    • Rules, applied to deny authorization of likely fraudulent transactions, are derived from a modified Patient Rule Induction Method algorithm that uses a target variable and a data set of past transactions each associated with a plurality of input variables and a hyper-rectangle enclosing a multi-dimensional space defined by a representation of the input variable values as points within the multi-dimensional space. While a count of the points within the hyper-rectangle is greater than a minimum support parameter, a first plurality of points proximal to edges of the hyper-rectangle are removed, where each such removing maximizes a mean value of the target variable, and then, while the mean value remains maximized, a second plurality of points proximal to the edges is added, where each adding maximizes or maintains the mean value. The hyper-rectangle is bounded within a minimum bounding box that defines the rules.

    • Dynamic range is widened in a display device with a photosensor that can read an image due to having a photodetection element inside a pixel thereof. A sensor driving circuit switches ON a reset signal (RST) that is supplied via reset signal bus line, and after a predetermined time has elapsed, switches ON a readout signal (RWS) that is supplied via readout signal bus line. Thus, in the photosensor, from which a photosensor signal is output in accordance with an amount of light received by the photosensor in the predetermined time, the capacitance of a capacitor provided in the photosensor is made variable from when the reset signal (RST) is supplied to the photosensor until when the predetermined time has elapsed.
    • 在具有光传感器的显示装置中,由于在像素内部具有光电检测元件而能够读取图像,动态范围变宽。 传感器驱动电路接通通过复位信号总线提供的复位信号(RST),在经过预定时间之后,接通通过读出信号总线提供的读出信号(RWS)。 因此,在光电传感器中,根据光电传感器在预定时间内接收的光量输出光电传感器信号,使得设置在光传感器中的电容器的电容从复位信号(RST)为 提供给光传感器,直到经过了预定时间。
