A combined camera and printer assembly includes a support structure suitable for housing electronic components. The device is embodied in the form of the accumulator component which operates as a throttle on a fluid flow and is inserted between internal elements of the accumulator and a hydraulic network to which the accumulator is connectable. The write operations are preferably transmitted across the reflective memory channel using a protocol that provides for error checking, acknowledgements, and retransmissions. Respective third storage values are re-read from a subset of the memory cells that includes the memory cells holding the suspect storage values.
