Embodiments relate generally to wearablemobile computing devices and computer software configured to perform image processing, including transformation of images of characters into data representing characters. The MAC method includes the steps of extracting, performing, determining, a first transmitting step, and a second transmitting step. The guide assembly includes an elongated portion having a central axis of rotation, and a distal end that is positioned a radial distance away from the central axis. The user equipment, then, transmits a sounding signal through selected number of transmission antennas according to the antenna designation information of the uplink sounding transmission control information element having the shortest cycle period among the plurality of uplink sounding transmission control information elements. When processing of a sample is complete, an inert gas is supplied into the process gas supply piping so that a pressure in the process gas supply piping is maintained at a pressure higher than a pressure at which a compound of the process gas and a material of an inner wall of the process gas supply piping vaporizes.
