A bib for protecting clothing worn by a wearer includes a sheet having front and back surfaces, an adhesive strip located on the back surface of the sheet and configured and dimensioned for adhering the sheet to the wearer, and a sealed package attached to the sheet. The system includes a multi-zone audio system controller having an audio inputoutput selection circuit for selectively regulating the source and distribution of audio signals. A local oscillator signal is applied to the gates of the second and third N channel MOS transistors. At the time of restoration, an parser is used to parse the values from the tags and the configuration manager restores the contents of the internal data structures in the memory of the router to the parsed values in accordance with the corresponding tags. By using interference suppression on smaller sub-bands, interference suppression techniques can be utilized with less computational complexity than when performing interference suppression on the broadband signal as a whole.
