Protecting Signal Integrity in Industrial Environments

Data communications in industrial environments can present special problems. Lines must be run over long distances, often ranging from thousands of feet to several miles, indoors and outdoors, from the field to the control room, and from building to building. These data communication systems must be able to function in the presence of electrical transients, and noise, ground loops, and surges from nearby lightning strikes.

Goddard Space Flight Center

This feature profiles NASA’s ten field centers located across the country. Each month, we’ll highlight a NASA center’s unique facilities, capabilities, and areas of research, as well as specific missions and projects underway at each center. If you are interested in partnering with a particular center, or in licensing specific technology, check out the More Information section at the end of each profile for contact information.Goddard Space Flight Center’s (GSFC) primary role is to develop science and technology to support unmanned missions to study the Earth, Sun, solar system, and universe. GSFC is responsible for several of NASA’s highest-profile accomplishments, including the Hubble Space Telescope (HST) and the upcoming James Webb Space Telescope (JWST). GSFC has one of the world’s largest teams of engineers and scientists dedicated to advancing our knowledge of Earth and space. The Center is located in Greenbelt, MD, 15 miles from Washington DC and 30 miles from Baltimore, MD.

Understanding Infrared Detector & Emitter Technology

Generally speaking, sensor manufacturers are driven to improve performance (i.e. offering greater sensitivity, smaller packages, more features) and lower costs. The prioritization of these sometimes conflicting demands varies with each target sensor application. For detector manufacturers, this translates into an assortment of requirements including high sensitivity, expanded range of operation, more integrated products, and low cost solutions. Final detector selection will depend on which attributes are most important for the target application.

Don’t Miss Out on Creating the Future

Time is running out to enter the 2011 "Create the Future" Design Contest. Entries for the ninth annual contest are due by June 30th. Click here to submit your design idea.Sponsored by COMSOL, Creo - a PTC product, and Tech Briefs Media Group, the contest recognizes outstanding innovations in product design, awarding a Grand Prize of $20,000 USD. New this year is an Electronics Design category sponsored by Digi-Key Corp. Other categories are Consumer Products, Machinery & Equipment, Medical, Safety and Security, Sustainable Technologies, and Transportation. Entries can be submitted by individuals and/or teams in up to seven categories. The top entry in each category will receive a workstation computer from Hewlett-Packard. The top ten most popular entries, as voted on by site registrants, will get a 3D mouse from 3Dconnexion. All qualified entrants will be included in a drawing for NASA Tech Briefs T-shirts, and the winning entries will be featured in a special supplement to NASA Tech Briefs magazine. If you haven’t submitted your design, you have until June 30th to visit www.createthefuture2011.com and enter your great idea.

Steer-by-Wire Systems with Integrated Torque Feedback Improve Steering Performance and Reduce Cost

Hydraulic steering systems have long dominated the industrial utility vehicle market because of their familiarity both to vehicle designers and operators. More recently, a trend has been seen towards the use of electronic steer-by-wire systems that provide greater design flexibility by enabling software to customize the connection between the steering wheel and steering mechanism. Several suppliers offer integrated steer-by-wire systems targeting the industrial utility vehicle market. A key differentiating factor is the method used to provide torque feedback to give the operator a heightened sense of vehicle control. The latest generation of integrated steer-by-wire systems consumes less power, is less expensive, and offers the ability to be programmed to provide a wide range of value-added features.
