Capitalizing on the ability of human bones to conduct sound underwater, France Telecom R&D, in partnership with the French communications company Amphicom, has invented what it claims is a "world first." Comprising a buoy fitted with a GSM phone relay, and an underwater terminal, the company's system allows telephone communication with an undersea diver. The terminal, hard wired to the buoy, is equipped with a telephone-like dial pad and special mouthpiece. A buzzer and flashing light alert the diver to incoming calls. Sound waves from the surface transit through the system to the mouthpiece. When the diver bites down on the mouthpiece, the vibrations propagate to the ear via the skull, which acts as a resonance chamber. Conversely, the diver can talk back in half duplex mode. Presently under test by archeologists excavating the presumed site of ancient Egypt's Alexandria lighthouse, the underwater communication system is scheduled for commercialization by the end of this year. France Telecom, meanwhile, is looking at ways to eliminate the wire link between buoy and submerged terminal. Call Manuel Lesaicherre at +33 1 44 44 93 93 or e-mail manuel. email@example.com.
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.
