A mobile station apparatus efficiently switches coding schemes when coding both information indicating an ACKNACK and first control information. In some implementations, the case may be made from a flexible viscoelastic material and the biometric monitoring device may be slipped into a receptacle in the case through an opening in the case; the opening may become distended during the insertion of the biometric monitoring device. A corresponding sensor circuit is electrically coupled to the opposed electrodes and adapted to sense an instantaneous capacitance of the capacitor to determine the amount of toner that exists between the opposed electrodes. The method may also include determining a hand location using the determined threshold for the extracted hand region in the at least one captured frame. A processor is provided for executing the boot program upon startup of the printer. Further, the method includes assigning the new Cell ID to the base station.
