Vision-Correcting Display Lets Users Ditch Their Reading Glasses

Zothecula Zothecula writes  |  4 hours ago

Zothecula (1870348) writes "We've seen a number of glasses-free 3D technologies in recent years, most famously in Nintendo's 3DS, but now researchers at the University of California at Berkeley and MIT have created a prototype device that allows those with vision problems to ditch their eyeglasses and contact lenses when viewing regular 2D computer displays by compensating for the viewer's visual impairment."

Silent Power PC Ditches the Fan for a "Cool" Copper Afro

Zothecula Zothecula writes  |  yesterday

Zothecula (1870348) writes "The Silent Power PC is claimed to be the first high-end PC able to ditch noisy electric fans in favor of fully passive cooling. In place of a conventional fan, the unit uses an open-air metal foam heatsink that boasts an enormous surface area thanks to the open-weave filaments of copper of which it is composed. The Silent Power creators claim that the circulation of air through the foam is so efficient in dissipating heat that the exterior surface temperature never rises above 50 C (122 F) in normal use."

Fove Head Mounted Display Expands Possibilities With Eye-Tracking Technology

Zothecula Zothecula writes  |  3 days ago

Zothecula (1870348) writes "Back in 2011, Google filed a patent for an unlock system for Google Glass that would use eye-tracking technology. Tokyo-based startup Fove believes the combination of a head mounted display (HMD) and eye-tracking technology has far wider applications and is working on just such a device aimed at the consumer market. Microsoft apparently agrees, having accepted the company into its Ventures Accelerator in London earlier this month."

Fly-Inspired Tech Could Find Use in Better Hearing Aids

Zothecula Zothecula writes  |  about a week ago

Zothecula (1870348) writes "When it comes to animals with good hearing, flies might not be the first one you'd think of. The Ormia ochracea fly, however, has a unique hearing mechanism that allows it to precisely determine the location of a cricket based on its chirps ... it then deposits its larvae on the cricket, which ultimately consume the poor insect. Scientists at the University of Texas Austin have now duplicated that mechanism, with hopes that it could find use in applications such as next-generation hearing aids."

Cyberith's Virtualizer Brings Running, Jumping... and Sitting to Virtual Reality

Zothecula Zothecula writes  |  about a week ago

Zothecula (1870348) writes "In recent years, we've seen a number of virtual reality (VR) devices targeted at bringing more immersive gaming to the home while also adding locomotion to the mix. Joining the charge is the Virtualizer from Austrian-based company Cyberith. The rig features an omni-directional treadmill, which is nothing new, but in addition to letting gamers walk and run on the spot, it also lets them rotate, jump, crouch, kneel and even sit down, with these motions matched in game by their virtual selves."

HARKEN System Monitors Drivers' Fatigue Levels Via Their Seat

Zothecula Zothecula writes  |  about a week ago

Zothecula (1870348) writes "It was just last week that we heard about how researchers from Nottingham Trent University are looking at embedding heart rate sensors in car seats, to detect when drivers are nodding off. Well, it turns out that they're not the only ones. A consortium of European companies and institutes is developing a similar system known as HARKEN, which uses seat-located sensors to monitor both the driver's heart rate and their rate of respiration."

New Technique Could Boost Internet Speeds Tenfold

Zothecula Zothecula writes  |  about two weeks ago

Zothecula (1870348) writes "Researchers at Aalborg University, MIT and Caltech have developed a new mathematically-based technique that can boost internet data speeds by up to 10 times, by making the nodes of a network much smarter and more adaptable. The advance also vastly improves the security of data transmissions, and could find its way into 5G mobile networks, satellite communications and the Internet of Things."

Gene Therapy Converts Heart Cells Into "Biological Pacemakers"

Zothecula Zothecula writes  |  about two weeks ago

Zothecula (1870348) writes "Pacemakers serve an invaluable purpose, by electrically stimulating a recipient's heart in order to keep it beating at a steady rate. The implantation of a pacemaker is a major surgical procedure, however, plus its presence in the body can lead to complications such as infections. Now, for the first time, scientists have instead injected genes into the defective hearts of pigs, converting unspecialized heart cells into "biological pacemakers.""

