    • A method of adjusting a size of a base transceiver station (BTS) search window for adjusting the size of the search window, which the BTS uses to acquire a signal of a mobile station, according to a service radius and modifying a location of the search window, thereby improving efficiency in acquiring an access signal and controlling a service area. The method comprises the steps of: determining a service radius in which the BTS can acquire an access signal of a mobile station; reading a size of a preamble search window and a preamble search range corresponding to the determined service radius from a table used for determination of the size of the search window, the table being stored in a database; and modifying the size of the search window by changing search window parameters of the BTS system according to the read search range and the size of the search window for the preamble.
    • 一种调整基站收发台(BTS)搜索窗口的大小的方法,用于根据服务半径调整BTS用于获取移动台信号的搜索窗口的大小,并修改搜索的位置 从而提高获取访问信号的效率和控制服务区域。 该方法包括以下步骤:确定BTS可以获取移动台的接入信号的服务半径; 从用于确定搜索窗口的大小的表中读取与所确定的服务半径相对应的前导码搜索窗口的大小和前导码搜索范围,该表存储在数据库中; 以及通过根据读取的搜索范围和用于前导码的搜索窗口的大小改变BTS系统的搜索窗口参数来修改搜索窗口的大小。

    • A wireless small motor driver, in which power consumption is decreased by adjusting a gear ratio, the efficiency of an operation is increased due to a high torque, and the safety of a worker at night is ensured using an illumination lamp. The wireless small motor driver includes a driver case inside of which a motor is provided. A driver bit has a predetermined length in a bilateral direction, the driver bit being replaceable, with one or both ends thereof conforming to the shape of a bolt, and has a fixing projection. A socket is coupled to an end portion of the driver case, the driver bit being fastened to the socket. A rotation reduction gear is coupled to the motor, the rotation reduction gear transmitting rotary force to the socket and increasing a torque. A USB and a battery for supplying uniform power to the motor are added.
    • 通过调节传动比来降低功耗的无线小型电动机驱动器,由于高转矩,操作效率提高,并且使用照明灯确保夜间工作人员的安全。 无线小型电动机驱动器包括驱动器壳体,内部设置有电动机。 驾驶员位在双向方向上具有预定长度,驾驶员位可更换,其一端或两端与螺栓的形状一致,并且具有固定突起。 插座耦合到驱动器壳体的端部,驱动器钻头被紧固到插座。 旋转减速齿轮联接到电动机,旋转减速齿轮将旋转力传递到插座并增加转矩。 增加了一个USB和一个用于向电机提供均匀电源的电池。
