Ryan Pooh-Poohed Those Low-Carb Diets

NO RATINGS

To keep his roommates from pilfering his beer reserves, Ryan resolved to build a Fort Knox-like protection device. The BeerBot waits for a correct activation code and then pours (drizzles out, actually) beer until a sensor detects the cup is filled. If the thirsty perpetrator enters the wrong code, a speaker sounds an alarm and a counter is incremented—a combo that most assuredly will prevent all but the most foolhardy from attempting another break-in. Ryan now sleeps peacefully knowing his beer is safe and sound.

Check out all the details!

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.
