As Ethernet displaces proprietary field buses, its speed increases are going to facilitate the operation of the digital factory. In its original Top 20 Technologies for 2012 story, EETimes noted that carriers and datacenters have been clamoring for the technology to expand their core backbone networks.
So far it’s still expensive, in part because it still requires a lot of power and board space. But this technology is driving innovation in optical and signaling technologies to lower the costs and space requirements, and those innovations will ripple all across the industry over time.
Meanwhile the industry debates have been fever pitched about what’s the next big step. Engineers feel they are getting close to the limits of physics and what can reasonably be made commercial. Their view is a 400G standard could get hammered out over the next few years, but it will need the next turn of the crank in the underlying serializer/deserializer technology. Beyond that, no one knows what is feasible or when.
Most items have the tags in the packaging. And Walmart for one, mandates supplies use them for inventory control. Problem is that I retain my boxes, at least until the warrenty expires. Of course, placing a box for a 60" TV out for trash pickup lets everyone in your neighborhood know who got a new toy.
Steve - Did your class happen to mention the best way of dealing with those RFID tags? Are these the ones that are in the boxes to prevent shoplifting (so its just a matter of finding and destoying, or are these tags in the new TV's themselves?
I agree Jerry. a lot of the Internet of Things is technology looking for a problem. Some things -- like checking the expiration date on milk -- are better done analog. Like the smart thermostat hat learns your patterns. Is it that hard to turn the heat down when you'll be at work, then turning it back up when you get home?
I agree., I have no interest ijn having RFID tags on everything I own. I took a wireless security class, and one of the things mentioned was some theives were driving around with RFID readers trying to find homes with new televisions. Imagine if they could also hack into your home and shut off all lights before a home invasion? Just because it is possible to do something does not mean we should,
Taking that one step further, Alex, I don't think a lot of consumers see the need for the Internet of Things. I have wireless access in my house, of course, but I see absolutely no need for my refrigerator to be on it. I've seen the ads for those that can keep track of what you have, make shopping lists and download recipes, but I don't need any of that. And after reading all of the monkey-designed washer articles, I SURE don't want anything else for them to get their hands on.
The internet of things does not seem to be taking off in the U.S. the way one would think, given its hype. I think in part this is the expense of adding Internet connectivity to small appliances, but more than that, it's a lack of Internet connectivity on the receiving (receptacle) end in legacy U.S. households. I don't know where the economic impetus will come from to fill in this hole. It's doable; you'd kind of need to deploy PoE (Power over Ethernet). But the numbers just don't work the way they did for, say, cable TV.
Yes, it would have to be on a voluntary basis. Those who want to use the service would be motivated to make sure the tags stay in place. Privacy -- at least on some level -- is a generational concern. Facebook's Mark Zukerberg claims privacy isn’t important to people his age. He backed off that statement when attacked, but nonetheless, he revealed his view and he very well may be right.
That may change as kids get older and find out prospective employers have learned to examine the Facebook sites of candidates.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
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.
