Filed:

Jun 23, 2020

Appl. No.:

16/909120

Inventors:

- Farmington CT, US
Sam Thieu Wong - Bridgeport CT, US

International Classification:

B66B 1/46
B66B 1/34
B66B 3/00
B66B 1/24
H04W 4/029

Abstract:

An aspect includes a system with a communication interface configured to receive a mobile device location indicator at a first location and a second location. The system also includes a memory system and a processing system configured to perform operations. The operations include detecting a mobile device at the first location and observing a current state of one or more conditions present during detection of the mobile device. A travel prediction of the mobile device between the first location and the second location is determined based on a travel history of the mobile device and the current state of the one or more conditions. A command is output to a dispatching system based on detection of the mobile device at the first location and the travel prediction of the mobile device to align with a predicted arrival of the mobile device at the second location.

Appl. No.:

16/809643

Inventors:

- Farmington CT, US
Sam T. Wong - Bridgeport CT, US

International Classification:

B66B 1/46
H04W 4/02

Abstract:

Provided are embodiments of a method for operating a receiverless device positioning. The method includes receiving a first request corresponding to a first location, registering data associated with the first request, and receiving a second request at a second location, the first location is different than the second location. The method also includes comparing the first and second location, and time between the first request and the second request, and allowing the second request based at least in part on the comparison. Also provided are embodiments of a system configured to perform receiverless positioning.

International Classification:

B66B 7/12
B66B 5/00

Abstract:

A rope sway detection system of an elevator system includes a magnetic pickup located adjacent to a suspension member of an elevator system. The magnetic pickup is configured to detect a movement of the suspension member via a change in a magnetic field at the magnetic pickup. A signal processing unit is operably connected to the magnetic pickup. The signal processing unit is configured to determine a maximum amplitude of a sway of the suspension member based on the change in the magnetic field, compare the maximum amplitude to a preselected threshold, and signal a change in operation of the elevator system based on an actual or predicted exceedance of the threshold.
