Designed for applications requiring high flow in an extremely compact package, especially in the medical, automotive, and business equipment markets, the new durable, oil-less Model 1420 pump achieves higher flows than conventional standard diaphragm pumps of the same physical size. The pump measures 3.41 inches long × 1.16 inches wide × 2.96 inches high, and weighs .485 lbs. Flow is rated at 6.0 to 11.0 lpm, when the heads are in parallel configuration, and up to 5.5 lpm in series configuration. The maximum pressure rating is 1 bar, and the maximum vacuum rating is 23 inches Hg. The Model 1420 pump is available in both 12 and 24V dc versions and incorporates long-life EPDM (ethylene-propylene rubber) diaphragms and valves.
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.
