Portable, Rapid-Test Fuel Tank Leak Detection System
This portable system is used in tanks of 50,000 gallons or less, and helps avoid cleanup costs for undetected fuel leaks.
In 1988, the EPA issued Underground Storage Tank (UST) regulations for fuel storage in order to implement monthly monitoring and annual tightness testing. Monthly monitoring requires that the leak ...

Outdoor Synthetic Aperture Acoustic Ground Target Measurements
Sound wave reflections distinguish between various substances.
A novel outdoor synthetic aperture acoustic (SAA) system consists of a microphone and loudspeaker traveling along a 6.3-meter rail system. This is an extension of a prior indoor laboratory measurement system in which selected targets were insonified while suspended in air. ...

Uncooled Tunable LWIR Microbolometers
These devices can be placed in handheld units, modified cell-phone cameras, rifle sights, and other devices for real-time chemical sensing and target recognition.
Uncooled infrared detectors have significant potential capabilities that have been little explored. Micro-machined uncooled detectors with tunable spectral characteristics across the long-wave infrared (LWIR, λ~8-12 μ...

Fluid Helmet Liner for Protection Against Blast-Induced Traumatic Brain Injury
This liner can be used to mitigate shock waves that cause traumatic brain injuries such as blast-induced trauma.
An Advanced Combat Helmet liner design uses the novel idea of including filler materials inside channels in the liner. An energy-absorbing foam was selected for the main liner structure, and ...

Performance of Steel Stud Walls Subjected to Blast Loads
Analyses and laboratory tests measure steel stud behavior in wall systems subject to blast loads.
Construction trends have brought about an increase in the use of cold-formed steel studs in Air Force facilities. These steel stud walls have significant potential for mitigating large blast events. The current state ...
