Technology is disclosed for discovering d\xe9cor harmonized with a d\xe9cor style. Some embodiments of the present invention provide volume control circuits for use in electronic devices. Application to sensor conditioning. The code word has a construction that defines a plurality of paths associated with an intersymbol interference environment of the communication channel, wherein the code word achieves a diversity based upon the number of transmit antennas and the number of ISI paths. The imprinted pattern is transferred to the second substrate to form densely-spaced holes in the substrate. This impulse becomes increasingly severe as the wearer moves farther away from the boundary point.
