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
More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
