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.

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.

Fiber Delivery of Lasers in Bioinstrumentation

In many laser-based types of bioinstrumentation, including flow cytometers, confocal microscopes, and array readers for proteomics, laser output is delivered to the system’s final optics regime via fiber coupling. Over the past few years, this fiber delivery has evolved from simple remote delivery to finally encompass plug-and-play use of multiple lasers with sub-micron beam positioning accuracy. This capability is supporting a new generation of instruments that combine state-of-the-art performance with ease of use.
