Ground troops often want to watch for threats from fairly limited areas, but ships at sea need to monitor huge expanses for long periods. The U.S. Naval Research Lab. is exploring ways to continuously monitor large spaces at fairly low costs. Goodrich Corp. has been given a contract to provide CA-247 wide-area airborne persistent surveillance sensors that help monitor oceans or provide situational awareness to ground troops in urban environments. The CA-247 sensor's infrared optics are stabilized for image clarity, also offering software that helps human observers pinpoint potential threats.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
