drag2share: Arman Ahnood teases OLED display with solar cells, idealizes the self-sustaining smartphone

Plenty of effort is going into improving smartphone battery life, but only a few individuals are delving into radical realms to achieve the goal. Take for example, Arman Ahnood, a researcher at the London Centre for Nanotechnology, whose latest prototype uses solar cells to capture wasted energy from OLEDs. Similar to Wysips (which uses only ambient light), and equipment from UCLA (designed for LCDs), each project faces the unenviable task of making the smartphone a self-sustaining piece of gear.

Ahnood's handiwork relies on an array of solar cells that surround and sit beneath the phone's display. Currently, the system averages 11 percent efficiency in its energy capture, with a peak efficiency of 18 percent. Naturally, there are gains to be made. Of the light generated from OLEDs, Ahnood approximates that only 36 percent is actually projected outward. Critically speaking, this also suggests that similar power savings could be achieved with dimmer, more efficient displays, but we'll let that slide. As it stands, Ahnood's system is able to generate approximately five milliwatts of additional power, given a screen size of 3.7-inches. It's hardly sustainable, but if the creation lets us squeeze in a few more text messages on Friday night, we'll take it.

drag2share: Wall Street's Hottest Smartphone App Can Sniff Out Corporate Bankruptcies Long Before They Happen

One of the most widely-used and well-recognized measures of corporate credit risk is the Altman Z-Score, named after legendary NYU Stern Professor Edward Altman.

Specifically, the Altman Z-Score is used to predict the odds of bankruptcy.  (More details below.)

According to The Financial Professional's Post, Professor Altman and Business Compass LLC teamed up to develop a smartphone app so that credit analysts can carry the power of the Altman Z-Score in the palm of their hands.

Here's an intro to the Altman Z-Score App for Android video.  You can find more videos here.

You're probably wondering how the Altman Z-Score works.

First, it takes key financial measures such as current assets, current liabilities, intangible assets, sales, earnings before interest and tax, market cap, book value, total assets and total liabilities.  Then it will tell you the probability of default over a period of 1 to 10 years.

You can read more about Professor Altman's work here.

drag2share: Samsung aggressively aggregating acronyms as eMCP assembly activated

Source: http://www.engadget.com/2012/01/19/samsung-aggressively-aggregating-acronyms-as-emcp-assembly-activ/

Samsung's started foundries rolling for its new embedded multi-chip package memory for budget smartphones -- after the success of the high-end modules that were released in October. eMCP jams together 30-nanometer low-power DDR2 DRAM and 20-nanometer NAND flash memory into a single slice of silicon. In real terms, this means that there's a 4GB e-MMC (embedded MultiMediaCard) flash chip with a 256MB, 512MB or 768MB DDR2 DRAM module bolted on the side. According to the company, it'll consume 25 percent less power with 30 percent better performance, cost less to jam into your telephone and probably make you smell better, too. If you're starting your own phone company, or just curious about embedded systems, head past the break for the PR.

drag2share: Apple revamps iTunes U and intros dedicated app (video)

Source: http://www.engadget.com/2012/01/19/apple-revamps-itunes-u-and-intros-dedicated-app/

A facelift for iBooks wasn't the only change on Apple's agenda today, as the company's SVP Eddy Cue has just announced an overhaul of iTunes U. The service, mostly used as a means of delivering lectures to college students, has seen over 700 million downloads since its launch and is now gearing up to offer full online courses from the likes of Duke University, Yale, MIT, amongst others.

As an example of this new remote method of learning, the company demoed a Chemistry course at its event, showing an overview, syllabus, credits and even the professor's office hours. Tabs are placed along the right side of page with options for Info, Posts, Notes and Materials, allowing teachers to send updates direct to the app and students the ability to jot down important highlights. Wondering about integration? A simple tap on these pushed assignments will transport students direct to iBooks, where their specific coursework lies in wait and, once completed, can be crossed off on the provided task list.

The app can even be used for course registration, eliminating the frenzied rush typically associated with such events. It's all available to download on the App Store right now at no cost in 123 countries. So, if you're on Apple's participating list of schools and you're rocking an iPad, go ahead and get to virtually cracking those books.

Update: We've got our hands-on video up of the new iTunes U application!

drag2share: Intel's CPU Insurance Is an Overclocker's Wet Dream [Intel]

Source: http://gizmodo.com/5877447/intels-cpu-insurance-is-an-overclockers-wet-dream

Overclocking processors used to be extremely nerdy, but if anything it's becoming more common these days. For those intent on squeezing performance from their chip, Intel's new CPU insurance means getting it wrong needn't be that expensive.

Overclocking a CPU does bring performance increases, but it also brings extra heat which can damage the chip if you're not careful. That's why Intel is now offering a Performance Tuning Protection Plan for five of its CPUs, which bolts on additional coverage for overclocked processors on top of their standard 3-year warranty.

You can buy the insurance any time within a year from purchase, and the policy lasts three years. So, burn your chip out from overclocking, and it's replaced free of charge. Insurance is available for five unlocked processors, and the cost varies by model as follows:

Core i7 3960X ($35)
Core i7 3930K ($35)
Core i7 2700K ($25)
Core i7 2600K ($25)
Core i5 2500K ($20)

It seems pretty cheap. But then, maybe that means Intel doesn't expect to have to replace many. [Intel via CNET]
