Computer programs (also called computer control logic) are stored in main memory 806 and/or secondary memory 808. Computer programs may also be received via communications interface 820. Such computer programs, when executed, enable the computer system 800 to implement the present disclosure as discussed herein. In particular, the computer programs, when executed, enable processor 804 to implement the processes of the present disclosure, such as any of the methods described herein. Accordingly, such computer programs represent controllers of the computer system 800. Where the disclosure is implemented using software, the software may be stored in a computer program product and loaded into computer system 800 using removable storage drive 812, interface 814, or communications interface 820.

In another embodiment, features of the disclosure are implemented primarily in hardware using, for example, hardware components such as application-specific integrated circuits (ASICs) and gate arrays. Implementation of a hardware state machine so as to perform the functions described herein will also be apparent to persons skilled in the relevant art(s).

Conclusion

It is to be appreciated that the Detailed Description section, and not the Abstract section, is intended to be used to interpret the claims. The Abstract section may set forth one or more, but not all exemplary embodiments, and thus, is not intended to limit the disclosure and the appended claims in any way.
