The US Postal Service (USPS) delivers an estimated 146 billion pieces of mail annually, including 6 billion packages. In an attempt to process package data more efficiently, USPS is experimenting with AI. Today, NVIDIA announced that it will provide USPS with its AI tech. NVIDIA claims its system will process package data 10-times faster and with higher accuracy.
NC State's new efficient pico projector raises hopes for smartphone cinema
A team at North Carolina State University has developed a new liquid crystal projector that could spell the end of bulky and noisy cinema gear. Conventional tech passes unpolarized light through a filter, but the process is so inefficient that nearly 50 percent of the energy is wasted just keeping things cool. Fortunately, the Wolfpack and ImagineOptix filter claims to be 90 percent efficient -- meaning that future projectors could be far sleeker. It's also a good sign for future smartphone pico projectors, although we're not sure how the owners of our local theater will feel when we start undercutting them with just a phone and a white wall.

Magellan's new RoadMate 5190T helps truckers find their way, like the do-dah man
Truckin'? Got your chips cashed in? Well then you might wanna put them toward the latest RoadMate GPS navigator from Magellan. Designed for commercial truck, bus and taxi operators, the company's new RoadMate 5190T boasts a five-inch color display that drivers can use to find the most pain-free routes from point A to point B. With the 5190T strapped to their dashboards, truckers will be able to set up customized routing based on their vehicles' precise specifications, while using Magellan's Highway Lane Assist feature to help negotiate more baroque highway interchanges or exits. The onboard information dashboard, meanwhile, provides constant updates on trucking speed limits, alerting drivers whenever they drift above a given threshold. There's also a tracking log that allows operators to store information on mileage, hours and other parameters, as well as a built-in speaker system that projects sound at up to 93 decibels. The device is priced at $380, though Magellan has yet to announce a launch date.
Researchers put smartphones on a power diet, drastically improve battery life
Nokia's Asha handsets already use browser compression to reduce data costs and power consumption for customers in the developing world, but the company's Finnish neighbours over at Aalto University have taken a totally different approach. By using a network proxy to squash traffic into bursts rather than a constant bit rate, and by forcing a smartphone's modem into idle mode between each burst, the researchers claim they can cut 3G power consumption by 74 percent. Now, we're fortunate enough to be surrounded by power outlets over here, but even we could use some of that.
Report: data centers accounted for just 1 to 1.5 percent of electricity use last year, Google claims less than 1 percent of that
You'd think, watching companies like Apple break ground on sprawling data centers, that the number of servers powering our untethered lives was on the rise. In a different decade, you might have been right. But not this one. According to a study prepared at the request of The New York Times, the number of servers in use has declined "significantly" since 2005. That's mostly because of the financial crisis of 2008, says lead researcher Jonathan G. Koomey of Stanford University, but we also can't discount the effect of more efficient technologies. What's more, he says, servers worldwide consume less energy than you might have guessed: they accounted for somewhere between 1 and 1.5 percent of global electricity use in 2010. And while Google, the king of cloud computing, has been cagey about revealing just how many servers house its treasure trove of data, the company said that of that 1 to 1.5 percent, it accounted for less than 1 percent -- meaning, just a hundredth of a percent of all the electricity consumed last year. All told, data centers' energy consumption has risen 56 percent since 2005 -- a far cry from the EPAs 2007 prediction that this figure would double by 2010, with annual costs ballooning to $7.4 billion. Then again, this slower-than-expected growth could well be temporary. Though Koomey can't specify to what extent the financial crisis and technological advancements are to blame, he insists, broadly speaking, that we're primarily seeing fallout from the economic slowdown -- a stay of execution, of sorts, for those of us rooting for energy conservation.
Intel adds to ULV processor line with 1.8GHz Core i7 and i5 options, one of them to star in ASUS UX21
Intel's so-called Ultrabooks may be a little way off into the distance at the moment, but the company isn't making you wait until its Ivy Bridge rollout to get a taste for ultraslim laptops with some real power inside them. A trio of new ultra-low voltage CPUs, each rated with a TDP of just 17W, has been added to the company's catalog, starting with the top-tier Core i7-2677M, whose pair of cores run at 1.8GHz by default but can be sped up to 2.9GHz when duty calls. Then there's the i7-2637M, which looks to only differ in clock speeds (1.7GHz default, 2.8GHz under Turbo Boost), and the i5-2557M that makes do with a 3MB L3 cache (1MB less than its i7 brethren) and a 1.7GHz / 2.7GHz speed range. All three 64-bit, 32nm processors also integrate a GPU (350MHz base clock, maxes out at 1.2GHz) within their walls, which is what makes their ascetic power consumption all the more impressive. OEMs should soon start splicing these new options into their next generation laptops, and while the obvious speculation centers around a MacBook Air refresh, CNET tells us the Core i5-2557M has already found a home in ASUS' upcoming UX21, a (purportedly) sub-$1,000 11.6-inch featherweight contender.
