Gadget Patents That We Hope Will Turn Into Real Products

They're clever. They're creative. And some of them are just plain bizarre. How come we can't buy products based on them?

Gadget patents can change the world, as everyone from Alexander Graham Bell to Steve Jobs has proved. Some of our favorite gadget-related patents, however, are for technologies and products that haven't changed much of anything--at least not yet.

Here are ten intriguing examples, including ones from both famously inventive companies and lone geniuses. We're not saying that any of them are a catchy ad campaign away from becoming history-making breakthroughs--though one or two might stand a chance. We just like them. And if they ever amount to anything, we'll be first in line to try out the resulting products.

Come Fly With Me

Think of this gizmo as a sort of Segway that goes up (up, up!) and down as well as backward and forward. Technically, it's a "personal flight vehicle" that uses capacitive plates and an ion conditioner to gently lift the user into the air, without the need for rockets or propellers--both of which, the patent notes, are not only noisy but can cause "dismemberment and death."

If the blissed-out expression on the face of the guy using it is any indication, this flying machine not only isn't terrifying, but has a positively calming effect--just the thing to take the airways by storm while we await the inexplicably tardy development of flying cars. But even so, we wouldn't want to be operating a personal flight vehicle that conked out in midair--and a sky full of them is a nightmare guaranteed to make air traffic controllers wake up screaming.

No Glasses Required

We're pretty sure that this exceedingly cool Apple patent hasn't popped up in a Mac, iPod, or iPhone yet: It's for a three-dimensional projection system that doesn't make you don special eyewear. How does it work? A powerful computer projects two images--one for your left eye, and one for your right eye--onto a screen that's actually a "programmable mirror." All the while, a 3D imager keeps track of your head position, helping the computer and mirrored screen optimize the projected image for clarity and realism.

Here's hoping that the technology comes to market someday--and that Apple unveils it with a launch event featuring an insanely lifelike holographic Steve Jobs.

Heckler's Delight

For centuries, audiences have shown their contempt for lackluster entertainment by booing, hissing, or (in Europe) whistling. This Sony patent--eerily reminiscent of cult TV show Mystery Science Theater 3000--harnesses a technology that lets unhappy campers go a lot further. Using a game controller, they can send avatars right into a movie or TV show to fling rotten tomatoes at the actors--or even give them a swift kick.

Admittedly, videos must be specially prepared by their producers to make all this possible. But it's not as though studios and networks are funneling so much money into scripts these days that there's nothing left for CGI. And if you ask us, Rob Schneider should never be allowed to make another film without this technology in place.
