Abstract: A rope sway detection system of an elevator system includes a magnetic pickup located adjacent to a suspension member of an elevator system. The magnetic pickup is configured to detect a movement of the suspension member via a change in a magnetic field at the magnetic pickup. A signal processing unit is operably connected to the magnetic pickup. The signal processing unit is configured to determine a maximum amplitude of a sway of the suspension member based on the change in the magnetic field, compare the maximum amplitude to a preselected threshold, and signal a change in operation of the elevator system based on an actual or predicted exceedance of the threshold.

Abstract: The present invention comprises a retention strap device which retains a tool or object in the vicinity of the user. The invention comprises an elastic cord formed into a loop, with both ends of the cord terminating in a terminal clip. Disposed along the cord, are first and second slide stops, which allow the user to place and cinch a loop around the tool for securely retaining the tool and to place and cinch a second loop around the wrist of the user or other attachment position on or near the user's person.
