Seafloor fiber optic cables can listen for earthquakes

Posted by in categories: electronics, internet

Some 70% of Earth’s surface is covered by water, and yet nearly all earthquake detectors are on land. Aside from some expensive battery-powered sensors dropped to the sea floor and later retrieved, and a few arrays of near-shore detectors connected to land, seismologists have no way of monitoring the quakes that ripple through the sea floor and sometimes create tsunamis. Now, a technique described online in Science this week promises to take advantage of more than 1 million kilometers of fiber optic cables that crisscross the ocean floors and carry the world’s internet and telecom traffic. By looking for tiny changes in an optical signal running along the cable, scientists can detect and potentially locate earthquakes. The technique requires little more than lasers at each end of the cable and access to a small portion of the cable’s bandwidth. Crucially, it requires no modification to the cable itself and does not interfere with its everyday use.

Study opens a new route to achieving invisibility without using metamaterials

Posted by in categories: electronics, materials

A pair of researchers at Tokyo Institute of Technology (Tokyo Tech) describes a way of making a submicron-sized cylinder disappear without using any specialized coating. Their findings could enable invisibility of natural materials at optical frequency and eventually lead to a simpler way of enhancing optoelectronic devices, including sensing and communication technologies.

Making objects invisible is no longer the stuff of fantasy but a fast-evolving science. ‘Invisibility cloaks’ using metamaterials—engineered materials that can bend rays of light around an object to make it undetectable—now exist, and are beginning to be used to improve the performance of satellite antennas and sensors. Many of the proposed metamaterials however only work at limited wavelength ranges such as microwave frequencies.

Now, Kotaro Kajikawa and Yusuke Kobayashi of Tokyo Tech’s Department of Electrical and Electronic Engineering report a way of making a without a cloak for monochromatic illumination at optical frequency—a broader range of wavelengths, including those visible to the human eye.

Fit to drive? The car will judge

Posted by in categories: electronics, robotics/AI, transportation

However, we are not there yet and we have to take it step-by-step, says Dr Anna Anund from the Swedish National Road and Transport Research Institute (VTI). She and her team are developing sensor-based systems as part of the ADAS&ME project to move towards level three, in which the driver can rest and would only be expected to drive when the car requests it.


When you’re sleepy, stressed or have had a few drinks, you’re not in the best position to drive – or even make that decision. But automated cars could soon make that call for you.

Unboxing The Mind Bending Wallpaper TV… — YouTube

Posted by in categories: electronics, mobile phones

The LG Wallpaper TV is the thinnest display I’ve ever seen or held. It’s thinner than a smartphone and I can easily pick up the 65-inch! It uses LG’s OLED technology so you’ve got super dark blacks, vibrant colors and the overall picture quality you’ve come to expect from OLED. Because the Wallpaper TV is so thin it connects to an external sound bar speaker for power and video connections. The speaker is louder than standard TV speakers and features Dolby Atmos capabilities.

New discovery makes fast-charging, better performing lithium-ion batteries possible

Posted by in categories: electronics, transportation

Creating a lithium-ion battery that can charge in a matter of minutes but still operate at a high capacity is possible, according to research from Rensselaer Polytechnic Institute just published in Nature Communications. This development has the potential to improve battery performance for consumer electronics, solar grid storage, and electric vehicles.
