The invention concerns a vibration damping device. In one aspect, the method employs a low-level access scheme that enables data to be recovered when high-level interfaces, such as file systems, are damaged. The mounting portion may form a separate space between the mounting portion and the bare cells. A catalyst is disposed on respective surfaces of a plurality of the tubular elements exposed to at least one of the first fluid flow and second fluid flow. The collected scan data is mapped to another set of locations, thus allowing for detection of surface features using fewer scans. Each bit signal type has a time interval that is discernible from respective time intervals of all other bit signal types from among the plurality of bit signal types.
