Replacing the coils of conventional resolvers, encoders, and LVDTs with a silicon chip allows position measurement miniaturization at maintained or better performance. A micro-coil matrix, integrated interface circuit, package, and external scale in anymetallic material make up the sensor.
To work, one of the micro-coils generates a field, modulated by the metallic scale. This amplitude-modulated field imparts an induced voltage in the detector micro-coils. Interface circuitry processes the AM signal to deduce position, speed, and direction of movement. Output can be analog, digital, or any other format required by the application.

In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
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.
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.
