BT Runs an 800Gbps Channel On Old Fiber

judgecorp writes “BT has demonstrated an 800Gbps ‘superchannel’ on a 410km fiber in its core network, which was not able to carry 10Gbps channels using older technology. The superchannel is an advanced dense wave division multiplexing (DWDM) technique, created by combining multiple coherent optical signals into one channel, which had previously been shown in laboratory tests. BT ran the test on a fiber with optical characteristics (high polarization mode dispersion) that made it unsuitable for 10GBps using current techniques. That’s a good result for BT, because it means its existing core fiber network can be upgraded to handle more data. It’s also a good customer story for Ciena, which makes the optical switches used in the test.” Read more of this story at Slashdot.

College Students Invent a Shoe That Generates Electricity with Every Step

Undergraduate mechanical engineering students at Rice University built a shoe that recovers and stores energy generated by walking. This energy could be used to power small electronic devices, such as cell phones: The Agitation Squad – Carlos Armada, Julian Castro, David Morilla and Tyler Wiest – decided last fall to focus their attention on where the rubber meets the road to create a shoe-mounted generator. Another device to draw energy from the motion of the knee had already been developed and patented and led them to analyze other sources of energy. Working with the Motion Analysis Laboratory at Shriners Hospital for Children in Houston, the team determined the force at the heel delivered far more potential for power than any other part of the foot. “We went to the lab and saw the force distribution across the bottom of your foot, to see where the most force is felt,” Morilla said. “We found it would be at the heel and at the balls of your toes, as you push off. We went with the heel because, unless you’re sprinting, you’re letting gravity do the work.” […] The prototypes deliver an average of 400 milliwatts, enough to charge a battery, in benchtop tests (and a little less in walking tests, where the moving parts don’t move as far). They send energy through wires to a belt-mounted battery pack. A voltage regulator keeps it flowing steadily to the battery. The PediPower hits the ground before any other part of the prototype shoe. A lever arm strikes first. It is attached to a gearbox that replaces much of the shoe’s sole and turns the gears a little with each step. The gears drive a motor mounted on the outside of the shoe that generates electricity to send up to the battery. You can watch a video of their device at the link. Link -via Inhabitat

LEDs in an Engagement Ring

Ben’s engagement ring is awesome not only because it lights up, but because it lights up when he and his girlfriend hold hands: Putting a battery of capacitor inside a ring is nigh impossible, so [Ben] decided to power the LEDs with an inductive charging circuit. A coil of wire wound around kapton tape serves as the inductor and a small SMD capacitor powers three very bright and very tiny LEDs. The inductive charging unit itself is a masterpiece of hackery; [Ben] wanted the ring to light up whenever he and his ladyfriend were holding hands. To do this, [Ben]‘s inductive charger is also a wearable device: a large coil of wire is the charger’s transformer and was would to fit around [Ben]‘s wrist. The entire charging circuit can be easily hidden under a jacket sleeve, making for a nearly magical light-up ring. You can watch a video of the ring at the link. Link

Over 100 Hours of Video Uploaded To YouTube Every Minute

jones_supa writes “Google’s YouTube is celebrating its 8-year birthday, and at the same time they reveal some interesting numbers. ‘Today, more than 100 hours of video are uploaded to YouTube every minute. That’s more than four days of video uploaded each minute! Every month, more than 1 billion people come to YouTube to access news, answer questions and have a little fun. That’s almost one out of every two people on the Internet. Millions of partners are creating content for YouTube and more than 1,000 companies worldwide have mandated a one-hour mid-day break to watch nothing but funny YouTube videos. Well, we made that last stat up, but that would be cool (the other stats are true).'” Read more of this story at Slashdot.

Medical Firm Sues IRS For 4th Amendment Violation In Records Seizure

cold fjord writes “A healthcare provider has sued the Internal Revenue Service and 15 of its agents, charging they wrongfully seized 60 million medical records from 10 million Americans … [The unnamed company alleges] the agency violated the Fourth Amendment in 2011, when agents executed a search warrant for financial data on one employee – and that led to the seizure of information on 10 million, including state judges. The search warrant did not specify that the IRS could take medical information, UPI said. And information technology officials warned the IRS about the potential to violate medical privacy laws before agents executed the warrant, the complaint said.” Also at Nextgov.com.
