angry tapir writes "Japan's Sharp, a major supplier of LCD displays to Apple and other manufacturers, has warned that it may not survive if it can't turn around its business. The Osaka-based manufacturer said there is "material doubt" about its ability to continue operating in its earnings report filed Thursday. Sharp added, however, that it still believes it can cut costs and secure enough credit to survive. Its IGZO technology for mobile displays is likely to be a key element of its business strategy."

hypnosec writes "Two MIT electrical engineering professors, Joel Dawson and David Perreault, have claimed that they have cracked the age old efficiency problem related to the power amplifier in smartphones by designing a new amplifier that consumes just half the power as compared to their current counterparts. Current transistor-based power amplifiers consume power in two modes – standby and output signal mode. The only way to reduce power consumption and increase battery life is to use the least possible power when in standby mode. The problem here is that if the power is kept very low when in standby mode, because of sudden jumps from low-power standby mode to high-power output mode, signals get distorted. This is why current technologies waste a lot of electricity as standby power levels are kept at a relatively higher level to avoid distortion. The new technology, dubbed asymmetric multilevel outphasing, is basically a blazingly fast electronic gearbox that would select the best possible voltage to send across to the transistors that would minimize power consumption."

Makers attended from Shanghai, Beijing and Shenzhen and visitors came from around China. More photos are in this post, and videos in this one. Other photos can be found in this thread." I like the video that appears to show a smartphone's camera being used as the basis of an input device for a laptop; can anyone out there better explain it?
An anonymous reader writes with a link to this "time lapse video of students and postdocs at the University of Zurich constructing the zBox4 supercomputer. The machine has a theoretical compute capacity of ~1% of the human brain and will be used for simulating the formation of stars, planets and galaxies." That rack has "3,072 2.2GHz Intel Xeon cores and over 12TB of RAM." Also notable: for once, several of the YouTube comments are worth reading for more details on the construction and specs.
Zothecula writes "Embattled photovoltaic solar power manufacturer Amonix announced on Tuesday that it has broken the solar module efficiency record, becoming the first manufacturer to convert more than a third of incoming light energy into electricity – a goal once branded 'one third of a sun' in a Department of Energy initiative. The Amonix module clocked an efficiency rating of 33.5 percent."
jjp9999 writes "By using the same technology found in older modems, Thomas Tumino, vice president of the Hall of Science Amateur Radio Club, has invented an iPhone interface for ham radios. He told The Epoch Times, 'Today there are iPhone apps where you can use the systems in the phone — and its sound card, which is being used as a modem ... And then you connect that into your radio with an interface like this, that just isolates the telephone from the radio, and then you can do all sorts of things.'"
Nerval's Lobster writes "The local utility serving most of the New York City area, Con Edison, reported that it should begin supplying utility power to midtown and lower Manhattan by Saturday evening, returning the island's data centers and citizens to some semblance of normalcy. In the past few days, data center managers have been forced to add fuel logistics to their list of responsibilities, as most Manhattan data centers have been subsisting on generator power. That should come to an end, for the most part, when utility power is restored. In a possibly worrying note, Verizon warned late on Nov. 1 that its services to business customers could be impacted due to lack of fuel."
New submitter Shotgun writes "I heard on the radio that there were some issues with voting machines in Greensboro, NC (my hometown), and the story said the machines just needed "recalibration". Which made me ask, "WTF? Why does a machine for choosing between one of a few choices need 'calibration'?" This story seems to explain the issue."
According to a (paywalled) report in the Wall Street Journal, Microsoft is experimenting with its own smartphone design. "Officials at some of Microsoft's parts suppliers, who declined to be named, said the Redmond, Wash.-based company is testing a smartphone design but isn't sure if a product will go into mass production." The article continues: "If Microsoft pushes ahead with its mobile phone, it would underscore how far Microsoft has moved away from its long-standing practice of making software and leaving decisions about design, features and marketing of the computing hardware to partners such as Hewlett-Packard or Samsung Electronics. ... As it does so, Microsoft pulls from a modified playbook of Apple—whose hardware-plus-software approach Microsoft officials long have scorned. ... Smartphones running Microsoft's two-year-old Windows Phone operating software for cellphones haven't sold well, and Microsoft may want to leave itself an option to test whether its own phone would spur sales."
cylonlover writes "The EU Commission's Community Research and Development Information Service (CORDIS) is working on a 'beaming' telepresence system that is designed to allow users to virtually experience being in a remote location by seeing, hearing and even feeling that location through the sensory inputs of a robot located there. That robot, in turn, would relay the user's speech and movements to the people at that location. Now, two of the CORDIS partners have put an interesting slant on the technology – they've used it to let people interact with rats."
derekmead writes "Batteries rule everything around us, which makes breakthroughs a big deal. A research team at Rice says they have produced a nice jump: by using a crushed silicon anode in a lithium-ion battery, they claim to have nearly tripled the energy density of current li-ion designs. Engineer Sibani Lisa Biswal and research scientist Madhuri Thakur reported in Nature's Scientific Reports (it has yet to be published online) that by taking porous silicon and crushing it, they were able to dramatically decrease the volume required for anode material. Silicon has long been looked at as an anode material because it holds up to ten times more lithium ions than graphite, which is most commonly used commercially. But it's previously been difficult to create a silicon anode with enough surface area to cycle reliably. Silicon also expands when it's lithiated, making it harder to produce a dense anode material. After previously testing a porous silicon 'sponge,' the duo decided to try crushing the sponges to make them more compact. The result is a new battery design that holds a charge of 1,000 milliamp hours per gram through 600 tested charge cycles of two hours charging, two hours discharging. According to the team, current graphite anodes can only handle 350 mAh/g."
Lucas123 writes "As anyone who's typed on a virtual keyboard — or yelled at a voice-control app like Siri — can attest, no current text input holds a candle to a traditional computer keyboard. From the reed switch keyboards of the early '70s to the buckling spring key mechanism that drove IBM's popular PC keyboards for years to ThinTouch technology that will have about half the travel of a MacBook Air's keys, the technology that drove data entry for decades isn't likely to go anywhere anytime soon. This article takes a look back on five decades of keyboard development and where it's likely to go in the future."
cylonlover writes "Having successfully negotiated the challenging regulatory slopes of the U.S. Bureau of Land Management, the U.S. Forest Service, the U.S. Department of Energy, and a host of Oregon state agencies, the Newberry Enhanced Geothermal Systems (EGS) demonstration project is in the process of creating a new geothermal reservoir in central Oregon. The core of the new reservoir is a two mile (3.2 km) deep well drilled about four miles (6.4 km) from the center of Newberry Volcano. The rock surrounding the wellbore reaches temperatures in the order of 600 F (300 C), and is nearly impermeable to water. That, however, is about to change. Newberry Volcano is one of the largest and youngest volcanoes in the United States. Having last erupted about 1,300 years ago, it consists of over 400 individual volcanic vents, which, when combined, form a broad mounded landform referred to as a shield volcano. The Newberry EGS Demonstration geothermal reservoir is being formed in the high-temperature, low-permeability deep lava of the volcano's northwest flank."
Zothecula writes "For people who are unable to walk under their own power, exoskeletons offer what is perhaps the next-best thing. The devices not only let their users stand, but they also move their legs for them, allowing them to walk. While groups such as Berkeley Bionics, NASA, Rex Bionics, and ReWalk are all working on systems, Nashville's Vanderbilt University has just announced the development of its own exoskeleton. It is claimed to offer some important advantages over its competitors."
