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: 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.
