2-D Correlated Electromagnets

Correlated magnetics can be implemented using a two-dimensional array of electromagnets, where a control system can control whether a given electromagnet is off, a positive magnetic source, or a negative source.  Fig. 1 depicts a work table having a workpiece placed upon it. 

Fig. 1. Work Table with 2D Electromagnet Array

In Fig. 1, a cutout of the work table shows that beneath its surface is a two-dimensional array of electromagnets (an “ EM array”).   The four members of the work piece each have correlated magnetic structures that reside on the topside of the work table.  Fig. 2 depicts electromagnets of the EM array changing state as controlled by a control system.

In Fig. 2, a pattern is indicated for a portion of the EM array that would be “activated” beneath one of the members of the work piece, where similar activation would occur beneath each of the four members.  The magnetic structures would correlate so as to attach to the work table.  By then electronically moving the portions of the EM array to different locations the correlated magnetic structures of the work piece will move accordingly.  Thus, the positioning and movement of the work piece can be precisely controlled without mechanical mechanisms such as cabling, chains, gears, etc. such as in used in conventional manufacturing areas.  Multiple work pieces can move about each other including one passing beneath another, or over another, etc.  Very importantly, because a correlated magnetic holding force is being used to attach the work piece to the work table and to control its movement, the table can be oriented in space as desired to include vertically, upside down, etc.  As such, correlated magnetics implemented with 2D EM arrays enables the full three-dimensional area of a building to be efficiently utilized.
