Abstract:Metal Injection Molding (MIM) partsmakers have indicated that the use of alloy metal powders currently available results in unacceptable distortion of large aspect ratio parts. This is attributed to the low "brown" strength of debound parts made with spherical gas atomized powder. This proposal… more
Abstract:The addition of Sic Platelets to selected diboride material systems offers the possibilities of increased toughness and improved Thermal protection. The innovative use of single crystal silicon carbide platelets with their highly reflective crystalographic planes, could lead to increased hot wall… more
Abstract:The dolphin has a unique sonar capability by which it produces high-frequency clicks. The dolphin is able to vary both the frequency content and the repetition rate of the echolocation clicks. The goal of the combined Phase I and Phase II project is to model the dolphin sonar and to design,… more
Abstract:To work efficiently, the flight crew of an extended duration spaceflight will need an on board device for manipulating and processing large scale (Megaplxel) image data in real time or "interactively". For large scale high resolution photographs, this interactive capability requires processing… more
Abstract:The purpose of the Phase I work is to identify the best packaging concept for the Hall Effect device and to deterinine the feasibility of building it. KVH proposes to test and characterize the NWC Hall Effect Breadboard and to generate a packaging feasibility study. KVH will use unique, proprietary… more
Abstract:KVH Industries proposes to develop a proof-of-principle Universal Driver's Display (UDD) for the Amphibious Assault Vehicle (AAV7A1). The UDD will comprise a flat-faced, color-capable screen with co-located electronics and integrated with engine sensors and the magnetic compass. We will use our… more
Abstract:WE PROPOSE TO DEVELOP OPTIMIZED, HIGH PERFORMANCE AND LOW COST FIBER OPTICAL AMPLIFIERS FOR USE IN THE 1300 NM SIGNAL WAVELENGTH. WE PLAN TO SHOW THE FEASIBILITY OF OUR APPROACH BY CARRYING OUT MEASUREMENTS IN AN ASSEMBLED LABORATORY SET-UP. WE WILL COMPARE THESE RESULTS WITH OUR THEORETICAL… more
Abstract:We propose to develop an optimized, high performance and low-cost fiber optical amlifier for use in the 800 nm signal wavelength band. The rare-earth dopant will be thulium (Tm) and the host fiber composition will be a heavy metal fluoride glass (ZBLAN). This amplifier, labeled TDFFOA, or a… more
Abstract:We propose to develop for the first time, a high performance, low noise amplifier in the 850 nm signal band using a Erbium-Terbium co-doped active fiber. Erbium-Terbium co-doped fiber optical amplifiers (ETCFOA) will be key components for short haul communication systems in the first… more
Abstract:Recent progress in the availability of low cost reinforced thermoplastic unidirectional tape provides a family of alternative composite systems for pultruded structures. Cost effective pultrusion of carbon fiber reinforced thermoplastic resins will be demonstrated in the Phase I effort of this… more
Abstract:This SBIR program is aimed at improving the power density of rechargeable cells in general, and particularly those used in underwater vehicles. We intend to achieve that objective by advancing the state-of_the-art of bipolar electrodes, where both positive and negatives are built on a common current… more
Abstract:An investigation of nickel coating processes to provide corrosion protection for 6061-T6 aluminum alloy in a marine environment is proposed. The effects of aluminum preparation and pretreatment steps will be investigated. Additionally, strategies which utilize multiple layers of nickel of different… more
Abstract:DETECTION AND MEASUREMENT OF SOOT IN THE EXHAUST OF TURBINE ENGINES IS IMPORTANT FROM A TACTICAL STANDPOINT OF AIRCRAFT VULNERABILITY. EXIS TING OPTICAL DETECTION METHODS ARE SUBJECT TO ERROR AND SUBJECTIVE ANA LYSIS. A NOVEL SOOT DETECTION METHOD IS PROPOSED FOR DEVELOPMENT. IT RELIES ON THE… more
Abstract:This project is based on a novel computer graphics technology for man/machine interfaces that relies on machine learning techniques, neural-like networks, and object recognition IU techniques. The key idea is to use a few "example" views of an object or person, to teach the computer to generate… more
Abstract:KVH Industries proposes to design and demonstrate a low cost short range acoustic buoy release system designed to locate and retrieve underwater instruments. The proposed design effort will address the problems of search rate, identification, homing, slant range measurement, localization and buoy… more
Abstract:Sapphire, and other hard brittle materials, are highly regarded as missile domes because of their high mechanical strength and thermal characteristics. Conventional finishing processes used to provide for the final configuration of the domes can be as much as 50 percent or more of the total cost. A… more
Abstract:We propose to develop an Environmental Monitoring System by integrating various technologies to create a hybrid artificial neural network system. By functionally decomposing the requirements of environmental monitoring we can apply emerging technologies to fulfill these modularized requirements. Ten… 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.
