Abstract: A system and method for providing a firewall system that prevents a computer from being accessed by an unauthorized user via a computer network. The system includes a switch assembly that connects and disconnects the computer from a computer network. The switch assembly is controlled by the types of data transmissions generated by the computer. If the computer generates a data transmission addressed to the computer network, the switch assembly automatically interconnects the computer to the computer network. If the data transmission generated by the computer includes a data request from some point on the computer network, the interconnection with the computer network is held open until the requested data is received. Once the requested data is received, the switch assembly disconnects the computer from the computer network.

Abstract: The NBC (Nuclear Biological Chemical) Water Distribution System for transporting water or just refilling water or other form of liquid into canteens from a water-bull faucet or other types of faucets or a five-gallon water can seems to be possible. The inventive device can fill up a canteen in thirty to forty seconds depending on the pressure that the human hands could squeeze that acts like a water pump into the two connecting devices. The present invention can be used in training or combat environment, which will improve troop welfare due to the present invention and its ability to transfer water.
