Figure 2. The encapsulant surrounding these intrinsically safe fuses keeps them sealed, limiting the energy and temperature generated during fuse operation. It also prevents dust from entering the fuse body, which makes it ideal for use in hazardous environments.
I agree with the point about fledgling engineering teams at startup companies. Exposure to other more experienced, cross-functional members on standards committees can rapidly develop new engineers and also help reduce the 'hard and expensive' lessons of going back to the design drawing board when simple mistakes were not avoided.
Of course it makes sense for the LittleFuse company to participate in standards development. Not only do they have quite a bit of experience in the field, but since they are mainly a producer of circuit protection devices, it is certainly to their advantage to help prevent any really dumb requirements, typically driven by emotions rather than any data, which some may choose to present. It is seldom useful to have the emotionally driven ideas from the technically ignorant entering into engineering decisions. We have a few examples of that mode already.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
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.
