    • Computer-implemented systems and methods for performing forecast scoring based upon time series data that is indicative of a data generation activity occurring over a period of time. One or more data stores store historical data and future data. The historical data includes historical exogenous inputs. The future data includes future exogenous inputs. A dynamic statistical model receives the historical data and future data that are stored in the one or more data stores. The dynamic statistical model is to provide forecast scoring based upon the historical exogenous inputs and the future exogenous inputs. An optimizer having an objective function iteratively varies the future data, so that forecasts associated with the varying future data values are generated by the dynamic statistical model for evaluation by the objective function.

    • A magnetic position sensor has a stator (16′, 36, 52) formed of magnetic material and a pair of magnets (14a, 14b; 34a, 34b; 54a, 54b; 64a, 64b) rotatably mounted about the stator and movable between opposite angular extremities and spaced from the stator by a primary cylindrical air gap (5). A secondary air gap (4) is formed in a stationary member at a location at which the magnetic field varies with the angular position of the magnets. A first Hall Effect sensor (18) is disposed in the secondary air gap to measure the magnetic field there-across as an indication of the angular position of the magnets. A second reference sensor (22) is provided to detect the magnetic decay of the magnets. The second sensor can be a Hall Effect sensor disposed at a location at which the magnetic field is relatively constant, independent of the angular position of the magnets. The reference sensor output can be used as a diagnostic indicator or as a correction for the first sensor output.
    • 磁性位置传感器具有由磁性材料形成的定子(16',36,52)和一对磁体(14a,14b; 34a,34b; 54a,54b; 64a,64b) 安装在定子周围并可在相对的角度端部之间移动并且通过主圆柱形气隙(5)与定子间隔开。 在磁场随着磁体的角位置变化的位置处在静止构件中形成二次气隙(​​4)。 第二霍尔效应传感器(18)设置在二次气隙中以测量其中的磁场,作为磁体的角位置的指示。 提供第二参考传感器(22)以检测磁体的磁衰减。 第二传感器可以是设置在磁场相对恒定的位置处的霍尔效应传感器,与磁体的角位置无关。 参考传感器输出可用作诊断指示器或作为第一传感器输出的校正。
