Abstract: A safety net system is provided for an elevator system that includes an elevator pit. The safety net system includes a sensor and a processor. The sensor is arranged in a plane along a bottom of the elevator pit and is configured to perform sensing to sense an object disposed along the plane and to generate data corresponding to results of the sensing. The processor is operably coupled to the sensor and is configured to analyze the data and to determine whether the data is indicative of a person in the elevator pit based on analysis results.

Abstract: An illustrative example embodiment of a device for controlling movement of an elevator car includes an emergency stopping supervisor, such as a processor and memory associated with the processor. The emergency stopping supervisor is configured to: determine when an indication from an electrical protection device indicates that the elevator car should be stopped, issue a command for the elevator car to move at a reduced speed, monitor continued movement of the elevator car at the reduced speed, and continue to allow the elevator car to move at the reduced speed until a selected condition exists or immediately cause the elevator car to stop if the reduced speed is not within a predetermined range.

Abstract: An elevator system includes an elevator car, a pressure sensor, and a controller. The car is adapted to move vertically within a hoistway and defines a passenger compartment adapted to be occupied by at least one passenger. The sensor is configured to measure air pressure in the passenger compartment. The controller is configured to control travel of the elevator car, receive a plurality of pressure signals from the sensor indicative of changing air pressure in the passenger compartment over a prescribed time period, and execute a preprogrammed application configured to apply a current car velocity and the changing air pressure to a preprogrammed ear pressure table. Upon application, the controller outputs a command to reduce the current car velocity if application of the preprogrammed ear pressure table determines a differential ear pressure would otherwise exceed a preprogrammed threshold.
