Data hurtle down fiber-optic cables at frequencies of several terahertz. As soon as the data arrive on a PC or television, this speed must be throttled to match the data processing speed of the device components, which currently is in the range of a few hundred gigahertz only. Researchers have now developed a technology that can process the data up to hundred times faster and thus close the gap between the transport and processing speeds.
Mobile phones and tablets through so-called audio tracking, can be used by means of ultrasound to unnoticeably track the behaviour of their users: for example, viewing certain videos or staying in specific rooms and places. In the project SoniControl, St. Pölten University of Applied Sciences has developed a method for how this undetected (and usually unwanted) spying can be exposed and blocked. The result is the world's first ultrasound-firewall, which is now available for free in the app store.
Anticipating a critical strain on the ability of fifth generation (5G) networks to keep track of a rapidly growing number of mobile devices, engineers at Tufts University have come up with an improved algorithm for localizing and tracking these products that distributes the task among the devices themselves. It is a scalable solution that could meet the demands of a projected 50 billion connected products in the Internet-of-Things by 2020.
Physicists at Saarland University in Saarbrücken, Germany, have succeeded in entangling a single atom with a single photon in the telecom wavelength range. This constitutes a basic building block for transmission of quantum information over long distance with low loss. The results have raised great attention in the quantum technology community; now they are published in Nature Communications.
Graphene Flagship researchers created a technology that could lead to new devices for faster, more reliable ultra-broad bandwidth transfers. For the first time, researchers demonstrated how electrical fields boost the non-linear optical effects of graphene. The research, published in Nature Nanotechnology, was carried out by a team of Graphene Flagship partners led by the Cambridge Graphene Centre at the University of Cambridge in collaboration with Politecnico di Milano and IIT- Istituto Italiano di Tecnologia in Genova, both in Italy.
The future of electronic devices lies partly within the 'internet of things' -- the network of devices, vehicles and appliances embedded within electronics to enable connectivity and data exchange. University of Illinois engineers are helping realize this future by minimizing the size of one notoriously large element of integrated circuits used for wireless communication -- the transformer.
An optical communication system could revolutionize underwater exploration and discovery.
researchers have demonstrated a light-based device that mimics a fish's incredible jamming avoidance response (JAR) by moving the frequency of an emitted signal away from other signals that could potentially cause interference.
Engineering and physics researchers have developed a new technology for steering light that allows for more light input and greater efficiency -- a development that holds promise for creating more immersive augmented-reality display systems.
A joint research team from Tokyo Tech and North Carolina State University has clarified the fundamental principles for achieving the synchronization of power generator groups in power networks, which is essential for the stable supply of electric power. Based on this principle, the team developed a method for constructing an aggregated model of a power network that can efficiently analyze and control the behavior of generator groups (including rotor phase angles and connection point voltages) with complex connection to a power grid.
