Sandia Corporation - Albuquerque NM

International Classification:

US Classification:

73866, 7386321, 7386323, 7386481, 436 28

Abstract:

An apparatus and method for detecting explosive-indicating compounds in subsurface soil. The apparatus has a probe with an adsorbent material on some portion of its surface that can be placed into soil beneath the ground surface, where the adsorbent material can adsorb at least one explosive-indicating compound. The apparatus additional has the capability to desorb the explosive-indicating compound through heating or solvent extraction. A diagnostic instrument attached to the probe detects the desorbed explosive-indicating compound. In the method for detecting explosive-indicating compounds in soil, the sampling probe with an adsorbent material on at least some portion of a surface of the sampling probe is inserted into the soil to contact the adsorbent material with the soil. The explosive-indicating compounds are then desorbed and transferred as either a liquid or gas sample to a diagnostic tool for analysis. The resulting gas or liquid sample is analyzed using at least one diagnostic tool selected from the group consisting of an ion-mobility spectrometer, a gas chromatograph, a high performance liquid chromatograph, a capillary electrophoresis chromatograph, a mass spectrometer, a Fourier-transform infrared spectrometer and a Raman spectrometer to detect the presence of explosive-indicating compounds.

Appl. No.:

11/688707

Inventors:

Ronald Woodfin - Sandia Park NM, US

Assignee:

Los Alamos Technical Associates - Albuquerque NM

International Classification:

F41H 11/00

US Classification:

089036090, 089036170

Abstract:

A multi-layer lightweight protective armor system for application to an unarmored vehicle includes an energy absorbing layer adapted to be mounted adjacent an exterior vehicle surface, an explosive layer formed from an explosive material and disposed on the energy absorbing layer, and a trigger layer disposed on the explosive layer. The trigger layer is operable to initiate an explosion in the explosive layer when a projectile impacts the trigger layer and the energy absorbing layer is operable to contain the explosion and prevent the explosion from reaching the exterior vehicle surface.

Abstract:

A floating modular bridge has a plurality of modules of two types. Most modules are flexible fabric envelopes having a parallelogram profile that attains shape and strength when filled on site with a rigid foam that is injected into the envelope. The other module is a keystone that has a trapazoidal profile. These modules are strung together by cables to make a lightweight bridge.
