Abstract: The present invention discloses a method and an elevator system, in which a passenger gives elevator calls with a personal terminal device. An elevator car is allocated to the passenger on the basis of an elevator call, the maximum time from the moment of giving the call to the moment the doors of the allocated elevator car will close on the call-giving floor is calculated. The aforementioned maximum time is sent to the terminal device of the passenger for being presented to the passenger on the terminal device.

Abstract: An elevator system is provided and includes a sensor assembly and a controller. The sensor assembly is disposable in or proximate to an elevator lobby and is configured to deduce an intent of an individual in the elevator lobby to board one of one or more elevators and to issue a call signal in response to deducing the intent of the individual to board the one of the elevators. The controller is configured to receive the call signal issued by the sensor assembly and to assign one or more of the elevators to serve the call signal at the elevator lobby.

Abstract: An elevator automatic rescue and energy-saving control method, the method comprising: when the power grid supplies power normally, selecting a single current in a three-phase power grid (9) as an AC power supply for an elevator control system (10); controlling a DC-DC converter (2) to charge the super capacitor module (1) connected to the DC-DC converter to a specified standby electric energy level; and when the power grid is suddenly interrupted, selecting to use the electric energy stored in the super capacitor module (1) as a rescue electric energy for a traction motor (7) and the elevator control system (10). The described method uses a super capacitor module, so that a stable and reliable elevator rescue power supply is provided when the power grid is suddenly interrupted, and the regenerative electric energy dissipated during elevator braking operation is stored and utilized during elevator operation, thereby conserving energy.

Abstract: A method of operating an elevator system (10) includes identifying one or more components (46, 48, 50, 52) in an elevator hoistway (14) requiring periodic maintenance and/or inspection and programming hoistway component locations of the one or more components into an elevator car control system. The elevator car (12) is driven to a programmed hoistway component location of a selected component of the one or more components utilizing the hoistway component location programmed into the elevator car control system. The selected component is accessed from inside the elevator car (12) to perform maintenance and/or inspection of the selected component.

Abstract: An elevator system (100) includes an elevator car (102) that is configured to travel along a guide rail (104), and a braking assembly (116) coupled to the elevator car (102). The braking assembly (116) is configured to selectively operate in a disengagement mode that allows the elevator car (102) to travel along the guide rail (104), and an engagement mode that inhibits the elevator car (102) from traveling along the guide rail (104). The electronic braking assembly controller (128) is in signal communication with the braking assembly (116) and is configured to generate an electronic braking signal that activates the engagement mode of the braking assembly (116). When the engagement mode is activated, the elevator car (102) decelerates without exceeding a predetermined g-force (g) threshold regardless as to whether a load applied to the elevator car (102) changes such that the elevator car (102) is stopped at a floor landing (106).
