    • Means for extending the ability of an analog or hybrid computer which allow solution of problems, and various predetermined displays of the solutions as functions of additional independent variables of the operator''s choice. The means include a staircase generator for varying an independent variable for each computation of the problem and peak and level sensing circuits so that a three-dimensional surface representing the solution to the problem may be displayed as a family of curves, as an isometric projection, as a cross-plot of a time history, as a cross-plot of positive or negative peaks, and as a conformal map.
    • 用于扩展允许解决问题的模拟或混合计算机的能力以及解决方案的各种预定显示作为操作者选择的附加独立变量的函数的手段。 该装置包括用于为问题的每次计算改变独立变量的阶梯发生器以及峰值和水平感测电路,使得表示该问题的解决方案的三维表面可以作为等距投影而显示为一系列曲线, 作为时间历史的交叉图,作为正或负峰的交叉图,以及作为保形图。
