A panel for an electromagnetic shield includes a light-weight, porous, electrically-conductive core layer of metallic foam having generally parallel opposed surfaces and a face sheet having rigidity properties superior to the rigidity properties of the core layer laminated to a surface of the core layer. The gateway module may be configured to send data from the vehicle bus over the connection to the autonomous driving system, receive a vehicle action request over the connection from the autonomous driving system, and provide the vehicle action request to the vehicle bus for processing by the vehicle components to autonomously drive the vehicle. Additionally, the ex vivo expanded Tregs may provide treatment for inflammatoryautomimmune diseases. A control circuit is situated in parallel with the SCR and is used to control the SCR.
