Abstract: A method for wireless channel frequency hopping synchronization in a PLC-RF integrated network having a first node, a second node, at least one PLC media and a RF media includes one of following characteristics: the first node uses the PLC media to transmit first frequency hopping data, and the second node receives the first frequency hopping data and then uses the first frequency hopping data to transmit or receive a packet on the RF media; the first node uses the PLC media to transmit second frequency hopping data, and the second node receives the second frequency hopping data and then transmits the second frequency hopping data on the PLC media; and the first node uses the RF media to transmit third frequency hopping data, and the second node receives the third frequency hopping data and then transmits the third frequency hopping data on the PLC media.

Abstract: A continuous method for manufacturing crystallized glass plates includes the steps of melting a raw crystallizable glass material to form molten glass, adjusting the molten glass to have a predetermined viscosity, rolling the molten glass to form a belt of crystallizable glass, and passing the belt of crystallizable glass through a crystallization tunnel so as to form a belt of crystallized glass.
