Abstract: Disclosed herein is a method of detecting a microsleep event in a subject. The method includes determining a number of eye openness factors by measuring a number of distances between an upper eyelid and a lower eyelid of at least one eye over a time period. Graphical representations of the eye openness factors are then generated. Changes in the eye openness factors over the time period are correlated with a reference eye closure pattern indicative of the microsleep event. Also disclosed is a microsleep event detection device.

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.
