The proposed optical device is a fiber-based multi-channel switch to quickly switch a fiber-coupled laser among many possible output channels to create a fiber-based fixed-array laser transmitter for next-generation NASA lidar systems. The key innovation is the use of an arrangement of electro-optic prisms created in a nonlinear optical crystal through domain reversal to direct the laser into one ...

The SSC needs a hydrogen temperature sensor that can provide high accuracy, fast response and can be operated on a superheated hydrogen (SHH2) environment. This will help prepare the SSC testing facility to support the new NASA mission for US space exploration as proposed by the President in January 2004. Here, we propose to develop an innovative, non-intrusive temperature sensor based on Spontan ...

The complexity of modern systems and the stringent performance requirements for operation and uptime suggest that optimum and robust means must be deployed to make effective use of multiple sensor suites for assessing risk, identifying system degradation, understanding how system degradation progresses to failure, etc. Global Technology Connection and Georgia Tech proposes the development of data ...

The proposed SBIR effort will employ a systems approach to develop motor/controller/screw element systems adequate for demanding launch thrust vector control and control surface actuator applications. This approach will utilize high bandwidth, high efficiency, redundant motor systems coupled with appropriately paired motor controls. The actuator system will consist of a high efficiency permanen ...

79430S Conventional, industrial polymer mixers, such as kneaders and twin screws, do not provide sufficient carbon nanotube dispersion to realize the full potential of nanotube reinforcements in polymers. Although laboratory researchers commonly disperse carbon nanotubes into solvents and polymers, only modest systematic work has been conducted to make the hardware more effective or energy effici ...

Resodyn Technologies proposes a new technology that enables the application of polyimide based cryogenic insulation with low hydrogen permeability. This effort supports the Vision for U.S. Space Exploration policy and the Exploration Systems Enterprise. This technology will benefit designers of cryogenic fuel tanks envisioned for new Earth-to-Orbit (ETO) Transportation vehicles. Specifically th ...

The availability of remotely sensed data has been improving with each new high-resolution satellite obtaining operational capability in orbit. However, the ability of commercial and government entities to efficiently share or sell this data has not kept pace. The proposed GeoSpatial data distribution system will exploit recent improvements in advanced computing environments and processing algorit ...

Using a revolutionary ion-focusing scheme developed at Mississippi State University (provisional patent filed) we will be able to design and build a compact laser based time-of-flight mass spectrometer that is capable of detecting a wide range of masses. Mass resolution of above 104 can be achieved from 300 to c.a. 70,000 Daltons and above 3000 from 20 to 1.5'105 Daltons, making it possible to ana ...

79586S Solid state lighting (SSL) is rapidly gaining momentum as a highly energy efficient replacement technology for traditional lamps. However, current devices made with solid state light-emitting diodes (LEDs) still suffer from low efficiencies, partly due to an optical mismatch between the LED and phosphor materials. Recently, a new class of phosphors were optically designed to maximize LED ...

This proposal is aimed at demonstrating the feasibility of a Decentralized Control based SiC Parallel DC-DC Converter Unit (DDCU) with targeted application for NASA's International Space Station Program and Satellite Power Systems. The proposed DDCU has three key features: a) "true" redundancy for parallel DC-DC converter based on a novel concept developed at the University of Illinois at Chicago, ...
