A semiconductor integrated circuit includes cells, cell rows and potential feeders. In one embodiment of the present invention, a pre-processing thickness measurement of a substrate while the substrate is in one of the polishing stations is taken. The at least one side panel depends from the main covering for providing enhanced covering of the vehicle seat. The product information providing apparatus further includes transmitting means for transmitting to the remote terminal the obtained product information management data concerning the specified product. To prevent patient interference when in use, the control module may also be configured to selectively deactivate.
