Abstract: A method enables emergency unlocking of a car door of an elevator having a car movable within a shaft to a floor. The car door has an electrically activatable lock and the floor has a shaft door with an electrically activatable door lock. The car door lock has a first latch for locking a first car door leaf and an emergency unlocking mechanism. The shaft door lock can be accessed from the floor. An actuator is attached to the shaft door. The method includes the steps: the shaft door is unlocked from the floor by the shaft door lock being manually actuated; actuation of the shaft door lock moves the actuator from a first position to a second position; in the second position, the actuator actuates the emergency unlocking mechanism; and actuation of the emergency unlocking mechanism unlocks the car door lock to unlock the first car door leaf.

Abstract: A method for registering a user's request to provide contactless access to an elevator button panel includes: sensing, by a sensor associated with the elevator button panel, a motion of an object pointing towards the panel by the user; determining a distance of the object from the panel; comparing the distance with a distance threshold to determine whether the object is within the distance threshold indicating the user's request for activating a button on the panel; responding to the determination that the distance is within the distance threshold by determining a magnitude and a direction of a velocity of the object while in motion; and registering the user's request when the velocity magnitude of the object is greater than a threshold velocity magnitude, and the direction is a positive direction indicating the motion of the object towards the button the user intended to select.

Abstract: A suspension device has at least one brake for braking an elevator car relative to a stationary component of an elevator system, a brake holding assembly holding the brake on the elevator car, and a support means holding assembly holding a support means on the elevator car. The support means connects the elevator car to a counterweight of the elevator system. The brake holding assembly holds the brake against the elevator car such that the brake moves relative to the elevator car in a force direction produced by the brake. The support means holding assembly holds the support means against the elevator car such that the support means moves relative to the elevator car substantially in a force direction produced by the support means. A load measuring device measures an exerted force produced by relative movement of the support means and/or the brake.

The light modulation device has a modulator that receives a first electrical signal from a control unit of the elevator installation, wherein the modulator, in order to modulate the first electrical signal, controls a lighting device in the elevator car having two or more light-emitting diodes. The lighting device generates a first light signal to encode the first electrical signal, and the modulator switches the light-emitting diodes on and off synchronously or asynchronously and/or adjusts their brightness.
