A prototype wireless data-acquisition system has been developed as a potential replacement for a wired data-acquisition system heretofore used in testing rocket engines. The traditional use of wires to connect sensors, signal-conditioning circuits, and data acquisition circuitry is...

On-the-Fly Reprocessing (OTFR) is a collection of data-processing routines that work within the context of the Hubble Space Telescope (HST) pipeline data-flow system. The purpose served by OTFR is to generate, on demand, scientifically useful data products from raw HST data stored in an...

A recently developed micro-commanding rotational position control system offers advantages of less mechanical complexity, less susceptibility to mechanical resonances, less power demand, less bulk, less weight, and lower cost, relative to prior rotational position control systems based on...

Multiple-quantum-well (MQW) photodetectors of a proposed type would contain active regions comprising multiple superlattice subregions. These devices would have complex structures: The superlattice of each subregion would be designed for enhanced absorption of photons in a desired wavelength band...

VMETRO (Houston, TX) has released the VirtexTM-5 LX FPGA-based PCI/PCI-X and PMC board-level products. Designed for high-performance general-logic applications, the Virtex-5 is the second generation of Xilinx FPGA to use the ASMBLTM (Advanced Silicon Modular Block) column-based architecture that enables Xilinx to...

The Nucleus®I2C software from Mentor Graphics Corp. (Wilsonville, OR) is now available for developing appli cations needing access to on-board peripherals connect ed via the I2C bus. Demand is increasing for using the low-cost I2C bus to connect peripherals, such as liquid crystal...

CMX Systems (Jacksonville, FL) announced the availability of CMX-RTX™ and CMX-Tiny+™ RTOS for Luminary Micro's Stellaris (Austin, TX) microcontrollers based on the ARM® Cortex-M3 microcontroller core.

Release v8.3 of ObjectAda Real-Time RAVEN environment for PowerPC targets from Aonix® (San Diego, CA) provides RAVEN developers with a choice between the traditional Aonix IDE for development and the AonixADT™ Eclipse IDE. AonixADT incorporates Ada-project awareness, an Ada-language sensitive...

The AIRSAR automated, Web-based data processing and distribution system is an integrated, end-to-end synthetic aperture radar (SAR) processing system. Designed to function under limited resources and rigorous demands, AIRSAR eliminates operational errors and provides for paperless archiving. Also, it provides a...

A software interface has been devised to facilitate optimization of the shapes of valves, elbows, fittings, and other components used to handle fluids under extreme conditions. This software interface translates data files generated by PLOT3D (a NASA grid-based plotting-and- data-display program)...
