The present invention relates to the therapeutic and prophylactic use of C1 inhibitor for preventing, reducing and treating ischemia and reperfusion injury. It includes one or more components andor one or more other service elements. The plurality of partitions are configured to permit each of the data messages to be received at an arbitrary one of the plurality of nodes, and to forward the received data message to one or more of the plurality of nodes which own respective ones of the plurality of partitions responsible for participating in producing one of the desired outputs. Other features and variations can be implemented, if desired. The control signal may be a low voltage signal and may be isolated from the solid-state switch by a control switch, which may be an optocoupler.
