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)...

A software library has been developed that takes a highlevel description of a pattern to be satisfied and applies it to a target. If the two match, it returns success; otherwise, it indicates a failure. The target is semantically a tree that is constructed from elements of terminal and non-terminal...

This software addresses the problem of how to efficiently execute a knowledge base in the presence of missing data. Computationally, this is an exponentially expensive operation that without heuristics generates a search space of 1 + 2n possible scenarios, where n is the number of rules...

A computer program translates Unified Modeling Language (UML) representations of state charts into source code in the C, C++, and Python computing languages. ("State charts" signifies graphical descriptions of states and state transitions of a spacecraft or other complex system.) The UML representations constituting the input...

The Pointing History Engine (PHE) is a computer program that provides mathematical transformations needed to reconstruct, from downlinked telemetry data, the attitude of the Spitzer Space Telescope (formerly known as the Space Infrared Telescope Facility) as a function of time. The PHE also...
