The High-precision Ball Rail System provides greatly reduced rolling, pitching and yawing deviations in linear guideways due to ball recirculation. The extremely smooth motion with virtually no deviation in the X, Y or Z direction, makes the system ideal for measuring and scanning devices requiring ultra-precise movement such as those found in semiconductor manufacturing, as well as high-end machining. Improvements to the bearing raceway geometry minimize ball pulsations and reduce the influence of guideway bolts on the running smoothness of the runner block. With standard availability in XP, SP, UP carriages (preloaded sizes 15 to 45), with or without ball chain technology, the high-precision system is also offered in single piece rail lengths up to six meters.

Inforbix is leveraging its CAD and product data access technology to power up a free iPad app that lets mobile users search and access engineering data.
Unlike his friends in engineering programs, blogger Jon Titus had little need for calculus except in a few of his college physical-chemistry labs and classes.
In the wake of the Chevy Volt fire investigations, sales are down, and General Motors' (GM) CEO Dan Akerson is blaming the downturn on a spate of bad publicity.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
