Vibration Isolation in Optical Test Systems

In the world of precision motion control there is a continuous pursuit of higher performance, whether it’s resolution, speed, stability, accuracy or step size. Even if a specified device appears on paper to be capable of achieving excellent results, the design of the mechanics and the platform stability play an integral role in achieving peak performance.

Better, Faster Sonar Development With Multiphysics Simulation

As any dolphin could tell us, sound travels well in water. While water absorbs electromagnetic radiation and light waves over relatively short distances, sound travels widely and even faster in water than in air. That’s why we use sonar (SOund NAvigation Ranging), the acoustic equivalent of radar, to detect and locate underwater objects.

When Human-Machine Interfaces and Control Converge

How Integrated Systems Improve Transportation Today’s human-machine interfaces (HMIs) provide the link between sophisticated technology and the human touch required to effectively operate essential systems and applications. By offering intuitive contact between the operator and the process, users can safely operate trains, build cars, produce manufactured goods, or machine critical industrial parts, for example. Performance advancements continue to drive new embedded designs in these arenas, and HMIs are evolving in step. Integrating HMIs with control systems is proving valuable in many embedded sectors, with the fastmoving, global transportation market leading the charge.

Testing Lenses for Thermal Imagers

Although thermal imagers tend to be judged on the detector technology employed, the detected image must first be formed by an infra-red lens, and the quality and performance of this lens will be an important factor in the overall performance of the imager. For critical applications, it is important to test the lens independently to ensure it meets the required specification before it is fitted to a thermal imaging system.

NASA Awards 2010 Software of the Year

The Kepler mission Science Operations Center Science Pipeline Release 6.0 software system was named 2010 NASA Software of the Year by the NASA Software Advisory Panel. Designed, developed, and operated by the Kepler Science Operations Center (SOC) at NASA’s Ames Research Center in Moffett Field, CA, the SOC software system is used to find Earth-sized planets using photometric data acquired from theKepler spacecraft.

Engineers are Helping Bill Gates Reinvent the Toilet

The Bill and Melinda Gates Foundation has begun a “Reinvent the Toilet” competition and awarded $3 million to researchers at eight universities, challenging them to use recent technology to create models that do not need to be connected to sewers, water, and electricity, and that cost less than pennies per person a day to use. Later prizes will include financing for one or more winning prototypes to be tested and produced commercially.
