Wireless Display on a Contact Lens

 Posted by: Wille D. Jones A team of researchers led by Babak Amir Parviz, an associate professor of electrical engineering at the University of Washington, just published a paper in the 22 November edition of the Journal of Micromechanics and Microengineering that described a breakthrough in the development of an electronic contact lens with a built-in display. Parviz, who collaborated with University of Washington ophthalmologist Tueng Shen and optoelectronics researchers from Aalto University in Finland, has for several years been working on contact lenses that will someday augment the wearer’s vision with external data or use...

Meet the New World's Fastest Micromouse Robot

 Posted by: Evan Ackerman   One year ago, we got super excited when a micromouse managed to negotiate a maze in under five seconds. At the 2011 All Japan Micromouse Robot Competition in Tsukuba, the micromouse pictured above shaved an entire second off of that time, completing the maze in a scant 3.921 seconds. That's fast. This robot, called Min7.1, was designed by Ng Beng Kiat. It has a top speed of just over 12 kph, which is wicked quick for something that's 10 cm long and weighs only 90 grams. Of course, the micromouse has to figure out where it's going before it can put the hammer down and blaze...

5 of the world's fastest supercomputers

The biannual Top 500 list, revised each June and November, shows that the fastest supercomputers are getting even faster. No. 1: K Computer The positions haven't shifted, but there were plenty of changes atop the list released Monday of the world's 500 fastest supercomputers. K Computer, which became the world's fastest supercomputer by a factor of three five months ago, has been upgraded and is now four times speedier than the next-fastest. It is more powerful than the next seven supercomputers combined. The supercomputer is capable of 10.51 Petaflops. That means it can do 10.51 quadrillion -- that's a million billion -- calculations...

Two reasons a network administrator would use CDP

Verify Layer 2 connectivity between two devices when Layer 3 fails. Obtain the IP address of a connected device in order to telnet to the device. Cisco Discovery Protocol (CDP) is primarily used to obtain protocol addresses of neighboring devices and discover the platform of those devices. CDP can also be used to show information about the interfaces your router uses. CDP is an independent media protocol and runs on all Cisco-manufactured devices including routers, bridges, access servers, and switches. It should be noted that CDP is a protocol which works on the layer2.  By default, multicast advertise is sent every 60 seconds...

Canon goes to Hollywood

 by Lori Grunin Those of you hoping that Canon's latest announcement, long-rumored to be a camera with extraspecial video capabilities, would be a 5D Mark III can now officially be disappointed. At about $20,000, this one ain't for the hobbyists or the still-images-firsters.    (Credit: Canon USA) The new series of cameras, dubbed Cinema EOS, consists of two models based around a new 4K Super35 CMOS sensor and incorporating the most current version of its Digic DV III image processor. The two models differ only by mount: the C300 PL uses a PL mount (developed by Arri for film cameras) and the C300 uses a Canon...
