Switch to Electronic License Plates Could Improve SC Highway Safety

 

 

 

 

” South Carolina is considering a proposal, still in its early stages, to switch from metal license plates to new electronic license plates, or e-tags, as a way to improve highway safety.

“It’s the first of its kind,” says David Findlay, co-founder of Compliance Innovations, the South Carolina company that created the e-tags.  “It’s not an LCD or an LED. What it’s made of is electronic paper. It’s a new technology that allows you to hold the image with no power whatsoever for over 10 years. The only time it needs power is when you’re changing the status or the image on the plate.”

That power comes from the vibrations of your car, and from a transparent film over the tag that collects solar power.

The reason e-tags should improve highway safety is because the tags would be electronically linked to the DMV, so if a driver’s license has been suspended or his insurance has lapsed, the DMV would send a signal to the license plate. The word “SUSPENDED” or “UNINSURED” would appear on the license plate.

If your car is stolen, the DMV could make the tag read “STOLEN”. The state could also use the tags during Amber Alerts or other emergencies.”

Glowing Ice Cubes Warn You When You Drink Too Much

 

Smart Cubes

 

 

” In November, MIT grad student Dhairya Dand blacked out at a party and woke up in the hospital. Some people might use that as a wake-up call to lay off the tequila shots for a few weekends, but Dand, an engineer and former educational toy designer, did one better. Three weeks later, he had created a set of glowing ice cubes called Cheers that let you know when you’re going too hard.

A circuit enmeshed in an edible jelly mold monitors the number of sips taken, using an accelerometer that tracks the drink’s motion, and calculates how drunk you are based on a timer. Using three cubes with different LED lights, your drink changes color from green to orange to red, letting you know when you should take it easy. “
