A memory hub having an integrated non-volatile memory for storing configuration information is provided. The objects of the invention are obtained by a device for feeding items to a manufacturing machine, where said device comprises a long flexible film arranged in a roll, said film comprising a first protective layer for carrying each of said items. In one design, spatial state information may be determined for multiple spatial channels on multiple subbands. Working in conjunction with the bladder, but not necessarily part of the fluid pump, is a fixed surface to hold the bladder and repel the driving force.
