Lockheed Martin Stalker drone stays airborne 48 hours using laser power, all-seeing eye gets literal (video)
Aerial drone designers have been pushing hard to get devices that can stay airborne for days. After all, what's the point of having an observer that routinely lets its guard down? Lockheed Martin must have this question forever etched in its collective mind, as it just completed tests of a modified Stalker drone that was continually charged by laser power beamed from a ground-based source. The LaserMotive-built test was admittedly conducted in a wind tunnel, not a wind-swept battlefield, but it kept the drone aloft for more than 48 hours and was so efficient that it might even have gone indefinitely, if it weren't for staff intentionally bringing the trial to a halt. The true test is coming next, when Lockheed Martin and LaserMotive fly the drone on laser power outdoors. Should the Stalker sail the friendly skies for long enough, it could help usher in an era of UAVs that can spot intruders at all hours -- a little too close to the aircraft's name for comfort, perhaps, but potentially vital for Special Operations troops that might not have to put themselves in danger. You can check the underpinnings of both the laser power system and the Stalker in videos after the break.
Military deploys VR NeuroTracker game to train special ops forces (video)
We've seen virtual reality used to simulate the experience of being in space, to train engineers and even to help patients regain mobility, so it's no surprise that the military is recognizing VR's potential, too. The US Special Operations Command recently announced that it will employ NeuroTracker -- a system currently used to train athletes in the NFL and NHL -- to assess and improve commandos' response times and perceptive capabilities. The VR setup tasks commandos with following the movements of four different balls projected on a 3D screen, the catch being that four "decoy" objects are also bouncing around. NeuroTracker assesses how well an individual can keep track of the designated targets, and also helps determine how he or she would be able to predict trajectories in the field. Once a user has completed the first game, several variations come into play, including a version that speeds up the balls' movements and one that pits two players against each other. CogniSens, the company behind NeuroTracker, says the game develops perceptive abilities just like a workout develops muscles; there's even a high-intensity gameplay option that combines the mental challenge with physical conditioning exercises.
