A method for object detection within an elevator car including: transmitting radar signals at a selected polarization into an elevator car towards an individual; receiving reflected radar signals at a reflected polarization; comparing the reflected polarization to the selected polarization; determining that the individual is in possession of a metal object in response to comparing the reflected polarization to the selected polarization; and activating an alert in response to the determining that the individual is in possession of the metal object.

A safety device for controlling safety-relevant functions in an elevator system is configured, on the basis of input signals from at least one first component of the elevator system which provides information regarding current conditions within the elevator system, for example a current position and speed of a car, not only to control at least one second component, such as a brake, of the elevator system such that an unintended travel movement of the car is prevented. The safety device also controls at least one third component, such as a door drive, of the elevator system such that an unintended movement of a car door is prevented. In the safety device, both a UCM (unintended car movement) function and a UDM (unintended door movement) function are thus implemented.

A controller for a lifting platform and a lifting platform are provided. The lifting platform includes a lateral beam and actuators, two actuators being provided and respectively disposed at two ends of the lateral beam. The controller includes a control box and a circuit board provided in the control box. The circuit board is connected with the actuators via wires, and a backside of the control box is connected to the lateral bean. Openings facilitating connection between the wire and the circuit board are arranged on the control box, and at least one of the openings is provided at a frontside of the control box.

Disclosed is an elevator system for a multilevel architectural structure, the system having: a system controller, an elevator and an elevator controller, wherein the system controller and elevator controller communicate over a network, multi-level hoistway in which the elevator travels, the multi-level hoistway including a plurality of egress levels, including a first egress level, the first level being a primary egress level, wherein during an alarm condition the system, when the primary level is inaccessible, performs an emergency assessment of identifying a safe level of the plurality of levels at which to discharge passengers, the assessment comprising obtaining a smoke density profile for the egress levels, the profile illustrating a distribution of smoke within the multilevel structure, analyzing the smoke density profile, identifying a safe level having a smoke density that is safe, and instructing the elevator to discharge passengers on the safe level.

A door sensor unit, for determining a type of a door to which the door sensor unit is attached, is configured to: obtain movement data representing movement of the door during a learning period, and determine the type of the door based on the obtained movement data. A method for determining a type of a door is also disclosed.

A system and a method for operating one or more dynamic stoppers in an elevator car. A method includes receiving a command at one or more control panels to switch one or more dynamic stoppers from a first position to a second position. The one or more dynamic stoppers are installed on a platform of an elevator car. The elevator car includes one or more doors and the one or more control panels is installed in the elevator car. The method includes switching the one or more dynamic stoppers from the first position to the second position using one or more actuators coupled to the one or more dynamic stoppers, respectively.

A door operating arrangement in an elevator, including a door operating unit located in the elevator car including a door controller and a door drive as well as a door motor configured to open and close elevator car doors, optionally together with elevator landing doors, a DC bus connecting the door operating unit via a travelling cable of the elevator car with a DC power source of the elevator. The voltage level of the DC bus is between 40 V and 120 V, the DC bus is connected to a capacitor bank located in the elevator car having a parallel connection of at least two capacitors and a total capacity value of at least 75.000 μF, preferably at least 100.000 μF.

Disclosed is a system for an elevator door of an elevator car, wherein a controller controls the elevator door to travel in a proximate direction when closing and travel in a distal direction when opening, the system including: a panel that forms an exterior surface of an elevator door, the panel including a front surface extending in a widthwise direction between a proximate end and an opposing distal end to form a front surface of the elevator door, the panel including a proximate end surface extending in a depthwise direction to form a proximate end surface of the elevator door, the proximate end surface of the panel comprising a resilient portion that is capable of engaging a sensor in the panel when the elevator door is closing, and thereafter the controller instructs the elevator door to reopen.

An elevator car includes at least one elevator door, a door drive for actuating the elevator door, a sensor for detecting the motor power of the door drive and an evaluating unit that determines, based on the motor power detected, whether there is a deviation in the drive force actuating the elevator door from a reference drive force. The evaluating unit determines whether a deviation occurs due to an obstacle in contact with the elevator door or due to altered external conditions, particularly due to altered pressure conditions and/or air flow.

A locking system that locks and unlocks a door of an elevator car travelling along a track having stopping points and associated stopping point zones includes a lock mechanism having a locking position wherein the door is immobilized in a closed position and an unlocking position wherein the door can be opened, an actuator for bringing the lock mechanism into the locking and unlocking positions, and a control device activating the actuator to bring the lock mechanism into the unlocking position when the car is located in the region of a stopping point zone. A position detecting unit continuously detects the position of the car relative to the track and communicates the position to the control device that continuously detects whether the car is located in the region of a stopping point zone by comparing the communicated car position to stored position limit values of the stopping point zones.
