    • A scroll-free user interface comprises a display area; an interface panel included within the display area; and a data panel. The data panel includes a portion of a set of data items. The size and number of data items in the portion of the set of items is based on the size of the data panel. A user interface comprises a display area; an interface panel included within the display area; a first user interface control; and a layered user interface element. Web pages are analyzed to identify associated electronic documents. A retrieved web page is analyzed to identify at least one dynamic element. The dynamic element is analyzed to determine a network location of at least one associated electronic document. The dynamic element may be analyzed by applying a pattern matching or by executing the dynamic element to identify the network location of at least one associated electronic document.

    • An apparatus for sensing and correcting force levels and vibrational frequencies in a cylindrical grinding machine which has active centers. The active centers have imbedded shear load sensors and imbedded actuators. The sensors provide real time grinding information and allow for a determination of undesirable force levels and vibrational frequencies. The actuators are a pair of piezoelectric stacks disposed on opposing sides of the center body in indentations. A voltage applied by a controller causes the piezoelectric stacks to expand and contract. The action of the piezoelectric stacks causes the tip of the center to laterally displace and apply a lateral force to the workpiece. An AC voltage waveform may be applied for force control. A DC voltage may be applied for displacement; for example, to rapidly remove the workpiece from the grinding wheel or to correct for misalignment between the workpiece and the wheel. Because the sensors and actuators are imbedded, they do not interfere with the work space or machine components. In addition, the sensors and actuators are formed in standard sized centers so that the active centers may easily retrofit existing machines.
    • 一种用于感测和校正具有活动中心的圆柱形磨床中的力水平和振动频率的装置。 活动中心嵌入了剪切载荷传感器和嵌入式执行器。 传感器提供实时研磨信息,并允许确定不期望的力水平和振动频率。 致动器是一对压电叠层,其设置在中心体的相对侧的压痕中。 由控制器施加的电压使得压电叠层膨胀和收缩。 压电叠层的作用导致中心的尖端横向移位并向工件施加横向力。 交流电压波形可用于力控制。 可以施加直流电压用于位移; 例如,从砂轮快速移除工件或校正工件和车轮之间的未对准。 因为传感器和执行器是嵌入式的,它们不会干扰工作空间或机器部件。 此外,传感器和执行器形成在标准尺寸的中心,使得活动中心可以容易地改造现有的机器。
