BEI Industrial Encoders has rolled out a wireless interface system for incremental encoders. Called SwiftComm, the system includes a transmitter-receiver pair that communicates using a point-to-point, frequency-hopping 2.4 GHz RF protocol. The proprietary protocol includes a broad security code range, data encryption, handshaking, interference recovery and error checking. SwiftComm is intended for use in applications such as factory automation, printing, crane, hoist and mining equipment that would require a long cable run for conventional encoders.

VFS 60 Motor Feedback Systems
The VFS 60 Motor Feedback Systems from SICK STEGMANN Inc. feature a nickel code disc designed to withstand harsh industrial environments and ac induction motor applications that can give models with glass code discs trouble. Packaged in an industry-standard 60 mm housing, VFS 60 encoders mount to ac induction motors and deliver up to 10,000 ppr at operating temperatures up to 100C — versus 70C for many glass- or plastic-disc models. They also offer shock resistance to 70 g/6 ms and vibration resistance to 30 g up to 2,000 Hz. As an option, the encoders can be purchased with a user-programmable PPR, zero pulse set and type of electrical interface.
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.
