Abstract: A guidance mechanism for an elevator car is constructed and arranged to move along a lane defined at least in-part between two opposing first and second lane structures of a stationary structure. The guidance mechanism includes a first support structure supported by the first lane structure. The first support structure includes a first retainer face disposed between the elevator car and the first lane structure that substantially faces the first lane structure, and is spaced from the first lane structure. A first retention device of the mechanism is disposed, at least in part, between the first retainer face and the first lane structure. The first retention device is supported by the elevator car and is constructed and arranged to contact the first retainer face for limiting lateral movement of the elevator car away from the first lane structure and toward the second lane structure.

Abstract: A monitoring device (20, 22), which is configured for monitoring movement of at least one component (6, 12) of an elevator system (2), includes an acceleration sensor (24) and a controller (26). The acceleration sensor (24) is configured for detecting accelerations (g, g′) of the at least one component (6, 12) and providing a corresponding acceleration signal (28, 30). The controller (26) is configured for determining peaks (28a, 28b, 30a, 30b) having positive or negative signs in the detected acceleration signal (28, 30); determining the signs of the detected peaks (28a, 28b, 30a, 30b); and determining that the moving direction of the at least one component (6, 12) has changed when two subsequent peaks (28a, 28b, 30a, 30b) of the acceleration signal (28, 30) having the same sign are detected.

Abstract: Embodiments include a system and method for controlling doors in a multi-door system. Embodiments a controller configured to control the multi-door system, wherein the multi-door system includes a first door and a second door, wherein the first door is on a different side than the second door, and one or more sensors operably coupled to the multi-door system and the controller, wherein the one or more sensors are configured to detect one or more conditions. The controller includes a processor, wherein the processor is configured to receive an input from the one or more sensors, wherein the input comprises at least one of call information and crowd sensing information, responsive to the input, prioritize an operation of the first door and the second door based at least in part on the input, and operate the first door and second door based on the prioritization.

Abstract: A ropeless elevator system includes a vertically extending first lane, a vertically extending second lane, and a transfer station extending between and in communication with the first and second lanes. An elevator car is disposed in and is constructed and arranged to move through the transfer station and the first and second lanes. A propulsion system of the elevator system propels the elevator car through at least the first and second lanes and carries a supplemental DC energy storage device for providing supplemental energy to the elevator car during normal operation. A wireless power transfer system of the elevator system is configured to periodically charge the DC energy storage device.
