  • Patent number: 11577931
    Abstract: An elevator system having a controller configured for: receiving a communication from the mobile device for a passenger, the communication including first data, wherein the first data is position data obtained by the mobile device executing a multilateration (MLAT) process with one or more proximately located telecommunication devices, rendering a first determination, from the first data, that the mobile device is proximate a first distance from the lobby, rendering a second determination, from the first determination, arrive at the lobby proximate a first time, and transmitting a communication to an elevator instructing the elevator to arrive at the lobby proximate the first time to provide elevator service.
    Type: Grant

  • Patent number: 11535489
    Abstract: A method of health profile based elevator calls is provided. The method is implemented by a system comprising an elevator. The system is in communication with a mobile device of a user. The system determines a distance between a lobby respective to the at least one elevator and the mobile device and acquires a health profile of the user from the mobile device. The system, then, determines a travel time based on the distance and the health profile. Next, the system executes an elevator call for the elevator with respect to the travel time.

  • Patent number: 10850948
    Abstract: An escalator system wherein when a handrail belt is moving from rotation of a plurality of elevator sheaves: a controller receives data from a plurality of sensors, identifies from the data a first sheave of the plurality of sheaves as comprising reference alignment value for the system, determines for the plurality of sheaves a respective plurality of alignment values, compares the plurality of alignment values with the reference alignment value, and provides a predetermined response when any of the plurality of alignment values diverges from the reference alignment value by more than a predetermined amount.
