Magnets let this cable carrier float within its track
You may be tempted to lump all cable carriers together because their differences tend to be subtle ones related to the geometry of their links and their use of wear-resistant materials. At the fair, though, Igus GmbH demonstrated a carrier with a high-tech twist that was hard to miss. The company debuted a "magnetic energy chain" that floats within its own track.
To turn an ordinary energy chain into a maglev system, Igus installed magnetic modules on both sides of a fixed track and embedded pieces of iron in the plastic links of the chain itself. The result: a reduced-contact cable carrier that moves quickly with lower forces, less wear and reduced noise. The lower half can optionally be fitted with magnetic modules too, opening up the possibility of a chain with still greater wear resistance and whose top and bottom halves can move independently. According to Frank Blase, the company's chief executive officer, the magnetic system can move at speeds up to 15 m/sec, carrying loads of up to 4 kg/m of chain. A chain with 40m of travel, the maximum for this system, can accelerate as quickly as 90 m/s2, Blase adds. "That's impossible with any other carrier system today."
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
