As hard disk capacity increases from an increased number of disks, so does power consumption. However, Samsung’s F2EG drive offers low power consumption by using EcoTriangle, a low-power, low-heat, low-noise operation technology. With its advanced design and fewer components, the F2EG drive is 40% lower in power consumption in idle mode and 45% lower in reading/writing mode than competitive drives. Samsung’s Eco-Triangle™ technology offers more energy efficient and high performance hard drive options to manufacturers of home media PC, external HDD, set-top box, and personal NAS.

Previously, only a few memristor circuits had been demonstrated, rather than such a large-scale array, due to reliability and reproducibility issues. While 1 kilobit is not a huge amount of information, the researchers consider it a leap that will make it easier to scale the technology so it can store much more data.

"We demonstrated CMOS-compatible, ultra-high-density memory arrays based on a silicon memristive system. This is an important first step." said Wei Lu, an assistant professor in the Department of Electrical Engineering and Computer Science. CMOS stands for complementery metal oxide semiconductor. It is the technology used in modern microchips.

The density of a memristor-based memory chip could be at least an order of magnitude—a factor of 10—higher than current transistor-based chips. Such high density circuits can also be very fast, Lu says. You could save data to a memristor memory three orders of magnitude faster than saving to today's flash memory, for example.

Using the asynchronous circuit design technology, Epson has been able to:
1. Make a stable 8-bit microprocessor composed of 32,000 LTPS-TFTs,
2. Achieve energy consumption 70% lower than the synchronous design, and
3. Reduce electromagnetic radiation by 20dB.
The current invention is the first time in the world for an operational 8-bit asynchronous microprocessor to be formed on a flexible substrate.

It's a similar story in examining the clone army of knockoffs that are following in Apple's footsteps.

The Delve is an average phone. It's versatile and sturdy and comes with the online and multimedia features we've come to expect, such as playing music and browsing the Web.

But the interface - the software that lets you tell the phone what you want it to do - falls flat when comparing it to the genre-defining iPhone.

It's clunky and unsophisticated and feels artificially slow - especially when you're used to a superior product. And that's too bad because there are a few glimmers of brilliance in the Delve's design.

As fuel cells are becoming more popular due to their potential use in applications such as hydrogen-powered vehicles, auxiliary power systems, and electronic devices, the need for the precious metal platinum is also increasing. In fuel cells, platinum is often used as the catalyst for oxygen reduction by splitting oxygen molecules into oxygen ions. However, platinum is rare and expensive: in a fuel cell for a typical car, the platinum catalyst costs about $4,000.

Now, researchers from the University of Dayton have showed that carbon nanotubes can replace platinum as the catalyst in fuel cells, which could significantly reduce fuel cells' overall cost. Carbon nanotubes could even have advantages over platinum, since they could be less resistant to corrosion.

After all, Apple Inc.'s device, like other gadgets with touch-screen technology, will work only with the touch of an uncovered finger. So if you're wearing gloves, you have a dilemma: Bare your hands to use your beloved devices, or let calls, texts and e-mails go unanswered while
you're braving the elements? A company called 4sight Products Inc. has a solution: $40 gloves that have electrically conductive gold-colored material on the tip of the index finger and thumb. Apple must think it's a good idea as well - it has filed an application with the U.S. Patent and Trademark Office for gloves that would essentially do the same thing.
