A securing apparatus includes a receiving portion, and two resilient arms. The first circuit may be configured to generate one or more command signals, a read data path control signal and one or more write data path control signals in response to an integrity protection control signal and one or more arbitration signals. Each of the nozzle opening arrays has plural nozzle openings. The image processing device is adapted to generate at least one three-dimensional image data set of the object volume based on obtained image data and is further adapted to compute a transfer function range for use in volume rendering. The second substrate includes a third electrode that faces the first and second electrodes.
