Infrared Smoke Alarm

Inventor: First Alert

These days every home has at least one smoke alarm. But how many of us have yanked the batteries out in frustration because that annoying shriek goes off every time we broil a steak or toast a bagel? The Smart Alarm offers a cure so simple we should have thought of it: you turn the alarm on and off by remote control. Just point any remote at the alarm and hold down any button for five seconds.
