By 2020, NASA plans to establish a long-term human presence on the Moon. To make this possible, a reliable stream of consumables such as fuel, food and oxygen, spare parts, and exploration equipment would have to make its way from the Earth to the Moon as predictably as any Earth-based delivery system. To figure out how to do...

BI Technologies Electronic Components Division (Fullerton, CA) introduced the EN line of rotary mechanical encoders. The two-bit gray code incremental encoders are housed in 11, 12, and 16 mm packages, and feature detents and push-on switch options.

Developed at NASA’s Marshall Space Flight Center (Huntsville, AL), a micro-commanding rotational-position-control system offers the advantage of less mechanical complexity, susceptibility to mechanical resonances, power demand, bulk, weight, and lower cost, relative to prior rotational-position-control systems based on...

A self-biased solar cell is available that provides improved conversion efficiency. Loss of carriers at the back surface of the battery is decreased, and open circuit voltage and quantum efficiency near a long wavelength are increased. View this technology here.

Lightweight, High-Performance Propeller/Rotor/Wind Turbine Blade The turbine blade features a much lighter, more efficient, less expensive, and entirely new structural design. Other advantages offered bythis technology include increased performance, lower noise, decreased maintenance time and expense, and optimized...

Methods are available for the determination of building stability in the event of an earthquake. These methods involve the development of existing shaking table technology to allow more efficient characterization of structural properties. View this technology here. An approach accompanied by a comprehensive algorithm and...

A researcher at Technische Universiteit Eindhoven (Eindhoven, the Netherlands) has developed a software patch that can increase a car's fuel efficiency to a total fuel savings of 2.6%, without having to replace any of the parts of the car. Uploading a software patch to the car's computer and adding one small cable suffices.

IM Mobile -- World's fastest, full-functionality, single-user Data Base Management System (DBMS), with unique built-in synchronization. It is about four times faster than Microsoft SQL Server 2005 Mobile on a PDA, making the user experience completely different. Click here.

Using optical fibers, researchers at the Georgia Institute of Technology have found a way to create a sensor that detects the direction from which a sound is coming under water. The new sensor could allow the U.S. Navy to develop compact arrays to detect quiet underwater targets, while also providing unambiguous directional...

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...

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...
