VertiKUL Drone "Delivers" on Both Hovering and Forward Flight

Zothecula Zothecula writes  |  5 hours ago

Zothecula (1870348) writes "When something is sent to you by airmail, it travels in a fast and relatively fuel-efficient fixed-wing aircraft, not a fuel-guzzling helicopter. Nonetheless, when we hear about the possibility of drones being used to deliver items within cities, multirotor-style aircraft are almost always what's proposed – while they're good at maneuvering in urban spaces, they're essentially just little unmanned helicopters. With that in mind, a group of three engineering students from Belgium's KU Leuven (Katholieke Universiteit Leuven) have created a prototype delivery drone known as VertiKUL, which combines the best features of both types of aircraft."

Robotic Vehicles Team Up on First Fully Autonomous Mission Demonstration

Zothecula Zothecula writes  |  yesterday

Zothecula (1870348) writes "While aircraft such as the X-47B are paving the way for unmanned aircraft filling combat roles, autonomous aircraft are also being developed to tackle more mundane – but still dangerous – military operations. To this end, the first fully autonomous resupply, reconnaissance, surveillance and target-acquisition demonstration using the Squad Mission Support System (SMSS) unmanned ground vehicle, K-MAX unmanned helicopter and Gyrocam optical sensor was recently conducted at Fort Benning, Georgia."

Software Combines Thousands of Online Images Into One That Represents Them All

Zothecula Zothecula writes  |  2 days ago

Zothecula (1870348) writes "If you're trying to find out what the common features of tabby cats are, a Google image search will likely yield more results than you'd ever have the time or inclination to look over. New software created at the University of California, Berkeley, however, is designed to make such quests considerably easier. Known as AverageExplorer, it searches out thousands of images of a given subject, then amalgamates them into one composite "average" image."

Over 1,000 Robots Swarm Together in Harvard Lab

Zothecula Zothecula writes  |  4 days ago

Zothecula (1870348) writes "Ants, schooling fish and flocking birds all have something in common – they can achieve things by working together that they could never do on their own. With that in mind, researchers are now looking into ways of allowing "swarms" of communicating robots to accomplish tasks that are difficult or even impossible for single robots. Harvard University recently performed an unprecedented demonstration of that behavior, in which a batch of over 1,000 tiny Kilobots arranged themselves into a variety of pre-assigned two-dimensional shapes."

Involuntary Eye Movement May Provide Definitive Diagnosis of ADHD

Zothecula Zothecula writes  |  5 days ago

Zothecula (1870348) writes "If a child who's simply very active is mistakenly diagnosed with Attention Deficit Hyperactivity Disorder (ADHD), they can end up on pharmaceuticals such as Ritalin unnecessarily. The problem is, it can be quite difficult to determine if someone actually has ADHD, and misdiagnoses are common. Now, however, researchers from Tel Aviv University have announced that analyzing a patient's eye movements may be the key."

Mobile Phones Could Be Charged Using Sound

Zothecula Zothecula writes  |  about a week ago

Zothecula (1870348) writes "Four years ago, we first heard about how Korean scientist had proposed using sound to charge mobile phones. They explained that it could be done via a piezoelectric effect, in which zinc oxide nanowires converted sound-caused vibrations into electricity. At the time, the researchers couldn't generate enough of a current to actually charge a phone. Now, however, scientists from Nokia and Queen Mary University of London (QMUL) have succeeded in doing so."

Photo Editing Tool Shows Viewers What the Camera Couldn't See

Zothecula Zothecula writes  |  about two weeks ago

Zothecula (1870348) writes "Many people are already annoyed when characters on TV cop shows "zoom in and enhance" on a photo, to reveal a level of detail that could never really have been captured by the camera. Thanks to software developed at Carnegie Mellon University, however, it's now possible to actually turn objects in a photo around ... seemingly revealing sides of them that were facing away from the camera when the picture was taken."

Perlan ll Project Aims to Fly a Glider to the Edge of Space

Zothecula Zothecula writes  |  about three weeks ago

Zothecula (1870348) writes "In an ambitious attempt to break every wing-borne sustained flight height record for a manned aircraft, the Perlan ll project intends to construct and fly a glider higher than any sailplane has gone before. Riding on the colossal stratospheric air waves generated over mountains, the team plans to fly their craft to more than 90,000 ft (27,000 m), which will shatter their own existing glider altitude record of 50,671 ft (15,400 m) set by Perlan l in 2008."

Vision-Correcting Display Lets Users Ditch Their Reading Glasses

Zothecula Zothecula writes  |  about three weeks 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  |  about three weeks ago

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  |  about three weeks 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 month 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 month 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 month 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."
