    • Systems and methods are described for bonding asynchronous transfer mode permanent virtual circuits using a multi-link segmentation and reassembly sublayer. A method includes: transforming a stream of asynchronous transfer mode cells into a stream of bonded asynchronous transfer mode cells; demultiplexing the stream of bonded asynchronous transfer mode cells into a plurality of streams of inverse multiplexed bonded asynchronous transfer mode cells; and transmitting the plurality of streams of inverse multiplexed bonded asynchronous transfer mode cells to a remote location via a plurality of permanent virtual circuits, characterized in that the transmitted plurality of streams of inverse multiplexed bonded asynchronized transfer mode cells can be multiplexed into a multiplexed stream of asynchronized transfer mode cells after transmission via at least two permanent virtual circuits, which compose the plurality of permanent virtual circuits, that do not have an identical bit-rate.

    • A method and a system are disclosed for adaptively controlling a stepper motor to produce a required torque output based on selection information provided by a sensor or a user/user interface which, in combination with a selector, selects a torque-related value. The selection information provided to the selector for selecting the stepper motor torque-related value may be, for example, the size or thickness of material being handled or the number of accumulated sheets for processing. The torque-related value is predetermined through experimentation and loaded into a lookup table stored in the memory of a motion control system board. The selected torque-related value is provided to a stepper motor driver which supplies the appropriate drive signal(s) to the stepper motor.
    • 公开了一种方法和系统,用于根据由选择器选择转矩相关值的传感器或用户/用户接口提供的选择信息来自适应地控制步进电机以产生所需的转矩输出。 提供给用于选择步进电动机转矩相关值的选择器的选择信息可以是例如正在处理的材料的尺寸或厚度或用于处理的累积纸张的数量。 扭矩相关值通过实验预先确定并加载到存储在运动控制系统板的存储器中的查找表中。 所选择的转矩相关值被提供给步进电动机驱动器,该步进电动机驱动器将适当的驱动信号提供给步进电动机。
