Abstract: The devices and methods described herein may be used to restore left ventricular function to address mitral valve regurgitation. One variation of an implant comprises a plurality of tethered anchors and a plurality of force-distribution members slidably disposed on the tether between the anchors. One or more of the force-distribution members can comprise a bioabsorbable material.

Abstract: A row vision system modifies automated operation of a vehicle based on edges detected between surfaces in the environment in which the vehicle travels. The vehicle may be a farming vehicle (e.g., a tractor) that operates using automated steering to perform farming operations that track an edge formed by a row of field work completed next to the unworked field area. A row vision system may access images of the field ahead of the tractor and apply models that identify surface types and detect edges between the identified surfaces (e.g., between worked and unworked ground). Using the detected edges, the system determines navigation instructions that modify the automated steering (e.g., direction) to minimize the error between current and desired headings of the vehicle, enabling the tractor to track the row of crops, edge of field, or edge of field work completed.

Abstract: A pressure-testing system for a tubular product such as production tubing. The pressure testing system includes a controller; a fluid reservoir containing a test fluid; a pump in fluid communication with the fluid reservoir; a fluid hose having a first end configured to receive the test fluid from the reservoir, and a second end configured to be fluidically connected to a hydrotest tool for the tubular product; and a transducer.
