Applying Reconfigurable Computing to Acoustic Sensors Using FPGAs
A hybrid-computing architecture using FPGAs collects, processes, and reports data from acoustic and other sensors.
A novel microsensor processing architecture allows a field-programmable gate array (FPGA) to act as a reprogrammable preprocessor or coprocessor to a general-purpose processor (GPP). The FPGA does most of the computationally complex pieces of the algorithm, while the GPP is lightly ...

The Delta-Sigma modulation technique meets the demanding requirements of future radar applications.
A prototype Digital Waveform Generator (DWG) in the ultra-high-frequency (UHF) range uses Delta-Sigma (Δ−Σ) modulation techniques, which permit arbitrary and accurate waveform generation. The DWG meets the demanding and diverse waveform requirements of future ...

NERDs can control robots, communications/GPS modules, and intruder-detection systems.
Network Enabled Resource Devices (NERDs) combine the most common electronic components used in robotic applications into a standard electronics box with “plug-n-play” capabilities. Risk reduction efforts, systems testing and integration, and modifying the functionality of evolving ...

A network provides both positioning and communication services.
Software-defined radios (SDRs) are being developed to provide positioning and communication (POSCOMM) services inside buildings and tunnels, under tree canopies, and in other environments in which local radio- communication systems are accessible but Global Positioning System (GPS) signals ...

Progress has been made toward realization of practical polymer semiconductor devices.
A three-year research project encompassed multiple studies of (1) polymer semiconductors that exhibit relatively high electric-charge- carrier mobilities and (2) applications of these polymers in electronic (including optoelectronic and nanoelectronic) devices. Although these ...

Crestatrons could be substituted for TWTs to reduce sizes and weights.
A design study of a crestatron that would operate in the frequency range from 3 to 6 GHz (which overlaps with the C band) has been performed. The basic crestatron concept was developed during the 1950s. The ...
