A circuit board manufacturing system is provided which includes a production assembly line with a carrier handling system for a plurality of feederprogrammingbuffer systems. The disclosed device enables improved needle orientation control and avoids direct exposure of the clinician’s hand to X-ray during the puncturing procedure. The current-loop neural network can be configured to optimize the compensating dq-control voltage. The radiation energy is increased andor decreased. The repulsion of the second magnet assembly maintains the beam in either the first or second position until the beam is selectively actuated therefrom. Features can capture personal idiosyncrasies or systematic patterns of usage.
