MOTION CONTROL: The DEC Module 24/2 from maxon motor is a digital 1-quadrant amplifier with speed controller for brushless EC motors with Hall Sensors up to 48W and a surface area measuring less than 5 cm2. The DEC module 24/2 is a miniaturized, powerful plug-in module that can be seamlessly integrated into most complex applications with little effort. The wide supply voltage range of 8-24V dc (alternatively 5V dc) and a continuous output current of 2A, permits flexible multifunctional operation at a high efficiency factor. The amplifier offers a large number of inputs and outputs (such as enabling, speed ranges, direction of rotation presetting, current limiting, operational status) and comprehensive protection features (such as over-current, undervoltage/overvoltage, thermal overload, blockage and short circuit). The amplifier is also designed for a maximum motor speed of 80,000 rpm. Two connector arrays arranged in a 2.54 mm (0.1 inch) pattern support easy connectivity and integration into the OEM-side motherboard.
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.
Biomedical engineering is one of the fastest growing engineering fields; from medical devices and pharmaceuticals to more cutting-edge areas like tissue, genetic, and neural engineering, US biomedical engineers (BMEs) boast salaries nearly double the annual mean wage and have faster than average job growth.
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.
