In today’s world, one of the things that’s more sought after than portability is a way to find mobile products. Trolley Scan (Pty) Ltd. developed what it calls RFID-radar, which measures a signal’s travel distance to identify and locate many transponders in a large reading zone. The South African developer feels the technology can be used in applications as diverse as tracking shopping carts, called trolleys in many regions, as well as retirement home patients and art in museums. Microchip Technology’s dsPIC digital controller performs 10,000 measurements per sec, letting the system handle 50 targets at once with a measuring accuracy of 0.5m at distances of up to 100m.
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.
