  • Patent number: 11287492
    Abstract: A system for determining the position of a pig located inside a pipe including a magnetic field source attached to the pig; at least one magnetic field sensor provided on the outside of the pipe and configured to measure magnetic field parameters; and a processor configured to receive magnetic field parameters from the at least one magnetic field sensor and computing a position of the magnetic field source relative to a given reference position. The method includes: establishing a magnetic field representation of the magnetic field provided by the magnetic field source; in-situ measuring at least two magnetic field parameters outside the pipe with a magnetic field sensor at a measuring position relative to the reference position; computing the source position of the magnetic field source relative to the reference position based on data comprising the in-situ measured magnetic field parameters and the magnetic field representation.

  • Patent number: 6602161
    Abstract: The power train of a motor vehicle employs an electronic control unit which selects the extent of engagement of the friction clutch between the engine and the transmission by way of an electronic or fluid-operated actuator. The throttle valve for the engine is adjustable by the control unit and/or by the accelerator pedal to ensure predictable starting of the motor vehicle from standstill on a road surface having a pronounced slope and/or when the motor vehicle carries a heavy load.
