Quadcopter Guided By Thought — Accurately
ananyo writes "A toy quadcopter can be steered through an obstacle course by thought alone. The aircraft's pilot operates it remotely using a cap of electrodes to detect brainwaves that are translated into commands. Ultimately, the developers of the mind-controlled copter hope to adapt their technology for directing artificial robotic limbs and other medical devices." From the paper (PDF) abstract: "... we report a novel experiment of BCI controlling a robotic quadcopter in three-dimensional (3D) physical space using noninvasive scalp electroencephalogram (EEG) in human subjects. We then quantify the performance of this system using metrics suitable for asynchronous BCI. Lastly, we examine the impact that the operation of a real world device has on subjects’ control in comparison to a 2D virtual cursor task. Approach. ... Individual subjects were able to accurately acquire up to 90.5% of all valid targets presented while traveling at an average straight-line speed of 0.69 m s^(1)." This ...
Ex-Marine Detained Under Operation Vigilant Eagle For His Political Views Sues
stry_cat writes "You may remember the story of Brandon Raub, who was detained without due process over some Facebook posts he made. Now with the help of the Rutherford Institute, he is suing his captors. According to his complaint [PDF], his detention was part of a federal government program code-named 'Operation Vigilant Eagle,' which monitors military veterans with certain political views."
Death Knell For Righthaven In 9th Circuit Decision
An anonymous reader writes with this snippet from Ars Technica: "Righthaven, the Las Vegas operation that sought to turn newspaper article copyright lawsuits into a business model, can now slap a date on its death certificate: May 9, 2013. This morning, the US Court of Appeals for the Ninth Circuit ruled on the two Righthaven appeals that could have given the firm a final glimmer of hope—and the court told Righthaven to take a hike (PDF)."
Space Junk 'Cleaning' Missions Urgently Needed
Following a conference on space debris, the European Space Agency has warned that the amount of space junk floating around in orbit is a problem that needs to be dealt with 'urgently.' They are calling for a number of test missions to examine different methods of controlling or removing the debris. "Our understanding of the growing space debris problem can be compared with our understanding of the need to address Earth’s changing climate some 20 years ago," said Heiner Klinkrad, head of the agency's Space Debris office. A couple years ago we discussed an idea for de-orbiting space junk by hitting it with a laser to change its momentum. An Australian company has now received funding from NASA and the Australian government to try just that. "We've been developing tracking systems using lasers for some years, so we can actually track very small objects with a laser rangefinder to very high accuracy. ... If you allow that velocity to change over a period of perhaps 24 hours, then you can get ...
Florida House Passes Bill To Ban "Internet Cafes"
squiggleslash writes "Concerned about their use as fronts for gambling operations, the Florida legislature passed a law banning Internet cafes. The law appears to be a reaction in part to the recent stepping down of Lt. Gov. Jennifer Carroll, embroiled in a scandal involving a company that operates Internet Cafes. More ordinary cafes with Wi-fi, where you supply your own computer (such as Starbucks), are not affected by the ban." The nomenclature here is confusing; the bill (PDF) (summary) is clearly aimed only at "cafes" that are essentially gambling venues; an Internet cafe wouldn't violate the proposed rule merely by providing computers. Whatever you think of prohibitions on gambling among consenting adults, the bill itself is sort of amusing for its very specific loopholes for bingo and "reverse vending machines."
