    • A lock-in amplifier with an additional phase-sensitive detector is provided. A measurement signal is mixed in a multiplicative fashion with a reference signal, which is phase-shifted by 90 degrees, for a modulation frequency. In order to reliably filter out interference signal portions in a widest possible dynamic range and, at the same time, minimize unavoidable influence on the useful signal portion, a control device is connected downstream of the additional phase-sensitive detector. The control device determines a control variable corresponding to the strength of the interference signal from the measurement signal mixed with the reference signal phase shifted by 90 degrees and uses the control variable to change the integration duration of the integrator proportionally to the control variable, a corresponding cut-off frequency of an equivalent low pass being coordinated automatically.
    • 提供了带有附加相敏检测器的锁相放大器。 测量信号以与调制频率相移90度的参考信号以乘法方式混合。 为了在最宽的动态范围内可靠地滤除干扰信号部分,并且同时将对有用信号部分的不可避免的影响减到最小,控制装置连接在附加的相敏检测器的下游。 控制装置根据来自与偏移90度的基准信号相位混合的测量信号确定与干扰信号的强度对应的控制变量,并且使用该控制变量将积分器的积分持续时间与控制变量成比例地变化, 自动协调等效低通的截止频率。

    • For the production and filling of (sheet-material) bags (10) with one tobacco portion (18) each, a plurality of bags (10) are preferably made available in the region of a filling station (20). The latter is located in the vicinity of a pressing station (19), which is supplied with the tobacco portions (18). In the region of the pressing station (19) or in a pressing chamber (35), each tobacco portion (18) is compressed in the vertical direction on a horizontal rest, namely on a platform (39), and in addition preferably compressed by a pressing crosspiece (42) in the horizontal direction. The tobacco portion (18) thus formed is introduced into the bag (10).

    • A user interface for entering option orders is disclosed. The user interface may include a display page having, a plurality of display objects and a display line. The plurality of display objects may represent individual options, individual spreads, and commands. The display line may depict the plurality of display objects stringed together in the order selected by a user. If at least two of the plurality of display objects selected are individual spreads, then a complex spread may be depicted on the display line. Upon the selection of a command, an order may be build consisting of the plurality of display objects depicted on the display line. The order may be built on a second display page. The second display page may color code each individual option and individual spread selected and may provide adjustable fields and buttons for data customization of each individual option and individual spread.
    • 公开了用于输入期权订单的用户界面。 用户界面可以包括具有多个显示对象和显示行的显示页面。 多个显示对象可以表示各个选项,个体差点和命令。 显示线可以按照用户选择的顺序描绘串在一起的多个显示对象。 如果所选择的多个显示对象中的至少两个是单独的展开,则可以在显示行上描绘复数展开。 在选择命令时,可以构建由在显示行上描绘的多个显示对象组成的顺序。 订单可以建立在第二个显示页面上。 第二显示页面可以对选择的每个单独选项进行颜色编码,并且可以为每个单独选项和单独展开的数据定制提供可调节的字段和按钮。
