This application describes a system and associated methods for enabling users of video editing, compositing, motion graphics, and other applications to easily store and retrieve presets, have presets modified for compatibility with other applications, share presets with each other, and search for shared presets. These flip-flops enable fine-grained dual supply voltage techniques such as low-swing clocking and clustered voltage scaling. The management system sends the devices animal specific data of only the milking animals which enter, are about to enter, or have entered a zone with which a device is associated.
