A method is provided for supplying a component to a pick-up position located near a stop by means of a component supplying device. The vibrators are arranged in proximity to vibration transmitters, corresponding to holding parts of a steering wheel, so that they are controlled with desired vibration intensity and vibration start timing in response to drive signals from the controller. The assembly of electric motor with encoder further includes an output signal cable connected to the circuit board of the encoder and including a signal wire and a shield member, and a grounding mechanism electrically connecting the shield member of the output signal cable to the motor housing for grounding purposes. The system will ask the passenger for, and receive from the passenger, the number of bags they intend to check-in for the flight. A fluid path is provided through the threaded connection for the flow of fluid between the air spring and auxiliary reservoir.
