Open-bus technologies, while perhaps costing more initially, says Murray Death, InterlinkBT president, more than make up for that in labor savings. "Customers have reported savings of up to 65% on installation costs." And these benefits extend to engineering. For example, documentation and layout complexity are greatly reduced. "Complex wiring documentation is virtually eliminated," he notes, and during set-up, bus components can be mounted as needed during installation.
With less wiring inherent in multiplexed systems, set-up time is shorter, so processes go on-line quicker. There is less chance for wiring mistakes, debugging is less time-consuming, and keyed connectors facilitate "plug and program" versatility. A breadth of connector styles cuts installation time and reduces chances of wiring errors. Once a bus system is up-and-running, diagnostics pinpoint a problem before it becomes critical. And again, with plug-in adaptability, a malfunctioning component can be removed and a new one installed quickly. Such time savings give a higher return on investment.
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.
