    • Techniques are provided for identifying the servo sectors in a track on a data storage device. A data storage device identifies the servo sectors in a track by reading distributed index bits from multiple servo sectors in a track. The data storage device analyzes only one index bit from each servo sector to identify the index of a track. In some embodiments, the index of a track can be identified after examining the index bits stored in a particular number of consecutive servo sectors, even in the presence of errors. The index bits in each track can have an error tolerance with a minimum Hamming distance greater than one. In other embodiments, a data storage device compares a sliding window of the index bits read from the servo sectors to all possible N-bit vectors that exist within a pattern of the index bits stored on a track.
    • 提供了用于识别数据存储设备上的轨道中的伺服扇区的技术。 数据存储装置通过从轨道中的多个伺服扇区读取分布式索引位来识别轨道中的伺服扇区。 数据存储设备仅分析来自每个伺服扇区的一个索引位以识别轨道的索引。 在一些实施例中,即使存在错误,也可以在检查存储在特定数量的连续伺服扇区中的索引位之后识别轨道的索引。 每个轨道中的索引位可以具有大于1的最小汉明距离的误差容差。 在其他实施例中,数据存储装置将从伺服扇区读取的索引位的滑动窗口与存储在轨道上的索引位的模式中存在的所有可能的N位向量进行比较。

    • The present disclosure describes a method and apparatus for guide catheterization. In one embodiment, a guiding catheter system includes a flexible shaft having a distal end shaped for accessing a target vessel. A handle assembly is movably coupled to the flexible shaft. The flexible shaft is selectably movable between a plurality of discrete positions of a first degree-of-freedom defined relative to the flexible shaft. The flexible shaft restrained in the first degree-of-freedom at each position of the plurality of discrete positions. The flexible shaft movable through a predetermined displacement of a second degree-of-freedom defined relative to the flexible shaft at each position of the plurality of discrete positions. Motion of the flexible shaft relative to the handle assembly results in a controllable sweeping motion at the distal end of the flexible shaft.
    • 本公开描述了用于引导导管插入术的方法和装置。 在一个实施例中,引导导管系统包括具有成形为用于接近目标血管的远端的柔性轴。 手柄组件可移动地联接到柔性轴。 柔性轴可选择地在相对于柔性轴限定的第一自由度的多个离散位置之间移动。 柔性轴在多个离散位置的每个位置处以第一自由度限制。 柔性轴可在多个离散位置的每个位置处移动通过相对于柔性轴限定的第二自由度的预定位移。 柔性轴相对于手柄组件的运动导致在柔性轴的远端处的可控的扫掠运动。
