Robots that use Wi-Fi to see through walls

Robots created by a team working at the University of California, Santa Barbara are able to look through solid walls using just Wi-Fi signals. With potential applications in search and rescue, surveillance, detection and archeology, these robots have the capability to identify the position and outline of unseen objects within a scanned structure, and then categorize their composition as metal, timber, or flesh.

Researchers eliminate need for external power in Wi-Fi connectivity system

One of the advantages of the "connected world" is that myriad different devices can interact with each other over Wi-Fi to exchange data, control equipment, and generally lay the foundations of the Internet of Things of the not-too-distant future. Unfortunately, on the downside, all of the Wi-Fi connections need power to operate, and this severely restricts the pervasiveness of this technology. However, researchers at the University of Washington have developed a system that they say eliminates the need for power supplies for these connections by using what is known as radio frequency (RF) backscatter technology.Read More

New drone antenna expands Wi-Fi range for disaster-struck areas

Researchers from the University of North Texas (UNT) have demonstrated an unmanned aerial vehicle (UAV) capable of supplying Wi-Fi to disaster-struck areas with a range of up to 5 km (3.1 miles). The team says these figures represent a marked improvement on existing solutions and could lead to new forms of wireless communication. Read More

Vive aims to help avoid alcohol-fueled social dangers

Like a lot of us, young people like to party. But being under the influence of alcohol in an unfamiliar environment or in crowds of strangers can reduce their ability to protect themselves or make safe choices, particularly when they become separated from their friends. In an attempt to reduce the danger, a group of University of Washington students have designed a smart wearable that automatically alerts friends if something may be wrong.Read More

Students develop drone to locate survivors via their mobile phones

These days, most people are inseparable from their mobile phone, with the device being one of the essentials along with keys and cash or cards that people don't leave home without. A project at EPFL's Mobile Communications Laboratory is looking to take advantage of this fact by developing a drone that would help rescuers search for victims of natural disasters by locating their phones.Read More
