Apparatus for voltage regulation circuits and related operating methods are provided. In an example, the clip device has a base having a first and second side. The fixed component detects the mobile component presence within proximity range using a short range wireless connection. The paint is then discharged from the apparatus through a spray nozzle. In a case where the encoding rate 13<R\u226623, one bit is set. The polishing apparatus has a polishing section having a turntable with a polishing surface and a top ring for holding a substrate and pressing the substrate against the polishing surface to polish a surface having a semiconductor device thereon, and a cleaning section for cleaning the substrate which has been polished.
