    Abstract: Provided is a method of preventing a data collision that occurs when two or more child nodes simultaneously transmit data to a parent node in a ZigBee network having a tree routing scheme and operating in a beacon mode. In the ZigBee system having the tree routing scheme and operating in the beacon mode, data communication to the parent node is performed in a beacon frame of the parent node. Here, when several child nodes exist under a single parent node, the child nodes transmit data to the parent node at the moment of receiving the beacon of the parent node, so that the data collision may occur when the child nodes simultaneously transmit the data to the parent node in the beacon frame of the parent node. In the method of preventing a data collision, each of the two or more child nodes is set to wait for its guard time (delay time) when transmitting data to the parent node to induce a normal slotted carrier sense multiple access with collision avoidance (CSMA-CA) operation. Therefore, the data collision can be prevented.

    Abstract translation: 提供了一种防止当两个或多个子节点同时向具有树路由方案并且以信标模式操作的ZigBee网络中的父节点发送数据时发生的数据冲突的方法。 在具有树路由方案并在信标模式下操作的ZigBee系统中，在父节点的信标帧中执行到父节点的数据通信。 这里，当在单个父节点下存在几个子节点时，子节点在接收到父节点的信标的时刻向父节点发送数据，使得当子节点同时发送数据时可能发生数据冲突 父节点的信标帧中的父节点。 在防止数据冲突的方法中，将两个或多个子节点中的每一个设置为在向父节点发送数据时等待其保护时间（延迟时间），以引起具有防冲突的正常时隙载波侦听多路访问（CSMA -CA）操作。 因此，可以防止数据冲突。

    Abstract: An ion implanting system and a wafer holding apparatus therefor are provided. The ion implanting system includes x- and y-axis rotating parts; first and second angle measuring circuits; and a controller. The x-axis rotating part rotates a main surface of a wafer about an x-axis, and the y-axis rotating part rotates the main surface of the wafer about a y-axis. The first angle measuring circuit is rotated along with the main surface of the wafer and measures a tilt angle of the main surface of the wafer with respect to the x-axis. The second angle measuring means is rotated along with the main surface of the wafer and measures a rotating angle of the main surface of the wafer with respect to the y-axis. The controlling part, when the measured tilt angles are different from target tilt angles, controls the x- and y-axis rotating parts such that the measured tilt angles are equal to the target tilt angles. In the present invention, the ion implanting system and the wafer holding apparatus therefor can measure and monitor an incidence angle of an ion beam with respect to a tilted wafer.
