Abstract:This proposal describes development of a new type of quantum-cascade laser for use as a local oscillator at frequencies above 2 THz. The THz source described is a single chip solution that operates at room temperature. In addition, a mechanism for wide tuning (2-4.7 THz) is described that requires… more
Abstract:High performance infrared detectors in the LWIR regime are highly needed in a number of missile defense missions. In order to image targets from long distance, it is important that imagers have high sensitivity and high resolution. This leads to technical goals of having low noise, low dark current… more
Abstract:Infrared countermeasure and standoff chemical detection applications require a light source with high power output, good beam quality, and a wide tuning range. There are a limited number of viable mid-infrared (3-5 micron wavelength) solutions that can provide these features in a compact and power… more
Abstract:Surface emitting semiconductor lasers eliminate the necessity for facet cleaving and allow for wafer scale testing, which increase the manufacturing yield and reduces the cost. However, in the mid-infrared, surface emitting semiconductor lasers are significantly underdeveloped compared to edge… more
Abstract:Existing ultraviolet laser diodes with wavelengths much shorter than 365 nm suffer from poor performance. This is partially due to limited research in this area, but a large part is also due to material and processing issues unique to deep UV lasers. New approaches to achieving 340 nm III-Nitride… more
Abstract:In atmospheric aerosol research, size-distributed aerosol samples are often collected with airborne instrumentation, but are not analyzed in any manner until after they are brought to a laboratory on the ground. The information thus obtained is averaged for all the locations covered during the… more
Abstract:DESCRIPTION (provided by applicant): This project will provide a significantly improved method for intra-pulmonary drug delivery in pediatric patients who are intubated or have a tracheostomy. Currently available aerosolizing devices are limited in that only certain agents and only a small fraction… more
Abstract:The U.S. DOE Office of Environmental Management (EM) was created in 1989 to manage the cleanup of large areas of environmentally contaminated sites. Since the closure of many of these sites, U.S. taxpayers have spent about $220 billion at 74 cleanup sites. However, these sites were the smallest and … more
Abstract:The Phase I verified ADS-B-ER feasibility-based on compatibility with the ADS-B operational standards and design specs, bandwidth and the iPAD EFB capability for performing the trajectory computations for avoiding hazardous weather, terrain, traffic and restricted airspace. We then assured that… more
Abstract:Thomas Jefferson National Accelerator Facility (JLAB) currently uses low efficiency klystrons, with a system of 340 klystrons approaching an MTBF of 170,000 hours. But over the lifetime of the project 60% of the tubes have been replaced, giving an MTBF for a single tube of about five to six years. … more
Abstract:S-Band vacuum loads at the SLAC linac are encountering operational problems now that they have to operate under the stringent requirements of the LCLS: 50 MW peak power, 6 kW average power, and extremely tight phase stability for the linac. Failure mechanisms have been studied which suggest an RF… more
Abstract:This Phase I SBIR program will define the requirements and the development plan for a broadband monolithic microwave transceiver integrated circuit which will enable the production of the next generation of precision end-game proximity sensors suitable for deployment on low-cost high-volume… more
Abstract:Mustang proposes to develop innovative, low Size, Weight, and Power (SWaP) Digital Receiver Exciter (DREX) technologies needed for simultaneous operation of the U.S. Navy Fire Scout Radar Autonomous Collision and Avoidance System (RACAS) and Coherent Automatic Radar Periscope Detection and… more
Abstract:ABSTRACT: Mustang Technology Group, LP is proposing a Phase I SBIR study that will expand the capability of air delivered weapons by providing a low cost, small form factor, multi-function radar seeker which has a flexible architecture which supports multiple radar modes and high speed data link… more
Abstract:In the domain of language, infants and young children are superior learners when compared to adults, in spite of adults'cognitive superiority. Language is one of the classic examples of a''critical''or''sensitive''period in neurobiology. Children who… more
Abstract:Timing and position data from civil GPS receivers have become integral to the operation of many of the Nation's critical infrastructures. Through the
Patriot Watch architecture, DHS is coordinating efforts to identify, locate, and attribute domestic GPS interference, maintain a central database… more
Abstract:Under this proposed effort, we plan to test the feasibility of adapting our terrestrial jammer locator system (JLOC) to locating jamming signals in space by adapting our previously developed GPS software defined radio (SDR) technology to provide an SDR waveform that can operate on spacecraft to… more
Abstract:ABSTRACT: The biggest demand on a military receiver has been from the time required to search and acquire for the military signals when an accurate internal time reference is not available. Prior research by NAVSYS into network assisted GPS approaches used the JTRS network itself to transfer time… more
Abstract:ABSTRACT: A robust back-up navigation alternative is needed to continue to provide accurate PVT data when GPS is denied. Navigation solutions can be enhanced by utilizing existing networked communications for dismounted forces operating in small platoons. When some of the forces lose their GPS… more
Abstract:This Small Business Innovation Research (SBIR) Phase I project seeks to develop a method for the production of polycrystalline YAG laser gain media containing gradients of dopant in either linear or radial directions within the part. Such parts offer performance improvements for both output power… more
Abstract:Wet clothing and footwear creates discomfort and can impede performance and morale for DoD personnel. During the Phase I research period a portable, reusable, light and efficient method to accelerate the moisture removal from difficult to dry pieces of clothing such as combat boots will be developed… more
Abstract:During the Phase I Research Period we will develop a high porosity, nanoengineered filtration material that couples high filter efficiency with a very low pressure drop.

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.
