Apparatus including a flow channel defined by a floor, roof, and sidewall structure connecting the floor and roof. The method comprising maintaining the inspiratory flow rate and volume of the patient to a certain value and then administering a medicament aerosol formulation to the patient using a breath activated inhalation device. An opening is formed in a frame, and one end portion of the connecting member is stably fixed to the frame in the opening. The minimum transmission resource unit may be a single channelisation code in a single time slot. The new set of N image frames is used to produce another peak display image. The method comprises determining whether the handover for the UE is possible or not; transmitting handover information to the second Node B if the handover is possible; and transmitting a command to the UE through the first Node B, requesting the UE to hand over to the second Node B if the UE receives a response message indicating that the handover is possible from the second Node B.