US Marines Demonstrate Ultra Heavy-lift Amphibious Connector Prototype

Zothecula Zothecula writes  |  about two weeks ago

Zothecula (1870348) writes "In a recent demonstration carried out during RIMPAC 2014, the US Marines displayed and tested a fully-functional, half-scale prototype of its new amphibious transport vehicle. In its proposed full-size version the Ultra Heavy-Lift Amphibious Connecter (UHAC) concept is designed to power across the water with a payload of nearly 200 tons (180 tonnes) at up to 20 knots (23 mph/37 km/h) and be capable of driving up on to the shore and over the top of obstructions up to 10 ft (3 m) high."

Drones May Find Use as Smart Photographic Light Sources

Zothecula Zothecula writes  |  about two weeks ago

Zothecula (1870348) writes "As any professional photographer knows, setting up lights can be a hassle. This is often the case in the studio, but especially when shooting on location. Before too long, however, it may be possible to use hovering autonomous drones as light sources. In fact, that's just what a team from MIT and Cornell University has already done. Their system not only does away with light stands, but the light-equipped aircraft automatically moves to compensate for movements of the model or photographer."

Borospherene Bounces Into Buckyball Family

Zothecula Zothecula writes  |  about two weeks ago

Zothecula (1870348) writes "Buckyballs (or Buckminsterfullerene), the soccer ball-like structures of 60 carbon atoms, have a new playmate. Previously only theorized, researchers from Brown University in the US and Shanxi and Tsinghua Universities in China have been the first to experimentally observe a boron "buckyball.""

"Nano-Pixels" Hold Huge Potential For Flexible, Low-Power, High-Res Screens

Zothecula Zothecula writes  |  about three weeks ago

Zothecula (1870348) writes "The Retina displays featured on Apple's iPhone 4 and 5 models pack a pixel density of 326 ppi, with individual pixels measuring 78 micrometers. That might seem plenty good enough given the average human eye is unable to differentiate between the individual pixels, but scientists in the UK have now developed technology that could lead to extremely high-resolution displays that put such pixel densities to shame."

Sand-Based Anode Triples Lithium-Ion Battery Performance

Zothecula Zothecula writes  |  about three weeks ago

Zothecula (1870348) writes "Conventional lithium-ion batteries rely on anodes made of graphite, but it is widely believed that the performance of this material has reached its zenith, prompting researchers to look at possible replacements. Much of the focus has been on nanoscale silicon, but it remains difficult to produce in large quantities and usually degrades quickly. Researchers at the University of California, Riverside have overcome these problems by developing a lithium-ion battery anode using sand."

Student-Designed Device Reduces Gas Lawnmower Air Pollution By Over 90%

Zothecula Zothecula writes  |  about three weeks ago

Zothecula (1870348) writes "Gas-powered lawnmowers are notorious polluters. According to the US Environmental Protection Agency, running a new gas mower for one hour produces as much air pollution as would be generated by 11 typical automobiles being driven for the same amount of time. Switching to an electric or reel mower is certainly one option, but for those applications where it's gotta be gasoline, a team of engineering students from the University of California, Riverside are developing another: an attachment that they claim reduces noxious emissions by over 90 percent."

Airbus Patents Windowless Cockpit That Would Increase Pilots' Field of View

Zothecula Zothecula writes  |  about three weeks ago

Zothecula (1870348) writes "Imagine showing up at the airport to catch your flight, looking at your plane, and noticing that instead of windows, the cockpit is now a smooth cone of aluminum. It may seem like the worst case of quality control in history, but Airbus argues that this could be the airliner of the future. In a new US patent application, the EU aircraft consortium outlines a new cockpit design that replaces the traditional cockpit with one that uses 3D view screens instead of conventional windows."

Polymer-Based Graphene Substitute is Easy to Mass-Produce

Zothecula Zothecula writes  |  about a month ago

Zothecula (1870348) writes "For all the attention graphene gets thanks to its impressive list of properties, how many of us have actually encountered it in anything other than its raw graphite form? Show of hands. No-one? That's because it is still difficult to mass-produce without introducing defects. Now a team at the Korea Institute of Science and Technology (KIST) has developed a graphene substitute from plastic that offers the benefits of graphene for use in solar cells and semiconductor chips, but is easy to mass-produce."
