Abstract:
A method of controlling access to an area accessible by persons, particularly to a space closed by a door, utilizes at least two communications units for transmitting and receiving an identification code and an access code. The identification code is transmitted at a predetermined first transmission power from a first communications unit to at least one second communications unit. The second communications unit checks the identification code and transmits an acknowledgement code at a second transmission power, which is lower than the first transmission power, from the second communications unit to the first communications unit if the check of the identification code was successful. The first communications unit transmits an access code to the second communications unit. After a successful check of the access code by the second communications unit the access is freed.

Abstract:
A method and a system are provided for switching at least one electrical consumer in a building comprising an elevator system. The switched electrical consumer is, for example, a camera. The camera is activated if when using the elevator system the user does not actuate a building door within an ascertained route time, i.e. the user does not arrive at his/her destination. It is possible using an image recorded by the camera to establish whether the user is possibly in a dangerous situation.
Abstract:
A method including: detecting movement of a building door on a floor of a building; based on the detected movement of the building door, defining the floor of the building as a start floor for an elevator trip with an elevator system in the building; and based on the detected movement of the building door, placing a predefined destination call for the elevator trip. The detecting can include determining that a passenger is passing through the building door. A system for performing the method includes: a sensor; an elevator installation in the building; and a control unit coupled to the sensor and to the elevator installation, and configured to detect the door movement using the sensor, define the floor of the building as the start floor, and place a predefined destination call for the elevator trip.
Abstract:
A method for determining a destination call for use by an elevator installation with a control unit and at least one destination call device includes ascertaining several destination calls and making them known to the user by the destination call device. A destination call is selected by a change in position of the user and/or a data communication is activated between the destination call device and a communications unit, which is carried by the user, within a defined range of a radio link section of the destination call device and thereupon a destination call is selected by a change in position of the communications unit inside or outside the radio link section. The selected destination call is communicated to the control unit for serving the destination call.

Abstract:
A method of operating an elevator system in a building with at least one building door includes through opening and/or closing the building door the floor of the opened and/or closed building door is defined as the start floor and a destination call for an elevator car to the start floor is actuated. As soon as the elevator car has reached the start floor, an elevator door of the start floor is opened. As soon as at least one user has entered the elevator car, the opened elevator door is closed and the user is conveyed by the elevator car to a destination floor, wherein the destination floor is defined by a destination call stored for a start floor.
