  • Strain sensor incorporating a steel substrate
    Publication number: 20020166385
    Abstract: A strain sensor ideally suited for use as occupant weight sensors in an automobile is disclosed. The sensor uses stainless steel as a substrate. A portion of this conductive substrate is coated with a dielectric material such as porcelain. Strain sensitive resistors are screened on the dielectric to sense the strain placed on the substrate. This provides a robust and reliable sensor.

  • Fuel system low current rheostat
    Patent number: 6127916
    Abstract: A fuel level indicator system that utilizes a resistor card having an arc-shaped resistive path with a first set of spaced apart conductor lines and an arc-shaped resistive ink material overlying the first set of conductor lines. The first conductor lines are formed at an angle with respect to a radial line drawn from the center of the resistive path arc. The resistor card also has an arc-shaped continuously solid conductor base and a second set of spaced apart conductor lines extending from the base at an angle with respect to a radial line drawn from the center of the arc-shaped conductor base. The system includes a wiper assembly having a pair of spaced apart arms. Each arm has a plurality of parallel fingers extending from one end. One of the fingers on a first arm engages a conductor line on the resistive path and a second finger on the first arm engages an adjacent conductor line along the resistive path.
