SENSORS:Kavlico recently introduced a rugged, aerospace-grade differential pressure (DP) sensor for monitoring pressure drop across a turbine engine style inlet air filter, also known as an inlet barrier filter. The DP sensor monitors filter health by detecting increases in pressure across the filter element. The DP sensor incorporates a piezo-resistive sense element and is available in pressure ranges of 0-1, ±1, ±5 and ±10 PSID, with other options available. Other features include an operating temperature range of -40 to 125C with a storage temperature of -55 to 150C, an accuracy of ±1.5 percent of full scale over the operating temperature and an operating voltage of 5 to 15V dc. The lightweight device (<6.5 oz) is rugged by design and has a housing constructed of an anodized aluminum with an MTBF of 300,000 hours at normal operating temperature. The DP sensor typically provides an output of 50 mV at 10V dc excitation.
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.
