NC State’s new efficient pico projector raises hopes for smartphone cinema

NC State's new efficient projector

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.

Researchers partially automate CPU core design, aim to fast track new PC processor production

NC State researchers automate CPU core design, potentially put new PC processors on the production fast trackTired of the year wait (or more) in between new silicon architecture offerings from Chipzilla and AMD? Well, if some Wolfpack researchers have anything to say about it, we'll measure that wait in months thanks to a new CPU core design tool that automates part of the process. Creating a new CPU core is, on a high level, a two step procedure. First, the architectural specification is created, which sets the core's dimensions and arranges its components. That requires some heavy intellectual lifting, and involves teams of engineers to complete. Previously, similar manpower was needed for the second step, where the architecture spec is translated into an implementation design that can be fabricated in a factory. No longer. The aforementioned NC State boffins have come up with a tool that allows engineers to input their architecture specification, and it generates an implementation design that's used to draw up manufacturing blueprints. The result? Considerable time and manpower savings in creating newly designed CPU cores, which means that all those leaked roadmaps we're so fond of could be in serious need of revision sometime soon.

Mobile security researchers present Android Malware Genome Project at IEEE

Posted on by

Mobile security researchers announce Android Malware Genome Project at IEEEAndroid's openness, combined with its popularity, has lead a few of the developer faithful astray -- with malware being a legitimate concern for the mobile operating system. To help combat the issue, Xuxian Jiang, an NC State researcher, has created the Android Malware Genome Project, which was presented at the IEEE Symposium on Security this week. The aim is to collect and analyse all the known malicious software, and share the findings so that more effective and preventative measures to be taken by the community. Jiang claims that the main drawback has been understanding the malware, and getting access to examples, something the project aims to solve. More than 1,200 malware samples have been collected so far, and if you're curious, the dataset is available for download via the source.

Scientists tweak wireless power transfer, Tesla nods happily in his grave

Wireless charging may be all the rage these days, but actually beaming electricity -- as sketched above by the man Tesla himself -- still has some snags. North Carolina State U researchers have found a way to possibly vanquish the biggest problem: the difficulty of exactly matching resonant frequencies to amplify current. If external factors like temperature change the tuning of a transmitter even slightly then power drops will occur, but circuitry developed by the NC State scientists would allow receivers to detect these changes and automatically re-tune themselves to match. This could make for more potent car and device charging in the future and, if they stretch the distances a bit, maybe we'll finally get the wire-free utopia Nikola dreamed up 120 years ago.

NC State researcher finds more efficient way to cool devices, looks to cut costs too

NC State researcher finds more efficient way to cool devices, looks to cut costs too
Does your electronic device have you a bit hot under the collar these days? A researcher at NC State has developed a faster and less expensive method for cooling gadgets -- especially those that tend to crank the heat up. Dr. Jag Kasichainula, an Associate Professor of Materials Science and Engineering, authored a paper on the research that implements a "heat spreader' composed of a copper-graphene composite and an indium-graphene interface film to cool devices. Because the two materials exhibit a high thermal conductivity, they allow the device to cool more efficiently while distributing said heat -- 25 percent quicker than the pure copper in many pieces of tech. And if that wasn't enough, the research also details the process for creating the composite using electrochemical deposition. "Copper is expensive, so replacing some of the copper with graphene actually lowers the overall cost.," Kasichainula notes. If you're itching to read a full rundown of the findings, the full text can be accessed via the source link below.
