USA TOLERANCE RINGS and Ididit, a manufacturer of custom steering columns for hot rod, race, show and specialty vehicles based in Tecumseh, MI, collaborated to develop a collapse ring for steering columns. The ring, designed to keep a driver safe in a front-end collision, is available chrome-plated or powder-coated and keeps the existing low-cost 16-gauge DOM tubing. A flanged tolerance ring with an advance wave configuration is fitted between the tubes and retained by the outer tube while the inner tube slips axially inside the ring. The target axial collapse force of 550 lb ± 100 lb is achieved while maintaining ease of assembly within components having a stack up tolerance of .020 inch.

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.
