Gadget Freak Case 102: Rob's Watching His Truck's Diet

NO RATINGS

Robert Kwiatkowski designs and deploys data logging systems for Condition Based Maintenance on aircraft carriers. With gasoline prices soaring, he wanted to improve the fuel efficiency of his thirsty truck. As a first step, he's doing some data logging via the OBDII port using this simple interface, a laptop computer and Windmill, a data acquisition application. With post-processing via MS Excel, he can monitor mpg in real time and compare fuels, additives and driving patterns to optimize his mp$ (miles/dollar).

Embedded Angles for Medical Products
February 21, 2pm EST Tuesday
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.
