Late with the idea

I was going to a patent search, but too late ... to avoid DUI - Dialing Under the Influence

LG Phone :
ABC News: New Cell Can Tell If You're Drunk:
"You can add one more feature to the list: a sobriety test."

Here's how it works: Users blow into a small spot on the phone, and if they've had too much to drink the phone issues a warning and shows a weaving car hitting traffic cones.

The company also sells plug-in Breathalyzer adapters for some phones. None of the models tell you exactly how much you may be over or under the legal limit, but it can keep you from making other alcohol-related mistakes.

The LP4100 also allows users to set up the phone so on certain nights and after a certain time they do not call certain people in their phone book. Think ex-boyfriend or ex-girlfriend.
