Abstract: There is provided fall protection equipment, such as a self-retracting lifeline (SRL), including features that enable the SRL to determine a worker's location and a map of a surface on which the worker is working. There is also provided an SRL having a lifeline with a distal end for connection to a user, at least one sensor adapted to determine the tension in the lifeline, and a computing device comprising a processor and a memory.

Abstract: An automated method for generating a final setup for orthodontic treatment. The method includes receiving a digital 3D model of teeth in an initial state. The method computes a scoring function based upon metrics related to the initial state to generate a corresponding score, perturbs the state of the teeth through translations and rotations of a tooth or set of teeth to generate a perturbed state of the teeth, and updates the state of the teeth based upon the score and the perturbed state of the teeth to generate one or more final setups representing a final state of the teeth after the orthodontic treatment.
