A computer-implemented method, system, and computer program product for predicting fatigue and injury risk for users, such as workers performing material handling operations, in real-time. Motions performed by a user, such as lifting, carrying, and manipulating objects, are captured in real-time, such as via camera-based optical devices, electromyography sensors, and inertia measurement units. Upon capturing motions performed by the user, such captured motions are utilized by a trained machine learning model to predict fatigue and injury risk to users. Such a prediction is made by the trained machine learning model by comparing the captured motions to predefined thresholds of range of motion constraints based on the biomechanical parameters of the user from a digital twin model of the user. Feedback may then be provided based on the predicted fatigue and injury risk of the user, such as in the form of video, audio, and / or haptic alerts.

The reconfigurable structure includes a material layer mounted to the plurality of linkages of each linkage assembly. The material layer maintains a constant length across a range of motion of each linkage assembly, thereby reducing or eliminating in-plane strain of the material layer across the range of motion. In an example, the reconfigurable structure can provide a first configuration corresponding to an annular tube shape for a fluid vessel, conduit, or other suitable structure, and a second configuration corresponding to a flattened shape. The flattened shape of the second configuration can be used for storage and transport of the reconfigurable structure.

This disclosure relates generally to real time analysis of range of motion (ROM), wherein ROM is a measurement of movement around a specific joint or body part. The existing techniques for ROM fail for measurements made in certain planes and are not very effective for ROM measurements for extremely slow and very fast movements.

The received data is corrected for bias and processed at real time to analyze the ROM by computing range of motion (ROM) of a joint and a set of ROM parameters.
