Assignee:

Otis Elevator Company - Farmington CT

International Classification:

H04L 2300

US Classification:

375377

Abstract:

A binary data communication system includes a transmitter unit coupled to a receiver unit via a communications link. The transmitter sends a message signal packet to the receiver. The packet includes data arranged according to mixed protocols. The receiver unit includes a program for detecting both protocols, and for converting data from one protocol (or format) into the other format.

International Classification:

B66B 5/00
B66B 1/34
G06F 17/30

Abstract:

A service tool for interfacing with an equipment system includes a processing system, a display, and a memory system having a plurality of instructions stored thereon that, when executed by the processing system, cause the service tool to establish communication with an equipment controller of the equipment system and capture a plurality of state samples of one or more equipment system parameters distributed over multiple sampling times as a plurality of captured data in a trace buffer of the service tool. The instructions when executed by the processing system cause the service tool to store the captured data from the trace buffer to one or more files in the memory system of the service tool and replay the captured data from the one or more files on the display of the service tool responsive to a replay request.

International Classification:

G06F 21/31
H04L 29/06

Abstract:

A service tool credential management system includes a storage medium operable to store a plurality of instructions and at least one processor configured to execute the instructions to send a credential request to a networked server to access an equipment controller with a service tool. The at least one processor is further configured to execute the instructions to receive an access credential responsive to the credential request and utilizing one or more fields of the access credential during interactions with the equipment controller to enable a level of access for the service tool to the equipment controller corresponding to the access credential.

International Classification:

B66B 5/00
B66B 1/28

Abstract:

A service tool function availability adjustment system includes a storage medium operable to store a location-based function availability map and at least one processor configured to determine a location of a service tool in relation to one or more equipment components of an equipment service system. The at least one processor configures an availability of one or more functions of the service tool to interact with the one or more equipment components of the equipment service system based on the location-based function availability map and the location of the service tool.

H04W 12/06
B66B 1/34

Abstract:

A service tool proximity detection system includes a service tool and an equipment controller. The service tool is operable to establish communication with the equipment controller of an equipment service system. At least one processor of the service tool proximity detection system is configured to generate a location proximity indicator to verify proximity of the service tool to a predetermined service location of the equipment service system, determine that the service tool is located local to the predetermined service location based on verifying that a response to the location proximity indicator matches an expected response, determine that the service tool is located remote from the predetermined service location based on verifying that the response to the location proximity indicator fails to match the expected response, and configure one or more functions of the service tool based on the location of the service tool relative to the predetermined service location.
