AllSee prototype puts gesture recognition in your pocket

Current gesture recognition technology seen in devices such as Samsung's Galaxy S4 generally rely on the device's camera. This not only creates a drain on the device's battery, but means users need to retrieve the phone from their pocket or handbag to make use of the technology. The new AllSee system developed at the University of Washington (UW) overcomes both these problems by using wireless signals not only as a power source, but also to detect user gestures when the phone is tucked away out of sight.

Scientists create world's thinnest LEDs

In regular microchips, work is performed via the movement of electrons within the chip. Thanks to the recent creation of the thinnest-ever LEDs, however, such chips may one day be able to use light instead of electrons, saving power and reducing heat. Of course, those LEDs could also just be used as a really flat form of lighting, in any number of applications. Read More

Crashing rockets could lead to novel sample-return technology

The terms "auger in" and "lawndart" refer to rather exciting and decidedly dangerous methods of recovering a rocket, during which the screaming rocket buries its pointy end deep in the ground. Such over-enthusiastic landings provided a group of research students from the University of Washington (UWash) the inspiration for a new approach to collecting samples from hostile environments, such as the crater of an erupting volcano or a melting nuclear reactor.

Students crash rockets to develop new asteroid sample collection technique

In what at first glance seems like a terrible sense of direction, in March students from the University of Washington fired rockets from kites and balloons at an altitude of 3,000 ft (914 m) straight into the ground at Black Rock, Nevada: a dry lake bed in the desert 100 mi (160 km) north of Reno. This may seem like the ultimate in larking about, but it's actually a serious effort to develop new ways of collecting samples from asteroids. Read More

Cyclops has its eye on the deep blue sea

In three years, if you happen to be 3,000 meters (9,800 ft) beneath the surface of the ocean, keep an eye out for the Cyclops. No, not the hairy giant, but the 5-passenger submersible. Once it’s commercially available in 2016, it should be “the only privately owned deep-water manned submersible available for contracts.” As for why it’s called the Cyclops, just check out its one-big-eye-like 180-degree borosilicate glass observation dome.

Ambient backscatter tech allows devices to communicate, sans batteries

In order for the Internet of Things to become a reality, devices will need to be able to communicate with the internet and with one another. If they have to be powered up in order to so, however, a lot of electricity is going to be wasted. That’s where a new technology known as “ambient backscatter” comes into the picture. Developed by engineers at the University of Washington, it uses ever-present existing TV and cellular signals to provide the power and medium for battery-less communications. Read More
