Sony, Sumitomo push laser projectors forward with a new, more powerful green laser diode
As cool as lasers are, so far there are precious few commercially available display devices available that use them. That may change with this new green semiconductor laser diode announced by Sony and Sumitomo, capable of the brightness necessary to replace the more expensive light sources used to fill in the middle of the RGB setup. According to the two companies, it's the world's first one capable of over 100mW power at 530nm, which they think will make it a fit for both advanced projectors and compact light projectors. Check after the break for more details on how the technology came to be -- drawing heavily on Sumitomo's production techniques and Sony's GaN laser technology developed with Blu-ray -- we'll let you know when there's a LaserVue or REDray setup priced for general consumption.
SEI creates new porous Aluminum-Celmet, makes rechargeable batteries last longer
Quick: What costs hundreds of dollars and dies after four hours? If your answer included anything portable and tech-based -- you guessed right. In fact, most of our magical and exciting gadgetry has less-than-stellar means of holding a charge, but a recent breakthrough by Sumitomo Electric Industries could change all that. Employing the same process used to create Celmet (a NiMH component), researchers at the R&D company managed to coax aluminum into being a bit more receptive. The resulting Aluminum-Celmet has a whopping 98 percent porosity rate, leaving the Li-ion gate wide-open for a flood of electrical juice. And unlike its nickel-based brother, this piece de porous non-resistance has a steep corrosive threshold that could soon help power a line of high-capacity, small form rechargeable batteries. Production is already underway at Osaka Works, with SEI hoping to speed adoption of these franken-batts into our mass consuming mitts. Technical-jargony PR release after the break.
Elevator operating robot janitor goes on sale in Japan
In one year alone we've seen robots shaking things up in such far-flung fields as fashion and interpretive dance. That said, our concerns are generally more prosaic -- that's why we're most excited by the industrial strength autonomous sweepers developed by the likes of Fuji Heavy Industries, Sumitomo, and Subaru. Like last year's model, their latest sweeps the floor, picks up the trash, is able to operate modded elevators, and comes equipped with laser sensors for avoiding obstacles and may even be outfitted with a camera. In addition, this new guy has slimmed down to about half the size (better for slipping into tight corners) and sports a twenty-four volt battery that gets about 2.5 hours per charge. The best news, however, is that it's finally for sale! It should hit the streets of Japan by the end of next year for a price somewhere in the $35,000 to $46,000 range. We'll take two.

Panasonic and Sumitomo see eye to eye in this OLED game, big screens due in 2010
Ready with the proper retort to all those rumors, false starts and misquotations, the Nikkei is reporting that Panasonic and Sumitomo are zeroed in and have the tunnel vision to deliver the 40-inch plus OLED HDTVs we've been waiting for within fiscal 2010. Once organic electroluminescent product is flooding the streets, the plan is apparently to cut the power requirements of the bright, slim displays to less than a third of current LCDs by 2015, right around the time Samsung thinks this tech will be ready for the mainstream, anyone else care to make a prediction?

Sumitomo debuts superconductor powered electric car
Okay, the science nerds in the audience didn't exactly let us know that we've entered the age of commercial superconductors, but apparently Sumitomo Electric has built a Toyota Crown Comfort that's powered by a superconducting engine. Cooled by liquid nitrogen to -200° C, apparently all this madness nets you an extra 10% gain in distance over regular battery-powered motors. In other words: totally, completely worth the near comical impracticality.[Via Uber Review]
Researchers tout spreadable, self-powered OLEDs
It looks like we could one day be buying our OLED displays by the jar or the bucket-full, at least if some researchers from Sumitomo Chemical and Mitsubishi Chemical have their way. They're now working on what they describe as "spreadable" OLEDs, which could either be spread or "painted" on virtually any surface, leaving an OLED screen that would be just 100nm thick. As if that wasn't enough, the spreadable concoction would also double as a solar panel that'd keep the OLEDs powered, something that's apparently possible due to the "similar, but opposite, principles" that OLEDs and solar cells work on. What's more, while the two companies are apparently still in the early stages of research, they say they're aiming to have usable prototypes ready within the next two years. [Via OLED Info]
Sumitomo may not actually produce OLED TVs in 2009
Whoops! Looks like Sumitomo President Hiromasa Yonekura was "misquoted" just a few days back, and there may actually not be any large OLED TVs churned out by the outfit in 2009. According to a new report, Sumitomo is currently "working with partners," thus the "timing of any product launch is not just its call." No worries -- we're fairly certain someone else will step up to the plate in your absence, right guys? [Via OLED-Info]
$170,000 Japanese-style Roomba takes home the gold
It seems that automated floor-suckers are getting all the attention of late, as we've had users parading their Roombas around with all sorts of unorthodox methods, teaching them to bust a move, and now how to pose for the cameras. While already recognized in one Tokyo ceremony, the Fuji Heavy Industries and Sumitomo-created vacuum has officially taken the gold in the Robot of the Year competition hosted by the Japanese Ministry of Economy, Trade, and Industry. Due to its purported ability to replace "two live human beings" and clean out an area of "3,000 square meters in four hours on a single charge," the jumbo-sized Roomba wannabe can help those towering skyscrapers stay clean in a bustling world. Additionally, it can maneuver up and down floors, in and out of elevators, and around crowded workspaces with ease, but we're not exactly sure how many decibels of noise this thing cranks out while taking care of business. Nevertheless, the co-founders are selling the device for a whopping ¥20 million ($168, 011), but still claim that it will more than pay for itself after a decade or so -- you know, since it doesn't beg for health insurance or anything.[Via Plastic Bamboo]
Finger vein scanner will unlock your door
We're not really sure why a good ol' fingerprint reader wouldn't do the trick (oh, wait), but apparently Sumitomo and Hitachi decided what the world really needs is a finger vein reader to lock and unlock doors. While this exact technology is certainly not brand new, this particular implementation seems to be. From what we can tell, you place your fingertips on the reader, and presto, the door unlocks, assuming your veins match its stored list of 10 authorized patterns. According to Plastic Bamboo, it'll cost ¥150,000 ($1,280) -- but, at that price, we'll stick to the tried-and-true analog deadbolt method.
