| Zusammenfassung: | The present invention is a method and apparatus for regulating the velocity of a member constrained to move about a predefined path. The invention comprises a magnetic patch or strip, located on a surface of the member, and having a plurality of magnetic signals recorded thereon, along with a magnetic detector, positioned in proximity to said magnetic strip, for sensing the magnetic signals recorded thereon, during movement of the member, and producing an output signal in response to the magnetic signals. The invention further comprises means, operatively connected to impart a driving force to the member, and control means for regulating said driving means so that the member is driven at a velocity which is a function of the output signal. |
