This proposal details an approach for coupling radio channel propagation models with models of the radio frequency electronics in a transceiver to allow simulation of bi-directional channel estimation in a wireless communication system. The proposed efforts focus on exploiting the reciprocal nature of the electromagnetic propagation to reduce overhead necessary for channel feedback or to enable es ...

In order to maintain our nation’s technological superiority on air, sea and land, we must respond quicker to emerging threats and reduce the cost of major sensing platforms. Every DoD platform developed nowadays contains at least one sensor, whether it be RF, EO/IR, or acoustic. In fact, in a lot of recent developments, the platform is built around the sensor and exists only to support the senso ...

This program proposes to demonstrate an ultra-low power design methodology and circuits for digital logic employing advanced dynamic voltage scaling (DVS) for asynchronous NULL Convention Logic (NCL) circuits operating in sub-threshold to super-threshold voltage regimes. The power supply voltages of logic block partitions will be independently set by on-chip voltage controllers based on the data p ...

Investment castings have well served both the military and commercial markets in such areas as waveguides and splitters for microwave applications, and for connectors, housings, heat sinks and mechanical parts for electronics, optical, instrumentation, and medical devices. Tomorrow's higher RF millimeter wave and communications electronics products, and more compact optical, instrumentation and m ...

A critical component of a biochemical sensor system for detection and analysis of airborne pathogens are mechanisms for automated acquisition and transport of an air sample from the sensor inlet to the analysis chamber. While considerable capability already exists for sampling and handling of macroscopic volumes of gas, formidable technological challenges needed to be overcome before microfabrica ...

A novel approach to the propulsion of very small, micro air vehicles is proposed in which electrostatic forces acting between an ion gas cloud and an appropriate anode are harnessed for thrust or lift. A means is proposed for the generation and maintenance of the ion gas from ambient air and for the regulation of the propulsor. Preliminary study indicates the new concept is valid only for air v ...

A novel method for preparing carbon electrode structures having applications in electrochemical double layer capacitors (EDLCs) is described. The method for preparing these structures employs carbon (graphite) nano fiber materials and results in an electrode having both high surface area and high electronic conductivity; two essential characteristics for EDLC electrodes. The fabrication process ...

We propose to build an energy extractive Individual Portal (I-Port) to the virtual world enabling the user to traverse a large virtual workspace in a very small real space. Using a commercial exercise treadmill, this device will improve virtual training, health maintenance and evaluation, and have a large market for education, recreation, and adversarial gaming. A motion capture, energy extracti ...

Among composite materials, aluminum/graphite and copper/graphite composites are potentially leading materials for use in high-performance electronic systems. The use of aluminum matrix (Al/Gr) composites for packaging material, however, have been severely limited because of the raw material and fabrication costs of the composite. In order to produce an inexpensive packaging material that exhibit ...

CONTRACTOR WILL EXAMINE THE FEASIBILITY OF UTILIZING PULTRUSION-TYPE CONTINUOUS TAPE LAYING MANUFACTURING EQUIPMENT TO FABRICATE COMPOSITE SANDWICH STRUCTURE WINGS AND STABILIZERS FOR CLOSE RANGE AND SHORT RANGE CLASS UNMANNED AERIAL VEHICLES. DURING PHASE I A SMALL PROOF-OF-CONCEPT MANUFACTURING MACHINE WILL BE DESIGNED, BUILT, AND EVALUATED. IN ADDITION, THE QUALITY OF THE MANUFACTURED PRODUCT F ...
