    摘要： This invention discloses a type of stepper motor driver integrated circuit, comprising of a control logic circuit module and a connected stepper motor driver circuit module. The outputs, in groups of two, of the stepper motor driver circuit module are connected to the two ends of coil windings in the stepper motor. Its characteristic is that it is equipped with an I2C serial bus connection which allows the main controller of I2C bus to directly connect to the control logic circuit module via the SDA, SCL, and GND lines resulting in duplex data transmission. With fewer number of signal ports, more driver integrated circuits can also be connected to the same I2C bus. Each driver integrated circuit can directly drive a stepper motor and it can also drive different numbers of stepper motors using different channels. In particular, the multi-channel stepper motor driver integrated circuit has fewer input contact points and thus it clearly reduces the chip area as well as the manufacturing cost which allows the chip to be used in a wide range of digital equipment and electronic information products where space is limited such as with cellular phone photo modules.

    摘要翻译： 本发明公开了一种步进电动机驱动器集成电路，其包括控制逻辑电路模块和连接的步进电动机驱动电路模块。 步进电机驱动器电路模块的两组输出端连接到步进电机的线圈绕组两端。 其特点是配有I2C串行总线连接，允许I2C总线的主控制器通过SDA，SCL和GND线直接连接到控制逻辑电路模块，从而进行双工数据传输。 使用较少的信号端口数量，更多的驱动器集成电路也可以连接到同一个I2C总线。 每个驱动器集成电路可以直接驱动步进电机，还可以使用不同的通道驱动不同数量的步进电机。 特别地，多通道步进电动机驱动器集成电路具有较少的输入接触点，因此显然降低了芯片面积以及制造成本，这使得芯片可用于广泛的数字设备和电子信息产品，其中 空间有限，如手机照片模块。

    摘要： An intelligent module pipeline, an intelligent module helical pipeline winding machine and a winding method thereof. In the cross section of the pipeline, a plurality of intelligent modules (1) are clamped and helically wound end to end to form a circular pipeline; each of the intelligent module units is an arch-shaped module which is formed by injection molding or compression molding; the each intelligent module unit is provided a reinforcing rib structure inside, a fixing device for fixing and clamping from left to right on the side surfaces, and a clamping device for fixing and clamping end to end at the edges. An arc-shaped chute rail is provided on the front surface of a working panel of the winding machine; the arc-shaped chute rail is provided with at least one pair of feed rollers (107), and is further provided with a locking device (108) and a parallel twisting device (106); the same intelligent module units are arranged end to end on the arc-shaped chute rail, and then are locked by means of the locking device, to form a semicircular pipe diameter by means of the feed rollers; then the parallel twisting device twists the semicircular pipe diameter in parallel to change the winding rail; and the intelligent module units are wound in a staggered arrangement to form helical winding pipelines.

    摘要： A method computer implemented method of minimizing connections in a distributed system includes traversing paths in a directed graph representation of the distributed system having a fixed set of paths between nodes representing resources of the distributed system and edges representing connections between the resources by performing a random walk procedure to provide a reduced number of paths in the directed graph representation, and identifying excessive connections between the resources by simulating a client accessing the resources and identifying as excessive, connections that are not used by any of the reduced number of paths, wherein the excessive connections are removable from the distributed system without preventing client access to resources in the distributed system.
