A search tool graphical user interface comprises search criteria selected by an operator of the search tool. The present invention is applicable to, for example, an active matrix type image display device using an organic EL device, and a short circuit location between wiring patterns is able to be repaired. The coverwheel assemblies are supported and transported on carriers that are provided with clamping mechanisms. If the cable modem determines no incoming data transmission activity, the cable modem begins to query the status of the consumer premise equipment.
