    • In a high-speed serial link, an eye finder diagnostic circuit has improved performance by being on-chip with the existing capture latch(es) of a receive equalizer. The eye finder circuit employs an additional capture latch with its input tied to the same input node as the existing capture latch(es) of a receive equalizer. The additional capture latch has a clock input and reference voltage input. The clock input is adjusted through a phase interpolator (or variable delay line) while the reference voltage input is adjusted by a voltage generator. A digital post processing circuit then compares the output of the additional capture latch with the output of the other existing capture latch(es), in order to determine the receive eye opening. The horizontal eye opening is measured by changing the phase of the additional capture latch through the phase interpolator, while the vertical eye opening is measured by changing the reference voltage of the voltage generator of the additional capture latch. The eye finder circuit, being on-chip and in-line with existing capture latch(es), employs a minimum of power, minimum of area, and minimizes the extra loading to the existing equalizer output.
    • 在高速串行链路中,眼图仪诊断电路通过与现有的接收均衡器的捕获锁存器进行片上处理而提高了性能。 寻眼仪电路采用附加的捕捉锁存器,其输入端与接收均衡器的现有捕获锁存器连接到相同的输入节点。 附加捕捉锁存器具有时钟输入和参考电压输入。 通过相位内插器(或可变延迟线)调节时钟输入,而参考电压输入由电压发生器调节。 数字后处理电路然后将附加捕捉锁存器的输出与其他现有捕获锁存器的输出进行比较,以确定接收眼睛的开度。 通过改变相位插补器的附加捕获闩锁的相位来测量水平眼睛开度,而通过改变附加捕获闩锁的电压发生器的参考电压来测量垂直眼睛的开度。 片上并与现有捕获锁存器匹配的寻眼器电路采用最小功率,最小面积,并将额外负载最小化到现有的均衡器输出。

    • A system and a method of manipulating system parameters directly from displayed graphics utilize universal controls whose functions can vary depending on the current position of a cursor on a display device of the system. The system may be an imaging system based on ultrasound, magnetic resonance, computed tomography technology, or other modalities. The universal controls allow the number of controls included in the control panel of the system to be significantly reduced, since each universal control can perform functions of multiple hard controls. The universal controls may be pushbutton rotatable dials or rotatable toggles. In operation, when the cursor is positioned over one of the cursor-sensitive target areas, a control assignor of the system designates functions that correspond to that cursor-sensitive target area to the universal controls. The system also includes a display controller that controls the operations of displayed cursor-sensitive graphic elements. The cursor-sensitive graphic elements that are manipulated by the display controller include an annotation area, a pictogram area, toolbar buttons, and region of interest (ROI) controls. Depending on the selected cursor-sensitive graphic element, a menu of selectable graphics or an on-screen control may be displayed. The system also includes a selective print driver that operates to selectively prevent certain undesirable graphics from being printed.
    • 直接从显示图形操纵系统参数的系统和方法利用通用控制,其功能可以根据系统的显示装置上的光标的当前位置而变化。 该系统可以是基于超声,磁共振,计算机断层扫描技术或其它方式的成像系统。 通用控制允许显着减少系统控制面板中包含的控件数量,因为每个通用控件都可以执行多个硬控制的功能。 通用控制可以是按钮可旋转拨盘或可旋转切换。 在操作中,当光标位于一个光标敏感目标区域上时,系统的控制分配器将对应于该光标敏感目标区域的功能指定给通用控制。 该系统还包括控制显示光标敏感图形元素的操作的显示控制器。 由显示控制器操纵的对光标敏感的图形元素包括注释区域,象形图区域,工具栏按钮和感兴趣区域(ROI)控件。 根据所选择的光标敏感图形元素,可以显示可选图形的菜单或屏幕上的控制。 该系统还包括选择性打印驱动器,其操作以选择性地防止某些不需要的图形被打印。
