A technique is disclosed for generating an acceleration profile indicative of a time history of an acceleration of a controlled object, to thereby generate at least one of a target velocity profile indicative of a time history of a target velocity of the controlled object and a target position profile indicative of a time history of a position of the controlled object. Utilizing integrated circuit manufacturing processes, a nanoscale, self-contained device has been developed to execute the process of electrospinning large arrays of fibers and fiber arrays. The queue threshold may accommodate the RTT delay of the link. The dynamic interbody devices may allow for coupled axial rotation and lateral bending of vertebrae adjacent to the dynamic interbody devices. The invention is intended to be used for replay or recording appliances for optical recording media with inclination control.
