    • A movable partition system includes a movable partition including coupled panels and a lead post engaged with and movable along a track. A motor control system includes a motor coupled to the movable partition and a switching circuit coupled to the motor and for selectively coupling the motor to a positive power source and a negative power source responsive to one or more PWM signals. An encoder is configured for generating one or more rotation signals indicative of operational direction and operational speed of the motor. A motor controller is coupled to the switching circuit and is configured for improving airflow around the panels of the movable partition when the lead post of the movable partition is between a predefined position and a fully retracted position indicative of a billowing effect for the panels by adjusting pulse widths of the PWM signals to control rotational speed of the motor.
    • 可移动分隔系统包括可移动分隔件,其包括联接面板和与轨道接合并可移动的引导柱。 电动机控制系统包括耦合到可移动隔板的电动机和耦合到电动机的开关电路,并且用于根据一个或多个PWM信号选择性地将电动机耦合到正电源和负电源。 编码器被配置用于产生指示电动机的操作方向和操作速度的一个或多个旋转信号。 电动机控制器耦合到开关电路并且被配置为当可移动隔板的引导柱位于预定位置和完全缩回位置之间时改善围绕可移动隔板的面板的气流,从而指示面板的滚动效应通过调节 PWM信号的脉冲宽度来控制电机的转速。

    • Various apparatuses, methods and systems for directionally controlling a movable partition are provided. In one embodiment, an apparatus may include at least one roller assembly coupled to a portion of a movable partition. A roller element of the roller assembly may be configured to maintain contact with an adjacent surface (e.g., a floor) while the partition is displaced along a desired path even though the adjacent surface may exhibit unevenness, undulations or other substantially nonplanar surface features. In one embodiment, the apparatus may be configured to maintain a substantially constant force between the roller element and the adjacent surface. In another embodiment, the apparatus may be configured to maintain a force between the roller element and the adjacent surface substantially within a specified range. A steering actuator may also be used to select, or change, the orientation of the roller assembly with respect to the partition.
    • 提供了用于定向控制可移动分隔件的各种装置,方法和系统。 在一个实施例中,装置可以包括耦合到可移动隔板的一部分的至少一个辊组件。 辊组件的滚子元件可被构造成保持与相邻表面(例如,地板)的接触,同时尽管相邻的表面可能表现出不均匀性,起伏或其它基本上非平面的表面特征,但是隔板沿期望的路径移位。 在一个实施例中,该装置可以被配置为在辊元件和相邻表面之间保持基本恒定的力。 在另一个实施例中,该装置可以被配置为在滚子元件和相邻表面之间维持大致在特定范围内的力。 转向致动器还可以用于选择或改变辊组件相对于隔板的取向。
