Disclosed is a mobile device configured to communicate over a network with a controller of an elevator system, wherein the mobile device is configured to: initiate a service request call over the network to the controller; transmit, to the controller during the service request call, a service request for an elevator service at a first level; receive, from the controller, a first data including a reference number that is indicative of an elevator assignment assigned to an elevator car in response to the service request, wherein the elevator assignment instructs the elevator car to travel to the first level; automatically initiate a status update call over the network to the controller when the service request call terminates before receiving the elevator service; and transmit, to the controller during the status update call, a second data including the reference number without transmitting an additional service request for the elevator service.

Method and apparatus for securing elevator service over a telecommunications network

Provided are techniques for performing validation of a passenger boarding, where the embodiments include receiving a call request, and detecting beacon information responsive to the call request. The techniques also include validating a boarding status of a passenger that placed the call request based at least in part on the beacon information, and responsive to the validation, transmitting a notification of the boarding status.

Validation of elevator call passenger boarding

An elevator system is provided. Aspects includes at least one elevator car, a plurality of sensors, a controller coupled to a memory, the controller configured to receive a call request for an elevator car from a user device. An identifier is transmitted to the user device and to the plurality of sensors. A location of the user device is determined based at least in part on at least one sensor in the plurality of sensors detecting the identifier on the user device. And the at least one elevator car is operated based on the location of the user device.

E-call registration for elevator

A method for object detection within an elevator car including: transmitting radar signals at a selected polarization into an elevator car towards an individual; receiving reflected radar signals at a reflected polarization; comparing the reflected polarization to the selected polarization; determining that the individual is in possession of a metal object in response to comparing the reflected polarization to the selected polarization; and activating an alert in response to the determining that the individual is in possession of the metal object.

Method and apparatus for elevators to detect concealed object and inform building management system

An elevator system is provided. Aspects includes an elevator car, a sensor affixed to the elevator car, wherein the sensor is operated by a controller, the controller is configured to receive occupancy data associated with the elevator car. The occupancy data is analyzed to determine an occupancy of the elevator car. A first hall call is received and based at least in part on the occupancy and the first hall call, adjusting operation of the elevator car in the elevator system.

Elevator operation for occupancy

Disclosed is an elevator system in a building, the elevator system including a first elevator car for transporting a passenger between a plurality of building levels, the system including a controller that controls the elevator car, the controller: rendering a first determination that the passenger has requested elevator service from the first lobby, rendering a second determination to assign the elevator car to provide service to the passenger at a first lobby for the first level, effecting a first transmission to the elevator car to effect the second determination, rendering a third determination that the first lobby becomes unoccupied in a time period between effecting the first transmission and the elevator arriving at the first lobby for servicing the first passenger, rendering a fourth determination to release the elevator car from effecting the second determination, and effecting a second transmission to the elevator car to effect the fourth determination.

System for monitoring lobby activity to determine whether to cancel elevator service

Disclosed is an elevator system for a multilevel architectural structure, the system having: a system controller, an elevator and an elevator controller, wherein the system controller and elevator controller communicate over a network, multi-level hoistway in which the elevator travels, the multi-level hoistway including a plurality of egress levels, including a first egress level, the first level being a primary egress level, wherein during an alarm condition the system, when the primary level is inaccessible, performs an emergency assessment of identifying a safe level of the plurality of levels at which to discharge passengers, the assessment comprising obtaining a smoke density profile for the egress levels, the profile illustrating a distribution of smoke within the multilevel structure, analyzing the smoke density profile, identifying a safe level having a smoke density that is safe, and instructing the elevator to discharge passengers on the safe level.

Elevator control to avoid hazardous conditions

An elevator system is provided. Aspects includes an elevator car, a sensor, and a projector affixed to the elevator car, wherein the projector is operated by a controller and the controller is configured to receive an indication of a presence of a passenger in the elevator car. A car operating panel is projected, by a projector, in the elevator car, wherein the car operating panel comprises a virtual element. An activation of the virtual element from the passenger is sensed by a sensor and an action is initiated based at least in part on sensing the activation of the virtual element.
