US Patent:

20230008973, Jan 12, 2023

Filed:

Mar 2, 2022

Appl. No.:

17/684801

Inventors:

- Weston FL, US
Philip Robert Woods - Kalamazoo MI, US
Cory J. Welch - Kalamazoo MI, US
Mark A. Wasserman - Delton MI, US

Assignee:

MAKO Surgical Corp. - Weston FL

International Classification:

B25J 9/16
B25J 9/00
B25J 19/02
B25J 13/02

Abstract:

A sensor system includes a first member that extends along a rotational axis and has a surface disposed circumferentially about the rotational axis. A conductive element is disposed on the surface of the first member and disposed about the rotational axis. A second member extends along the rotational axis. A rotational position between the first member and the second member is adjustable. A target is mounted to and rotatable with the second member and is movable relative to the second member between first and second positions. The target is spaced apart from the conductive element in both the first and second positions and is spaced further from the conductive element in the second position compared to the first position. The conductive element detects a change in movement of the target from the first position to the second position for any rotational position between the first member and the second member.

B25J 9/00

Abstract:

A sensor system includes a first member extending along a rotational axis and having a surface disposed circumferentially about the axis. The sensor system further includes a conductive element fixed to the first member and disposed on the surface and about the rotational axis and a second member extending along the axis. A rotational position between the first member and the second member is adjustable. The sensor system further includes a target mounted to and rotatable with the second member and being movable relative to the second member between first and second positions. The target is spaced apart from the conductive element in both the first and second positions and is closer to the conductive element in the second position compared to the first position. The conductive element is configured to sense the target in the second position for any rotational position between the first member and the second member.
