Abstract: A mobile-based equipment service system includes a remote server, a mobile device, and at least one equipment controller. The mobile device includes a user interface, and is configured to send a user authentication message, initiated by a user via the user interface, to the remote server. The remote server is configured to verify the user via the user authentication message and once verified, send an encrypted blob to the mobile device in response to the user authentication message. At least one equipment controller is configured to receive and decrypt the encrypted blob from the mobile device.

Abstract: Embodiments are directed to determining that an elevator car of an elevator system is approaching a landing, obtaining, by a controller, a value for at least one parameter associated with the elevator system based on the determination that the elevator car is approaching the landing, determining that the elevator car arrives at the landing within a threshold distance, determining, by the controller, when to engage in at least one of a brake cycling operation and a power cycling operation based on the value for the at least one parameter and based on determining that the elevator car arrives at the landing within the threshold distance, and initiating the at least one of a brake cycling operation and a power cycling operation at a time corresponding to the determination of when to engage in the at least one of a brake cycling operation and a power cycling operation.

Abstract: An exemplary system includes a moveable mass. A load bearing member includes at least one electrically conductive tension member that supports a load associated with movement of the mass. An electrically conductive member is situated along a selected portion of a path of movement of the load bearing member. The electrically conductive member is not subject to a load on the tension member. A processor is configured to determine an electrical resistance of the tension member as an indicator of a condition of the tension member. The processor is configured to determine an electrical resistance of the electrically conductive member. The processor uses the determined electrical resistance of the electrically conductive member to compensate for any environmental influence on the determined electrical resistance of the tension member.

Abstract: A method of wear detection of a coated belt or rope includes measuring an initial electrical resistance of one or more cords, strands or wires of the coated belt or rope. The initial electrical resistance is calibrated by repeating the measuring of initial electrical resistance and populating a database with the measured initial electrical resistance values. A true initial resistance is determined from the population of initial electrical resistances and subsequent measured values of electrical resistance of the one or more cords, strands or wires of the coated belt or rope.
