Abstract: A system and method for detection of a malfunction in an elevator. The system includes an elevator cab, a server, at least one sensor, and a controller. The controller receives a signal captured by the at least sensor and transmit to the server. The server processes the transmitted signal and prognostically detects the malfunction in the elevator cab.

Abstract: A mechanical hoistway access control device for an elevator landing door includes a first and a second base plates mounted on the hoistway side of a landing door panel and arranged in parallel with one another, a slider slidably arranged between the first and second base plates and configured to move in conjunction with a car door and configured to protrude out from a door closing side end of the landing door by a first elastic member to take an extended position when the landing door is opened with no elevator car at the landing, and a latch attached to the landing door and configured to engage with the slider to keep the slider in the extended position once the slider protrudes out from the door closing side end of the landing door.

Abstract: An emergency operation controller for an elevator is connected to other emergency operation controllers of their respective elevators through network, and each controller constitutes a node in the network. The controller generates and transmits an emergency condition detection message to other controllers in the network which constitute adjacent nodes to the controller when the controller detects an emergency condition, and receives an emergency condition detection message from other controllers which constitute adjacent nodes to the controller in the network when other controllers detect an emergency condition. The emergency condition detection message includes a propagation count. The propagation count is configured to be decremented by one, each time one controller transmits the emergency condition detection message to other controllers which constitute next adjacent nodes. The emergency condition detection message is continuously transmitted until the propagation count reaches to zero.

Abstract: An elevator rope guide system comprises a plurality of rope guides for restricting the swaying of at least one main rope and a plurality of stop mechanisms each configured to stop a corresponding rope guide. The rope guides are located above an elevator car and/or counterweight and are vertically movable along a hoistway. The stop mechanisms are positioned at different intermediate heights along the hoistway. The elevator rope guides are collected by the elevator car or counterweight as the elevator car or counterweight moves up and are stopped by a corresponding stop mechanism as the elevator car or counterweight moves down.

Abstract: A mechanical hoistway access control device for an elevator landing door includes a first blocking member mounted on a position on a landing door frame above a landing door, and a second blocking member mounted on a position on a car door frame above a car door. The first blocking member is pivotably attached between an upright position and a first horizontal position extending in the door opening direction about a horizontal shaft. The second blocking member is pivotably attached between an upright position and a second horizontal position about a horizontal shaft, the second horizontal position being where the second blocking member protrudes out to the landing door side to block movement of the first blocking member.

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: A method for detecting trapped passengers in an elevator car (1) comprises collecting a sound in the elevator car (1) when an elevator controller (2) detects any failure of an elevator and comparing the level of the sound a threshold level. The method further includes automatically making a call to a help desk (26) and taking pictures in the interior of the elevator car (1) when the level of the sound exceeds the threshold level.

Abstract: A sensor system for controlling operation of an escalator arranged on a landing plate at the exit of the escalator includes a plurality of sensors arranged over a landing area of the landing plate. Each sensor is disposed at predetermined intervals with respect to the width direction along the width between two balustrades and the length direction along the moving direction of the escalator, and is configured to detect a predetermined pressure so as to obtain a transition of ON/OFF states in response to a load presence.
