摘要： The present invention relates to a compact motorized rotational stage for microscopy applications and control methods for automated sample orientation/rotation. The rotational stage includes a motor, a rotational motion transmission mechanism, and a rotating sample holder for accommodating a holding device such as glass slides/Petri dishes of different sizes. Mouse embryos are used as an example to explain the control methods. A pattern recognition utility was developed for identifying mouse embryo structures. The transformation between the holding device rotational coordinate frame and the translational positioning stage coordinate frame is calibrated during image-based visual servo control. The polar body of an embryo is oriented through purely image-based visual servo control or through coordinate transformation and closed-loop position control.

摘要： A servo system for a hard disk drive comprising a first actuator, a second actuator, a head, and a disk on which is formed a plurality of tracks containing servo data. The servo system comprises a first stimulus, a second stimulus, and a calibration system. The first stimulus causes the first actuator to move the head to at least two calibration tracks on the disk. The second stimulus causes the second actuator to move the head relative to the at least two calibration tracks. The calibration system generates a calibration factor based on the second calibration signal and the movement of the second actuator relative to each of the at least two calibration tracks.

摘要： Methods of controlling seeking of a transducer that is adjacent to a rotatable disk in a disk drive are disclosed. The methods may include accelerating the transducer radially across the rotatable disk from an initial track on the rotatable disk toward a destination track on the rotatable disk, estimating a deceleration switching position/velocity point, estimating a maximum deceleration position/velocity point following the deceleration switching position/velocity point, and estimating a deceleration current required to decelerate the transducer from a non-zero velocity at the maximum deceleration position/velocity point to zero velocity at the destination track. The estimated deceleration current is compared to a maximum available deceleration current, and responsive to a determination that the current required to decelerate the transducer from the maximum deceleration point to the destination track exceeds the maximum available deceleration current, the estimated deceleration switching point is adjusted. Related disk drive apparatus are also disclosed.
