    • A data recording medium, such as a magnetic recording hard disk, has data tracks with pseudo-random binary sequences for the servo information used to control the position of the recording head in the disk drive. A first pseudo-random binary sequence (PRBS) and a second PRBS identical to the first PRBS but shifted by a portion of the period of the first PRBS are located between the track boundaries in alternating tracks in a first region of the servo pattern and between the track centers in alternating tracks in a second region spaced along the track from said first region. A servo decoder in the disk drive has two correlators, one for each PRBS. Each correlator outputs a dipulse when its PRBS repeats. The difference in amplitude of the dipulses represents the head position signal. The dipulses also control the amplifier for the signal read back by the head and the timing of the track identification (TID) detector.
    • 诸如磁记录硬盘的数据记录介质具有用于伺服信息的伪随机二进制序列的数据轨道,用于控制磁盘驱动器中的记录头的位置。 第一伪随机二进制序列(PRBS)和与第一PRBS相同但被第一PRBS的周期的一部分移位的第二PRBS位于伺服模式的第一区域中的交替轨道中的轨道边界之间,并且位于 所述轨道在与所述第一区域沿所述轨道间隔开的第二区域中的交替轨道中心。 磁盘驱动器中的伺服解码器具有两个相关器,每个PRBS一个。 当PRBS重复时,每个相关器输出dipulse。 二次脉冲的幅度差表示磁头位置信号。 该信号还可控制放大器的头部读取信号和磁道识别(TID)检测器的定时。

    • 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靶容器的远端的柔性轴。 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。

    • A bleed back control assembly and method for controlling blood loss during catheterization procedures includes a side arm body connected at the proximal end to a seal body. The side arm body comprises one or more branches, each having a lumen, and a finger rest on the exterior of at least one branch. The seal body comprises a cap assembly and a seal assembly. The seal assembly comprises a clamp seal and a bleed back seal, both made of elastomer and held by a seal holder. The cap assembly comprises a threaded cap and a funnel cap. The threaded cap is connected to the seal holder. Rotation of the threaded cap causes the clamp seal to open or close. The funnel cap comprises a dilator, and pressing the funnel cap causes the dilator to open an aperture in the bleed back control seal. A spring, wound around the dilator, returns the funnel cap to its original position, thus closing the bleed back seal. The bleed back seal self-sizes to devices introduced through its aperture. Dilating the bleed back control seal also allows purging of gases or fluids. The clamp seal can clamp a device introduced transluminally to maintain device position, and the clamp seal may also be closed to allow high pressure injections.
    • 用于在导管插入术过程中控制失血的排泄控制组件和方法包括在近端连接到密封体的侧臂体。 侧臂体包括一个或多个分支,每个分支具有内腔,以及在至少一个分支的外部上的手指支撑。 密封体包括盖组件和密封组件。 密封组件包括由弹性体制成并由密封保持器保持的夹紧密封件和泄放背部密封件。 盖组件包括螺纹盖和漏斗盖。 螺纹盖连接到密封夹。 螺纹帽的旋转导致夹紧密封件打开或关闭。 漏斗帽包括扩张器,并且按压漏斗帽使得扩张器打开放回控制密封件中的孔。 缠绕在扩张器周围的弹簧将漏斗盖返回到其原始位置,从而关闭泄放密封。 通过其孔径引入的装置,泄放背部密封件自身尺寸。 放泄回流控制密封件还可以清除气体或流体。 夹紧密封件可以夹紧一个装置,以维持装置的位置,也可以将夹紧密封件封闭以允许高压注射。
