Abstract: Embodiments assess cumulative ergonomic risk. An embodiment includes receiving risk data where the risk data may include, for each task of a plurality of tasks performed by an operator, an indication of an ergonomic risk level, of a plurality of ergonomic risk levels, for the operator performing the task. Such an embodiment continues by restructuring the risk data received to determine, across the plurality of tasks, a total time duration for each joint of a plurality of joints of the operator, at each risk level. Thereafter, the embodiment determines the cumulative ergonomic risk based on the total time duration for each joint at each risk level.

Abstract: Embodiments provide functionality to assess dynamic ergonomic risk. One such example embodiment receives process planning data for an operator performing a task. Based on the received process planning data, parameters for a time analysis are defined and a time analysis of the operator performing the task is performed using the defined parameters. In turn, static ergonomic risk is determined based on the received process planning data. Then, an indication of dynamic ergonomic risk is provided based on (i) results of performing the time analysis and (ii) the determined static ergonomic risk.

Abstract: Embodiments assess ergonomic risk of causing harm to a worker in a workplace. One such embodiment receives an indication of posture risk level for each of a plurality of digital human models performing a task. In turn, a weighted average of the received indications of posture risk level is determined. This determined weighted average is indicative of ergonomic risk to a real-world worker performing the task in a workplace. Embodiments consider consecutive risk through modifications to weights used in the determining the weighted average.

Abstract: Embodiments assess ergonomic risk in environments, such as factories and workstations. One such embodiment begins by receiving process planning data for an operator performing a task. In turn, the received process planning data is used to generate a posture for the operator to perform the task in a certain real-world environment. The generated posture is processed using a hierarchical decision tree to determine ergonomic risk of the posture in the certain real-world environment. Output includes an indication of the determined ergonomic risk.

Abstract: A rigid insulating panel comprising an insulating material core with an R-value of at least 2.5 (hr·ft2·° F.)/BTU·in. The insulating material core has opposed first and second surfaces, a pair of spaced-apart longitudinal edges, and a pair of spaced-apart lateral edges extending between the pair of longitudinal edges. At least one of the pair of longitudinal edges and the pair of lateral edges comprises connecting members including a tongue and groove assembly with an inner groove and an outer tongue separated by a substantially S-shaped median wall. The tongue and groove assembly is engageable with the tongue and groove assembly of an adjacent insulating panel to provide a flexible interconnection therebetween. The rigid insulating panel also comprises at least one membrane covering one of the first surface and the second surface. An assembly method for insulating a concrete surface of a building using an assembly of insulating panels is also provided.

Abstract: The present document describes a user-operated tool and a method for lifting and dragging a heavy load on a surface. The tool comprises an elongated body having an upper end comprising a grip, a lower end for making contact with the surface in the vicinity of the heavy load, and a flex point located between the upper end and the lower end. The tool comprising a lift and drag member, having a hook member for hooking to the heavy load, connected to the elongated body and is movable about the flex point. The tool comprising a strap reel fixed on the elongated body for winding the strap thereon. In use, the user grips the tool and rotates the elongated member about the lower end and away from the heavy load. The lift and drag member thereby first lifts and then drags the heavy load toward the lower end.
