Abstract:In this effort, Physical Sciences Inc. will develop and implement algorithms and hardware to perform the fusion of information obtained from multiple LWIR passive hyperspectral sensors to provide the capability to determine the extent, absolute geo-location, and 3-D concentration distribution of… more
Abstract:ABSTRACT: In collaboration with Sandia National Laboratory, Physical Sciences Inc (PSI) proposes to design, develop, and demonstrate a Frequency Agile Terahertz Sensor (FATS) for trace explosives residue detection. The critical frequency agile terahertz (THz) detector is based on an electronically… more
Abstract:SOCOM and other DOD services have urgent need for safe, non-toxic visual obscurants that can be rapidly dispersed in a battlefield or into a vehicle. These obscurants must block or disrupt all visual capability within their area of effect. The dispersion must be rapid and easy to implement by field… more
Abstract:Physical Sciences, Inc. (PSI) has demonstrated that electroactive polymer coatings (EAP) may be applied to the surface of the cathode materials for lithium-ion batteries to protect against catastrophic cell failure. These EAP coatings form an electrochemical"switch"that can prevent… more
Abstract:Physical Sciences Inc. (PSI) proposes to develop validated plume codes for the hydrazine monopropellant thruster; the propulsion system that is being utilized for the Divert Attitude Control system in the kill-vehicles in several MDA sponsored defense systems. In Phase I, PSI demonstrated an… more
Abstract:Physical Sciences Inc. (PSI) proposes a data-driven, multi-tiered, object-based approach to clutter and debris suppression during BMD engagements. Using models and signal processing innovations for clutter and debris developed during the Phase I program, improvements to the current and future… more
Abstract:PSI proposes a development program targeting several significant advances in track correlation algorithms to address ballistic missile defense threats such as medium to large sized raids in the context of the C2BMC. These algorithms manage the cooperation and data fusion between multiple BMDS… more
Abstract:In this Phase II SBIR proposal Physical Sciences Inc. (PSI) describes the development a solid-state emitter package to replace the propellant-based candle of the M278 infrared flare. Propellant combustion in the current candle technology is unsteady, resulting in variations in the illumination… more
Abstract:Physical Sciences, Inc. (PSI) has demonstrated the low cost fabrication of chopped carbon fibers with a 100 nm thick, continuous conductive copper coating for use as millimeter wave and infrared obscurants. The thickness, conductivity and surface roughness of the copper coating were controlled using… more
Abstract:In this Phase II SBIR proposal Physical Sciences Inc. (PSI) describes the development of an instrument for 50 meter stand-off detection of chemical, biological and explosive (CBE) residues on surfaces. The system includes an illumination source to heat and desorb thermolysis products of contaminants… more
Abstract:Torpedo sonar systems will soon be capable of operating over much wider bandwidths than previously possible, enabled by technology insertions with improved transducers, T/R electronics, and signal processors. The numerical modeling performed in the Phase I program suggests that a class of wideband… more
Abstract:Physical Sciences Inc. (PSI) proposes to design, fabricate, and deliver two fully operational prototype total field scalar magnetometers with size, weight, and power specifications consistent with anti-submarine warfare (ASW) applications. The Phase II development program will extend the successful… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
