A human-machine-interface formed as a landing operation panel or a landing information panel for an elevator installation has: an interaction unit (3) that responds to actuation by a passenger to generate input signals and/or to output output signals to be perceived by the passenger; a communication unit that transmits the input signals to an elevator and/or receives the output signals from the elevator controller; and a supply unit that supplies electrical energy to the interaction unit and the communication unit, the supply unit having an energy conversion unit and an electricity storage unit, wherein the energy conversion unit converts kinetic energy available in the immediate surroundings of the human-machine-interface into electrical energy, and wherein the electricity storage unit stores the converted electrical energy. The human-machine-interface operates with energy autonomy, i.e. without a supply cable to a central power supply.

A system is provided for damping vertical oscillations of an elevator car stopped at an elevator landing. The system includes an elevator traction sheave that receives a torque, a sensor that provides a sensor signal indicative of the torque, a controller that provides a control signal based on the sensor signal, and a motor that applies the torque to the sheave. Oscillations in the torque correspond to the vertical oscillations of the car stopped at the landing during a first (e.g., position control) mode of operation. The motor drives the sensor signal towards a baseline value in response to receiving the control signal during a second (e.g., constant torque control) mode of operation in order to reduce the vertical oscillations of the car.

A non-contact elevator control system having a control panel with multiple buttons, an image processor, a first and a second camera module, wherein the first and second camera modules are arranged at two adjacent corners of the control panel, is disclosed. When an object enters a detection range, the image processor obtains a first imaging position of the object based on a first image taken by the first camera module and a second imaging position of the object based on a second image taken by the second camera module. The image processor calculates the corresponding position of the object in the control panel according to the first and the second imaging positions, and the relative position information of the first and second imaging positions with respect to the first and second camera modules. The image processor triggers a corresponding button in the control panel based on the position.

A method for operating an elevator control system for controlling and monitoring the movements of at least one elevator car when the elevator car approaches individual floors in a building, and in the process stops at a respective floor in a prescribed stopping position, the method including, in conjunction with a floor stop, determining an overall error in the form of a deviation between an actual position of the elevator car and a position of the elevator car assumed as the current position. The elevator control system generates service signals based on a statistical acquisition of several values for the overall error, and/or wherein the overall error is used to ascertain a derivative value, which is taken into account along with the current or stopping position during a comparison between the current position and stopping position performed by the elevator control system for approaching the respective stopping position.
