    Abstract: An elevator motion alert system is configured to alert a person of an object moving in at least one hoistway of an elevator system. The elevator motion alert system includes a sensor configured to detect object motion. A transmitter of the elevator motion alert system is carried by the object and is configured to transmit a pressure wave at a pre-defined frequency upon movement of the object. An electronic device of the elevator motion alert system is configured to receive and process the pressure wave for alerting the person of object movement.

    Abstract: The present invention relates to braking torque detection for an elevator brake and belongs to the technical field of elevators. A braking torque detection method for an elevator brake according to the present invention comprises the following steps: a drive motor outputting a first detection torque for a first brake torque inspection; the drive motor stopping output of the detection torque in intermittent time periods when it is determined that a second brake torque inspection is required according to a result of the first brake torque inspection; and the drive motor outputting a second detection torque for the second brake torque inspection. The present invention can avoid overheating of a frequency converter in a continuous braking torque detection process and achieves good braking torque detection accuracy.
