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
Design collaboration now includes the entire value chain. From suppliers to customers, purchasing to outside experts, the collaborative design team includes internal and external groups. The design process now stretches across the globe in multiple software formats.
A new high-pressure injection-molding technology produces near-net shape parts with 2-inch-thick walls from high-performance materials like PEEK, PAI, and carbon-filled polymers. Parts show no voids, sinks, or porosity, have more consistent mechanical properties, and are stronger.
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.
