Abstract

Claims (29)

1. A magnetizer, comprising:

a housing including a top face, a bottom face, and a plurality of side faces adjoining the top face and the bottom face, wherein:

the top face includes a first opening configured to receive a needle, the first opening having a first cross-sectional area; and

one of the plurality of side faces includes a second opening having a second cross-sectional area, the second cross-sectional area at least one third of the first cross-sectional area; and

one or more magnets positioned in an interior of the housing,

wherein:

the first opening is substantially circular,

the second opening is substantially ovaloid defining a width and a length longer than the width, and

the width is greater than a diameter of the first opening.

2. The magnetizer according to claim 1 , wherein the second opening is larger than the first opening.

3. The magnetizer according to claim 1 , wherein the one or more magnets are positioned so as not to be visible through the second opening.

4. The magnetizer according to claim 1 , wherein a shape of the first opening is different from a shape of the second opening.

5. The magnetizer according to claim 1 , wherein the one or more magnets are positioned on a face of the plurality of side faces adjacent to the one of the plurality of side faces including the second opening.

6. The magnetizer according to claim 1 , wherein the one or more magnets are disposed within at least one or more of the plurality of side faces.

7. The magnetizer according to claim 6 , wherein the one or more magnets are integrated into the at least one or more of the plurality of side faces.

8. The magnetizer according to claim 1 , wherein the one or more magnets comprises a first magnet positioned on a first face of the plurality of side faces and a second magnet positioned on a second face of the plurality of side faces.

9. The magnetizer according to claim 1 , wherein the first opening is formed at least in part by a curved conical tapering surface which extends from the top face toward the bottom face.

10. The magnetizer according to claim 1 , wherein the interior of the housing includes a substantially smooth surface.

11. A magnetizer system, comprising:

a needle;

a detection system to detect the needle; and

the magnetizer according to claim 1 .

12. The system according to claim 11 , wherein the second opening is larger than the first opening.

13. The system according to claim 11 , wherein the one or more magnets are positioned so as not to be visible through the second opening.

14. The system according to claim 11 , wherein a shape of the first opening is different from a shape of the second opening.

15. The system according to claim 11 , wherein the one or more magnets are positioned on a face of the plurality of side faces adjacent to the one of the plurality of side faces including the second opening.

16. The system according to claim 11 , wherein the one or more magnets are integrated into at least one or more of the plurality of side faces.

17. The system according to claim 11 , wherein the first opening is formed at least in part by a curved conical tapering surface which extends from the top face toward the bottom face.

18. The system according to claim 11 , wherein the interior of the housing includes a substantially smooth surface.
