Beyond Silicon: Next Generation Electronic Device

Beyond Silicon: Next Generation Electronic Device

In the consumer electronics industry, the mantra for innovation is higher device performance/less power. Arun Thathachary, a Ph.D. student in Penn State’s Electrical Engineering Department, spends his days and sometimes nights in the cleanroom of the Materials Research Institute’s Nanofabrication Laboratory trying to make innovative transistor devices out of materials other than the standard semiconductor [...]

Laser-Like Light Emission: Optical Resonators

Laser-Like Light Emission: Optical Resonators

By combining plasmonics and optical microresonators, researchers at the University of Illinois at Urbana-Champaign have created a new optical amplifier (or laser) design, paving the way for power-on-a-chip applications.   “We have made optical systems at the microscopic scale that amplify light and produce ultra-narrowband spectral output,” explained J. Gary Eden, a professor of electrical [...]

New Tool Makes a Single Picture Worth a Thousand – and more – Images

New Tool Makes a Single Picture Worth a Thousand – and more – Images

A photo is worth a thousand words, but what if the image could also represent thousands of other images?   New software developed by UC Berkeley computer scientists seeks to tame the vast amount of visual data in the world by generating a single photo that can represent massive clusters of images. This tool can [...]

Can Our Computers Get Smaller, More Powerful?

Can Our Computers Get Smaller, More Powerful?

From their origins in the 1940s as sequestered, room-sized machines designed for military and scientific use, computers have made a rapid march into the mainstream, radically transforming industry, commerce, entertainment and governance while shrinking to become ubiquitous handheld portals to the world.   This progress has been driven by the industry’s ability to continually innovate [...]

How Fast You Drive Might Reveal Exactly Where You Are Going

How Fast You Drive Might Reveal Exactly Where You Are Going

In our constantly connected, information-rich society, some drivers are jumping at the chance to let auto insurance companies monitor their driving habits in return for a handsome discount on their premiums. What these drivers may not know is that they could be revealing where they are driving, a privacy boundary that many would not consent [...]

Photo Editing Tool Enables Object Images To Be Manipulated in 3-D

Photo Editing Tool Enables Object Images To Be Manipulated in 3-D

Editors of photos routinely resize objects, or move them up, down or sideways, but Carnegie Mellon University researchers are adding an extra dimension to photo editing by enabling editors to turn or flip objects any way they want, even exposing surfaces not visible in the original photograph.   A chair in a photograph of a [...]

No-power Wi-Fi connectivity could fuel Internet of Things reality

No-power Wi-Fi connectivity could fuel Internet of Things reality

Imagine a world in which your wristwatch or other wearable device communicates directly with your online profiles, storing information about your daily activities where you can best access it – all without requiring batteries. Or, battery-free sensors embedded around your home could track minute-by-minute temperature changes and send that information to your thermostat to help [...]

Extracting Audio from Visual Information: Algorithm Recovers Speech from Vibrations of a Potato-Chip Bag Filmed through Soundproof Glass

Extracting Audio from Visual Information: Algorithm Recovers Speech from Vibrations of a Potato-Chip Bag Filmed through Soundproof Glass

Researchers at MIT, Microsoft, and Adobe have developed an algorithm that can reconstruct an audio signal by analyzing minute vibrations of objects depicted in video. In one set of experiments, they were able to recover intelligible speech from the vibrations of a potato-chip bag photographed from 15 feet away through soundproof glass.   In other [...]
