ELECTRONICS/SENSORS: The second generation KEYENCE GT2 “All-in-One” contact digital sensor, adopts the world’s first scale-shot system to provide the highest precision in its class (0.1μ resolution, 1.0μ accuracy). Maintaining the “No Error” feature from its predecessor, no data will be lost due to rapid spindle movement during production line and other high-speed applications. All measurement is performed in the compact GT amplifier requiring no PLC or external data processing.GT2 sensors are tough and rugged, and the cable’s IP67 water-resistant enclosure rating helps prevent or reduce swap outs in select harsh environments. The sensor head cable uses a flexible robot cable that can withstand continuous bending up to 6 million times at a radius of 50 mm (1.97 inch) and can be cut anywhere to length. Linear ball bearings covered by a strong rubber encase the spindle to ensure a long service life by eliminating wear and abrasion damage. Detecting durability extends up to 20 million times.
The analog I/O card used with conventional sensors is not required for the GT2, which further reduces labor time, and total cost equipment status can be quickly checked by looking at the bar indicator that displays green when the data is within its limits and red when the values are out of spec.
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.
