Abstract: An inter-transmission device connection registration device 30A includes a storage unit 31 that registers connection information of a case where transponders 12a to 13n and photo couplers 14a to 14n as divided various transmission devices are connected through a port o and a port i, a light emission instruction unit 33 that provides a light emission instruction to the subordinately connected transponders, a transmission/reception detection unit 34 configured to detect a light transmission and a light reception at opposing ports o and i1 between transmission devices, e.g., the transponder 12a and the photo coupler 14 in accordance with the light emission instruction, and a registration control unit 35 that performs a control of registering, in the storage unit 31, connection information W2a of the port o on a light transmission side and the port i1 on a light reception side that are detected.

Abstract: A reinforcement device may include at least one elongated reinforcement body having a longitudinal axis and at least one foamable member that produces a foamed product when heated. The foamable member is preferably disposed along the longitudinal axis of the reinforcement body so that the foamed product will extend along the longitudinal axis of the reinforcement body. Preferably, the foamed product bonds the reinforcement body to a hollow structural member in order to reinforce the hollow structural member.

Abstract: A reinforcement device 10, 110 may include at least one elongated reinforcement body 11, 111 having a longitudinal axis and at least one foamable member 30, 130 that produces a foamed product 35, 135 when heated. The foamable member 30, 130 is preferably disposed along the longitudinal axis of the reinforcement body 11, 111 so that the foamed product 35, 135 will extend along the longitudinal axis of the reinforcement body 11, 111. Preferably, the foamed product 35, 135 bonds the reinforcement body 11, 111 to a hollow structural member 1 in order to reinforce the hollow structural member 1.
