The EPFL system is able to track and identify individual players on crowded sports fields ...

Even for diehard sports fanatics, it can sometimes be quite difficult to tell which player is which, when watching a field, court or rink full of team athletes. While this can be merely frustrating for fans, it can have larger ramifications for referees or coaches, whose jobs depend on being able to know which players are doing what, at what time. Scientists from Switzerland’s École Polytechnique Fédérale de Lausanne (EPFL) have devised what could be a solution to that problem – it’s a system that continuously tracks each player, superimposing their number and jersey color over top of their image, on a computer screen.  Read More

The virtual arm controlled by a monkey selects an object based on its virtual texture

In a development that could have huge implications for quadriplegics, paraplegics and those with prosthetic limbs, researchers from Duke University and the Ecole Polytechnic Federale de Lausanne (EPFL) have developed technology that has allowed monkeys to control a virtual arm and touch and feel virtual objects using only their brain activity. The researchers say it is the first-ever demonstration of a two-way interaction between a primate brain and a virtual body and could lead to robotic exoskeletons that not only that allows paralyzed patients to walk again, but to also feel the ground beneath them.  Read More

Pix4D is a program that creates 3D aerial images by combining hundreds of 2D photographs, ...

While Google Earth can be extremely useful - not to mention a lot of fun - it now has some competition in the form of Pix4D. Instead of satellites, the imaging system uses a small, relatively inexpensive unmanned aerial vehicle (UAV) to acquire several hundred 2D photographs of a given geographical area. Those photos are then merged into one image, which users can explore in three dimensions on a computer screen.  Read More

Scientists are creating a brain-computer interface that will allow users to control device...

Practical thought-controlled devices, such as wheelchairs, artificial arms, or even cars, are perhaps a step closer to reality thanks to research being carried out at Switzerland’s Ecole Polytechnique Fédérale de Lausanne (EPFL). Traditionally, brain-computer interfaces require the user to concentrate on constantly maintaining a mental command of either turn left, turn right, or no-command (go straight). According to EPFL, most users can’t sustain more than about an hour of the necessary mental effort. The school is developing a new system, however, that allows users to take breaks and shift their attention to other things while their thought-controlled device continues to operate on its own.  Read More

A Stryker lies on its side following a buried IED blast in Iraq in 2007

Improvised Explosive Devices (IEDs) have attracted a lot of attention as a result of their use in Iraq and Afghanistan, but IEDs are used by guerillas and terrorist groups in many parts of the world, including Colombia. Being sensitive to the problem of IEDs, two Colombian doctoral students from the Ecole Polytechnique Federale de Lausanne (EPFL) set about looking for a way to explode such devices at a distance. In collaboration with two Colombian Universities the EPFL students developed a device that can explode IEDs remotely by using energy from their electromagnetic impulses.  Read More

Molybdenite could be used to make smaller and more energy efficient transistors

Researchers have uncovered a material that they say has distinct advantages over traditional silicon and even graphene for use in electronics. Called molybdenite (MoS2), this mineral is abundant in nature and is commonly used as an element in steel alloys or, thanks to its similarity in appearance and feel to graphite, as an additive in lubricant. But the mineral hadn’t been studied for use in electronics, which appears to have been an oversight with new research showing that molybdenite is a very effective semiconductor that could enable smaller and more energy efficient transistors, computer chips and solar cells.  Read More

Researchers have developed a camera system that snaps multi-gigabit images at 30 frames pe...

Cameras that can shoot 3D images are nothing new, but they don't really capture three dimensional moments at all - they actually record images in stereoscopic format, using two 2D images to create the illusion of depth. These photos and videos certainly offer a departure from their conventional two dimensional counterparts, but if you shift your view point, the picture remains the same. Researchers from Ecole Polytechnique Fédérale de Lausanne (EPFL) hope to change all that with the development of a strange-looking camera that snaps 360 degrees of simultaneous images and then reconstructs the images in 3D.  Read More

The MPQ/EPFL microresonator, which couples light with vibrations (Photo: EPFL)

Researchers from Germany’s Max Planck Institute of Quantum Optics (MPQ) and the Swiss Ecole Polytechnique Federale de Lausanne (EPFL) have created a microresonator that produces vibrations from laser light. The device also uses one laser beam to control the intensity of another, thus making it essentially an optical transistor. The technology could have big implications in fields such as telecommunications.  Read More

A diagram of nanowires used in a Racetrack memory chip

Tired of waiting for your computer to boot up? Within five to seven years, you may no longer have to. That’s the estimated amount of time it will take to bring Racetrack Memory to market. Racetrack is a proposed new shock-proof system that is said to be 100,000 times faster than current hard drives, while also being 300 times more energy-efficient. Although it incorporates cutting-edge nanotechnology, it’s based on the same principles as the humble VHS videotape.  Read More

Dr. Heike Riel, who leads the nanoscale electronics group at IBM Research-Zurich, is part ...

It has been estimated that in the European Union, about ten percent of the electricity used in homes and offices goes to power computers and other electronic devices that are in standby mode. By 2020, that amount could constitute 49 terawatt hours per year, which is almost equivalent to the combined annual electrical consumption of Austria, the Czech Republic and Portugal. The European Union’s just-announced Steeper research initiative squarely addresses such concerns. Its aim is to develop electronics that operate on less than half a volt when in standby, and that are up to ten times more energy-efficient when active.  Read More
