  • Device, ammeter and motor vehicle
    Patent number: 6940265
    Abstract: A device, an ammeter and a motor vehicle, having a first section and a second section of a conductor for the purpose of measuring the electrical amperage in the conductor are described; a first sensor means and a second sensor means being provided; the current flowing in the first section and in the second section generating a useful magnetic field; the first sensor means being provided to measure the useful magnetic field; the second sensor means being provided in a location where the useful magnetic field disappears; the second sensor means being provided to measure a magnetic interference field; and the measurement of the useful magnetic field being correctable by the measurement of the magnetic interference field.
    Type: Grant

    Assignee: Robert Bosch GmbH
    Inventors: M. Henning Hauenstein, Andreas Stratmann, Stephan Ernst, Wolfgang Feiler, Qu Ning
  • Device for defecting a magnetic field, magnetic field measure and current meter
    Patent number: 6861717
    Abstract: A device for detecting a magnetic field, e.g., a magnetic field meter and an ammeter are described, the device having a first lateral magnetotransistor and a second lateral magnetotransistor, and in which the first and the second lateral magnetotransistors are complementary.
