Abstract

An improved field emission system and method is provided that involves field emission structures having electric or magnetic field sources. The magnitudes, polarities, and positions of the magnetic or electric field sources are configured to have desirable correlation properties, which may be in accordance with a code. The correlation properties correspond to a desired spatial force function where spatial forces between field emission structures correspond to relative alignment, separation distance, and the spatial force function.

Claims

1. A system for producing a surface above which an object will hover, comprising:

a first magnetic field emission structure associated with said surface, said first field emission structure having a first plurality of magnetic field emission sources having positions and polarities in accordance with a first code combination including a first partial code modulo of a first code and a successive second partial code modulo of said first code, said first code combination corresponding to two code modulos of said first code repeating in a first direction, said first code being complementary to a second code corresponding to a second magnetic field emission structure associated with said object, said second field emission structure having a second plurality of magnetic field emission sources having positions and polarities in accordance with a code modulo of said second code; and

a hover channel corresponding to the outer boundary of said first magnetic field emission structure, said second field emission structure being able to move within said hover channel across all of said first magnetic field emission structure whereby said first magnetic field emission structure and said second field emission structure produce a repel force causing said object to hover above said surface.

2. The system of claim 1, wherein said first code and said second code are two-dimensional codes.

3. The system of claim 1, wherein said first code and said second code are in accordance with at least one of a Barker code, a Gold code, a Kasami sequence, a hyperbolic congruential code, a quadratic congruential code, a linear congruential code, a Welch-Costas array code, a Golumb-Costas array code, a pseudorandom code, a chaotic code, an Optimal Golomb Ruler code, a deterministic code, or a designed code.

4. The system of claim 1, wherein said first code and said second code are in accordance with a desired spatial force function.

5. The system of claim 1, wherein said first magnetic field structure is produced using a first plurality of electromagnets.

6. The system of claim 5, further comprising:

a control system to control the polarities and magnetic field strengths of said first plurality of electromagnets.

7. The system of claim 6, wherein said polarities and magnetic field strengths of said first plurality of electromagnets are controlled to control the movement of said object.

8. The system of claim 1, wherein said positions and polarities of said first plurality of magnetic field emission sources are also in accordance with a second code combination including a third partial code modulo of said first code successive with a portion of said first code combination, said third partial code modulo and said portion of said first code combination corresponding to two code modulos of said first code repeating in a second direction, said second direction being perpendicular to said first direction.

9. The system of claim 8, wherein said second code combination includes one of said second partial code modulo of said first code or said second partial code modulo of said second code.

10. The system of claim 9, wherein said positions and polarities of said first plurality of magnetic field emission sources are also in accordance with a third code combination including a fourth partial code modulo of said first code successive with a portion of said second code combination, said fourth partial code modulo and said portion of said second code combination corresponding to two code modulos of said first code repeating in said first direction.

11. A method for producing a surface above which an object will hover, comprising the steps of:

associating a first magnetic field emission structure with said surface, said first field emission structure having a first plurality of magnetic field emission sources having positions and polarities in accordance with a first code combination including a first partial code modulo of a first code and a successive second partial code modulo of said first code, said first code combination corresponding to two code modulos of said first code repeating in a first direction;

associating a second magnetic field emission structure associated with said object, said second field emission structure having a second plurality of magnetic field emission sources having positions and polarities in accordance with a code modulo of a second code, said second code being complementary to said first code; and

providing a hover channel corresponding to the outer boundary of said first magnetic field emission structure, said second field emission structure being able to move within said hover channel across all of said first magnetic field emission structure whereby said first magnetic field emission structure and said second field emission structure produce a repel force causing said object to hover above said surface.
