Abstract: An elevator system may include an elevator car that is configured to transport a passenger between floors of a building as well as a sensor system in the elevator car that is configured to detect a passenger's location, orientation, and/or height. The elevator system may further include a touchscreen that can display a virtual car operating panel at a location on the touchscreen that is based on the location, orientation, and/or height of the passenger. The virtual car operating panel may be configured to receive input from the passenger regarding a destination floor. The touchscreen may be configured to display a virtual car operating panel for each passenger based on each passenger's location, orientation, and/or height on the elevator car.

Abstract: A method of operating an emergency power supply for an elevator cabin includes determining a remaining power supply capacity of an energy storage device of the emergency power supply, determining a power demand of an electrical consumer, and predicting how long the energy storage device is capable of providing the electrical consumer with power, based on the determined remaining power supply capacity and the determined power demand. An emergency power supply for an elevator cabin includes an energy storage device configured to provide emergency power to an electrical consumer in the elevator cabin, and a control unit. The control unit is configured to control operation of the energy storage device, determine a remaining power supply capacity of the energy storage device, determine a power demand of the electrical consumer, and predict an amount of time for which the energy storage device is able to power the electrical consumer.
