The SCAND concept improves network system security by increasing the efficiency of human administrators and narrowing the window of opportunity for malicious users to exploit vulnerabilities in network systems. This is achieved through the monitoring and auditing of system security configurations on large-scale, mission critical network systems. The SCAND system uses software agents to compare t ...

Communications systems depend on the health of their equipment and components to perform reliably over extended periods of time. Maintaining the health of equipment in remote, unmanned communications terminals is critical, because unscheduled repairs have significant impact on system availability. In Phase I of this SBIR project Instrumental Sciences, Inc. (ISI) researched methods to improve the e ...

Lithium oxyhalide batteries offer energy densities several times higher than thermal batteries. Like thermal batteries, lithium oxyhalide batteries have unactivated storage lives in excess of 20 years and are mechanically rugged. Some of the main advantages that lithium oxyhalide batteries offer are flat discharge voltage profiles and potentially long operating lives. However, battery performanc ...

ABSTRACT: Several new high-power, long range radar systems are under development for near-term upgrades or fielding by MDA, Navy, and Marine Corps, which will use High Voltage GaAs or new WBG Semiconductors (SiC, GaN) in the transmitter/receiver. These systems will require compact, efficient, temperature tolerant power supplies and converters typically requiring a 600 V class of power devices. ...

The projected cost for the Mentis Sciences, Inc., (MSI) prototype PAC3 radome is 1/6th of the total cost of the present system. A Pareto analysis of the current MSI process indicates that the two largest costs in radome production are the direct labor associated with fabrication and the cost of the raw materials. In Phase I MSI demonstrated that COTS paint spraying technology reduced the direct ...

Ultra-high performance multi-function RF electronics are required by the United States Department of Defense to enable next generation radar and sensor networks in response to an increasingly diverse array of threats to our military and our homeland. An elegant potential solution is that of gallium nitride (GaN) RF electronics, which has shown great promise on currently available yet foreign subs ...

Advanced space-borne infrared detectors require cooling at temperatures near 10 K. Cooling loads for these detectors will range from 0.25 W to 1.0 W at 10 K, with additional loads at higher temperatures. A multistage cooler, capable of cooling multiple loads, will offer large potential gains in system efficiency and weight. Turbomachine-based Brayton cryocoolers are ideal candidates for these m ...

DNA microarray technology, in combination with statistical and predictive modeling tools, could be used to evaluate thousands of genes against distinct gene expression patterns induced by chemical/biological agents to provide early identification and speed therapeutic intervention. The overall objective of this Phase II effort is to leverage existing public domain resources and commercial tools t ...

Radiance Technologies proposes to design and implement a PC-based Laser Radar (LADAR) Scene Generation System. The system architecture will support flexible configuration of the computational elements and subchannel rendering elements within a parallel graphics system. The scene generation system will interface, at a minimum, with the RT-Champ and RT-Flites government sponsored scene simulation co ...

The Dielectric Enhanced Resonator Antenna (DERA) program helps to meet critical missile defense system needs by employing dielectric resonators as a radiating element in radar antennas. Antennas based on this technology have many advantages over traditional microstrip antennas including: increased field of view, greater bandwidth, greater power efficiency, smaller size, higher power handling capab ...
