  2. Warnier/Orr diagram - Wikipedia

    en.wikipedia.org/wiki/Warnier/Orr_diagram

    They were initially developed 1976, [1] in France by Jean-Dominique Warnier [2] and in the United States by Kenneth Orr [3] on the foundation of Boolean algebra. [4] This method aids the design of program structures by identifying the output and processing results and then working backwards to determine the steps and combinations of input ...

    Free-body diagram of a U-channel synchronous linear motor. The view is perpendicular to the channel axis. The two coils at centre are mechanically connected, and are energized in "quadrature" (meaning a phase difference of 90° (π/2 radians) between the flux of the magnets and the flux of the coils).
