Compositions and methods for modulating melanogenesis by modifying tyrosinase palmitoylation are provided. The devices are operatively configured for suspending and displaying articles, such as tags, signage, clothing, and baseball caps containing ferrous elements. At least one torsional flexure and at least one hinge flexure can cooperate to provide comparatively high lateral stiffness between the outer frame and the movable frame and can cooperate to provide comparatively low rotational stiffness between the outer frame and the movable frame. A TCPIP communication command is used to input or output image data, ensuring reliable transmission. Accordingly, because the frequency changes are concentrated in the period of pulse transmission, even reflections ‘from a close object, where the time delay between the source signal and the reflection is very short, will cause a high beat frequency.
