A method and system for sharing protection of a mesh network protection domain are disclosed by the present invention. A crystalline silicon film is formed by indirect heat treatment through a photothermal conversion layer and a buffer layer. The elastomeric tube has opposed open and closed ends with a resealable slit being formed in a central portion thereof. The bridge has a link, together with a first and a second interface. The parameter-calculating section calculates a parameter for the pressure control section based on the information acquired by the information-acquiring section.
