Abstract:This project proposes the use of non-imaging optical measurement to discern the weld pool oscillations occurring during electron beam deposition, and thereby to infer the weld pool size. By knowing this weld pool size, it is possible to control the e-beam deposition process by suitably regulating… more
Abstract:Existing M&S engineering tools fail to accurately model new weapons lethality enhancing (LE) phenomena so new a fast-running endgame lethality simulation program was developed. During Phase I fragment flood loading (FFL) effects were successfully incorporated into the Tesla Lethality Simulator and… more
Abstract:This proposal considers the relationship between critical thinking skills and interpersonal skills and proposes R&D agenda which will merger and integrate these two important area. The result of this work will be a training program which advances the tra
Abstract:The Missions and Means Framework (MMF) has been primarily used to examine and develop combat operation models that examine the matching of military tasks associated with the combat operations in question with the military means needed to successfully achieve those objectives. For a military… more
Abstract:First responders operate in challenging acoustic environments where noise, alarms, engines, radio communications, and communications to others in the environment make voice communications with hands-free, voice operated switch (VOX) operation
difficult. Broad Digital will use a combination of… more
Abstract:There is ample evidence that training infantry in a realistic environment is beneficial; however there is not an easy transition path due to the complexities of interfacing with a mobile soldier. Although there are many challenges, the most difficult ones to overcome are that an augmented reality… more
Abstract:Night vision has been a key enabling technology for the past 30 years that has allowed US pilots to own the night. In many engagements, our dominance of the nighttime environment was the decisive factor in victory. One of the big disadvantages of night vision systems is that they have not provided… more
Abstract:Motion blur or smear can limit the performance of liquid crystal displays (LCDs). Its cause is attributable to two main factors the relatively slow LCD response time and the non-impulse (sample-and-hold) nature of LCD pixel addressing. The first effect causes the image from one frame to persist into… more
Abstract:SA Photonics is pleased to propose the development of the Topaz modulated optical source for underwater sensing and communication. The unit will emit mulitple watts of blue light in the 450-460 nm for deep water transmission and on key Fraunhofer lines for solar noise reduction. The unit supports… more
Abstract:The current integrated missile harness fairing assembly (IMHFA) is thick, heavy and hard to maintain due to the large number of copper signal and power cables involved. SA Photonics' LightCables architecture replaces all signal cables with one or more fiber optic cables terminated by a signal… more
Abstract:SA Photonics is pleased to propose the COMET modular satellite laser system. The system integrates tunable laser diodes, fiber amplification, and wavelength division multiplexing to produce a highly flexible and scalable light source suitable for satellite communication and sensing needs. BENEFIT:… more
Abstract:SA Photonics has demonstrated the ability to develop a low cost, small form factor, high performance Fiber Optic Gyro using advanced light source technology and high performance noise reduction. The key focus of the proposed Phase I is to extend the technology to enable very small and lightweight… more
Abstract:Due to the high cost and long lead time of space based thermal management systems, there is an increased need for a space qualified thermal network system which can maintain critical components within an acceptable range during operation and be flexible in design to adapt to a wide range of… more
Abstract:During this Phase I SBIR Program, SA Photonics has demonstrated the ability to develop a low cost, small form factor high performance Fiber Optic Gyro. The key focus of this program was to both reduce the size and the cost of this assembly, while maintaining performance to the level of navigation… more
Abstract:Radar Warning Receivers (RWRs) are an integral part of Tactical Aircraft Protection Systems and are used to quickly detect imminent threats so that countermeasures or other actions can be used to avoid attack. Threat Radar signals include pulsed Doppler signals with typical carrier frequencies from… more
Abstract:SA Photonics ia pleased to propose a system approach to solving the issues that come with measurement and analysis of Phased array jamming systems. Our system, SPARC (SA Photonics Phased Array Characterization System), includes 4 main elements; The probe sub-system (photonic based signal acquisition… more
Abstract:There is increasing need for arbitrary RF waveforms with very wide instantaneous bandwidths for defense and commercial applications. Standard electronic approaches have limited bandwidth and are sensitive to electromagnetic interference. Photonic approaches are believed to be the solution because… more
Abstract:SA Photonics is pleased to propose the development of a hybrid LIDAR/RADAR receiver. The SA Photonics implementation incorporates a very high gain and low noise photonic detector. SA Photonics will integrate low noise, high dynamic range electronics with the photodetector to provide maximum… more
Abstract:A dc-dc converter with integrated Magnetics and sensor and ZVS, ZCS circuit topology in one package to reduce the interconnects and the losses is proposed. The custom made three dimensional magnetic design will allow us to increase the switching frequency to >500kHz, while maintaining >92%… more
Abstract:A network of the Distributed exportable power Generation "DG" with each DG capable of having local power and energy management. The main power and energy control is based on the real time power generation and the reserve capacity of the DG unit. All DG units communicate via CAN J1939 with local and… 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.
