Abstract: A method for driving an elevator car brake device, an elevator system for executing the method, and a computer program implementing the method involve the brake device including at least one automatically releasable pressure element effecting a braking action and an electromagnet automatically releasing the pressure element, wherein a respectively required braking torque of the car is ascertained using a model of the elevator system, a direction of car travel, a state of load of the car and a desired car deceleration. A drive signal for driving the electromagnet is generated based on the braking torque and is supplied to the electromagnet, wherein, when the car is braked, an actual car deceleration is ascertained and calibration is performed based on the ascertained actual car deceleration, specifically calibration of the ascertained required braking torque or calibration of the drive signal that is generated based on the ascertained required braking torque.

Abstract: An actuator for an elevator system, which actuator can adopt an activated state and a released state, has a restoring element. The actuator is brought from the released state into the activated state by the restoring element. The restoring element is made of a shape memory alloy. At a first temperature, the restoring element adopts a first length, and a second length at a second temperature. After the actuator has been released, the restoring element changes from the first length into the second length, and back into the first length. In this way, the restoring element returns the actuator to the activated state.

Abstract: A method and a system for determining the position of an elevator car of an elevator system, which car is arranged for travel in an elevator hoistway, includes equipping the elevator car with an acceleration sensor that registers acceleration data in a computing unit, calculation by the computing unit of the current position and/or of the velocity of the elevator car, and equipping the elevator system with an image-recording unit, which unit records recorded images of the elevator hoistway. The computing unit compares the recorded images with current mapping images of the elevator hoistway to determine an image-based current position of the elevator car. Finally, the computing unit undertakes a recalibration of the current position using the image-based current position.

Abstract: An unlocking device with an actuator releases a safety cover of a maintenance opening for opening. The locking device has a safety circuit for actuating the actuator. The safety circuit includes at least one first switching contact and a second switching contact arranged in series, wherein the actuator in a closed state of the first and the second switching contacts is connected by the safety circuit with a power source, and the first switching contact can be switched by a control unit. One or more of the unlocking device can be used in an elevator system.

Abstract: An elevator installation has at least one shaft door and a monitoring device for monitoring movements for opening the shaft door, the monitoring device comprising a first, energy-autonomous counting device for counting the movements, which independently of an intact power supply increments a first count value in the case of one of these movements, and a second counting device for counting the movements, which when the power supply is intact increments a second count value in the case of one of these movements, and a comparison circuit which calls up and compares the first and second count values and can generate a signal based on the comparison of the count values.

Abstract: A method for forming a guide structure in an elevator shaft provides a guide structure configured to guide an elevator car during vertical travel in the elevator shaft. The method includes the following steps: moving a tool, such as a milling tool, vertically along the elevator shaft, wherein the tool is precisely positioned with respect to the horizontal position thereof within the elevator shaft, and forming the guide structure by removing material on a shaft wall of the elevator shaft using the tool.

Abstract: A method for monitoring an elevator system utilizes a mobile terminal device having at least one sensor to collect measurement values in an elevator car. The mobile terminal device is carried by a passenger of the elevator system. The collected measurement values are transmitted by the mobile terminal device to a central evaluation unit where they are evaluated. The mobile terminal device activates a measurement mode when it detects that it is located in a region of a shaft door of the elevator system.
