Abstract:As adversarial submarines become quieter and operate in increasingly adverse acoustic environments, the U.S. needs effective non-acoustic detection capability deployed from maritime patrol aircraft. Air-dropped buoys exploiting submarine ELF emmissions offer unique advantages over MAD and other… more
Abstract:Littoral METOC products are required for planning efficient and safe expeditionary warfare operations in the littorals. Present Navy programs are addressing long- and medium-term solutions for acquiring these products, but these solutions require modest-size or larger theater or national systems to… more
Abstract:Arete Associates' is proposing to develop a hyper-spectral, IOP sensor system that can be deployed by a variety of means in the surfzones of forward areas. It will measure, record and report IOPs that are vital to naval MCM operations. The sensor system will be inexpensive enough to be expendable,… more
Abstract:In Phase II of this SBIR program, Arete Associates proposes to demonstrate the Inboard Magnetic Quieting System (IMaQS) and develop the Electric Magnetic Matched Field Tracker (EMMFT) as two complementary aspects of a next-generation magnetic anomaly detection (MAD) system that will enable… more
Abstract:Monitoring bathymetry changes in shipping channels of rivers and estuaries is vital to the US economy. The standard method of sonar depth sounding from survey ships, though accurate, is slow to perform. Thus, we propose a new and innovative approach for rapid assessment of shipping channel… more
Abstract:The objective of the proposed program is to develop a long term image-based tracking camera system. Our goal is to allow fewer personnel to analyze and respond to threats detected in aerial video, making large format video useful in real time analysis. We propose to exploit long term 'contextual' … more
Abstract:We will develop an efficient tool for formal verification of PowerPC 750 executables. The PowerPC 750 architecture is used in the radiation-hardened RAD750 flight-control computers that are utilized in many space missions. The resulting tool will be capable of formally checking: 1) the equivalence… more
Abstract:DESCRIPTION (provided by applicant): The long-term goal of this project is to develop an effective therapy against relapsing vaginosis caused by Candida albicans. The disease occurs in 8-9% of all women, and is recalcitrant to currently available therapies
. Upon adherence to a surface, C. albicans… more
Abstract:DESCRIPTION (provided by applicant): The work performed in this proposal will help in the development of tissue engineered cartilage constructs, to be commercialized as the TEC-AriTM method. The product is intended to be a tissue engineering service avail
able to health care providers that involves… more
Abstract:APEI, Inc. is proposing to develop a low profile, non-intrusive, high temperature (300 degrees C) bearing data transmitter system that will allow the in-situ monitoring and diagnostic of bearing health. The proposed high-temperature data transmitter system will be built on high temperature… more
Abstract:Advances in radar systems are pushing the limits of present radar power supply technology. To enable new concepts, such as active array radar systems, significant improvements (i.e., power densities >200 W/in3, efficiency > 90%, transient response < 10 s, etc.) in radar power supply technology is… more
Abstract:This Small Business Innovation Research (SBIR) Phase I project seeks to develop an advanced flexible self-powered robust high power density solid-state circuit breaker (SSCB) through the incorporation of emerging silicon carbide (SiC) device technology and the implementation of advanced thermal… more
Abstract:This project will develop high-voltage, high-performance Solid-State Fault Current Controller (SSFCC) technology, needed to minimize recovery time and vulnerability of the electricity network in the event of a large-scale natural disaster. The SSFCC technology, which utilizes Silicon Carbide (SiC)… 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.
