Abstract: A coating structure includes a substrate, a first metal layer, a second alloy layer, a third metal layer, and a fourth alloy layer. The first metal layer is plated on an outside of the substrate and does not include graphite. The second alloy layer is plated on an outside of the first metal layer and is synthesized from graphite and metal. The third metal layer is plated on an outside of the second alloy layer and does not include graphite. The fourth alloy layer is plated on an outside of the third metal layer and is also synthesized from graphite and metal.

Abstract: Methods and systems provide the infrastructure supporting an omniphysical mind or descriptive self supportable by a computing device. The infrastructure includes descriptive information capabilities and special symbols that support the capabilities. For example, a system may include at least one processor and memory storing a database that includes symbols, definitions of symbols, and processing rules. Symbol in the database may represent awareness capabilities, a categorization capability, a decision capability, a safety capability, a report capability, and a self-initiate capability. One special symbol may represent the ability of the system to organize and call the other special symbols that support the infrastructure.

Abstract: The present disclosure provides a method for printing-device monitoring by a printing monitoring server connected to a network, including: receiving identification information of a non-networked printing device and identification information of a host computer sent by the host computer, the non-networked printing device being connected to the host computer and being connected to the network through the host computer; when locally-stored printing device data contains the identification information of the non-networked printing device, determining host-computer identification information corresponding to the non-networked printing device and contained in the printing device data, to be identification information of a previous host computer; and when the identification information of the previous host computer is inconsistent with the identification information of the host computer, commanding the previous host computer stored with the identification information of the non-networked printing device to delete the

Abstract: Embodiments of the present invention disclose a zero-crossing detection method and circuit. The zero-crossing detection method includes: detecting a time point t0 when a mains voltage jumps from a low electrical level to a high electrical level and an adjacent time point t1 when the mains voltage jumps from a high electrical level to a low electrical level at a port of a detection end; and determining, according to the detected time points t0 and t1, a time point t when the mains voltage crosses zero.
