Economies of scale mean that densely populated cities have generally been the ones to benefit from the roll out of superfast broadband networks, while those in rural areas have missed out. Following Google's recent announcement that it will build and test 1Gbps fiber-to-the-home (FTTH) networks
in selected cities with between 50,000 to 500,000 residents in the U.S. starting with Kansas City, Kansas
has unveiled plans to create a similar superfast FTTH broadband network for five million homes and businesses in rural Britain to bridge the digital divide between city and country.
Many of us can now wirelessly stream images from a computer to a screen over Bluetooth or Wi-Fi without too much trouble, but the display is still inevitably powered by cables. At CeBIT 2011
, Fujitsu is showing off a working prototype of a 22-inch computer display that receives both images and power wirelessly. The power transfer is made possible by magnetic induction technology
– similar to Powermat chargers
– that's concentrated into hotspots built into office furniture or conference tables.
Last year, Fujitsu introduced a keyboard where nearly half of the plastic normally used was replaced with biodegradable bio- or wood-based substitutes. The company continues its green crusade this year with the introduction of what's claimed to be the world's first biodegradable computer mouse. The M440 ECO optical mouse sports a PVC-free USB cable and is made from a combination of the same Arboform and Biograde materials used in the keyboard – reducing our dependence on oil-based resources one click at a time..
Fujitsu Laboratories today announced a two-in-one energy harvesting device that can convert both light and heat into electricity. With no electrical wiring or batteries to replace, Fujitsu says that this sort of device can be manufactured from organic materials keeping costs to a minimum.
Fujitsu Laboratories has unveiled a new optical switch technology that it claims uses half the power of conventional optical switches. The new optical waveguide switch uses photonics made from silicon germanium (SiGe) instead of pure-silicon semiconductor material. This technology will be the basis for a new generation of high-speed optical switches capable of operating across a wide range of wavelengths, while featuring perhaps the world’s lowest power requirements.
Fujitsu has announced a transmission power amplifier that is set to extend the transmission range of wireless communications networks by six times. The company's newly development gallium nitride (GaN) High Electron Mobility Transistor (HEMT) has achieved the world's highest output for wireless communications in the millimeter-wave W band.
At CEATEC 2010
in Chiba, Japan this past week, more than a few companies were showcasing tablet computers, due in no small part to the success of Apple's iPad
. The most notable among them was the Samsung Galaxy Tab
It wasn't so long ago that we reported on the Roadrunner supercomputer breaking the petaflop barrier
. But this week Fujitsu announced that it will begin shipping its next-generation supercomputer which has a lofty performance goal of 10 petaflops – that's ten thousand trillion operations per second! The computer is nicknamed the 'K', a reference to the Japanese word "Kei," or 10 to the 16th power. If the K could reach this goal, it would hold the first place title – at least for a while – on top of the top 500 supercomputers list.
We're all aware of how annoying a tangled mass of electrical wires can be. Fortunately, a research effort from Fujitsu is tackling the problem at its very source. During a conference held in the Institute of Electronics, Information and Communication Engineers at Osaka Prefecture University, the Japanese electronics giant announced a major step in developing a wireless recharging technology that can work simultaneously with multiple portable devices.
Anyone who has suffered the very unpleasant experience that is food poisoning will be happy to hear that researchers have developed technology enabling the high-speed detection of the toxic proteins that cause it. The new sensor was manufactured by employing a combination of artificial antibodies which capture these toxic proteins and a signal converter which converts those “capturing events” into optical signals.
