A service alarm device for use in an elevator system, the service alarm device including a control board configured to receive at least one safety signal, and an alarming device in communication with the control board, wherein the control board is configured to activate the alarming device based on the at least one safety signal.

A safety device includes an external device for the use of inspection within an elevator hoistway, and a human detection sensor in electrical communication with the external device and an elevator controller. The human detection sensor is configured to detect presence of a person within the hoistway in response to the ON operation of the external device to prevent movement of the elevator car.

Safety systems and methods for elevator systems include an elevator car configured to travel along an elevator shaft, a pit at a bottom of the elevator shaft, and a governor having an energizable actuator configured to be continuously energized from a time of activation to a time of reset, the governor configured to stop downward movement of the elevator car along the elevator shaft after the time of activation until the time of reset, with energizing of the energizable actuator being initiated from an electrical trigger mechanism proximate the pit of the elevator shaft.

An illustrative example elevator system includes an elevator car, a machine that selectively causes movement of the elevator car, and a drive that controls the machine to control movement of the elevator car at an intended elevator car speed. The drive is configured to use information regarding operation of the machine to determine whether an abnormal passenger behavior (APB) condition exists that affects movement of the elevator car. The drive is configured to alter the elevator car speed when the APB condition exists.

An electrical or electromechanical installation includes a central processor for controlling operation of the electrical or electromechanical installation, a computer communicatively coupled to the central processor to output a control signal to the central processor, and a first video camera communicatively coupled to the computer to output an image signal to the computer. The computer has a memory storing computer instructions to determine facial characteristics from a person's face data comprised in the image signal, to categorizing the facial characteristics into at least one of predefined emotion categories, and to generate a control signal corresponding to the at least one of predefined emotion categories. The central controller operates the electrical or electromechanical installation in accordance with one of several operational modes, wherein the one of several operational modes is selected as a function of the control signal.

A device for generating information representing a condition of an automatic door includes an accelerometer including at least one internal buffer and a control unit including at least one processor and at least one memory. The accelerometer is configured to obtain and buffer at least one acceleration value representing acceleration of the automatic door. The at least one processor is configured to cause the control unit at least to read and store the obtained at least one acceleration value from the internal buffer of the accelerometer, and generate at least one piece of information representing the condition of the automatic door for communicating the generated at least one piece of information to an external server. A system and a method for generating information representing a condition of an automatic door are also disclosed.

During an evacuation situation in a building that is equipped with an elevator system and in which a plurality of fixed point markers are arranged at defined sites, an escape route is transmitted to a person by means of a mobile device. The fixed point markers store data that can be received by the mobile device. An instantaneous position of the mobile device can be determined when the mobile device uses data received from a fixed point marker to access a database in which the data is linked to a site of the fixed point marker. The ascertainment of the escape route to a destination is based on the instantaneous position of the mobile device. The person is registered on reaching the destination when the mobile device is detected at the destination.

A detection system is provided. The detection system includes a sensing device and a controller. The sensing device is within an elevator and in communication with the controller. The sensing device continuously monitors sound waves within the elevator and communicates the sound waves as electrical signals to the controller. The controller operates the elevator and analyses the sound waves received as the electrical signals from the sensing device to detect an emergency condition within the elevator.

An exemplary building sway operation system (10) for an elevator includes an acceleration sensor (11), and a data receiving unit (12) for receiving a sensor output from the acceleration sensor (11). The acceleration sensor (11) is designed to be mounted on a movable mass (6) of an active vibration control device (5) for a building, in order to detect the reciprocating motion of the movable mass (6) of the active vibration control device (5) responsive to the occurrence of earthquakes or strong winds.
