An elevator safety system (20) for an elevator system (2) with a self-diagnostic functionality includes at least two safety channels (22a, 22b), wherein each safety channel (22a, 22b) is configured for supplying a safety signal (23a, 23b) in case a safety issue has been detected. The elevator safety system (20) comprises a self-diagnostic evaluator (24), which is configured for receiving any safety signals (23a, 23b) supplied via the safety channels (22a, 22b); starting a timer (25) for measuring a predetermined period of time in case a safety signal (23a, 23b) is supplied on one of the safety channels (22a, 22b); and stopping any further operation of the elevator system (2) in case the received signal (23a, 23b) is still supplied after the predetermined period of time has expired.

A mobile terminal of the present invention is configured to test a wireless beacon that is mounted in an elevator system and used for establishing a wireless connection with the mobile terminal and receiving service request commands. The wireless beacon is at least coupled to an elevator controller of the elevator system. The mobile terminal is configured to include: a connection testing module configured to test whether the wireless beacon can successfully establish the wireless connection with the mobile terminal and/or configured to test whether the wireless beacon can successfully establish a communication connection with the elevator controller; and a service request testing module configured to send a service request test command to the wireless beacon to enable the wireless beacon to automatically complete a service request test on the wireless beacon.

A method for monitoring thresholds for performance attributes in an elevator system is provided. Aspects includes collecting, by a sensor affixed to an elevator car, sensor data associated with the elevator system wherein the sensor data comprises one or more performance attribute values for a set of performance attributes of the elevator system. Obtaining a threshold profile associated with the elevator system, wherein the threshold profile comprises thresholds for each performance attribute in the set of performance attributes of the elevator system. Comparing the one or more performance attribute values to corresponding thresholds for the set of performance attributes and transmitting an alert for any of the one or more performance attribute values exceeding the corresponding thresholds for the set of performance attributes.

A control unit, an elevator-monitoring apparatus and a method are used to monitor a maintenance mode of an elevator installation. The control unit has a controller and a memory device, wherein the controller receives a first signal when a locking device of shaft door is locked and receives a second signal when the locking device is unlocked. The controller compares a chronological signal sequence of first signals and second signals with a reference sequence stored in the memory device for actuation of the locking device and, if the signal sequence of the first signals and second signals matches the reference sequence, ends the maintenance mode and releases a car of the elevator installation for a traveling operation.

The invention relates to methods and arrangements for creating a safe working space in the upper part of an elevator shaft. A position of an elevator car in the elevator shaft in relation to a plurality of safety levels in the elevator shaft may be monitored, where each safety level is associated with a separate clearance of the elevator car from a ceiling of the elevator shaft. The elevator may be controlled to create a safety space zone at the upper part of the elevator shaft. The controlling may include progressively activating separate braking systems in response to the elevator car progressively moving upwards through separate triggering limits of separate clearances, to progressively strengthen an arresting of upwards movement of the elevator car through the elevator shaft.

The present invention is a device for moving people or items on the Jewish Sabbath and certain Jewish holidays in a manner that is widely acceptable within Jewish Law through powering and controlling this invention with municipal water. The invention includes applying this technology to elevators, escalators, dumbwaiters, conveyors, stair lifts, porch lifts, and more. Within the invention are certain components and groups of components that are unique in their arrangement and purpose.

The present invention relates to determining the movement of a passenger relative to an elevator landing area, which belongs to the field of elevator intelligent control technologies. An automatic elevator calling system of the present invention comprises: a first wireless signal module installed in an elevator car, which is used for broadcasting a first wireless signal; wherein the first wireless signal module is further used for receiving information regarding the movement of a passenger relative to the elevator car, and the information regarding the movement is determined based on the change in a signal strength of the first wireless signal received by a personal mobile terminal carried by the passenger.

Elevator systems and methods of use including an elevator car located within an elevator shaft, at least one sensing device arranged within the elevator car, an elevator controller arranged to control at least one of an operating condition and at least one feature within the elevator car, and a computing system in communication with the at least one sensing device and the elevator controller, wherein the computing system is arranged to detect a passenger state of a passenger within the elevator car and configured to control the operating conditions and features within the elevator car based on the detected passenger state.

A station device in a biometric pre-identification system uses identity to perform one or more actions. Identities are determined (such as via a backend) using biometric information. A biometric pre-identification device obtains biometric information and/or a digital representation thereof from a person approaching the station device. The biometric pre-identification device transmits such to the station device, facilitating the station to begin and/or perform various actions. The station device begins or performs the actions using the identity determined based on the biometric information before the person arrives at the station device.

A system for elevator door sensor fusion, fault detection, and service notification is provided. The system includes a processor and a memory including computer-executable instructions that, when executed by the processor, cause the processor to perform operations. The operations include monitoring outputs of a plurality of sensors. It is determined whether the outputs of the plurality of sensors follow an expected pattern. Based at least in part on determining that the outputs of the plurality of sensors do not follow the expected pattern: identifying a sensor in the plurality of sensors that is not following the expected pattern, and transmitting a notification indicating that the sensor is exhibiting unexpected behaviour.
