A smartwatch includes a destination handling unit configured to issue a destination call in an elevator system of an environment. The smartwatch has an input for entering destination data as well as an output for indicating an allocated elevator of the elevator system. The smartwatch includes a navigation system including a memory with map data of the environment. The navigation system includes a position detector for detecting the location of the smartwatch within the environment, and a navigation output connected with the output. The navigation system is coupled with the destination handling unit to issue a destination call based on data of the position detector and/or for providing navigation guide data based on an issued destination call.

An elevator safety system includes: at least two sensors, each of the sensors being configured for monitoring at least a portion of a hoistway of an elevator system and providing monitoring signals; a transformation unit which is configured for transforming the monitoring signals provided by at least one of the sensors and producing transformed signals corresponding to a common direction of vision; a comparison unit which is configured for comparing the at least two transformed signals and for generating a failure signal if a difference between the at least two transformed signals exceeds a predetermined threshold; and a detection unit, which is configured for detecting a person or undesired item in at least one of the two transformed signals and for generating an alarm signal if a person or undesired item is detected.

A method for controlling a passenger flow in a building includes: dividing a group of elevators to sub-groups; receiving a service call; selecting a sub-group to provide a service and generating an indication for indicating the selected sub-group; selecting a first candidate elevator; evaluating a second candidate elevator by comparing the second forecast time to the first forecast time; selecting the second candidate elevator to provide the service if the second forecast time is less than the first forecast time. The evaluation is continued until a selection is locked for the service call due to at least one characteristic relating to the elevator system. The invention also relates to a group controller, a computer program product, and an elevator system.

Methods and systems for controlling elevator systems are provided. The methods include receiving inputs from at least one interactive input device, wherein the inputs include elevator call requests, tracking one or more people located within a monitored area using at least one sensor, assigning elevator assignments to the one or more people based on at least one of the inputs from the at least one interactive input device and a grouping algorithm based on the tracking of the one or more people, and scheduling operation of at least one elevator car based on the elevator assignments.

An aspect includes capturing crowd data associated with a lobby area of an elevator system. A dispatching schedule of one or more elevator cars of the elevator system is adjusted based on the crowd data. A notification of the adjustment to the dispatching schedule is output.

The invention refers to an elevator system having a plurality of elevator cars, which elevator cars comprise several first cars and at least one second car, which second car differs from the first cars in its size and/or technical configuration, whereby the first cars and the second car run together within one and the same elevator shaft, which elevator system comprises an elevator control comprising a call allocation control having a first part connected to at least one call input device for allocating the first elevator cars and a second part connected to at least one call issuing means for the call allocation of the second car, whereby the first and second part of the call allocation control are configured to work independently of each other.

Disclosed is an elevator system having: a controller; an elevator car operationally connected to the controller; a first sensor configured to provide first sensor data to the controller, wherein the controller is configured to identify a capacity parameter of the elevator car, wherein the capacity parameter includes one or more of: loaded weight; volume of available space; or volume of occupied space; a second sensor configured to provide second sensor data to the controller, wherein the controller is configured to determine that passengers remain outside the elevator car when the elevator car is stopped at a landing and its elevator doors are open; and wherein from the first sensor data and the second sensor data, the controller is configured to determine a reduced capacity limit for the elevator car as a function of the capacity parameter.

Provided is a communication system and a communication method for use in an elevator system, which belong to the field of elevator intelligent control technologies. The communication system of the present invention comprises: a first bluetooth module mounted in an elevator landing area of the elevator system and a second bluetooth module mounted in an elevator car of the elevator system. The communication system and the communication method of the present invention can realize that a passenger completes an elevator calling operation in a completely hand-free mode, which is easy to realize and is low in cost.

A load-bearing apparatus (100) comprises a winch apparatus (110), and a load-bearing spoolable medium (120) for connecting to a load, the load-bearing spoolable medium comprising a plurality of load-bearing elements (121-123); wherein at least a portion of the load-bearing spoolable medium is spooled about the winch apparatus. The provision of multiple load-bearing elements may help reduce the diameter appropriate for the winch apparatus, while maintaining the necessary load bearing capacity for supporting, paying in and/or paying out the load. The load-bearing apparatus may comprise a tension control apparatus (151-153) for controlling, applying and/or adjusting the tension of the load-bearing spoolable medium.

A method of operating a building elevator system having a plurality of elevator systems organized into an elevator group including: detecting crowd data within an elevator lobby proximate the elevator group on a landing; determining a level of crowdedness in response to the crowd data; determining at least two elevator cars of the plurality of elevator systems are required in response to the level of crowdedness; dispatching an elevator car of a first elevator system of the plurality of elevator systems to the landing; dispatching an elevator car of a second elevator system of the plurality of elevator systems to the landing; and coordinating an arrival time of the elevator car of the first elevator system at the landing and an arrival time of the elevator car of the second elevator system at the landing.
