These connectors can go through about 10,000 mate/unmate cycles without a loss in performance, can be mated and unmated in less than two seconds, and offer less crosstalk with the contact in the female connector mating directly with the PCB on the plug half. The connectors use 34-way high-density contact modules, and a simple cam and bearing mechanism allows all the contacts to be mated at once with a quarter turn of the knob shaft. Mating torque is 2 N.m, and shock and vibration performance is to MIL-STD-202F. They come in 136, 204, 272, and 408 configurations. They have a maximum contact resistance of 30m and a rated current of 0.5A. Metal shells and grounding springs offer plenty of EMI/RFI protection. They cost about $0.30/IO depending on volume and configuration.
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.
