    摘要： 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.

    摘要： A spinal fixation device including two plates and a coupling element for coupling the plates in a fixed manner about adjacent spinous processes of the spine. Each plate is preferably equipped with integral spikes on the inwardly facing surfaces for pressing into the spinal processes and thereby augmenting the purchase between the plates and the spinous processes. Each plate contains a central aperture through which the coupling element passes in order to couple the plates together.

    摘要： 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.
