    • An integrator and averager for use with graphs or recorder charts is described. In use the graph is placed on a tablet and a stylus is used to follow the curve. The tablet has an upper conductive sheet and a lower layer which may be a series of parallel conductors or a condutive layer. Voltage is normally applied across the lower layer in the direction of the independent variable and sensed from the upper sheet. An increment detector causes voltage to be applied across the lower layer instead, for a predetermined interval, in the direction of the dependent layer, each time an increment of the independent variable is detected. An integrator is charged during the intervals and its output is indicative of the area under the graph. By automatically dividing the interval of the independent variable over which the graph was traced, the average value is obtained.
    • 描述了用于图形或记录图表的集成商和平均机。 在使用中,图表放在平板电脑上,并使用触控笔来跟随曲线。 片剂具有上导电片和下层,其可以是一系列平行导体或调节层。 电压通常沿着独立变量的方向跨越下层施加并且从上部片材感测。 增量检测器在每次检测到独立变量的增量时,使得电压跨越下层代替在依赖层的方向上延伸预定间隔。 在间隔期间对积分器进行充电,其输出表示图表下的面积。 通过自动划分跟踪图形的自变量的间隔,获得平均值。
