Yes, I remember the difficulties with component tracking and part numbers. For some reason REACH didn't see to cause the same consternation. At least not that I noticed. I guess it's becasue REACH was more of a reporting function.
Actually, among the high-end embedded board-level products we covered, RoHS seemed to affect most the manufacturers that served both mil and commercial customers, since they often ended up running two separate lines for two different versions of the "same" product. Mil-only board manufacturers were not affected much until later. One thing that did affect them both was the nightmare of components tracking and part numbers changing.
Since there were only two of us, myself and the editor-in-chief, I did a little of everything. Mostly we did not address distribution, but design and development technologies for HW and SW, comms, and a lot of board-level products and technologies. I wrote several features on RoHS, too.
As I learned working for COTS Journal, COTS doesn't just mean actual end-system computers and apps software. It can also refer more broadly to both software and hardware design and development platforms, specifically for creating end-system hardware and software used in the field. Ruggedization is taken for granted for military field use; that feature doesn't determine whether a machine is COTS. A COTS-based machine may also be further tweaked--and usually is--for specific apps. The big difference is that the military is no longer spending zillions of dollars on proprietary, entirely customized systems.
What I've heard is that the COTS stuff is used for office and support functions. When it comes to electronics out in the field, the electronics are ruggedized (and leaded) so they can withstand a difficult environment over many years.
The COTS systems, platforms, networking technologies, and software are, as the term says, commercial off-the-shelf hardware and software, meaning stuff that's originally designed and built for the rest of us. Basically, that means the military is using Windows-based laptops and other standard commercial hardware and software, as well as standard networking protocols, which is actually kind of scary. This is instead of spending zillions of dollars on designing their own stuff, like in the "good old days." Even the NSA buys a lot of standard signal-processing equipment.
I wasn't aware of that, Ann. I thought they were just cheap commodity parts. But it makes sense that systems and platforms could become commodity items that could be used in a variety of products.
Interestingly, many of the older "antiques"--more like family heirlooms--in my house are made of bio-based materials, such as wood and paper (which also used to be considered sustainable materials until we nearly used them up), or ceramics and brick, which are sustainable. Even metals were sustainable, and still are. Most of these materials are commonly found in the rubbish heaps of our ancestors, and give archaeologists a lot to study. Much of the problem with materials becoming non-sustainable has occurred in more recent times because of overuse (due in part to enormous population growth), as well as because of newer materials with complex processes and polluting wastes.
Researchers at MIT and Sandia National Labs have observed a reaction in lithium-air batteries that could help improve the design of these cells for electric vehicles and other applications.
Healthcare might seem to be an unlikely target application for the Internet of Things technology, but recent developments show small ways that big-data is going to make an impact on patient care moving into the future.
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
