    Abstract: An illustrative example embodiment of an elevator rope sway damping assembly includes a plurality of sway dampers having a width and a length. An actuator device selectively causes movement of the sway dampers in a direction transverse to the length between a first position where the sway dampers are spaced apart by a first distance and a second, sway-damping position where the sway dampers are spaced apart by a second, shorter distance. The actuator device provides an indication when the sway dampers are in the first position.

    Abstract: An illustrative example embodiment of an elevator cab air purification device includes a housing having an inlet, an outlet, and at least one air pathway between the inlet and the outlet. A fan module is situated to cause air flow into the housing through the inlet, through the housing, and out of the housing through the outlet. The air flow through the housing includes air flow along the at least one pathway in at least a first direction. An air purifier is situated within the housing and configured to purify air that flows along the at least one pathway before the air exits the housing through the outlet.

    Abstract: An illustrative example embodiment of an elevator cab ventilation device includes a fan module and a ventilation controller that is configured to control operation of the fan module based on an indication of a position of at least one door of the elevator cab. The controller is configured to control the fan module to operate in a first mode to move a first amount of air per unit time when the door is in a first open position. The controller is configured to control the fan module to operate in a second mode to move a second, larger amount of air per unit time when the door is in a second, different open position.
