Abstract

Described is a device comprising a retro-reflective marker sphere comprising: a core ball comprising: a generally spherical body portion, a mounting base extending from one end of the body portion of the core ball, and a mounting recess having a recess opening in the mounting base and extending into the body portion of the core ball, and a retro-reflective covering on the core ball, the retro-reflective covering comprising an opening through which the mounting base of the core ball extends, wherein a flat lower surface of the mounting base is spaced proximally from a lower edge of the opening of the retro-reflective covering, and wherein the mounting recess includes an interior screw thread for engaging an exterior screw thread of a mounting post when the retro-reflective marker sphere is mounted on the mounting post.

Claims

1. A package comprising:

a pocket layer including one or more pockets for receiving one or more retro-reflective marker spheres,

one or more backing layers joined to the pocket layer by an adhesive, and

a retro-reflective marker sphere contained in the package,

wherein the adhesive has a peel strength of no greater than 22.24 N of force,

wherein the package comprises an upper backing layer joined to the pocket layer and a lower backing layer joined to the upper backing layer, and

wherein the upper backing layer comprises one or more first openings that are aligned with respective one or more second openings of the one or more pockets of the pocket layer.

2. The package of claim 1, wherein the package has only a single backing layer.

3. The package of claim 1, wherein the package comprises an upper backing layer joined to the pocket layer and a lower backing layer joined to the upper backing layer, and wherein the lower backing layer includes the mounting base opening.

4. The package of claim 3, wherein the upper backing layer comprises one or more first openings that are aligned with respective one or more second openings of the one or more pockets of the pocket layer.

5. The package of claim 1, wherein the adhesive has a peel strength of no greater than 13.34 N of force.

6. The package of claim 5, wherein the retro-reflective marker sphere comprises a mounting recess including one or more interior snap-on engagement structures for engaging one or more exterior snap-on engagement structures of a mounting post when the retro-reflective marker sphere is mounted on the mounting post.

7. The package of claim 1, wherein the retro-reflective marker sphere comprises a mounting recess including an interior screw thread for engaging an exterior screw thread of a mounting post when the retro-reflective marker sphere is mounted on the mounting post.

8. The package of claim 1, wherein the package has only a single backing layer.

9. The package of claim 1, wherein the package comprises an upper backing layer joined to the pocket layer and a lower backing layer joined to the upper backing layer.

10. The package of claim 9, wherein a lower backing includes the mounting base opening.

11. The package of claim 9, wherein the upper backing layer comprises one or more first openings that are aligned with respective one or more second openings of the one or more pockets of the pocket layer.

12. The package of claim 1, wherein the package comprises an upper backing layer joined to the pocket layer and a lower backing layer joined to the upper backing layer.
