Abstract: An automatic backup power controller for aquarium use. When the Backup Box taught by the present invention has normal power applied to it, it energizes the 12-48 volt DC coil and closes the Normally Open side of the relay which sends 12-48 volts through the relay and to the connected pump or power head that is connected to the output port on the Backup Box. When normal power is lost the coil will DE-energize thus opening the Normally Open side of the relay in turn causing the Normally Closed side of the relay to close and send 12-48 volts DC battery power through the Normally Closed side of the relay through the fuse and to the Output connection on the Backup Box. The Output connection on the Backup Box is common to both the Normally Open and Normally Closed terminals on the Relay depending on the state it is in.

Abstract: An automatic backup power controller for aquarium use. When the Backup Box taught by the present invention has normal power applied to it, it energizes the 12-24 volt DC coil and closes the Normally Open side of the relay which sends 12-24 volts through the relay and to the connected pump or power head that is connected to the output port on the Backup Box. When normal power is lost the coil will DE-energize thus opening the Normally Open side of the relay in turn causing the Normally Closed side of the relay to close and send 12-24 volts DC battery power through the Normally Closed side of the relay through the fuse and to the Output connection on the Backup Box. The Output connection on the Backup Box is common to both the Normally Open and Normally Closed terminals on the Relay depending on the state it is in.

Abstract: Real and simulated (virtual) networks are interfaced with one another for carrying out hardware-in-the-loop (HITL) testing and evaluations. A simulated network is modeled at a workstation by running a network simulation or discrete event modeling tool on the workstation. A virtual gateway node is defined in the simulated network, and the gateway node is linked with a network adapter on the workstation. An external real network operating with Internet protocol (IP) is also linked with the adapter. The adapter and the gateway node are configured to (i) translate simulated data packets sent from nodes of the simulated network and designated for the real network, into IP data packets for routing or processing by the real network, and (ii) translate IP data packets sent from nodes of the real network and designated for the simulated network, into simulated data packets for muting or processing by the simulated network.
