European Union states have approved five new exemptions to the RoHS directive on February 15. The exemptions won’t be official until they are published in the Official Journal of the European Union, but it’s very close.
The new exemptions include the following:
Lead in linear incandescent lamps with silicate coated tubes.
Lead halide as radiant agent in High Intensity Discharge (HID) lamps used for professional reprography applications.
Lead as activator in the fluorescent powder (1 percent lead by weight or less) of discharge lamps when used as sun tanning lamps.
Lead with PbBiSn-Hg and PbinSg-Hg in specific compositions as main amalgam in very compact Energy Savings Lamps (ESL).
Lead oxide in glass used for bonding front and rear substrates of flat fluorescent lamps used for Liquid Crystal Displays (LCD).
These exemptions may only last until technology permits non-toxic substances to perform as well as the leaded versions of these products.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
