    • The present invention relates to the error control method in inter-multi-user multimedia communication. There are error detection, error reporting and error recovery functions in the conventional error control method which finds out and solve the error occurring at the time of data transmission between transmitter and receiver, however, these functions are an error control method occurring in end-to-end communication consisting of one transmitter and one receiver and are not appropriate to solving errors occurring concurrently and in a bundle between one or some transmitters and many receivers in many-to-many multiple points inter-multi-user communication such as multimedia communication. Therefore, the present invention uses the damping technique to minimize the number of error control packets of which all the receiver having sensed the error concurrently request the resend based on the NACK.
    • 本发明涉及多用户多媒体通信中的错误控制方法。 在传统的误差控制方法中存在错误检测,错误报告和错误恢复功能,发现和解决了发射机和接收机之间的数据传输时发生的错误,但这些功能是一种错误控制方法, - 由一个发射机和一个接收机组成的通信,并不适合解决多对多用户通信(如多媒体通信)中多个到多个多点同时发生的一个或多个发射机与许多接收机之间的并发发生的错误。 因此,本发明使用阻尼技术来最小化所有接收机已经感知出错误的错误控制分组的数量,同时基于NACK请求重新发送。

    • Disclosed herein is a method of inspecting defects in a circuit pattern of a substrate. At least one laser beam radiation unit for radiating a laser beam onto an inspection target circuit pattern of a substrate in a non-contact manner is prepared. A probe beam radiation unit for radiating a probe beam onto a connection circuit pattern to be electrically connected to the inspection target circuit pattern in a non-contact manner is prepared. The laser beam is radiated onto the inspection target circuit pattern using the laser beam radiation unit. The probe beam is radiated onto the connection circuit pattern using the probe beam radiation unit, thus measuring information about whether the probe beam is diffracted, and a diffraction angle. Accordingly, the method can solve problems such as erroneous measurements caused by contact pressure and can reduce the time required for measurements.
    • 本文公开了一种检查基板的电路图案中的缺陷的方法。 制备用于以非接触方式将激光束照射到基板的检查对象电路图案上的至少一个激光束辐射单元。 准备用于以不接触的方式将探测光束照射到连接电路图案以电连接到检查对象电路图案的探测光束辐射单元。 使用激光束辐射单元将激光束照射到检查对象电路图案上。 使用探测光束辐射单元将探测光束照射到连接电路图案上,从而测量关于探针光束是否衍射的信息和衍射角。 因此,该方法可以解决诸如由接触压力引起的误差测量等问题,并且可以减少测量所需的时间。
