Abstract: An illustrative example embodiment of an elevator system includes an elevator car situated for movement among a plurality of landings. The elevator car includes a car door and a door mover. A door interlock associated with a landing door at each of the landings is configured to couple the associated landing door with the car door. The door interlocks respectively include a lock switch. A controller is configured to: cause the elevator car to move to at least one of the landings; when the elevator car is at the at least one landing, cause the door mover to instigate movement of the door interlock sufficient to at least temporarily change a position of the lock switch; and locate a malfunctioning one of the lock switches at one of the landings based on the movement of the door interlock.

Abstract: Disclosed is a fixture plate comprising a back plate defined by a member extending in a widthwise (W) direction and a height-wise (H) direction, a plurality of support arms including a first support arm and a second support arm connecting proximate a bottom edge of the back plate and spaced in the widthwise direction by a distance W1, each of the plurality of support arms comprising a compound profile defining a pivot section and a support section the pivot section extending arcuately downward along the height-wise direction to a first distal end, the support section comprising a first portion forming a support base, the support base extending perpendicularly away from the back plate to a second distal end, and a second portion that forms a hook portion, the hook portion extending upwardly along the height-wise direction to a third distal end to from a free end of the support section.

Abstract: A method for automating maintenance of a conveyance system includes performing automated maintenance tasks on the conveyance system; storing results of the automated maintenance tasks in a maintenance database; and providing maintenance tasks to the mobile device, each maintenance task including a maintenance task identifier and a maintenance task status.

Abstract: A power architecture includes a panel receiving power from a power grid through a breaker, a power supply coupled to the breaker to receive power from the grid, a battery coupled to the power supply through a switch, an elevator motor controller coupled to the power supply, the power supply providing power from at least one of the grid and the battery to the controller, and a charger coupled to the breaker and the battery and configured to receive power from the power grid and provide power to the battery to charge the battery.

Abstract: An elevator safety system including a controller, and a hoistway safety node arranged at a pit portion of an elevator hoistway. The hoistway node is operatively connected to one of a pit safety device and a lower hoistway device arranged at the elevator pit. A first bus links the hoistway node and the controller. The first bus passes communication signals directly from the hoistway node to the controller. A car node is arranged in an elevator car. The car node is operatively connected to a car safety device arranged at the elevator car. A second bus links the car node and the controller. The second bus passes communication signals directly from the car node to the controller.

Abstract: A system for monitoring elevator car travel includes a plurality of bi-stable sensors (12) traveling with an elevator car (10); a plurality of sense elements (20) positioned along a path of the sensors (12); the sense elements (20) causing the sensors (12) to assume one of a first state and a second state; wherein states of the sensors (12) define a zone code (30) identifying a zone corresponding to the elevator car (10) position, the zone code (30) being a gray code.
