Secure broadcasting mechanisms play an important role in satellite-based communications networks. In this Phase I SBIR project, Artery Communication Technology Inc. proposes a scalable secure data broadcasting architecture that is both bandwidth efficient and as secure as state of the art public key cryptosystems. The major emphasis of this project is to analyze the detailed performance behavior ...

DOD's plan to make all U.S. military equipment run on a single fuel, logistics fuel, has obvious logistics advantages, but will require replacement of spark ignition engines with diesel engines or gas turbines. Both diesel engines and gas turbines are systems which must be operated fuel lean. Consequently, the three way catalyst system used in automobiles can not be used to control their emissio ...

We propose to develop a novel high speed, frequency controlled, single mode semiconductor laser based on planar ring resonator geometry. The technique utilizes electromagnetic fields interference effects within a coupled circular cavity to selectively shape the spectrum and determine the operating frequency of the laser. Unlike its counterpart distributed feedback (DFB) the ring resonator laser ha ...

A novel concept is proposed for a laser spectrometer for measuring trace amounts of chemical species. The spectrometer will be based on a unique laser source that is continuously tunable in the infrared from 3.7 to 11 um and which possesses spectra output linewidth on the order of 0.01c,1. The extremely high spectral brightness of the laser source will allow high sensitivity and accuracy. The v ...

Electromechanically Actuated (EMA) valves are generally defined as valves operated by electronically controlled motor drive systems, rather than by valved hydraulic or pneumatic systems. Morotta Scientific Controls reviewed the current state-of-the-art for EMA ball valves in the cryogenic rocket propulsion industry and performed a trade study comparing these valves to a new and innovative valve d ...

High performance, high gain, uncooled detectors and detector arrays working at eye safe wavelengths are necessary or the development of low cost laser radar systems for imaging and targeting applications. Imaging arrays with the capability of acquiring and processing true time delay information at the pixel level for ranging is extremely important for obtaining the 3D imagery with laser radar sys ...

Based on our experimental results, we propose to develop technology to remove biofilm from DUWS tubing. PTT approach is based on a combination of engineering, proprietary/safe cleaning formulation, and validated treatment protocol. This technology is capable of physically removing the biofilm from dental tubing. PTT's technology is compatible with the design of the dental unit and utilizes its ...

Working to achieve two level avionics maintenance, USAF would like to provide maintenance technicians with a portable RTS to perform go-no-go tests on current (and planned) airborne communications (comm) equipment.This compability would substantially reduce the number of "no fault found" equipment removals and, thereby, the amount of investment in equipment in the logistic chain; this compatiblity ...

The main objective of this Phase I program will be to develop bagging and/or sealant formulations for use with high temperature (>650F) curing of aerospace quality advanced composite structures. Our main approach will be to formulate a high temperature processable resing system by investigating improvements of silicone rubber, fluoropolymers, polyimides and combining the chemistries of ...
