  • Patent number: 7288931
    Abstract: In a method of determining residual error compensation parameters for a magnetoresistive angle sensor providing a first measurement signal depending on a rotational angle the step of generating a plurality of value pairs for a plurality of rotational angle values is provided, wherein each value pair has a rotational angle value and an associated measurement signal value. The method further includes ascertaining a sinusoidal fit function the course of which is adapted to the plurality of value pairs. Finally, residual error compensation parameters can be generated from a difference between the ascertained sinusoidal fit function and the associated measurement signal values of the measurement signal for the plurality of rotational angle values.

  • Publication number: 20070200564
    Abstract: A magnetic field sensor has a first sensor with an output for a first signal indicating a magnetic field acting in a plane, and a second sensor having an output for a second signal indicating a component of the magnetic field perpendicular to the plane. The first sensor and the second sensor are applied on a common substrate by means of planar process steps.

  • Patent number: 7203618
    Abstract: A method for adjusting a determination rule for an error compensation of an angle sensor is designed to detect a first component of a direction along a first axis and a second component of a direction along a second axis, and to determine an angle of the direction according to the determination rule based on the first and second components. The method includes: detecting values of component pairs consisting of two predetermined components for the calculation of offset and/or amplitude and/or axis-angle errors. One variant consists of entering the component value pairs into an ellipse equation system, determining at least one ellipse coefficient from the ellipse equation system, and adjusting the determination rule depending on the one determined ellipse coefficient or the plurality of determined ellipse coefficients. A further variant is the determination of selected points, extremums or zero points for the determination of the offset and/or amplitude and/or axis-angle errors.

  • Publication number: 20040210684
    Abstract: An improved method and a corresponding device for adapting the data rate of a data stream by using a FIFO memory (1) into which data packets of the data stream are written at a first data rate and from which the data packets are output at a second data rate, is proposed. According to the invention a certain pause (TP) is inserted after each output data packet until the next data packet is output. In the event of a no-load of the FIFO memory (1) an additional pause (TFE) is produced, which is detected. In addition, the number of the data packets output between a preceding no-load and the current no-load of the FIFO memory (1) is ascertained.
