New Manufacturing Technique Could Lead to Brighter, Smarter, More Efficient LEDs

Ming Ma, a doctoral student in the Department of Materials Science and Engineering at Rensselaer Polytechnic Institute, has developed a new method to manufacture lightemitting diodes (LEDs) that are brighter, more energy efficient, and have superior technical properties than those on the market today. His innovation holds the promise of hastening the widespread adoption of LEDs and reducing the overall cost, energy consumption, and environmental impact of illuminating our homes and businesses.

Researchers Demonstrate New Way to Control Light in Semiconductor Nanocrystals

As demand for computing and communication capacity surges, the global communication infrastructure struggles to keep pace. The problem is that light signals transmitted through fiber-optic lines must still be processed electronically, creating a bottleneck in telecommunications networks.

Designing Rugged, Standards-Based Embedded Solutions

It can be argued that small form factor design trends are paradoxical. As form factor size decreases, functionality requirements increase; as processing power requirements heighten, lower power consumption and thermal output is expected. Add to that the requirement for ruggedness to accommodate for the shock, vibration, humidity, and temperature extremes and variance inherent in mobile and outdoor applications, and designers are faced with a very complex soup.

Tips for Selecting or Designing a Membrane Switch

Membrane switches are known for standing up to tough environmental conditions. Flexible and durable, the membrane switch can be customized with embossing, backlighting, sealing, and electrostatic discharge (ESD) shielding. Membrane switches can be made with either tactile or non-tactile feedback and they can be integrated with LEDs and other components. To get the switch that works for your application, follow these simple guidelines.

Digital Picture Technology Connects Sports Teams with Fans

NASA-developed digital photo technology lets baseball fans enjoy highly detailed panoramic pictures.

NASA’s twin Mars rovers, Spirit and Opportunity, remain one of the Agency’s greatest achievements in exploration. On Earth, these robots are best known for their stunning pictures of the Martian landscape. Although the rovers each had a mere 1-megapixel camera, the pictures they have become famous for measure up to 96 megapixels in size. This was made possible by a NASA-built automated tripod that, with the help of photo processing software, seamlessly integrates a series of smaller shots into one large image.

Flexible’ Machine Vision: Sensors, Lenses, and Software

Machine vision has become indispensable in today’s highly automated manufacturing environments, which rely on accurate in spec tion to ensure high product quality and high process efficiency. Applications for the technology span industry, and include everything from validation of printed barcodes and text on consumer product labeling, to assembly verification of printed circuit boards, to dimensional measurement of automotive parts. The demand for vision inspection only continues to grow with increasing throughput requirements and stringent quality standards that necessitate full inspection and render manual product inspection unfeasible.

Pixel-Scale Coated Sensors Bring Multispectral Imaging to New Users

The pixel-scale patterning of optical filters directly onto sensors has the potential to drastically simplify and scale down the cost of real-time multispectral imaging. Without moving parts, a more robust and compact system can be deployed into harsher environments than have been previously accessible for multispectral imagers.

A New American Space Age

NASA and industry are working together to ensure safe, reliable, and affordable space transportation launching from U.S. soil by mid-decade.

NASA and its industry partners are developing a U.S. commercial crew space transportation capability with the goal of achieving safe, reliable, and cost-effective access to and from low-Earth orbit and the International Space Station. Through a program begun in 2006, NASA is investing financial and technical resources to stimulate efforts within the private sector to develop these capabilities.

Linear Guide Systems Streamline Aircraft Seat Assembly and Operation

Linear guide rails are an important component within aircraft interiors. Following are some of the places where they are used:

• For seat adjustments — forward and back seat movements, footrests, sliding armrests, and tables.
• Rails enable 180° positioning for super first class seats that flatten for sleeping.
• Sliding privacy screens between passengers.
• Kitchen slide-outs, such as garbage compactors.
• Sliding lavatory doors.
