Mixtures of an oxidizer and a high pressure fluid are produced by adsorbing an oxidizer in an adsorption bed and then desorbing the oxidizer with a high pressure fluid. The method further includes receiving the packet at the button actuator, decoding the packet in a digital processor to derive the button control signal, and controlling a motor to move a physical actuator between a neutral position and a button press position. The drill bits have varying diameters that correspond to the sizer instruments.
