Facile reverse engineering of existing devices by means of 3D reconstruction is an emergent need for advanced semiconductor technologists who seek to understand product failures, to improve device design and manufacturability, and to verify as-built device compliance to specified designs. The latter objective relates particularly to trusted and counterfeit device programs. Today's barriers ...

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 ...

Mobile applications are becoming ubiquitous, appearing in many new situations. Some of these areas have specific requirements pertaining to information flow and device functionality. However, software on these devices is currently unregulated, and there are mechanisms within the mobile operating systems that facilitate unintended and undesirable information sharing as well as granting excessive co ...

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 new quasi-resonant converter, called the unipolar series resonant converter ("USRC"), will be adapted as a four-quadrant drive for electric vehicles ("EVs"). With zero current and voltage switching, it will high modulation frequency (over 30 khz), thus driving a motor silently and efficiently throughout the speed range. The USRC produces any waveform required by any type of EV motor. It produces ...

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 ...

Software design, development, and maintenance constitute a complex and time-intensive process. Early design decisions can have a crucial impact on both quality and cost. Design rationale tools have been shown to be effective in supporting this process, but are infrequently used due to their interference with normal design team workflow. The rapid growth of new network and web-mediated workstyle ...

A fundamental component responsible for low bit error rate (BER) is the phase jitter of the frequency reference source, regardless if a network is wireless or fiber optic in nature. In the case of wireless the frequency reference source is typically a voltage controlled oscillator (VCO), and in the fiber optic case it is a clock. In order to maximize the full benefit of spread spectrum technique ...

WE PROPOSE TO DEMONSTRATE THE FEASIBILITY OF OPTICAL CHARACTER RECOGNITION (OCR) ON A VLSI NEUROCOMPUTER. THE OCR SYSTEM WILL USE STATE OF THE ART ARTIFICIAL NEURAL NETWORK CLASSIFIERS ONADAPTIVE SOLUTIONS' CNAPS NEUROCOMPUTER CHIPS. THE CNAPS CHIPS OFFERUNPRECEDENTED PERFORMANCE OF ARTIFICIAL NEURAL NETWORKS. THE IMAGE PREPROCESSING OF THE OCR SYSTEM WILL ALSO EXECUTE ON THE CNAPS CHIPS. THE GOAL ...
