  • Publication number: 20120274286
    Abstract: A method for improving the performance of a traction battery during a driving start phase of an electric vehicle. A driving start point in time at which the driving start phase begins is provided. A temperature of the traction battery is detected. This temperature is compared with a minimum operating temperature, and the traction battery is heated if the comparison reveals that the temperature of the traction battery is below the minimum operating temperature. The heating takes place with a temperature increase which provides a temperature of the traction battery at the driving start point in time, which is no lower than the minimum operating temperature.

  • Publication number: 20100101522
    Abstract: The invention relates to a method for positioning a crankshaft of a turned-off internal combustion engine of a motor vehicle, wherein the crankshaft is rotated into a desired target position for the subsequent start of the internal combustion engine by means of an electric starter motor having a free wheel. The invention provides that at least one characteristic curve and/or characteristic value of a correlation between a covered rotational distance of the crankshaft and a position of the angle of rotation is determined at a standardized pulsed current duration of the starter motor for a defined operating case, that the current position of the angle of rotation of the crankshaft is determined, and that at least one estimated pulsed current duration is applied to the electric starter motor as a function of the determined position of the angle of rotation of the crankshaft and the target position and the characteristic curve/characteristic values.

  • Patent number: 7003141
    Abstract: Identification of a fingermark is performed by obtaining for a fingermark a fingermark image, storing reference fingermarks in a databank, comparing the obtained fingermark image with the reference fingermarks for identification, before the identification determining for each reference fingermark in comparison with the obtained fingermark image a similarity degree, sorting the reference fingermarks in the databank in accordance with the similarity degree, and performing the identification of the fingermark beginning with the reference fingermark which leads to the greatest similarity degree.

  • Patent number: 6826295
    Abstract: A method for determining reference points in a fingerprint image is used for determining similarity values using a determination of orientation patterns and a comparison with reference orientation patterns, in which the similarity values are compared with a first threshold value to determine whether a reference point is identified or not. Whorl, delta or core points are identified as core points. Both a linear and a nonlinear reference orientation pattern are used for core points. The orientation pattern for an image area is converted into a vector field for comparison with the reference orientation patterns. A scattering is computed from the spectral power density, which is determined for computation of orientation patterns, and severely distorted image areas are thereby eliminated from the determination of reference points.
