A diaphragm pump includes a pressure sensor disposed in the housing thereof, and which is used as an expansion tank for protecting the pressure sensor. Molluscs are held in holders by one of their shells, illustratively the bottom shells, and are moved between a series of processing stations. A data processing system displays within a display device at least first and second windows. A data path is then selected that has a failure probability lower than the failure probability of other data paths of the plurality of data paths and the computer IO device is accessed using the selected data path. The method includes jointly adapting bit rates of the respective data streams being transmitted in accordance with the available bandwidth, a general target time, and a quality measure. This yields superior surface wave noise mitigation, with reduced likelihood of attenuating signal.
