A radio communication system performs data communication by a backscatter system using absorption and reflection of a received radio wave. Ultrasound may also be applied, if desired. Channels within the array waveguide are coursely aligned to the two or more optical fibers and may be more finely aligned by manual adjustment. The receiving frame has a receiving opening for at least one workpiece to be coated. The coupling of the sealing element with the cup-shaped body andor the piston is friction-fit. If the configuration verification is unable to verify the configuration of storage system, the configuration verification may display an error.
