Smarter headlights could guide you out of a rainstorm, but intelligent tail lights could enable communication between vehicles. At least, that's the idea behind a collaborative Connected Vehicle Safety project between Intel and National Taiwan University. Its purpose is so that you'll be able to know just what the vehicles around you are up to -- whether they're speeding or braking or making a left -- by receiving data from their tail lights. Your vehicle could then stop or accelerate automatically without you needing to intervene, or you could choose to react manually if desired. We saw a demonstration of the concept at a Research @ Intel event in San Francisco with a couple of scooters, so head on past the break to learn how it all works, with video to boot.
Both scooters in the demo are hooked up to a laptop running GNU radio and Universal Software Radio Peripheral (USRP), but we were told that in real-world applications, a palm-sized microcontroller would be sufficient. The front scooter has a VLC FrontEnd board that talks to the tail light, while the rear scooter has a photo diode with a 120-degree viewing angle mounted underneath its handlebars. The diode would be able to use the receiving signal strength from vehicles around it to determine which is closest. Modulation of the tail light flashing frequency prevents interference and allows multiple vehicles to be tracked simultaneously.
In the demo, we saw that when the front scooter hit the brakes, the smartphone mounted on the rear scooter showed a red square. Similarly, when the front scooter made a left turn signal, a left arrow appeared on the display. Divya Kolar, a technology evangelist at Intel, told us that when all of this information is collated together, it'll be able to transmit the traffic patterns to the cloud so that others not in the same vicinity can learn from it and change their routes appropriately. Of course, this is still all in the research stage, so we likely won't see this in our vehicles any time soon. Check out the video below if you want glimpse of our connected vehicle future.

ASUS has just unveiled a new tablet, and it marks the return of the MeMo Pad series. This one is a 10-inch, 9.5mm-thick slab, housing both a dual-core, 1.6GHz Intel processor and Android 4.2 Jelly Bean -- another Clover Trail+ powered tablet from the Taiwanese company. Perhaps just as notable is the inclusion of a 1,920 x 1,200 backlit 10-inch screen -- one that's capable of 1080p video playback and one that performed just as admirably as recent ASUS tablets. We're promised 10 hours of use from the 25Wh battery, with all the requisite Bluetooth (3.0), WiFi (802.11 a/b/g/n) and GPS connectivity. There are also dual speakers but we're waiting to confirm if this means stereo sound. It'll arrive in two configurations: 16GB and 32GB, in either dark blue and white. The whole package weighs in at just 580g and we just got to handle it for ourselves -- check out our impressions and hands-on video right after the break. We'll be updating the post with pricing and availability when we hear more. ASUS MeMo Pad FHD 10 hands-on
