Remember that scene in 'The Dark Knight' where (spoiler alert!) Batman uses the city's cell-phones to look through walls and find the bad guys? Totally awesome, right!? A group of scientists at KDDI apparently thought so too, creating a prototype they say could do something similar. Using geomagnetic sensors, accelerometers, and GPS, the device is able to determine its position and render its surroundings on the screen in OpenGL, including areas that are currently out of sight. We're guessing you must have already scanned those areas with the phone and that it can't actually see through walls, but we'd be happy to be proven wrong -- whenever they actually have something to show us. Like the group's funky concept phones we brought to you earlier, this one doesn't actually work. Yet.

Toshiba continues to tease us with its prototype liquid fuel cell-powered gadgets: last year it was a Gigabeat media player, and at this year's CEATEC you can check out a direct methanol fuel cell (DMFC) that's been crammed inside a cell phone, lending it a robust six hours of talk time (compared to the paltry three or four hours of a traditional battery). Toshiba won't reveal the capacity of the DMFC, but they have said that a 50ml cartridge is good for about 15 refills. No release date yet, but the phone "might" be available "as early as next year." In the meantime, enjoy this picture of a woman holding a flip phone with "DMFC" clearly visible on the display.

We got all down and dirty with DoCoMo and Fujitsu's prototype "Separated phone" today at CEATEC, and we can confirm that the device does, in fact do what they say it does. As reported earlier, the device uses Bluetooth to communicate between the phone's two magnetized halves, enabling configurations in everything from standard clamshell to gaming landscape formats. Perhaps the most compelling configuration is one that allows the phone to be held to the ear while one accesses data on the another half, complete with neck cramps. The touchscreen, Symbian S60-based UI was easy enough to use (albeit in Japanese) and features a hearty media playback element, but we were unable to squeeze any commitment to a launch date, price, or probability of seeing the unit on the market. That all said, the demo units were very much operational as you can see for yourself in the video after the break.

When the coup de grace of your CEATEC showing is a concept phone designed to look like a frickin' satellite, you know you've got some winners on your hands. KDDI's known for trotting out some really cool concepts in the past, and its latest batch is no exception -- check 'em out over on Engadget.

DoCoMo and Fujitsu are showing off some interesting phone tech in Japan at this year's CEATEC, particularly a concept device which can be split into two pieces. The gadget features a separate screen and keyboard segment, and the pieces can be configured in a standard flip-phone-like arrangement, or snapped together to form an X1 or Touch Pro-esque landscape QWERTY variation. The two halves are held together by magnets and communicate via Bluetooth. Of course, right now this is very much in the concept phase, and honestly -- aren't we trying to minimize the amount of electronic components we're carting around? Still, it's a fairly slick design, and certainly a new way of thinking about phones. Take another look after the break, and hit the read link for a slew of pics.

Sure, you can grab your Nike+iPod Sport Kit and try to work off a few calories, but will that contraption become your drill sergeant when you decide to call it quits five minutes in? For those that need constant motivation, NTT DoCoMo has you covered -- if you understand Japanese, that is. Reportedly, the firm was showing off a D903i equipped with software that can not only "check for bad breath," but it can also check your body fat and keep tabs on your heart rate. Granted, we can't confirm that the translations shown above are entirely accurate, but this type of honesty would never fly in the US, anyway.

Remember that Super 3G network you tried to forget about after realizing it'd likely never leave Japan? Yeah, well NTT DoCoMo and Fujitsu were busy showcasing a prototype base station that supports the specification at CEATEC. Reportedly, the device "marked a download rate as high as 900Mbps" when utilizing MIMO. Sadly, there was no mention of this technology (nor the base station) going commercial anytime soon, but we'll take every demonstration we can get in the meanwhile.

An e-ink primary display on a cellphone? Eh, that's so 2006. On display at Japan's CEATEC show this week is a prototype clamshell that flips the concept on its head, moving the e-ink down below. The benefits are pretty obvious -- different keypad configurations can be shown in different phone modes, a tactic that's been explored before -- but unlike phones that use OLED or LCD displays, e-ink only requires power when it's being changed, so you get the combined benefit of configurable keys while consuming virtually no additional energy over a standard layout. Combine the concept with physical ridges between keys and we figure this could be a pretty killer setup since you wouldn't be losing tactile feedback, either. We see a good fifteen or twenty concept phones for every device that actually sees production, but since some folks bothered to throw together a physical prototype here, we're cautiously optimistic this thing might see the light of day.
