A method can be used to operate an elevator system that comprises multiple elevator shafts, an elevator car, and a shaft changing unit. The elevator car can change from a first elevator shaft into a second elevator shaft by way of the shaft changing unit. To convey a user of the elevator system from a starting position to a destination position, a route is determined from a plurality of route options whereby initial values are taken into account for the determination of the route. In this context, a specification relating to use of the shaft changing unit is taken into account as an initial value from the initial values for the determination of the route.

A first retention device of the mechanism is disposed, at least in part, between the first retainer face and the first lane structure. The first retention device is supported by the elevator car and is constructed and arranged to contact the first retainer face for limiting lateral movement of the elevator car away from the first lane structure and toward the second lane structure.

A linear flux switching permanent magnet (FSPM) motor includes a longitudinal linear stator with stator teeth facing an air gap and a mover including at least one armature including armature teeth, which are spaced apart by slots for receiving an armature winding. At least some, preferably all of the armature teeth embed at least two permanent magnets, respectively, which are positioned successively in longitudinal direction of the tooth, whereby the two permanent magnets have different magnetic properties.

An elevator system may include a ropeless direct drive, a rail system, an elevator car, and a brake. The elevator system may also include a component on which there is arranged a sensor for sensing oscillations. The elevator system further comprises a processing unit for calculating counter-oscillations on the basis of the sensed oscillations. The elevator system also include means for generating the calculated counter-oscillations, which may also be disposed on the component. A corresponding method may involve sensing oscillations outside an elevator car, calculating counter-oscillations based on sensed oscillations, and generating the calculated counter-oscillations outside the elevator car.

Examples of the present disclosure describe systems and methods of determining online identity reputation. In aspects, an online identity of an entity may engage in online interactions. The content provided by the online identity may be accessed and analyzed to determine interaction characteristics and reputation metrics for the online identity. Based on the reputation metrics, the online identity and/or entity (and content therefrom) may be filtered from further online interactions. In some aspects, interaction data may be stored in a data store. An interaction mapping component having access to the data store may analyze the data store data to determine mappings between online identities, entities and interactions. In at least one aspect, an opt-in certificate system may also be provided. The opt-in system may provide an online identity or entity a certificate to securely validate identity.

A guide rail for an elevator system may comprise at least two rail elements that together form a guide rail portion having a functional running track that extends in a travel direction. Each of the rail elements may be connected to a shaft wall of the elevator system. Furthermore, the at least two rail elements may be adjacent and spaced such that the at least two rail elements can thermally expand freely in the travel direction.

An elevator car travels in a lane (113, 115, 117) of an elevator shaft (111). A linear propulsion system imparts force to the car (214). The system includes a first part (116) mounted in the lane of the shaft and a second part (118) mounted to the elevator car configured to co-act with the first part to impart movement to the car. Car state sensors (360a-c) are disposed in the lane and determine a state space vector of the car within the lane. A sensed element (364) on the car is sensed by the plurality of car state sensors when the car is in proximity to the respective car state sensor.
