Bob's Apple-Stealing Varmint Was a Nearsighted Nuisance

NO RATINGS

Tired of marauding wildlife munching on his mums, Bob Forman designed a simple motion detector device that automatically triggers a sprinkler system when unwelcome visitors stray over his property line. Not only does the dog across the street get an occasional dousing, but also Forman's lawn and garden stay well-watered. The device works effectively on small children and door-to-door salesmen too!

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.
