Flexible batteries get the graphene treatment, could be cheaper than other bendy batts

By Christopher Trout posted Mar 2nd 2011 1:53AM We've been talking about flexible batteries for years now, but a team of Korean researchers have presented a new solution to bendable energy sources that is not only more powerful than standard lithium-ion batteries, but also potentially cheaper to produce than its malleable predecessors -- and unsurprisingly, everyone's favorite wonder material, graphene, is at the heart of the innovation. The rechargeable battery contains a vanadium-oxide cathode, grown on a sheet of graphene paper, an unidentified separator, and an anode made of lithium-coated graphene. According to the folks behind the new power source, it sports higher energy and power density, as well as a better cycle life than the literally stiff competition. Similar advances have also out-performed rigid lithium-ion batteries, but have enlisted carbon nanotubes, a material more expensive to produce than graphene. Of course, like all technological advances, we won't be seeing these things for years, if not decades, so you might as well get used to ye olde standard bearer.

Microsoft Research shows off next-generation gesture interfaces, Kinect integration, other neato stuff (video)

Leave it to Microsoft Research to show off some cool stuff that may or may not actually happen on any thing you ever actually buy. Check out the video after the break to see the latest, Director of Microsoft Applied Sciences Steven "Stevie B" Bathiche showing off a variety of interesting interfaces. It all starts with gesture controls that take you well beyond the touchscreen, relying on a retro-reflective sash and a camera to detect hand position. But, things quickly progress to a flat lens called a wedge that can enable holographic-like imagery. Pair that with a Kinect and perspective shifts come into play, tracking your face to enable you to peer around like looking out a window. It's all just waiting for you below -- and maybe IRL sometime in the future.

Samsung develops mobile DRAM capable of 12.8GB/sec data transfers, making all other memory jealous

Much like clockwork, Samsung's memory labs are cranking out yet another innovation in the mobile DRAM sector, with the goal being to make the next (next) generation Galaxy Tab -- and any other mobile device relying on Samsung memory -- faster than ever. This go 'round, the crew has developed a 1Gb mobile DRAM module with a wide I/O interface for smartphones and tablets, enabling it to transmit data at 12.8GB/sec. For those keeping count, that's an eightfold increase in bandwidth compared to LPDDR2 DRAM chips, and the company has also managed to trim power consumption by 87 percent all the while. In order to boost the data transfer rate, Samsung's new wide I/O DRAM uses 512 pins for input and output, dwarfing the 32 pins used in the previous generation. Following this, Sammy's hoping to provide 20nm-class 4Gb wide I/O mobile DRAM sometime in 2013, but we're hoping to see this particular development sashay into tablets that hit the market long before then. Sadly, there's no specific word on when, but you know we'll be handing that information over just as soon as we get it.

Samsung Develops Mobile DRAM with Wide I/O Interface

SEOUL, Korea--(BUSINESS WIRE)--Samsung Electronics Co., Ltd., the world leader in advanced memory technology, today announced the development of 1 gigabit (Gb) mobile DRAM with a wide I/O interface, using 50 nanometer class* process technology. The new wide I/O mobile DRAM will be used in mobile applications, such as smartphones and tablet PCs.

"We will continue to aggressively expand our high-performance mobile memory product line to further propel the growth of the mobile industry."

"Following the development of 4Gb LPDDR2 DRAM (low-power DDR2 dynamic random access memory) last year, our new mobile DRAM solution with a wide I/O interface represents a significant contribution to the advancement of high-performance mobile products," said Byungse So, senior vice president, memory product planning & application engineering at Samsung Electronics. "We will continue to aggressively expand our high-performance mobile memory product line to further propel the growth of the mobile industry."

The new 1Gb wide I/O mobile DRAM can transmit data at 12.8 gigabyte (GB) per second, which increases the bandwidth of mobile DDR DRAM (1.6GB/s) eightfold, while reducing power consumption by approximately 87 percent. The bandwidth is also four times that of LPDDR2 DRAM (which is approximately 3.2GB/s).

To boost data transmission, Samsung's wide I/O DRAM uses 512 pins for data input and output compared to the previous generation of mobile DRAMs, which used a maximum of 32 pins. If you include the pins that are involved in sending commands and regulating power supply, a single Samsung wide I/O DRAM is designed to accommodate approximately 1,200 pins.

Following this wide I/O DRAM launch, Samsung is aiming to provide 20nm-class* 4Gb wide I/O mobile DRAM sometime in 2013. The company's recent achievements in mobile DRAM include introducing the first 50nm-class 1Gb LPDDR2 DRAM in 2009 and the first 40nm-class* 2Gb LPDDR2 in 2010.

Samsung will present a paper related to wide I/O DRAM technology at the 2011 International Solid-State Circuits Conference (ISSCC) being held from February 20 to 24 in San Francisco.

According to iSuppli, mobile DRAM's percentage of total annual DRAM shipments will increase from about 11.1 percent in 2010 to 16.5 percent in 2014.

Watson wins it all, humans still can do some other cool things

By Paul Miller posted Feb 16th 2011 10:22PM In case you missed it, Watson won again tonight. He even got the Final Jeopardy question correct this time, a multi-layered reference to Bram Stroker that he bet $10k on. His final score over the two rounds ended up at $77,147 (Watson has this thing for betting strange amounts that usually end in a 7), while Ken Jennings got $24,000 and Brad Rutter did $21,600 -- both humans saving a bit of face after last round's stunning defeat. Watson will be giving his $1,000,000 winnings to charity.

So, a few things:
We're totally surprised, in a larger theoretical sense, that a computer could win at Jeopardy.We're totally not surprised that Watson, the system built by IBM over the past few years at the expense of millions of dollars, actually succeeded at winning at Jeopardy.Computers have better reflexes than humans, as it turns out.Deal with it.If you can't tell, we're having a little trouble processing all the emotions brought on by a Jeopardy win from IBM's Watson supercomputer. It's obvious that IBM's DeepQA research program has developed some of the most sophisticated natural language AI known to man. At the same time, Jeopardy questions aren't really that hard. As evidenced by watching these Watson-dominated matches, all three contestants knew the answer most of the time, but Watson was just quicker on the draw. Of course, it's no surprise that computers have quicker reflexes (even with the "handicap" of having to mechanically press the same style of clicker as Meatbag 001 and Meatbag 002), so why shouldn't Watson get to use his inbuilt advantage to the utmost? It seems like a fair fight to us.

The question of "who is better at Jeopardy" aside (trust us, it's Watson), the larger implications for the human race and our computer sidekicks are still unclear. Watson can currently answer simple trivia questions, sometimes couched in puns or minor riddles, with a decent level of accuracy. The answers themselves are no more than a high school student with Wikipedia access could pull off, and Watson has no way of knowing for sure when he's right. He lacks a solid, computer-readable database of "facts" like a Wolfram Alpha, or the incredible reasoning abilities of a human, instead relying on statistical analysis of vast amounts of text. When it comes to Jeopardy, it turns out to be Good Enough, which is actually a pretty incredible achievement in the world of AI, and we're sure we'll be finding out soon what other applications IBM thinks Watson is Good Enough at -- they're thinking everything from healthcare to the financial industry. Still, we're sure some of us clicker-speed-nit-pickers will remain unimpressed. Make sure to check out the Engadget Show tomorrow, where we'll be chatting up the creators of Watson about all this, but for now... 01000011 01101111 01101110 01100111 01110010 01100001 01110100 01110011 00100001