Mizzou Professor says nantenna solar sheet soaks up 90 percent of the sun's rays, puts sunscreen to shame
Photovoltaics suffer from gross inefficiency, despite incremental improvements in their power producing capabilities. According to research by a team led by a University of Missouri professor, however, newly developed nantenna-equipped solar sheets can reap more than 90 percent of the sun's bounty -- which is more than double the efficiency of existing solar technologies. Apparently, some "special high-speed electrical circuitry" is the secret sauce behind the solar breakthrough. Of course, the flexible film is currently a flight of fancy and won't be generating juice for the public anytime soon. The professor and his pals still need capital for commercialization, but they believe a product will be ready within five years. Take your time, guys, it's not like global warming's getting worse.

Google's Prediction API lets Fords learn all about you, tell you where to go
Earlier today, Google revealed plans to make our abodes more efficient and user friendly through Android automation, and it turns out they're helping Ford to do the same for our automobiles. You see, our driving habits affect the gas mileage we get, and if our cars could predict our preferred travel patterns they could optimize powertrain performance to max out our MPGs. That's why the Blue Oval Boys plan to use Google's Prediction API to learn our driving habits and combine that data with real time traffic info to make its cars increasingly efficient. The system isn't yet ready for showrooms, as there is work to be done securing the personal data and location awareness information it collects, but hopefully it won't be long before every new Ford can help us get from here to there with minimal fuel consumption. Here's hoping William Daniels is the one doling out the directions. %Gallery-123281%
Nanocones make solar cells more efficient, sinister looking
Going green is de rigeur, so the sun is becoming a much-preferred source of power. However, solar cells' inefficient harvesting of heliacal energies is a major reason they haven't usurped the power of petroleum. Good thing the big brains at Oak Ridge National Laboratory are looking to change that with nanocone-based solar technology. The teeny-tiny cones are made of zinc oxide and create "an intrinsic electric field distribution" to improve electrical charge transport within solar cells. We aren't sure what that means, but we do know the prickly-looking design provides a 3.2 percent light-to-power conversion efficiency that's a substantial improvement over the meager 1.8 percent offered by today's flat photovoltaics made of similar materials. That's 80 percent more efficient, and 100 percent more awesome.
IE9 is the most energy-efficient modern browser, according to Microsoft's own testing
Of all the battlefields we've witnessed in the browser wars, this one's never really crossed our minds before: energy efficiency. Yes, the power efficiency of a piece of software, not hardware, is being touted by Microsoft as a differentiating feature for its fresh new Internet Explorer 9. It's thrown together the top five most popular browsers and put them through a cycle of benchmarks -- including Microsoft's own FishIE Tank graphics acceleration test, but not the somewhat popular Adobe Flash -- while measuring how much power they use beyond what the underlying Windows 7 system needs to keep itself going. Shockingly, IE9 was the winner each and every time and there's a tenuous conclusion drawn that if you want good battery life, you'll be going with Internet Explorer. Oh well, whether you consider them a good laugh or really valuable buyer's advice, there's plenty more of these power consumption comparisons at the source link below.
Scientists improve blue OLED efficiency, don't promise everlasting light
Although this is not the first time we've seen an efficiency increase in blue OLEDs, it's worth noting that their proposed cap of productivity up to this point was a lowly five percent. It's exciting to learn, therefore, about a breakthrough by professor John Kieffer and graduate student Changgua Zhen from the University of Michigan, which has resulted in them successfully increasing azure diode power efficiency by 100 percent. The duo, accompanied by some bright minds in Singapore, manipulated performance controllers by rearranging OLED molecules in a computer model, improving material characteristics. In simple terms though, we're still looking at a measly ten percent efficiency, so we'll see where they take it from here.
ST-Ericsson's PM2300 will charge smartphones and tablets twice as fast, speeding to market this fall
We can't say the methods for charging mobile devices have been top of our agenda lately, but when you're talking about speeding anything up by 100 percent, our interest is inevitably piqued. ST-Ericsson has come up with a new charger, tailored specifically for servicing tablets and mobile phones, that can juice them up at the brisk rate of 3 Amps. Efficiency is touted all over the place with this accessory, from the 60 percent improvement in PCB utilization to the 92 percent maximum power throughput rating, bringing the drably titled PM2300 dangerously close to a state of desirability. Best of all, tablets featuring its promised double-speed refilling capabilities are expected in the fall of this year, so the wait won't be long, however you look at it. [Thanks, Ola]
Boeing's biggest jet takes flight, promises lowest 'seat mile' cost of any commercial airliner
Boeing took a huge -- both literally and figuratively -- step in the development of the largest commercial jet in its history when the 747-8 took to the skies for the first time. Granted, the airframe's cargo version has already logged over 1,600 hours up in the air, but putting the 250-foot passenger plane with a 224-foot wingspan -- 19 feet longer and 13 feet wider than the gargantuan 747-400 -- through its first few paces without incident is no small feat. The 747-8 borrows some of the 787 Dreamliner's weight-trimming tech for better fuel efficiency and lower operational costs than older 747s and jumbo jet competition from Airbus. We just hope it didn't inherit the 787's penchant for delays as well. If all goes according to plan, the new jetliner should complete the 600 test flight hours needed for FAA certification in time to deliver the first 747-8s to customers by the end of the year. We doubt airlines will use the plane's extra space to give us shlubs riding coach any more legroom, but at least its improved all-around efficiency should make flying a little cheaper. PR's after the break.
