STANFORD, Calif. -- Business students, startups, and campus researchers showed off their latest innovations yesterday at the Cool Product Expo at Stanford University. The R&D project topics ran the gamut, from transportation to medical devices. But most shared one thing in common: coolness.

Take, for example, Scent Sciences, which is adding another sense to your digital entertainment: smell.

Soon, your games, movies, Internet and TV might really start to stink. It's creators say that eventually, these little smell generators will be in cell phones, too. Instead of a custom ringtone, you might assign a smell to someone's call.

And in the not too distant future, the technology will be made into wireless clips for movie theaters. Go to the movies, and receive your 3D glasses along with your scent clip that will dispense the smells of the film.

Click on for more of the big ideas coming out of the Stanford Cool Product Expo.

The heads-up QnQ touch-screen device for DJs gives the audience a better look at how the audio masters work.

The gear gives DJs a 46-inch multitouch interface allowing for better customized access to tools. The transparent screen gives those on the dance floor an up-close view of the action.

Aftershokz off-ear headphones use bone conduction technology to deliver your tunes right into your skull. Besides just being very cool technology, the sport headphones are super safe due to the fact they don't shut you out from the world. While listening to music, you can still hear the world around you, like cars and people talking.

Automated external defibrillators, or AEDs, are portable defibrillators, an increasingly important tool for delivering immediate medical attention in public places.

The Beacon is a connected AED that is breaking down the primary barrier to wider availability of these life saving units: maintenance.

Current laws require these systems to be checked regularly to ensure they are active and working properly, requiring a lot of man hours. The wireless Beacon system enables automatic completion of these mandatory checks, reducing labor costs and improving accuracy and accountability.

Add GPS tracking and integrated fire, EMS and 911 dispatch, and these tiny units are compact emergency response units just about anyone can use.

Fuisz Media wants to make product placement in video better. Its process creates hyperlinked objects in video, which allows a viewer to click on products, such as shirts or necklaces, and get more information and a point of purchase.

The algorithm even identifies actors in film and links out to their profiles.

Kix Friction balls are training balls that are covered in tiny fins, making the ball intentionally sluggish. On pavement, the fins make the ball stop fast, not continue rolling, as if it is rolling in thick grass. Through the air, increased resistance cuts in flying distance in half.
