  • Circuit for processing the output signal from a resistive analog sensor, in particular for the fuel gauge of a motor vehicle, and systems fitted therewith
    Patent number: 5519397
    Abstract: The present invention relates to a circuit for processing the output signal from a resistive analog sensor, comprising firstly a digital filter, and secondly a module forming a digital-to-impedance converter, which filter and module are interposed in series between the output of the sensor and the input of an associated load, the digital-to-impedance converter presenting an output impedance that is variable as a function of the output signal from the digital filter, which is equivalent to the output resistance of the sensor.

  • Display device of the galvanometric or logometric type, including a control circuit in form of an integrated circuit chip
    Patent number: 4835460
    Abstract: The present invention relates to a display device with a winding and pivoting elements, of the galvanometric or logometric type. According to the invention the display device comprises, rigid with its case, a support of electrically insulating material, which carries on the one hand at least one integrated circuit chip serving as a control circuit for the device, and on the other hand a series of strips of electrically conductive material, adapted for connecting the integrated circuit chip and at least one winding of the device and for receiving electrical control signals generated by external circuits.
