A drive signal for driving the electromagnet is generated based on the braking torque and is supplied to the electromagnet, wherein, when the car is braked, an actual car deceleration is ascertained and calibration is performed based on the ascertained actual car deceleration, specifically calibration of the ascertained required braking torque or calibration of the drive signal that is generated based on the ascertained required braking torque.

Abstract: In an approach for determining an optimal path for an elevator, a processor receives information, wherein the information includes social media data associated with a user and calendar entries associated with the user, indicating one or more locations within a building. A processor analyzes the received information. A processor determines a location to send an elevator within the building to minimize movement of the elevator, based on the analyzed information. A processor causes the elevator to move to the location.

Abstract: An operating panel for an elevator includes a panel plate having an opening, a key switch arrangement and, optionally, a human machine interface attached to the panel plate. The switch arrangement includes a cover arrangement, a hinge and a key switch. The key switch is attached to the cover arrangement and is activated or deactivated by a key for transmitting activation signals to the elevator control upon activation.

Thus, the key switch is protectively stored in the first configuration, providing splash water protection and an attractive visual appearance, and is pivoted to the second configuration when needed.

Abstract: An elevator system (100) includes an elevator car (102) that is configured to travel along a guide rail (104), and a braking assembly (116) coupled to the elevator car (102). The braking assembly (116) is configured to selectively operate in a disengagement mode that allows the elevator car (102) to travel along the guide rail (104), and an engagement mode that inhibits the elevator car (102) from traveling along the guide rail (104). The electronic braking assembly controller (128) is in signal communication with the braking assembly (116) and is configured to generate an electronic braking signal that activates the engagement mode of the braking assembly (116). When the engagement mode is activated, the elevator car (102) decelerates without exceeding a predetermined g-force (g) threshold regardless as to whether a load applied to the elevator car (102) changes such that the elevator car (102) is stopped at a floor landing (106).

Abstract: A safety device of a lift system may include a car, an evaluation device, and a measuring device. Conditions where departure from a door zone with an open car door or where impermissible accelerations/speeds are reached within the door zone are identifiable by way of the evaluation device and output signals from the measuring device. In such conditions, a control signal may be generated for braking the car. A safety circuit may be connected to the evaluation device and ensure a first safe zone in a shaft head of a lift shaft during an inspection run. The safety circuit may have a safety switch, and the car may include a tripping means for tripping the safety switch. The safety switch and the tripping means have a first relative position upon which the first safe zone is based, and entry of the car into the first safe zone during the inspection run is preventable by tripping the safety switch, which leads to generation of the control signal and braking of the car.
