Dell Introduces Latitude 12 Rugged Tablet
Dell has announced the Latitude 12 Rugged Tablet, "built to survive drops and dirty environments." It is the first tablet to join the Rugged line from Dell and "can withstand drops from over 4 feet, spills in water, mud, sand, and dust, as well as temperatures from -20 to 145 degrees Fahrenheit." The tablet is powered by Windows 8.1 and features an 11.6" screen with 1366x768 resolution, a fifth generation Intel Core M CPU, up to 512GB of SSD storage, and up to 8GB of RAM. The Latitude 12 Rugged will be available by the end of the month with an expected cost between $1,600 and $2,000.

Early Details Revealed for NVIDIA Pascal GPU
The next big GPU to come out of NVIDIA is known as Pascal and is currently code named GP100. This continues the practice of naming GPUs after famous scientists and will be the first NVIDIA chip built using Taiwan Semiconductors 16nm FinFET process. The card is expected to release late next year in two variations, both using a 4096-bit memory bus. The GP100 cards will use stacked HBM2 memory at a frequency of 1GHz with a different number of DRAM stacks on each card. A consumer grade card will use four HBM2 stacks while Quadro and TESLA cards will use eight stacks. The 16nm FinFET process from TSMC will deliver improved power efficiency and a "considerable improvement" in transistor density.

Optical Absorbers Made Invisible to Other Frequencies
The ability to manipulate electromagnetic radiation has been transformative for the world, as absorbers and sensors have enabled various technologies. Traditionally these absorbers also reflect light, so while they only absorb one frequency, they interfere with several. Researchers at Aalto University have found a solution to this problem and built a transparent absorber.
The new absorber contains an array of helical elements that are tuned to absorb only a specific frequency of light, so others are able to pass right through. This allows the absorber to be invisible to other frequencies, which will make it valuable for radio astronomy as well as stealth technologies. Regular consumer could also benefit from this discovery, as the absorber could be made into cellphone screens that capture cell signals without blocking Wi-Fi and other transmissions.

Hardware Roundup: Tuesday, July 21, 2015, Edition
Another Tuesday has arrived, and with it comes a couple of items for your viewing pleasure. We have a review of the Tesoro Excalibur Spetrum keyboard, a mechanical model with RGB illumination on the keys and Kailh switches. There is also a look at the LUXA2 Smart Clip and Tab Clip, with the Smart Clip able to hold smartphones between 3.5" and 6", and the Tab Clip for tablets between 6" and 10".

How High-Frequency Electrons Behave in Graphene Discovered
Everyone wants data to move faster and faster, which is easier to request than to achieve as new devices have to be created that can operate at these higher speeds. One avenue to creating these devices is to use graphene, but first its behavior at these high speeds has to be determined. Researchers at the Institute of Photonic Sciences have discovered that apparently the mechanics involved are not very complicated.
Graphene is an atom-thick sheet of carbon atoms with extraordinary optical and electrical properties that could make it ideal of optical communications. To test it the researchers applied electric fields to it that were oscillating in the terahertz range of frequencies. They found that the electrical current passing through the graphene at these ultrafast speeds were very efficiency converted to electron heat. This mirrors what happens in a hot gas, which is a fairly simple thermodynamic phenomenon. The better understanding this discovery brings with it should improve the performance of future electronic and optical graphene-based devices in the future, such as photodetectors and ultra-high speed transistors.
