摘要： Attaching an attachment surface of an electrically conductive workpiece to an electrically conductive support surface is described. In one aspect, a biasing force is distributed at least partially around a weld region of the workpiece to urge the attachment surface of the workpiece against the support surface in a way which at least resists welding induced movement of the workpiece relative to the support arrangement. An electrode arrangement, having an electrode tip, contacts the workpiece to provide for substantially compliant movement of the electrode tip against the weld region in directions that are parallel to the support surface. In another aspect, a combined manipulation/welding arrangement is supported for controlled movement with a free end configured for engaging the workpiece to bias the workpiece against the support surface to manipulate the workpiece against the surface and to conduct an electrical current, while holding the workpiece, for welding to the support surface.

摘要： A method of optimizing SBS suppression is disclosed for use in an optical communication system including a light guide for transmitting light and means for producing phase modulation of the light using at least first and second tones. In the method, an operational region of SBS suppression is established as a function of the phase modulation of the light such that the operational region identifies combinations of first and second phase modulation levels at which optimum SBS suppression is achieved for the first and second tones. Thereafter, based on the operational region, the first and second phase modulation levels are adjusted such that the system operates with optimum SBS suppression. In one aspect, a contour map and associated method are introduced. The contour map is especially suited for use in optimizing SBS suppression in an optical communication system in which light is phase modulated using at least first and second tones for transmission of the phase modulated light via media which exhibits an SBS threshold. In another aspect, one of the sub-regions identified by the contour map may be selected as the operating point of the system based on certain characteristics of the contour map at and around the location of the selected operating point. In this manner, for example, the stability of the optical communication system may be improved in the event that the selected operating point is subject to drift.
摘要翻译：公开了一种优化SBS抑制的方法，用于包括用于发射光的光导的光通信系统和用于使用至少第一和第二音调产生光的相位调制的装置。在该方法中，SBS抑制的操作区域被建立为光的相位调制的函数，使得操作区域识别第一和第二相位调制电平的组合，在第一和第二相位调制电平处获得针对第一和第二音调的最佳SBS抑制。此后，基于操作区域，调整第一和第二相位调制电平，使得系统以最佳SBS抑制运行。在一个方面，引入了轮廓图和相关联的方法。轮廓图特别适合用于优化光通信系统中的SBS抑制，其中使用至少第一和第二音调对光进行相位调制，以便通过显示SBS阈值的介质传输相位调制光。在另一方面，基于轮廓图识别的子区域中的一个可以基于所选择的操作点的位置处和周围的轮廓图的某些特征被选择为系统的操作点。以这种方式，例如，在所选择的操作点经受漂移的情况下，可以改善光通信系统的稳定性。
