Abstract: In some embodiments, a tool-matching system includes a first controller and a plurality of second controllers. Each of the second controllers is configured to support a digital twin and control configuration parameters of the corresponding measuring instrument. The first controller is configured to estimate configuration-parameter changes for the measuring instruments based on instrument drift data. The estimated parameter changes are directed at tool matching the measuring instruments at a future time. The first controller is also configured to receive a plurality of reports evaluating the estimated configuration-parameter changes. Each of the reports is generated with the respective digital twin based on a respective subset of the estimated configuration-parameter changes.

Abstract: Footrest assembly for a passenger seat having a saddle (22) and a post (16) pivotally coupled to a fastener (38) connected to the saddle. A ratcheting mechanism (86) with at least one tooth (88) is positioned on a first end (20) of the post and a pawl (90) is pivotally coupled to a pawl shaft (98) fixedly coupled to the saddle. A cam follower (96) is pivotally coupled to the fastener and positioned within a slot (106) formed in the end of the post in order to prevent the pawl from engaging with a tooth while pivoting in a direction of a fully deployed position of the assembly.
