We will integrate an existing evidence-based transition to… more
Abstract:An innovative"4StepPlus"three-dimensional braiding method is proposed for fabricating composite fiber preforms having solid, non-uniform cross sections. The method allows braid unit cells to be individually activated and deactivated after each braiding cycle for applications where changes… more
Abstract:In this SBIR project Wagner Associates will develop innovative: (1) hull array passive signal processing (providing more accurate bearing, narrowband frequency, and signal-to-noise (SNR) data), (2) passive state estimation, (3) torpedo launch platform localization, and (4) enhanced data fusion,… more
Abstract:ABSTRACT: In this SBIR project, Daniel H. Wagner Associates, Inc. will develop a cloud-based infrared (IR) data management capability for the Air Force, which we will name CIRRUS, short for Cloud-based IR Remote User Services. CIRRUS will provide high-performance IR data management on the Secure… more
Abstract:In this Phase II SBIR project, Daniel H. Wagner Associates (DHWA), with NASA"s Jet Propulsion Laboratory (JPL), MARK Resources, Inc. (MRI), and Spatial Integrated Systems (SIS) as our subcontractors, will develop a prototype lightweight, low-cost Wave Detection, Prediction, and Reaction System… more
Abstract:Medical imaging and targeted therapy are the central components in the clinical management of cancer patients. Rockland Immunochemicals, Inc. is teaming up with Abzyme Therapeutics LLC to develop novel imaging agents that can be used in both cancer diagnosis and targeted therapy. In this phase I… more
Abstract:Although footwear science has made considerable progress in the last decade, a performance gap continues to exist between standard issue military footwear and expedition footwear available on the commercial market. While the provision of in-shoe foot orthoses (ISFOs) is commonplace in commercial… more
Abstract:DESCRIPTION (provided by applicant): This Phase II SBIR proposal describes a strategy and work plan for accelerating to market a new device that will provide an evidence-based, patient-specific solution to a significant public health problem: foot pain. The TrueContour(R) therapeutic insole system… more
Abstract:ABSTRACT: While developing any complex system, there are invariably tradeoffs among requirements; system performance, system architecture, cost, schedule, risk, standard compliance, and other factors that decision-makers need to address. A team of experienced system engineers can be leveraged to… more
Abstract:As complex systems develop, there are inevitably changes to requirements and the system models as the team members formulate a more clear understanding of the customer needs and possible solutions. Often these changes are not coordinated since it is difficult to predict how one change may affect… more
Abstract:The CommLift Vertical Take-Off and Landing (VTOL) Unmanned Aerial Vehicle (UAV) is an alternate and novel approach to providing long range, over-the-horizon, communications for surface vessels; it uses a tethered electric UAV to carry a radio payload to suitable altitude, rather than an aerostat.… more
Abstract:DRS Scientific proposes a new type of Acousto-Optic Tuned Filter (AOTF) polarimetric hyperspectral imager that is compact, rugged, and inexpensive, has no moving parts, is free of optical aberrations, and is fast and sensitive. It will cover 8-12 mm with 8 cm-1 spectral resolution or finer, and… more
Abstract:High performance motors, like those in hybrid electric vehicles, use high performance Nd-Fe-B magnets that contain up to 12 wt% of dysprosium (Dy) in order to increase the coercivity, and avoid demagnetization at elevated temperatures. However, the global rare earth elements (Nd, Dy, etc) supply… 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.
