ROTARY POSITION INDICATOR FOR ACTUATOR
First Claim
Patent Images
1. A system, comprising:
- a rotary position indicator configured to integrate with an actuator, wherein the rotary position indicator comprises;
a first shaft and a second shaft in a nested arrangement, wherein the first and second shafts are configured to transfer linear motion of an actuation component of the actuator into a first rotational motion; and
a gear box configured to couple to the actuator, wherein the gear box is configured to transfer the first rotational motion to a second rotational motion of a position shaft.
