Abstract: An elevator system includes a hoistway, an elevator car configured to travel in the hoistway, and a pit located at a bottom of the hoistway. A safety chain is configured to enable or disable motion of the elevator car, and a sensor assembly is configured to initiate opening the safety chain to disable motion of the elevator car upon detection of a person in a detection region of the sensor assembly in the hoistway. A test device is configured to test operation of the sensor assembly to detect malfunctioning and/or tampering of operation of the sensor assembly.

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 elevator sensor device includes at least one sensor supported on a door of an elevator car. The sensor provides an output including an indication of at least movement of the door along at least one axis and movement of the elevator car along at least one axis. A processor associated with the at least one sensor receives the output and determines at least one characteristic of the movement of the door based on the indication of the movement of the door. The processor also determines a location of the elevator car where the movement of the door occurs based on the indication of movement of the elevator car.

Abstract: A method of monitoring a conveyance system is provided. The method including: monitoring vibratory signatures along a first axis of a conveyance apparatus of a conveyance system; detecting a vibratory signature along the first axis about equivalent to a vibratory signature of significant event; and examining vibratory signatures for a secondary event along at least one of the first axis and a second axis of the conveyance apparatus for at least one of a selected time period after detection of the significant event and a selected time period before detection of the significant event.

Abstract: According to an aspect, a method includes monitoring a plurality of vibration data by a vibration monitoring beacon and determining that the vibration monitoring beacon has been installed at a service location based on detecting an installation characteristic signature in the vibration data. The vibration monitoring beacon can transition into a learning mode based on determining that the vibration monitoring beacon has been installed at the service location. The method can also include monitoring for a learning mode termination event and transitioning the vibration monitoring beacon from the learning mode to a normal operation mode based on detecting the learning mode termination event.

Abstract: A system to determine a location of a signal emitting device is provided. First, second, and third data is received from at least one movable communication device. Each of the first, second, and third data include a unique identifier of the signal emitting device, a signal strength of a signal received by the at least one movable communication device from the signal emitting device, and a location of the at least one movable communication device when it received the signal. Each of the first, second, and third data include different locations of the at least one movable communication device. A location of the signal emitting device is computed based at least in part on the received first, second, and third data.

Abstract: A method for monitoring thresholds for performance attributes in an elevator system is provided. Aspects includes collecting, by a sensor affixed to an elevator car, sensor data associated with the elevator system wherein the sensor data comprises one or more performance attribute values for a set of performance attributes of the elevator system. Obtaining a threshold profile associated with the elevator system, wherein the threshold profile comprises thresholds for each performance attribute in the set of performance attributes of the elevator system. Comparing the one or more performance attribute values to corresponding thresholds for the set of performance attributes and transmitting an alert for any of the one or more performance attribute values exceeding the corresponding thresholds for the set of performance attributes.
