Pressure-Sensitive Sampling Wands for Homeland Security Applications

Sensor Placement for Urban Homeland Security Applications

We simulated a sensor network that detects and tracks the release of harmful airborne contaminants in an urban environment. The simulation determines sensor placement in that environment. The effort required integration of models from computational fluid dynamics (CFDs), combinatorial optimization, and population mobility dynamics. These CFD models, coupled with population mobility models, faci...

Animal eyes for military and homeland security applications

While cameras, telescopes, microscopes and other imaging sensors are all instruments supporting the human eye, biologicallyinspired optical imaging systems are becoming increasingly attractive for military and homeland security applications.1 Since the development of classical optical systems, such as the Maxwell fish-eye2 and the Luneburg lens,3 with features reminiscent of fish eyes, other an...

Membrane inlet mass spectrometry for homeland security and forensic applications.

A man-portable membrane inlet mass spectrometer has been built and tested to detect and monitor characteristic odors emitted from the human body and also from threat substances. In each case, a heated membrane sampling probe was used. During human scent monitoring experiments, data were obtained for inorganic gases and volatile organic compounds emitted from human breath and sweat in a confined...
