This new series of RMS current transducers offer accuracy over a 20Hz-2KHz range. Available in 14 current ranges from 2A to 250A, they have an accuracy of 0.25 percent over a temperature range of -40 to 85C (-40 to 185F). They also have a wide voltage power range from 12V to 32V, and a current signal from 4mAdc to 20mAdc. They protect against reverse polarity and overload currents of up to 500A, plus a load resistance range from 0 to 300. They have an epoxy coating on the internal circuitry for insulation and protection from moisture and contaminants. They come built into a molded plastic, 94V-O flammability-rated case. Storage temperature is -55 to 125C (-67 to 257F)They also come with a five-terminal barrier and a 0.75-inch pass-through hole. A six-pin connector and nine-pin D-Sub connector are also available.
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.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
