  • Simplified spine testing device
    Patent number: 9378662
    Abstract: A sample testing device includes a motor, a gear reducer, and an output shaft coupled for rotation by the motor via the gear reducer. The sample testing device further includes a first device adapted to enable the output shaft to move linearly in a first direction substantially parallel with an axis of the output shaft and a second device coupled to the first device for enabling the output shaft to move linearly in a second direction substantially perpendicular to the first direction. The sample testing can further include a third device coupled to the first and second devices for enabling the output shaft to translate linearly in a third direction substantially perpendicular to the first and second directions.
