A method and apparatus for achieving multicolor displays using an integrated color chip is provided. A required deceleration to bring the elevator car to a standstill within a next-possible exit zone in the special operating mode is calculated, furthermore a stopping of the elevator car is detected if a sudden change in the braking force or the acceleration is established and the braking force of the braking device is set to a holding force when the stopping is established. The control circuit is disposed on the opposite side of the support than the light modulating elements. The angle of inclination is selected so that a component of excitation radiation incident upon, but not absorbed by, the at least one sample substance is scattered or reflected to reduce excitation radiation from reaching the detection beam path. A thermal chromic printed layer having at least a part disposed on the bag, and the printed material is mixed with a thermal chromic dye, such that the thermo chromic material will change the color of the printed layer for a visual indication as the temperature rises or drops. The network provides redundancy in case any of the digital generation units.
