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.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
Ear-based heart-rate monitoring gained momentum recently, as sensor maker Valencell Inc. announced it has licensed its biometric earpiece technology to Samsung Electronics Co. Ltd for use in so-called “hearable devices.”
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.
