Abstract: A field device that communicates in accordance with Ethernet signaling is provided. The field device is powered by virtue of its Ethernet connection. The field device preferably includes a feature board that includes an Ethernet network connection and a field device connection. The feature board is configured to power the field device with power received through the Ethernet network connection. The feature board interacts with the field device using a process industry standard communication protocol. A method of operating a field device is also provided.

Abstract: A portable power source having a battery that is electrically connected to a power circuit that is configured to generate a higher output voltage than the voltage generated by the internal battery. The power circuit is electrically connected to a connection device that distributes the higher output voltage to an external battery source. The power source also includes a case that includes an integral handle for carrying the power source. The handle is formed into the case that includes an internal compartment that is covered by a movable door formed into the case. The door is movable between open and closed positions and arranged and configured to open a switch when the door is in the closed position and close the switch when the door is in the open position. The switch controlled by the movable door controls the application of power to all components comprising the power circuit.
