Abstract: A method of avoiding unnecessary safety brake actuation in an elevator system. The method includes determining whether a true overspeed or overacceleration condition of an elevator car is present. The method also includes activating the electronic safety actuator if a true overspeed or overacceleration condition of the elevator car.

Abstract: An electronic speed detection system is provided. The electronic speed detection system includes an accelerometer coupled to a moving object and a hybrid altimeter, which includes a first pressure sensor coupled to the moving object and a second pressure sensor. The electronic speed detection system also includes a controller comprising a memory and a processor. The memory storing computer program instructions executable by the processor to cause the electronic speed detection system to determine a normalized position based on first inputs received from the hybrid altimeter, or determine a corrected velocity position based on a second input received from the accelerometer and the normalized position.

Abstract: A processor-implemented method for pushing a revision to an automated passenger conveying subsystem is provided. The processor-implemented method receives the revision over a network to make the revision available to one or more subsystems. An application executed on a processor of the network, then, receives a selection input identifying the automated passenger conveying subsystem of the one or more subsystems. In turn, the application sends a message to the automated passenger conveying subsystem based on the selection input. The message identifies that the revision is available for downloading and deployment. An exchange operation is executed to push the revision to the automated passenger conveying subsystem.

Abstract: A mobile-based equipment service system includes a remote server, a mobile device, and at least one equipment controller. The mobile device includes a user interface, and is configured to send a user authentication message, initiated by a user via the user interface, to the remote server. The remote server is configured to verify the user via the user authentication message and once verified, send an encrypted blob to the mobile device in response to the user authentication message. At least one equipment controller is configured to receive and decrypt the encrypted blob from the mobile device.

Abstract: A brake assembly for an elevator system is provided and includes a guide rail configured to guide movement of an elevator car. Also included is a safety brake operatively coupled to the elevator car and having a brake surface configured to frictionally engage the guide rail. Further included is a safety brake actuation mechanism operatively coupled to the safety brake and configured to actuate the safety brake to a braking position. The mechanism includes a first sensing device disposed on a first side of the guide rail to detect a first condition reading of the elevator car relative to the guide rail. The mechanism also includes a second sensing device disposed on a second, opposite side of the guide rail to detect a second condition reading of the elevator car relative to the guide rail, the first and second condition readings collectively analyzed to determine an overall condition reading.
