Logics and/or operations represented in the flowcharts or described herein in another manner, for example, may be considered as a fixed sequence list of executable instructions configured to realize the logic functions and may implemented in any computer-readable medium for an instruction execution system, device or equipment (for example, a computer-based system, a system including a processing module or other systems capable of reading instructions from the instruction execution system, device or equipment and executing the instructions) to use or for use in combination with the instruction execution system, device or equipment. For the specification, “computer-readable medium” may be any device capable of including, storing, communicating with, propagating or transmitting a program for the instruction execution system, device or equipment to use or for use in combination with the instruction execution system, device or equipment. A more specific example (non-exhaustive list) of the computer-readable medium includes: an electric connection portion (electronic device) with one or more wires, a portable computer disk (magnetic device), a Random Access Memory (RAM), a Read-Only Memory (ROM), an Erasable Programmable ROM (EPROM) or flash memory, an optical fiber device and a portable Compact Disc Read-Only Memory (CD-ROM). In addition, the computer-readable medium may even be paper or other mediums on which the program may be printed because, for example, the paper or other mediums may be optically scanned then edited, interpreted or, when necessary, processed in another proper manner to obtain the program in an electronic manner for storage in the computer memory.
