The SD-15900 two-speed synchro or resolver combiner works in conjunction with any two synchro- or resolver-to-digital converters. The SD-15900 device combines the digital information from the coarse S/D channel and the digital information from the fine S/D channel, resulting in up to 22 bits of angular data. The combiner and S/D converters can be powered by a single 5V dc power supply. The small size of the components and the high accuracy obtainable with two-speed combinations make the combiner targeted for use in high-performance military and industrial position-control systems.

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.
