  • Patent number: 8922221
    Abstract: A method of detecting a short circuit affecting a sensor, at least one terminal of the sensor being connected to a bias resistor, includes: applying to at least one bias resistor at least one test bias voltage having at least one predefined characteristic that is different from a corresponding characteristic of a nominal bias voltage of the resistor; measuring a resulting differential voltage across the terminals of the sensor; and as a function of at least one characteristic of the measured differential voltage corresponding to the predefined characteristic of the test bias voltages, determining whether the sensor presents a short circuit.
    Type: Grant

    Date of Patent: December 30, 2014
    Assignee: Sagem Defense Securite
    Inventors: Bertrand Lacombe, Nicolas Geneste
  • Patent number: 8872530
    Abstract: A method for correcting measurement of a voltage across output terminals of a sensor, the sensor configured to be assimilated with an assembly including a generator and a series resistance, each of the output terminals being respectively connected to a pull up/down resistor. The method includes: evaluating the series resistance of the sensor, including measuring first and second voltages across the output terminals when first and second bias voltages are applied on each pull up/down resistor; evaluating the series resistance from the first and second voltages; and correcting, from the series resistance, a voltage measured across the output terminals of the sensor to infer therefrom a corresponding voltage generated by the generator.

  • Patent number: 7741819
    Abstract: In order to reduce the cost of a chopping converter supplying a continuous voltage at the terminals of a load (Z), a circuit with two windings (Lp, Ls) and a single magnetic core is proposed, according to the present invention, which enables the cost and the size of the circuit to be reduced. It is then necessary to add two diodes (D3, D4) to the circuit, but these elements are inexpensive and of small size.
