Abstract: A system comprising a vehicle on-board computer; and a wireless transponder device coupled to the vehicle on-board computer. The system performs a variety of functions because of its ability to transmit and receive data from other transponders which may be remote from the vehicle or located in the vehicle at a location spaced apart from the system. Remote transponders are spaced apart from the vehicle. The remote transponders can be positioned, for example, at a gas station, toll booth, service center, dealership, parking lot, or along a roadside.

Abstract: A button-type battery includes: a) an anode; b) a cathode positioned adjacent to the anode; c) a separator and electrolyte between the anode and the cathode; d) a conductive first terminal housing member in electrical contact with one of the anode or the cathode, the first terminal housing member having a surrounding periphery and a concave central portion intermediate of its surrounding periphery; e) a conductive second terminal housing member in electrical contact with the other of the anode or the cathode, the second terminal housing member having a surrounding periphery and a concave central portion intermediate of its surrounding periphery which is opposingly concave to the concave central portion of the first terminal housing member; and f) the first and second terminal housing members being insulatingly joined and sealed at their respective peripheries to form an enclosed housing which retains and protects the anode, cathode, separator and electrolyte, with the concave central portions of the first and
