Patent number: 6877488Abstract: An integrated fuel management system and method for controlling the fuel storage and delivery in a vehicle. The fuel management system includes a fuel storage tank for storing fuel in a vehicle, a vapor collection canister located within the fuel storage tank, a vent actuator coupled to the vapor collection canister for venting gas from the canister during a vent operation, and a purge actuator coupled to the canister for purging fuel vapor from the canister during a purge operation. A variable speed fuel pump is disposed within the fuel storage tank for delivering fuel to a fuel delivery line for an engine. The fuel management system has a controller provided in a module disposed in communication with the fuel for controlling the amount of fuel pumped with the variable speed fuel pump to deliver fuel to the fuel delivery line and further control the purge and vent actuators.Type: GrantFiled: May 29, 2002Date of Patent: April 12, 2005Assignee: Nartron CorporationInventors: John Washeleski, Randall L. Perrin, John E. Mitchell

Patent number: 6835090Abstract: A sealed electrical assembly that includes a housing having an opening at an end. An electrical device is positioned in the housing. The electrical device includes a lead that extends out of the open end. A cover is positioned within the opening. The cover includes a plate portion and a tab portion spaced apart from the plate portion. The tab portion extends into a cutout in the housing that is located between the plate portion and the housing end to position the cover with respect to the housing. A sealant is disposed around a perimeter of the plate portion to provide a seal between the cover and the housing. A portion of the sealant is disposed in a space between the cutout and the plate portion to prevent leakage through the cutout.Type: GrantFiled: August 20, 2003Date of Patent: December 28, 2004Assignee: Delta Systems, Inc.Inventor: Michael Eric Liedtke
