    • A process and apparatus for measurement of nonuniformity of mass of a gyro rotor having a single bearing. The gyro rotor, which is mounted in a radially fixed and spherically yielding pivot, is rotated to a predetermined speed. The static imbalance of the rotating rotor is then determined by measuring the magnitude and angular position of excursion of the rotating rotor. A force couple acting on the gyro rotor and drift of mass of the gyro rotor are determined by sensing movement of a surface of the rotating rotor at two different times. Preferably, the determination of static imbalance, force couple, and drift are obtained in a single course of measurement. After the preceding have been measured, the components of a mass balancing operation for correcting the measured nonuniformities are determined.
    • 用于测量具有单个轴承的陀螺仪转子的质量不均匀的过程和装置。 安装在径向固定和球形屈服枢轴中的陀螺仪转子旋转到预定速度。 然后通过测量旋转转子的偏移的大小和角位置来确定旋转转子的静态不平衡。 通过感测旋转转子的表面在两个不同时间的移动来确定作用在陀螺仪转子上的力耦合和陀螺仪转子的质量漂移。 优选地,在单个测量过程中获得静态不平衡,力耦合和漂移的确定。 在测量前述之后,确定用于校正测量的不均匀性的质量平衡操作的分量。

    • A spinal fixation apparatus comprising an upper and lower endplate. Depending distally in a longitudinal direction from the upper endplate is an inner sleeve that fits inside an outer sleeve that depends distally in a longitudinal direction from the lower endplate. The inner sleeve includes grooves located on its outer surface. A finger cage including resilient fingers fits around the outer sleeve. The fingers have ends that include male grooves. The ends of the fingers fit into apertures located in the outer sleeve. The apparatus further includes a locking mechanism that pushes the tips of the fingers through the apertures of the outer sleeve such that they mesh with the grooves of the inner sleeve. When the locking mechanism is unlocked the tips of the fingers disengage from the grooves of the inner sleeve, and the inner sleeve slide axially within the outer cage, adjusting the height of the device.
    • 一种脊柱固定装置,包括上端板和下端板。 沿着从上端板的纵向方向向远侧方向是内套筒,其配合在从下端板沿纵向方向远离的外套筒的内侧。 内套筒包括位于其外表面上的凹槽。 包括弹性指状物的手指保持架围绕外套筒配合。 手指具有包括阳凹槽的端部。 手指的端部装配到位于外套筒中的孔中。 该装置还包括锁定机构,其通过外套筒的孔推动手指的尖端,使得它们与内套筒的凹槽啮合。 当锁定机构解锁时,手指的尖端与内套筒的槽脱离,并且内套筒在外笼内轴向滑动,调节装置的高度。

    • An anterior spinal fixation system comprises a plurality of mounting constructs to hold one or more spinal rods or spinal plate-type braces. Each mounting construct includes a bottom plate and a top plate assembly. The bottom plate is attached to the vertebral body with a plurality of anchors, one or more of which may be polyaxial. In one embodiment, the top plate assembly engages the bottom plate through a quick-connect feature that provides simple and secure locking as well as tactile feedback. When the top plate assembly is engaged with the bottom plate, it compresses the rods or braces against the head of the screws, locking the angle of any polyaxial bone screws. In another embodiment, the top plate assembly threadably engages the bottom plate. For additional strength and rigidity, cross-connectors may be used between each pair of mounting constructs when two or more spinal rods are used.
    • 前脊椎固定系统包括多个安装结构,用于保持一个或多个脊柱杆或脊椎板型支架。 每个安装结构包括底板和顶板组件。 底板用多个锚固件附接到椎体,其中一个或多个可以是多轴的。 在一个实施例中,顶板组件通过快速连接特征接合底板,其提供简单和安全的锁定以及触觉反馈。 当顶板组件与底板接合时,它将杆或支架压靠在螺钉的头部上,锁定任何多轴骨螺钉的角度。 在另一个实施例中,顶板组件可螺纹地接合底板。 为了增加强度和刚度,当使用两个或更多个脊柱杆时,可以在每对安装结构之间使用交叉连接器。
