  • Fuel level indication assembly
    Patent number: 6951131
    Abstract: A fuel level indication assembly for a fuel tank includes at least one ultrasonic sensor having a drum to emit and receive a sonic signal. The at least one ultrasonic sensor is adapted to be disposed in either one of a liquid fuel and a fuel vapor/air space within the fuel tank to measure a level of liquid fuel within the fuel tank.
    Type: Grant
    Filed: September 4, 2003
    Date of Patent: October 4, 2005
    Assignee: Delphi Technologies, Inc.
    Inventors: Ulf Sawert, Hugh Wesley Ireland, Michael D. Lutton, Mark K. Wolfenden, Daniel Alexander Crawford

  • Ceramic resistor card assembly for fuel sensor
    Patent number: 6681628
    Abstract: A ceramic resistor card assembly for a fuel sensor includes a card portion made of a ceramic material. The ceramic resistor card assembly also includes a first conductive ink disposed on the card portion to form a fuel level portion. The ceramic resistor card assembly further includes a second conductive ink disposed on the card portion to form at least one contact for the fuel level portion. The first conductive ink is void of Silver and the second conductive ink contains Silver.

  • Indicator system
    Patent number: 6021668
    Abstract: This invention includes a combustion engine fuel level indication system operable at 10 mA or lower and without any contact resistance buildup. The present system utilizes a noble metal ink formulation for both contacts of resistive path and a conductive path. The resistive and conductive paths each having angled conductor lines which reduce the overall volume requirement for the noble metal ink composition used to make the paths. The invention also includes a wiper contact having spaced apart parallel tangs or fingers positioned so that a first finger engages a first conductor line along the conductive path and a second finger engages an adjacent conductor line along the conductive path to improve the make brake contact.
