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 slide lock mechanism, comprising:

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

a second magnetic field emission structure associated with a second object, said second field emission structure having a second plurality of magnetic field emission sources having positions and polarities in accordance with a second code, said second code being complementary to said first code, said second magnetic field emission structure including a first portion corresponding to a second code modulo of said second code and a second portion corresponding to a first partial code modulo of said second code, said first partial code modulo not including one of a first part of said second code modulo or a last part of said second code modulo; and

a sliding mechanism associated with said second object, said sliding mechanism enabling said first magnetic field emission structure to be moved across said second magnetic field emission structure to a locked position where said first magnetic field emission structure is substantially aligned with said first portion of said second magnetic field emission structure and a peak attractive spatial force is produced, said first object being attached to said second object while said first magnetic field emission structure is in said locked position, said sliding mechanism also enabling said first magnetic field emission structure to be moved across said second magnetic field emission structure to an unlocked position where said first magnetic field emission structure at least partially overlaps said second portion of said second magnetic field emission structure producing a repel force causing said second object to be detached from said first object while said first magnetic field emission structure is in said unlocked position.

2. 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.

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

4. The system of claim 1, where said first code and said second code are at least one of one-dimensional codes, two-dimensional code, three-dimensional codes, or four-dimensional codes.

5. The system of claim 1, wherein said first partial code modulo succeeds said second code modulo.

6. The system of claim 1, wherein said first partial code modulo precedes said second code modulo.

7. The system of claim 6, wherein a second partial code modulo of said second code succeeds said second code modulo.

8. The system of claim 1, wherein said first code and said second code have at least two dimensions and said second magnetic field emission structure has a left side, a right side, a top side, and a bottom side, and said first partial code modulo is alongside one of said left side, said right side, said top side, or said bottom side, and a second partial code modulo is alongside a remaining one of said left side, said right side, said top side, or said bottom side which said first partial code modulo is not alongside.

9. The system of claim 1, wherein one of said first object or said object is a drawer.

10. The system of claim 1, wherein magnetic field strengths of said second polarity of magnetic field emission sources are configured such that said repel force increases as said first magnetic field emission structure is moved further away from said locked position.

11. The system of claim 1, wherein at least one field emission source of said second magnetic field emission structure comprises an electromagnet.

12. The system of claim 11, wherein said at least one field emission source is controllable so as to effect movement of said first object relative to said second object.

13. A method for producing a slide lock mechanism, comprising:

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

associating a second magnetic field emission structure with a second object, said second field emission structure having a second plurality of magnetic field emission sources having positions and polarities in accordance with a second code, said second code being complementary to said first code, said second magnetic field emission structure including a first portion corresponding to a second code modulo of said second code and a second portion corresponding to a first partial code modulo of said second code, said first partial code modulo not including one of a first part of said second code modulo or a last part of said second code modulo; and

associating a sliding mechanism with said second object, said sliding mechanism enabling said first magnetic field emission structure to be moved across said second magnetic field emission structure to a locked position where said first magnetic field emission structure is substantially aligned with said first portion of said second magnetic field emission structure and a peak attractive spatial force is produced, said first object being attached to said second object while said first magnetic field emission structure is in said locked position, said sliding mechanism also enabling said first magnetic field emission structure to be moved across said second magnetic field emission structure to an unlocked position where said first magnetic field emission structure at least partially overlaps said second portion of said second magnetic field emission structure producing a repel force causing said second object to be detached from said first object while said first magnetic field emission structure is in said unlocked position.

14. The method of claim 13, 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.
