A fast-pulsed (3-15ns FWHM) high-current (>500A) driver for high power diode lasers or laser arrays is proposed. Present high-current diode drivers typically use MOSFET switches to modulate the current. It is difficult to achieve very fast pulses with such devices because the inherent capacitance of the gate electrode cannot be charged and discharged quickly. Lower current, but faster diode driver ...

THE SUMULATOR WILL BE DESIGNED FOR OPERATOR TRAINING ON ADVANCED REACTORS AND WILL BE USED IN SIMULATING OPERATORS SCENARIOS AND RECORDING AND DOCUMENTING REAL-TIME INPUT FROM THE OPERATOR. THE SIMULATO ...

SEEKER STABILIZATION VIBRATION SUPPRESSION ELECTRO-ACTIVE MATERIALS PROPULSION RESEARCH WILL USE ITS MINIATURE "FERRO-MAGNETIC" ACTUATOR EFFORTD CAN BE USED TO CREATE A "SEEKER ANTI-MOTION SYSTEM". THIS TECHNOLOGY TAKES AN AGGRESSIVE APPROACH TOWARD "INTELLIGENTLY" MANAGING THE SEEKER DYNAMIC RESPONSE TO INDUCED MOTION BY ISOLATING IT "DYNAMICALLY" FROM THE REAMINDER OF THE AIRFRAME USING ELECTRO- ...

An adaptive attitude control system for a space-based interceptor will ameliorate the effects of torque disturbances when firing a divert thruster with the line of force offset from its center of mass. The adaptive control algorithm is based on a simplified version of a model reference adaptive control concept. It possesses two features: (i) more robust performance for the interceptor guidance and ...

Adaptive spatio-temporal filtering methods are proposed which are inherently suitable to utilizing many sensors and actuators to achieve superior control and monitoring of structures for vibration and shape control and damage detection. When utilizing large numbers of sensors and actuators, failure detection and failure recovery become important issues. The adaptive spatio-temporal filtering metho ...

This proposal addresses the exploratory development and evaluation of novel thin film and/or monolithic detonators as diverters for guided spinning projectile use. A number of such detonators comprise a diverter technology termed RMDM, (for Ring Matrix Diverter Module) which, along with the SSPG (for Small Spinning Projectile Guidance) seeker, forms the basis for inexpensive miniature guided proje ...

A significant need exists for power switching transistors used in spacecraft power management and distribution (PMAD) modules which can operate at high temperatures (400 C). SVT Associates proposes to meet-the need for high temperature electronic devices with an innovative large gate-width GaN junction field effect transistor (JFET). The Phase I program will demonstrate transistors based on N and ...

We offer an approach to a multiple-order-of-magnitude processing speed/efficiency improvement in vector quantization (VQ) data/image compression, automatic target recognition/classification, and time signal/signature classification. We base our approach on an algorithmic breakthrough, the TABULAR NEAREST-NEIGHBOR ENCODER (TNE), which we discovered and partially developed last year. This algorithm ...

The results of the proposed Omni-Directional Sensor Mount research and development will be greater usefulness of both old and new Ballistic Missile Defense Organization (BMDO) sensor technology. The innovative design adapts novel patented and patent pending technology, to provide a double-jointed sensor mount which is singularity and gimbal lock-free. The device merges novel patented technology wi ...

The development of a microwave curing method for resin matrix composites and jointing/bonding epoxy is proposed. This technique will take advantage of the ability of vapor-grown carbon fiber (VGCF) to absorb microwave energy with high efficiency. By adding VGCF to resin matrix composite material and epoxy, we hope that the materials can be processed by microwave irradiation in a manner that result ...