NanoPhotonica develops S-QLED, OLED to develop inferiority complex soon
Ahh, the wonders of OLED -- flexible displays, great viewing angles, and low power consumption. However, the folks at NanoPhotonica have "perfected" a quantum dot display technology called S-QLED that allegedly has superior picture quality, uses 30 percent less power, and costs three-quarters less than its OLED competition. The company is gearing up for mass production and is in talks with several OEMs to start producing S-QLED displays, but unfortunately there's no timetable for when they'll get to market. Guess we'll have to wait a bit longer to see just how perfect these QLEDs really are.
LG and QD Vision unite for QLEDs: the quantum dot displays of our power-efficient future
Seems like LG really has a thing for those quantum dot LEDs. After hooking up with Nanosys earlier this year, the Korean giant is now stretching out another of its tentacles -- LG Display, to be specific -- for a partnership with a competing QLED designer in QD Vision. What's being promised by this joint venture falls right in line with your generic pipe dream -- better color accuracy than OLEDs, up to twice the power efficiency at a given color purity, and a cheap and straightforward manufacturing process. In fact, because QLEDs do not require the same glass substrate as most current display technologies, they offer unmatched flexibility (olé!) in terms of how and where they may be used. The only downer, and you had to know there would be one, is that QD Vision describes its tech as still in the "development stage," but hey, at least we have another cool acronym to add to our library.
AMD's Bobcat APU benchmarked: the age of the Atom is at an end
So small, and yet potentially so disruptive. AMD's 1.6GHz Zacate chip, bearing a pair of Bobcat modules, has been taken off the leash today, resulting in a torrent of benchmarks pouring down onto the internet. While perusing the sources below, you might think to yourself that it's not exactly a world beater, sitting somewhere in the middle of the pack on most tests, but compare it to Intel's dual-core Atom D510 -- its most immediate competition in the target sub-$500 laptop price range -- and you'll find a thoroughgoing whooping in progress. The highlight of these new Fusion APUs is that they integrate graphics processing within the CPU chip, and Zacate didn't disappoint on that front either, with marked improvements over anything else available in its class. The resulting chips might still not have quite enough grunt to earn a place in your daily workhorse mobile computer, but their power efficiency and netbook-level pricing goals sure do look delightful. Or dangerous, if you're Intel. Read - AnandTech Read - Tech Report Read - PC Perspective Read - Hot Hardware Read - Legit Reviews
AMD teases Bobcat Fusion APUs again, delivers Atom-busting performance (video)
A quick refresher: Bobcat is AMD's low-power Accelerated Processing Unit that can handle both computational and graphical duties, Ontario and Zacate are the chips built upon that core, and Brazos is the overall platform that they'll be doing their work on. Clear enough? We hope so. AMD has finally allowed a few tech pubs to get their hands on Brazos-based systems and, along with feedback about their experience, the guys have come back with some added spec notes. There'll be two initial Zacate options, the dual-core E-350 running at 1.6GHz or the single-core E-240 clocked at 1.5GHz, while Ontario will offer 1GHz dual-core and 1.2GHz single-core variants. Let's not forget that both are intended for netbooks and lithe desktop computers before writing them off as too slow -- which would be a mistake anyway as the sites that got a chance to play with the E-350 reported very respectable performance. HardOCP dared to try out Crysis and managed to get it chugging along at a resolution around 720p, whereas Hot Hardware witnessed a 1080p video clip being played back perfectly smoothly alongside an instance of Hyper Pi maxing out the CPU load. Benchmark results will have to wait for another day, but feel free to peruse the links below for a more detailed breakdown of the new architecture.
Microsoft details Vejle, the new Xbox 360's system-on-chip architecture
There aren't many unresolved mysteries with Microsoft's new console by this point -- apart from perhaps why it wasn't named the Stealthbox, like we were suggesting -- but one thing that hasn't been covered in excruciating detail yet is the new 360's splicing of the CPU and GPU into the same chip. Microsoft has remedied that today, informing us that the 45nm system-on-chip (codenamed Vejle; sorry, Valhalla fans) inside the refreshed Xbox makes do with a relatively minimal 372 million transistors, requiring only 40 percent of the power and less than 50 percent of the die space of its 2005 ancestor. A somewhat bemusing addition, noted by Ars, is the FSB Replacement sector you see in the image above. It's designed to induce lag in the system so that the Vejle chip doesn't run faster than the old stuff, something Microsoft couldn't allow to happen. Facepalm away, good people, facepalm away.
