A method and apparatus for synchronizing system operations using a programmable element.

摘要

The control system provides for the synchronization of at least one operating element (125) that has a desired relationship relative to a movable element (115). The movable element (115) is set into motion in a prescribed and controlled manner. A reference signal (200) is derived from the movable element (115) such that the reference signal (200) is representative of the position of movable element (115). This reference signal (200) can represent either the absolute position or relative position of the movable element (115). This reference signal (200) is applied to the input of a programmable element (2). The programmable element (2) processes this reference signal (200) to generate control signal(s) (230) for the desired control state of the operating element(s) (125). The control signal(s) (230), either directly or indirectly, control the operating element(s) (125). <IMAGE>
