Nuclear detonations caught the world's attention this summer when India and Pakistan tested their potential strength. To monitor the Comprehensive Nuclear-Test-Ban-Treaty, scientists at the Department of Energy's Pacific Northwest National Laboratory (Richland, WA) developed two devices for detect nuclear detonations. The Automated Radioxenon Sampler/Analyzer (ARSA) and the Radionuclide Aerosol Sampler/Analyzer (RASA) inspect the atmosphere for traces of radioactive material. Once activated, the systems will be located around the globe as an international monitoring system. ARSA analyzes air samples for radioactive xenon or radioxenon that seeps from underground nuclear explosions. The system collects air samples and processes them to trap the radioactive xenon on cold charcoal. RASA detects fission products from atmospheric explosions. It daily filters a huge volume of air to check for evidence of fission products from a nuclear explosion that attach to dust particles. Information collected by the ARSA, RASA, and other monitoring systems at the global stations will be passed on to an international data center. Call (202) 586-5806.
There is currently much discussion around the term "platform," which may be preceded by the adjectives "mobile," "wearable," "medical," "healthcare," etc. However, regardless of the platform being discussed, they usually have one key aspect in common: They tend to be wireless. So, why is this one aspect so fairly universal? The answer is convenience.
Everyone has a MEMS story. For most of us it’s probably the airbag that saved our lives or the life of a loved one. Perhaps it’s the tire pressure sensor that alerted us about deflation before we were stranded alone on a dark muddy road.
Bioimimicry is not merely a helpful design tool -- it also encourages designers to think not only about how to solve design problems by imitating nature, but how to make the products, materials, and systems they design more ecologically sound and nature-friendly.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
