MANY PRECISION POINTING AND TRACKING SYSTEMS OPERATE IN VIBRATION ENVIRONMENTS THAT REQUIRE VIBRATION ISOLATION TO CHIEVE DESIRED PERFORMANCE. ACTIVE VIBRATION ISOLATION SYSTEMS UTILIZING HIGH-FORCE CAPABILITY, NONLINEAR MAGNETIC ACTUATORS ARE A PROMISING MEANS OF ACHIEVING THE REQUIRED HIGH PERFORMANCE VIBRATION ISOLATION. THEIR DESIRABLE CHARACTERISTIC INCLUDE HIGH BANDWIDTH, HIGH-FORCE CAPABILI ...

The optical sensor aboard the Exo-atmospheric Kill Vehicle (EKV) needs to generate multispectral long-wave infrared (LWIR) images in order to distinguish the re-entrant vehicle from decoys within the threat cloud and the interfering scene clutter. The spectral signatures collected contain information on surface emissivity and target temperature, both important parameters for discrimination algorit ...

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 ...

Engagement simulation models provide an indispensable tool for the design of sophisticated missile defense systems. This requires treating real-time motions and the complex scattering physics of active laser interactions with plume and debris fields from hardbody/plume transient events. Spectral Sciences, Inc., in collaboration with Kinetics, Inc and Photon Research Associates, Inc., proposes to ...

MEMS accelerometers typically use force/torque rebalance applied by subcomponent actuators which, although well-understood, are seriously limited in performance by fundamental material and electronics stability issues, and some subcomponent design issues. These deficiencies can be overcome by the introduction of "gyro-rebalance", which substitutes inertial force balancing (the use of gyro torque t ...

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 ...

A NEW SYSTEM, THE ANNULAR FLOW ELECTROTHERMAL PLUG RAMJET, IS PROPOSED AS A ALTERNATIVE TO CHEMICAL ROCKETS AND ELECTROMAGNETIC LAUNCHERS AS A KINETIC ENERGY WEAPON. THIS SYSTEM APPEARS TO BE CAPABLE OF ACHIEVING THE HYPERVELOCITIES NECESSARY IN REASONABLE LAUNCHER LENGTHS, PRIMARILY BECAUSE IT DOES NOT ACCELERATE EITHER THE PROPELLANT OR THE PROPULSION SYSTEM REQUIRED TO ACHIEVE HYPERVELOCITIES. ...

We investigate the development of a secure fuselet runtime environment built on a foundation of aspect-oriented web services. Aspect-oriented techniques enable the modularization of crosscutting concerns such as remote access, security, and monitoring using code instrumentation. We compose aspect-oriented instrumentation with web service technologies in a noninvasive and orthogonal manner, and lev ...

This effort is based on the outcome of a successful Phase I project that demonstrated the feasibility of generating logic pattern-based, OS-platform-independent, signatures for malicious program logic and detecting its presence within much larger binary modules. The detection (and localization) of a logic-based signature within a binary executable represents a significant advancement in automated ...
