Abstract: A method of operating a safety net system of an elevator system is provided. The method includes installing a sensor in an elevator pit of the elevator system and executing a learning phase of the sensor to verify successful installation of the sensor. The executing of the learning phase includes causing the sensor to sense physical characteristics of a portion of the elevator pit when the elevator pit is known to have certain physical characteristics to generate a background reading, comparing the background reading against a reading associated with known physical characteristics of the portion of the elevator pit and verifying the successful installation of the sensor based on results of the comparing.

Abstract: A safety net system is provided for an elevator system including an elevator pit and multiple points of ingress to the elevator pit. The safety net system includes multiple sensors arranged in multiple planes encompassing the multiple points of ingress to perform sensing and to generate data corresponding to sensing results and a processor coupled to the multiple sensors to analyze whether the data indicates a person entering the elevator pit and to take an action based on results of the analysis.

Abstract: An elevator system, having: a car that operates normal and inspection modes; a sensor assembly; a safety chain; wherein while in the normal mode, the sensor assembly: monitors in a first sensing mode to detect whether an object is within a first area, and then monitors in a second sensing mode that is more sensitive than the first sensing mode to again detect the object; and upon determining that the object is potentially human, the safety chain is opened; and while in the inspection mode, the sensor assembly: bypasses the first sensing mode and monitors in the second sensing mode to detect whether the object is located in the first area; and upon detecting that the object is located in the first area, the safety chain is opened.

Abstract: An escalator system is provided and includes a balustrade including a skirt with a brush, a moving step, which is drivable to move in a conveyance direction along the balustrade to form a step-skirt interface between ends of the brush of the skirt and a corresponding side of the moving step, and an entrapment monitoring and detection system. The entrapment monitoring and detection system includes a sensor and a processor. The sensor is disposed at the step-skirt interface and is configured to sense an object being present at the step-skirt interface. The processor is configured to determine whether the sensor senses the object being present at the step-skirt interface for a predetermined time.
