It could be that the ZigBee wireless networking spec is just the ticket for those who want to use technology to simplify every aspect of their lives. The 150-plus members of the ZigBee Alliance tout all sorts of applications for IEEE 802.15.4, which was finalized last year. There's been an onslaught of chip unveilings since then. Some predict those chips will see their first usage in industrial applications, while many predict that consumer products from lamps to refrigerators will be the first big market.
Alliance Chairman Bob Heile is in the latter group, feeling that consumer volumes will help give industrial users the assurance that the technology is reliable. Among his many predictions for new products, he thinks the trends toward exotic footwear and health awareness will prompt the creation of ZigBee shoes that send information to an exercise monitor. They will factor in distance and the terrain being traversed to give serious runners instant input on heart rates and calorie counts. ZigBee could even provide an incentive for completing the workout. "The shoe could send a message to the refrigerator when you return home, locking the door if you haven't completed your workout," Heile jokes. www.zigbee.org
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.
