A thermoplastic layer material has at least one odor reducing surface which is treated with a carboxylic acid-based odor control agent, and which is able to withstand insults with an aqueous liquid. The basic input-output system configures the codec device based on the configuration data. As a result, a multicarrier signal including the multiple same bits each having a different frequency is generated. A back-end driver may be enabled to acknowledge the placed offloaded data packets. The adjustable spacer is compressible in a substantially axial direction relative to the at least one beveled disc spring. Some covers include adjustable edge-mounted light seals for eliminating light leaks and unsightly areas.
