1. A device comprising:
- a cover including a first field emission structure; and
a compartment including a second field emission structure, where the cover is attached to the compartment to enclose a space within the compartment when the first and second field emission structures are located next to one another and have a certain alignment with respect to one another, where each of the first and second field emission structures include field emission sources having positions and polarities relating to a desired spatial force function that corresponds to a relative alignment of the first and second field emission structures within a field domain, said spatial force function being in accordance with a code, said code corresponding to a code modulo of said first plurality of field emission sources and a complementary code modulo of said second plurality of field emission sources, said code defining a peak spatial force corresponding to substantial alignment of said code modulo of said first plurality of field emission sources with said complementary code modulo of said second plurality of field emission sources, said code also defining a plurality of off peak spatial forces corresponding to a plurality of different misalignments of said code modulo of said first plurality of field emission sources and said complementary code modulo of said second plurality of field emission sources, said plurality of off peak spatial forces having a largest off peak spatial force, said largest off peak spatial force being less than half of said peak spatial force.

18. A method for enabling a cover to be attached to and removed from a compartment within a device, said method comprising the steps of:
-
attaching a first field emission structure to the cover; attaching a second field emission structure to the compartment; and aligning the first and second field emission structures so the cover attaches to the compartment and encloses a space within the compartment when the first and second field emission structures are located next to one another and have a certain alignment with respect to one another, where each of the first and second field emission structures include field emission sources having positions and polarities relating to a desired spatial force function that corresponds to a relative alignment of the first and second field emission structures within a field domain, said spatial force function being in accordance with a code, said code corresponding to a code modulo of said first plurality of field emission sources and a complementary code modulo of said second plurality of field emission sources, said code defining a peak spatial force corresponding to substantial alignment of said code modulo of said first plurality of field emission sources with said complementary code modulo of said second plurality of field emission sources, said code also defining a plurality of off peak spatial forces corresponding to a plurality of different misalignments of said code modulo of said first plurality of field emission sources and said complementary code modulo of said second plurality of field emission sources, said plurality of off peak spatial forces having a largest off peak spatial force, said largest off peak spatial force being less than half of said peak spatial force. - View Dependent Claims (19, 20)
