Award List:

THIS PROPOSAL ADDRESSES THE PROPAGATION, PERSISTENCE, AND FATE OF A VORTEX PAIR IN A STRATIFIED, SHEARES E ENVIRONMENT.

Award Year / Program / Phase: 1983 / SBIR / Phase I
Agency / Branch: DOD / NAVY
Principal Investigator:
Award Amount: $91,983.00
Abstract:
This proposal addresses the propagation, persistence, and fate of a vortex pair in a stratified, sheares e environment. in particular, we will study the evoluton of a solitary vortex which occurs when a vortex pair is imbedded in shear flow of proper magnitude. solitary waves have been observed to… More

Award Amount: $931,000.00
Abstract:
Mines buried in the sea bottom are often impossible to detect acoustically. electromagnetic energy provides an alternative means of detection. an active system formed by a source current encircling a superconductive magnetic gradiometer holds the promise of providing an underwater-towed system for… More

RAPID MEASURES OF BRAIN ACTIVITY TO ASSESS WAKEFUL ATTENTIVENESS

Agency / Branch: DOD / USAF
Principal Investigator: Dr bruce west
Award Amount: $50,024.00
Abstract:
We propose the application of a newly developed data processing technique to eeg time series. this technique will allow us to develop quantitative measures of brain activity associated with wakeful attentiveness. these measures are the fractal dimension and the information entropy both of which have… More

DESIGN AND DEVELOPMENT CONSIDERATIONS FOR AN IMPROVED AND UPGRADED WIND TUNNEL AT DPG

Award Year / Program / Phase: 1987 / SBIR / Phase I
Agency / Branch: DOD / ARMY
Principal Investigator: Dr william t kreiss
Award Amount: $49,582.00
Abstract:
The performance of atmospheric samplers is crucial to the analyses and interpretation of disposal and reaction-rate trail data for cbw materials and obscurants. routine calibration of sensor/sampler is performed prior to deployment in support of field trials. presently sensor/samplers collection… More

PULSED ELECTROMAGNETIC SYSTEM FOR AIRBORNE SURVEILLANCE OF MINES IN SHALLOW WATER

Agency / Branch: DOD / NAVY
Principal Investigator: Dr walter n podney
Award Amount: $49,435.00
Abstract:
A review of sensor technologies shows that electromagnetic energy at frequencies below 1 khz can provide a reliable means to detect, identify, and locate mines in shallow water. a pulsed electromagneticinstrument comprising a transmitter encircling a superconductive magnetic receiver promises to… More

MAGNETIC CONTROL OF CRITICAL CURRENTS IN SUPERCONDUCTING QUANTUM INTERFERENCE DEVICES OPERATING AT 77 K

Award Year / Program / Phase: 1988 / SBIR / Phase I
Agency: DOE
Principal Investigator: Dr walter n podney
Award Amount: $50,000.00
Abstract:
The squid (superconducting quantum interference device) makes possible magnetic measurements of unequalled sensitivity. heretofore, practical squid systems have been cooled by liquid helium. the problem of reliably fabricating practical, low noise squids that operate in liquid nitrogen remains… More

SUPERCONDUCTING ELECTROMAGNETIC SENSOR FOR NONDESTRUCTIVE EVALUATION OF STRESS IN METALS

Award Year / Program / Phase: 1988 / SBIR / Phase I
Agency / Branch: DOD / ARMY
Principal Investigator: Dr walter n podney
Award Amount: $52,976.00
Abstract:
We propose to develop a non-contacting electromagnetic system to measure residual stress in ferromagnetic armor plate. we use a superconductive (squid) magnetic gradiometer in a novel configuration as the sensor. it is combined with a magnetizing source consisting of a nested set of superconducting… More
