A DESIGN FOR A RUGGED, HIGH-FREQUENCY, ACCELERATION-INSENSITIVE AIRBLAST GAGE IS PROPOSED. THE PROPOSED GAGE SHOULD HAVE ITS FUNDAMENTAL VIBRATION FREQUENCY ABOVE 400 KHZ, BE ROUGHLY CYLINDRICAL IN SHAPE WITH DIAMETER AND LENGTH BOTH LESS THAN ONE INCH, AND HAVE BUILT-IN COMPENSATION WHICH WILL LIMIT SPURIOUS SIGNALS DUE TOACCELERATION TO VERY LOW LEVELS. FULLSCALE OUTPUT FOR AN APPLIED AIRBLAST P ...

N/A

IT IS PROPOSED TO UTILIZE A GAS DENSITY DETECTOR FOR PROFILING GASES ENCOUNTERED IN THE HELICOPTER ENVIRONMENT. THE DETECTOR, COUPLED WITH AN APPROPRIATE GAS CHROMATOGRAPH COLUMN, HAS BEEN PROVED IN IDENTIFYING AND QUANTIFYING INDIVIDUAL COMPONENTS IN COMPLEX GAS MIXTURES. THE GAS DENSITY DETECTOR GIVES A RESPONSE THAT IS A FUNCTION OF THE DIFFERENCE IN DENSITY OF THE SELECTED CARRIER GAS AND THE ...

THIS PROPOSED PROGRAM IS TO INVESTIGATE THE FEASIBILITY OF USING UNIQUE FILTERING TECHIQUES TO PROCESS PULSE-TO-PULSE RCS AND PHASE DATA TO TRACK AN AIR VEHICLE IN THE PRESENCE OF CHAFF. THE PROPOSED TECHNIQUE WOULD PERMIT TRACKING THE AIRCRAFT WITH OR WITHOUT THE PRESENCE OF CHAFF. IT IS ANTICIPATED THAT THIS INSTRUMENTATION COULD BE ADDED TO ANY COHERENT OR SEMI-COHERENT RADAR AND BE FAR SUPERIO ...

N/A

AN EVALUATION OF AVAILABLE EXTENDED-WEAR HYDROGEL CONTACT LENS FOR POSSIBLE USE BY MILITARY AIRCREWS UNDER COMBAT CONDITIONS. THIS EVALUATION WILL QUANTITATIVELY AND OVALITATIVELY CHARACTERIZE EACH SUCH LENS AGAINST DOA PROVIDED MILITARY REQUIREMETNS. THE RESULT WILL BE THE SELECTION OF A FAMILY OF LENSES FOR FURTHER CLINICAL AND FIELD INVESTIGATION AND EVALUATION.

Nanohmics Inc. in collaboration with Dr. Andrea Al propose to develop and experimentally demonstrate ultra-compact nonlinear-plasmonic all-optical switches and isolators that exploit sharp asymmetric plasmonic-resonances observed in sub-wavelength metasurfaces. Devices will be comprised of plasmonic gratings that couple light into Long Range Surface Plasmons (LRSPs). The gratings are engineered to ...

This STTR will develop atomically precise fabrication and measurement technology that will enable a new experimental regime to study the physics of strongly correlated quantum systems.The fabrication techniques are based primarily on Hydrogen Depassivation Lithography (HDL) which uses Scanning Tunneling Microscope technology to create atomically precise patterns of H on a Si (100) 2x1 surface in a ...

To reach the end user, oil and gas production at the wellhead must be transmitted through the country and distributed to a wide range of customers. This logistical system requires natural gas gathering lines, processing facilities, product storage tanks and lots of other equipment. What results is air pollution caused by industry losses during these operations and the use of continuous or intermit ...

We will develop a lab-on-chip optical absorption spectrometer spanning 3-15micron molecular fingerprint region, in a single epitaxially grown heterostructure that monolithically integrates thermally tuned distributed feedback quantum cascade laser (QCL) and quantum cascade detector (QCD) arrays with slotted photonic crystal waveguides (SPCWs) in a mid-infrared InGaAs passive photonic waveguide.
