An elevator system includes an elevator car, an elongate tension member operably connected to the elevator car and configured to move the elevator car, and an elevator car position measurement system. The elevator car position measurement system includes a pulse generator configured to transmit a pulse along the elongate tension member; and a detector unit configured to receive the pulse from the pulse generator after the pulse has been transmitted along a length of the elongate tension member and to record a time at which the pulse is received. One of the pulse generator and the detector unit is arranged to move within the hoistway dependent on a position of the elevator car within the hoistway, such that a length of the elongate tension member along which the pulse is transmitted changes dependent on a position of the elevator car within the hoistway.

Various embodiments are directed to determining an elevator car position within an elevator shaft using radar-based distance measurements and a plurality of radar reflectors positioned along the elevator shaft. In one aspect, an example method is provided. The method includes associating a height segment of the elevator shaft with each of the plurality of radar reflectors. The method further includes selecting a target reflector from the plurality of radar reflectors based at least in part on an initial height of the elevator car being within a height segment associated with the target reflector. The method further includes determining an inferred position of the elevator car within the elevator shaft based at least in part on determining a radar-based distance measurement to the target reflector. The radar reflectors may be positioned such that at least one radar reflector is optimally detectable by a dynamically-positioned radar transceiver of the elevator car.

A landing door of an elevator system has a door leaf equipped with an integrated floor display that indicates to a person the floor at which an elevator car approaching the floor of departure is currently located. The door leaf of the landing door has a wall element made of sheet metal, the floor display having at least one controllable light source arranged behind the wall element, and a cover layer. The wall element has a display segment with a plurality of light passage openings, the light passage openings forming a perforated screen structure. The cover layer functions such that after the light source is activated to display the desired floor information, light from the light source penetrates through the light passage openings and the cover layer to the outside and when the light source is deactivated, the cover layer does not let light through to the outside.

Acquisition of position information of an elevator car. The system for acquiring the position information of an elevator car of the invention comprises: a first Bluetooth module travelling in an up-down direction of an elevator hoistway following the elevator car, and a second Bluetooth module disposed in the elevator hoistway; wherein the second Bluetooth module broadcasts a Bluetooth signal containing an identifier of the second Bluetooth module to the elevator hoistway, and the first Bluetooth module senses signal strength information of the Bluetooth signal it receives and determines the identifier corresponding to the second Bluetooth module broadcasting the received Bluetooth signal; the system is configured to determine the position information of the elevator car according to received signal strength information of the Bluetooth signal and a corresponding identifier.

An elevator system in which an elevator car can be moved between floors in a manner controlled by an elevator controller is described. A car call device is communicatively connected to the elevator controller for inputting a destination floor is arranged in the elevator car. Elevator operation devices are communicatively connected to the elevator controller are arranged on the floors for the input of calls. An elevator operation device has a touch-sensitive screen system equipped with a substantially smooth touch surface and which responds with haptically perceptible feedback to a touch of the touch surface by a passenger.

A stabilizing system may be utilized to reduce or eliminate sway of magnetic tape that is suspended in an elevator hoistway and provides a positional reference to an elevator cab. The stabilizing system may include a stabilizing mechanism fixed within a hoistway and a roller cam disposed on the elevator cab. The stabilizing system may include a telescoping member attached to a guide having opposing flanges that restrict movement of the tape. The telescoping member and the guide may be biased in an extended position, where the guide partially surrounds the tape. In a retracted position, the guide is horizontally spaced apart from the tape. When the elevator cab passes the stabilizing mechanism, the roller cam may force the guide and the telescoping member into the retracted position to prevent any contact between the stabilizing mechanism and components disposed on the elevator cab.

A passenger tracking system includes a multiple of sensors for capturing depth map data of objects. A processing module in communication with the multiple of sensors to receive the depth map data, the processing module uses the depth map data to track an object and calculate passenger data associated with the tracked object to generate a passenger tracking list that tracks each individual passenger in the passenger data from an origin lobby to a destination lobby and through an in-car track between the origin lobby and the destination lobby.
