Abstract: A circuit board structure includes a circuit substrate, a first circuit layer, and a second circuit layer. The circuit substrate has a surface and includes at least one conductive structure and at least one patterned circuit layer. The conductive structure is electrically connected to the patterned circuit layer, and an upper surface of the conductive structure is aligned with the surface. The first circuit layer is directly disposed on the surface of the circuit substrate and electrically connected to the conductive structure. A line width of the first circuit layer is less than or equal to 1/4 of a line width of the patterned circuit layer. The second circuit layer is directly disposed on the first circuit layer and electrically connected to the first circuit layer.

Abstract: A system and a method for controlling a power line network are provided. In the system and the method, a control unit device in every control network generates its own control network identification (CNID) and sends query messages to the other control networks to ensure each CNID is unique in the signal-reachable networks. The system and the method differentiate messages of the local control network from messages of the other control networks based on received signal strength of the messages in order to correctly demarcate multiple control networks.

Abstract: A method for producing a plastic tile includes the steps of: preparing a molding material consisting essentially of a resinous powder, diatom powder, barium sulfate and organo-tin; and injection molding the molding material. The resinous powder contains, by weight, 60% of acrylonitrile butadiene styrene and 40% of polyvinyl chloride.
