摘要： A wire bonding apparatus, comprising a bonding tool mounted on a bondhead body which is in turn mounted on a positioning table, is provided for bonding electronic devices. The positioning table has first and second motors coupled to it that are operative to drive the bondhead body to positions along respective first and second orthogonal axes. The bondhead body is connected to the positioning table through a pivot such that the bondhead body is rotatable relative to the positioning table about a third axis which is substantially orthogonal to the first and second axes. Further, a third motor drives the bondhead body to rotate about the third axis.

摘要： There are disclosed systems and methods for detecting whether an Optical Network Unit (ONU) in a network may be causing a communications interference due to laser overlap. In one embodiment, an Optical Line Terminal (OLT) selects a pair of ONUs suspected of possibly causing laser overlap. The OLT then grants a first window to a first ONU for transmitting a first message, and grants to another ONU different from the pair of ONUs a second window for transmitting a second message. If the first message is not received by the OLT, then the OLT indicates that the first ONU may be causing laser overlap. In another embodiment, the OLT grants to an ONU a window for transmitting a message to the OLT. If the message is not received by the OLT when expected, then the OLT indicates that the ONU may be causing laser overlap. Other embodiments are disclosed.
摘要翻译：公开了用于检测网络中的光网络单元（ONU）是否可能由于激光重叠而导致通信干扰的系统和方法。在一个实施例中，光线路终端（OLT）选择疑似可能引起激光重叠的一对ONU。然后，OLT向第一ONU授予用于发送第一消息的第一窗口，并且向与该对ONU不同的另一个ONU授予用于发送第二消息的第二窗口。如果OLT没有接收到第一个消息，则OLT指示第一个ONU可能导致激光重叠。在另一个实施例中，OLT向ONU授予用于向OLT发送消息的窗口。如果OLT预期不接收到该消息，则OLT指示ONU可能导致激光重叠。公开了其他实施例。

摘要： There are disclosed techniques for power control in an Optical Network Unit (ONU) of a Passive Optical Network (PON). In one embodiment, the supply of power to an optical transmitter is controlled in accordance with information defining a plurality of transmission windows during which data can be transmitted from the ONU, in order to achieve the following: (1) to provide power to the optical transmitter beginning at a predetermined time in advance of a transmission window to ensure a laser in the optical transmitter is ready to begin transmitting the data at the start of the transmission window; and (2) to refrain from providing full power to the optical transmitter between transmission windows when the duration of time between the transmission windows is greater than a predetermined length.
摘要翻译：公开了一种用于无源光网络（PON）的光网络单元（ONU）中的功率控制的技术。在一个实施例中，根据定义可从ONU发送数据的多个传输窗口的信息来控制向光发射机的电力供应，以实现以下目的：（1）向光学系统提供电力发射机在传输窗口之前的预定时间开始，以确保光发射机中的激光准备好在传输窗口开始时开始传输数据; 和（2）当传输窗口之间的持续时间大于预定长度时，避免向传输窗口之间的光发送器提供全部电力。
