Keeping Hackers Out of Industrial Control Systems
It seems that there’s always a hacking story in the news, the most recent being a hack of Twitter accounts which you’ve likely read about. Hackers had managed to con a couple of Twitter employees into giving them access to their credentials. They used these credentials to make their way past security and sending out […]

Keep your distance! Technology for maintaining social distancing.
If you’ve been in a grocery, pharmacy, or big box store recently – or lined up outside a Starbucks – you’ve seen the duct-taped X’s telling you where to stand to keep your social distance from the person in front of you. And if you’ve been taking walks – or just walking down the aisle […]

Oura rings enlisted in the fight against COVID
Remember mood rings? They were a 70’s fad that recycles every once in a while. The rings contained liquid crystal, which changes colors when the temperature of your finger changed. Red means you’re excited. Gray, nervous. Blue, calm. The science was a bit sketchy, but there was something to it. Anxiety sends blood towards your […]

I’m always bookmarking articles of interest, and in going through my backlog, I just came across one on underwater energy harvesting that appeared in EETimes this past February. (And speaking of February, doesn’t that seem a million years ago?) In the article, Bill Schweber describes a new approach that some MIT researchers are using. The […]

Mind over matter. In this case, a prosthetic hand.
Mind-controlled prosthetics for amputees have been around for years. And they’re amazing. But the functionality they provide is limited. They can be awkward to use and don’t provide fine motor control. And their use was generally confined to those who hadn’t just lost a limb, but who were also paralyzed. That’s because it required a […]

Running on Technology
This past Monday should have seen the running of the Boston Marathon. I’m not a marathoner, but it’s hard not to pay just a bit of attention to Boston, the longest running (since 1897) marathon in the world. The event, like so many others, has been postponed due to the coronavirus pandemic, and will be […]

From the MIT Technology Review: 10 Breakthrough Technologies for 2020 (Part Two)
In my last post, I described the first five breakthrough technologies listed in the March/April edition of The MIT Technology Review. In this post, I’m doing the remainder of the Top Ten. (In parentheses, after each section, I’ve noted the writer for that article.) Satellite Mega-Constellations: This article starts with a fairly startling statement: “More […]

Tech takes on the coronavirus
It’s probably safe to say that one of the things that’s first and foremost on all our minds these days is the coronavirus pandemic. And it’s not just on our minds, but in our everyday lives that are so impacted. We may be working from home – as many of our Critical Link employees are […]
