Designed for remote- and multiple-axes positioning applications that require programmable peak currents of up to 800 mA, the AMIS-30623 integrates a local-interconnect-network (LIN) interface and sensorless stall-detection. The AMIS-30623 targets mechatronics control solutions that connect remotely to a LIN master and operate in temperatures from -40 to 125C. The sensorless stall detection function allows silent, yet accurate position calibration, as well as semi-closed loop operation when approaching mechanical end stops. Users select motion parameters, such as torque and acceleration-deceleration profiles, in the integrated motion-qualification mode (MQM). MQM helps eliminate noise and vibration at end-stops and improves motion-control accuracy and reliability without using optical encoders, position sensors or software algorithms. Units are available in either SOIC-20 or NQFP-32 packaging.
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.
