Abstract: An integrated fuel management system can include a switching unit coupled to an electric vehicle (EV) charging station, a computer system, a first electronic unit, and a second electronic unit. The first electronic unit can be coupled to the switching unit and operable for providing state information for the EV charging station to the computer system. The second electronic unit can be coupled to a fueling station for types of vehicles that use fuel and operable for providing state information for the fueling station to the computer system. Further, the computer system can be operable for displaying the state information for the EV charging station and for displaying the state information for the fueling station.

Abstract: A fueling system can include an electric vehicle (EV) charging station and a non-charging fueling station for fueling vehicles other than EVs. The EV charging station includes a first control unit, a switching unit, and output connections that can be connected to EVs. The non-charging fueling station includes a second control unit and, for example, a liquid fuel pump. An integrated fuel management system is in communication with the EV charging station and the non-charging fueling station. The switching unit can direct a charging current from an input power supply to an output connection in response to commands from the first control unit that are issued according to a charging procedure. The first control unit can send state information for the EV charging station to the integrated fuel management system. The second control unit can send state information for the non-charging fueling station to the integrated fuel management system.

Abstract: A method and apparatus for ventilating a building comprises an air duct extending between an attic and a basement or crawl space through an occupiable portion of the building. The duct has no openings within the occupied portion of the building, the occupied portion being substantially isolated from the transfer of air to and from either the attic or the basement or crawl space. An exhaust fan extracts hot air from the attic to the atmosphere, while a duct fan replaces the air in the attic with cool, humid air from the basement or crawl space. The crawl space or basement is replenished through exterior openings in the building to the atmosphere. A thermostat and humidistat control the operation of the fans in response to environmental conditions within the attic. A detector can shut down the fans if radon is detected in the duct.
