Elevator safety and control systems including an elevator car moveable within an elevator shaft, at least one operational state element associated with movement of the elevator car within the elevator shaft, a passenger sensor positioned within the elevator car and configured to monitor an occupancy area of interest inside the elevator car and to observe at least one passenger located in the occupancy area of interest, and an elevator control module in communication with the passenger sensor and the at least one operational state element. The elevator control module is configured to determine an emergency state of operation of the elevator car, determine a presence of at least one passenger within elevator car, and perform emergency response action.

A method for controlling an elevator includes controlling the speed of a vertically moving elevator car during its run from a starting landing to a destination landing according to speed settings, the speed settings defining a constant target speed for the elevator car. The method includes obtaining measurement data of the ongoing run, which measurement data describes vertical speed and/or vertical acceleration of the vertically moving elevator car, determining whether the measurement data meets one or more predetermined criteria indicating unintended vertical speed and/or unintended vertical acceleration, and changing the speed settings of the current run by lowering the constant target speed from a first constant target speed to a second constant target speed if the measurement data meets said one or more predetermined criteria, continuing the run without intermediate stops to said destination landing. An elevator is provided to implement the method.

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 method of controlling building systems is provided. The method comprising: detecting a status parameter of an elevator door; and displaying the status parameter of the elevator door on a device.

Embodiments of the invention are directed to computer-implemented methods, computer systems, and computer program products for operating an elevator car. The method includes receiving first inputs from one or more sensors. The method further includes receiving second inputs from one or more cameras. The method further includes determining the presence of a passenger on the elevator using the first inputs and the second inputs. The method further includes determining a set of characteristics related to the passenger using the first inputs and the second inputs. The method further includes predicting a set of predicted actions of the passenger, using machine-learning techniques. The method further includes determining an action to perform based on the set of predicted actions.

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.

An elevator system includes at least one elevator car movable between a plurality of landings. The elevator system is operable in an occupant evacuation operation mode. In the occupant evacuation operation mode, at least one safe room is associated with at least one of the plurality of landings.

Disclosed is an elevator system having: a holding relay configured to energize and deenergize a circuit, the holding relay configured to communicate over a wireless network with a mobile device, wherein the holding relay is configured to: deenergize the circuit responsive to receiving a first signal via the wireless network from the mobile device, indicative of the mobile device being in or near a first architectural location.

An elevator system, having: a car that operates normal and inspection modes; a sensor assembly; a safety chain; wherein while in the normal mode, the sensor assembly: monitors in a first sensing mode to detect whether an object is within a first area, and then monitors in a second sensing mode that is more sensitive than the first sensing mode to again detect the object; and upon determining that the object is potentially human, the safety chain is opened; and while in the inspection mode, the sensor assembly: bypasses the first sensing mode and monitors in the second sensing mode to detect whether the object is located in the first area; and upon detecting that the object is located in the first area, the safety chain is opened.

An elevator system, having: a hoistway, a pit and an elevator car; a sensor assembly, wherein the sensors are distributed about the elevator car and configured to form a virtual safety net (VSN) around at least a portion of a first area that is exterior to the elevator car; and an elevator safety, wherein the sensor assembly is configured to: monitor for a breach of the VSN by an object that is potentially human; and upon detecting the breach of the VSN by the object, opening the elevator safety chain and stoping the elevator car.
