Despite being commercially available, drones can be a real threat. They can barge into no-fly zones, engage in mid-air crashes, reconnaissance missions, or even conduct deadly air-strikes. The risk of such attacks never wears off but in order protect its critical installations against rogue UAVs, United States military is working on some lethal counter-drone weapons. The service, in collaboration with defense manufacturer Raytheon, has produced two Counter-Unmanned Aerial Systems (UAV) -- one that uses high power microwave (HPM) to disable the target and other that deploys a high energy laser (HEL) to disintegrate it. The two systems were put to test in a recent Maneuver Fire Integrated Experiment and were able to take out as many as 45 different drones out of the sky, along with a few stationary mortal projectiles, Popular Mechanics reported.
In a bid to modernize battlefield resources, the Chinese Army has started trialing unmanned tanks, according to a new report from state-run publication Global Times. The upgraded military vehicles are currently being tested with a distant manned console, much like remotely operated drones. However, the People's Liberation Army Ground Force, aka PLAGF, also plans to integrate them with artificial intelligence, in order to make them nearly self-operable. A short video from CCTV, a prominent state television broadcaster in the People's Republic of China, recently appeared on the internet showcasing one of the unmanned vehicles being tested. The clip features a modified version of a dated Type 59 tank moving forward and backward like a remote-controlled car and a distant Chinese Army official manning its control-box a few meters away.
The US Army is working on a new mine detector that allows soldiers to see as well as analyze the size of an explosive hidden underground. The new device uses real-time spatial location tracking and a range of sensors to produce an image of the buried object, be it an active IED or some unexploded artillery shell. As seen in the video, the tech creates a colored map on a tablet as and when the surface is scanned by the device. The area highlighted in orange roughly represents the scale or the metallic object or a potential risk-zone, while other colors represent the safer areas. "You can immediately see the shape of the object and roughly its size," Christopher Marshall, a scientist in the Countermine Division of the Night Vision and Electronic Sensors Directorate, said in a statement.
The world is full of connected devices – and more are coming. In 2017, there were an estimated 8.4 billion internet-enabled thermostats, cameras, streetlights and other electronics. By 2020 that number could exceed 20 billion, and by 2030 there could be 500 billion or more. Because they'll all be online all the time, each of those devices – whether a voice-recognition personal assistant or a pay-by-phone parking meter or a temperature sensor deep in an industrial robot – will be vulnerable to a cyberattack and could even be part of one. Today, many "smart" internet-connected devices are made by large companies with well-known brand names, like Google, Apple, Microsoft and Samsung, which have both the technological systems and the marketing incentive to fix any security problems quickly.
