Abstract

A headset includes an optical assembly, an adjustment assembly, and a measurement component. The measurement component is configured to measure an interpupillary distance provided by an adjustment assembly in a first direction and an eye relief distance provided by the adjustment assembly in a second direction, where the first direction is orthogonal to the second direction. The measurement component includes a first rheostat configured to measure the interpupillary distance and a second rheostat configured to measure the eye relief distance, wherein the second rheostat is placed parallel to the first rheostat. The measurement component further includes a linkage configured to translate a motion of the adjustment assembly in the second direction to the first direction.

First claim

What is claimed is:

1. A headset comprising:
an optical assembly associated with the headset, wherein the optical assembly comprises a first lens and a second lens spaced from the first lens by a first distance;
an adjustment assembly comprising:
an interpupillary distance adjustment mechanism configured to adjust the first distance between the first lens and the second lens in a first direction; and
an eye relief distance adjustment mechanism configured to adjust the optical assembly a second distance in a second direction that is orthogonal to the first direction; and

a measurement component configured to measure the first distance and the second distance via motion in the first direction, wherein the measurement component comprises a first rheostat configured to measure the first distance.

2. The headset of claim 1 , wherein the measurement component further comprises:
a second rheostat configured to measure the second distance, wherein the second rheostat is positioned parallel to the first rheostat.

3. The headset of claim 2 , wherein the first rheostat comprises a first slider and a first resistance track, wherein the first slider is attached to the optical assembly, wherein the first slider is configured to slide along a first resistance track;
wherein the second rheostat comprises a second slider and a second resistance track, wherein the second slider is coupled with a connection member, wherein the connection member is attached to the adjustment assembly, wherein the second slider is configured to slide along a second resistance track that is parallel to the first resistance track.

4. The headset of claim 3 , wherein the connection member comprises a linkage configured to translate a motion of the eye relief distance adjustment mechanism in the second direction to the first direction.

5. The headset of claim 1 , further comprising:
a housing; and
a mounting component attached to the housing, wherein the mounting component is coupled to the adjustment assembly.

6. The headset of claim 1 , further comprising:
a housing; and
a mounting component attached to the housing, wherein the mounting component is coupled to the measurement component.

7. The headset of claim 6 , wherein the measurement component comprises a linkage pivotably coupled to the mounting component and is configured to translate a motion of the adjustment assembly in the second direction to the first direction.

8. The headset of claim 1 , the interpupillary distance adjustment mechanism comprises:
a shaft;
a turnbuckle coupled with a first connection member and a second connection member,
wherein the first connection member is attached to a first lens holder of the optical assembly,
wherein the second connection member is attached to a second lens holder of the optical assembly, and
wherein the turnbuckle is configured to cause the first connection member and the second connection member to slide away from or closer to each other along the shaft.

9. The headset of claim 1 , wherein the eye relief distance adjustment mechanism comprises a slide system configured to move the optical assembly along the second direction to adjust the second distance.

10. The headset of claim 1 , wherein the optical assembly comprises:
a first lens holder configured to hold the first lens; and
a second lens holder configured to hold the second lens,
wherein each of the first lens holder and second lens holder comprises a cover plate configured to hold the respective lens.

11. A measurement component for measuring an interpupillary distance provided by an adjustment assembly in a first direction and an eye relief distance provided by the adjustment assembly in a second direction, wherein the first direction is orthogonal to the second direction, wherein the measurement component comprises:
a first rheostat configured to measure the interpupillary distance;
a second rheostat configured to measure the eye relief distance, wherein the second rheostat is placed parallel to the first rheostat; and
a linkage configured to translate a motion of the adjustment assembly in the second direction to the first direction.

12. The measurement component of claim 11 , further comprising a mounting component, wherein the mounting component is attached to a housing of a headset.

13. The measurement component of claim 12 , wherein the linkage is pivotally attached to the mounting component at a pivot point and configured to translate the motion of the adjustment assembly in the second direction to the first direction by pivoting about the pivot point.

14. The measurement component of claim 13 , wherein the linkage comprises a bell crank.

15. The measurement component of claim 11 , wherein the first rheostat comprises a first slider and a first resistance track, wherein the first slider is attached to an optical assembly, wherein the adjustment assembly is configured to adjust the interpupillary distance between a first lens of the optical assembly and a second lens of the optical assembly, wherein the first slider is configured to slide along a first resistance track to measure the interpupillary distance.

16. The measurement component of claim 15 , wherein the adjustment assembly comprises an interpupillary distance adjustment mechanism and an eye relief distance adjustment mechanism, wherein the interpupillary distance adjustment mechanism comprises:
a shaft;
a turnbuckle coupled with a first connection member and a second connection member,
wherein the first connection member is attached to a first lens holder of the optical assembly, wherein the second connection member is attached to a second lens holder of the optical assembly, and
wherein the turnbuckle is configured to cause the first connection member and the second connection member to slide away from or closer to each other along the shaft.

17. The measurement component of claim 15 , wherein the second rheostat comprises a second slider and a second resistance track, wherein the second slider is coupled with a connection member, wherein the connection member is attached to the adjustment assembly, wherein the adjustment assembly is configured to adjust an eye relief distance of an optical assembly in the second direction, wherein the second slider is configured to slide along a second resistance track to measure the eye relief distance.

18. The measurement component of claim 17 , wherein the adjustment assembly comprises an interpupillary distance adjustment mechanism and an eye relief distance adjustment mechanism, wherein the eye relief distance adjustment mechanism comprises a slide system configured to move the optical assembly along the second direction to adjust the eye relief distance.

19. The measurement component of claim 11 , wherein the adjustment assembly is coupled to an optical assembly, wherein the adjustment assembly comprises:
an interpupillary distance adjustment mechanism configured to adjust the interpupillary distance between a first lens of the optical assembly and a second lens of optical assembly in the first direction; and
an eye relief distance adjustment mechanism configured to adjust the optical assembly the eye relief distance in the second direction that is orthogonal to the first direction.

20. The measurement component of claim 19 , wherein the optical assembly comprises:
