  • IVI Extends Its Reach

    D. Chiej

    págs. 6-7

    

  • Monitoring Your Equipment SmartSignal software may just outperform the standard threshold approach to anomaly detection. The software's detection engine can monitor an aggregate of correlated sensors from an instrumented system and detect subtle deviations from normal operation

    D. Brochu, A. Wilks

    págs. 18-29

    

  • Diamagnetic Levitation: The Invisible Force Until recently a laboratory curiosity, diamagnetism has entered the commercial world as part of a hybrid levitation system in which a diamagnetic force provides the necessary control stability and permanent magnets supply the lift

    R. Schmidt

    págs. 30-41

    

  • The Next Generation of Position Sensing Technology, Part 1: Theory and Design NCAPS is a new noncontact angular position sensor featuring an inductive attenuating coupler that measures phase shift rather than the magnitude of the coupling signal. The original implementations were for a 360^o rotary sensor, but the basic concept has also evolved into a linear version

    págs. 42-55

    

  • Trends in Automation PC-based lean control architecture is rapidly gaining popularity-and improving productivity, efficiency, and reliability along the way
