| 20120077452 | IP2 CALIBRATION METHODS AND TECHNIQUES - Some embodiments of the present disclosure relate to improved techniques for performing IP2 calibration in receivers having two complementary data paths (e.g., i-data path and q-data path). In these techniques, one of the two data paths (e.g., the i-data path) is used to generate a reference signal for the other data path (e.g., the q-data path), and/or vice versa. The other data path then performs calibration using the reference signal. Compared to previous techniques (which required separate, dedicated circuitry for generating a reference signal), the inventive techniques reduce the amount of circuitry and correspondingly reduce the manufacturing costs and power consumption. This is because the inventive techniques use the existing circuitry in complementary fashion during calibration (e.g., during calibration an i-data path generates a reference signal for a q-data path, and vice versa). | 03-29-2012 |

| 20090304369 | DRIVE AND EVALUATION UNIT - The invention relates to a drive and evaluation unit for displacing an object to be displaced, particularly for raising and lowering a side window in a motor vehicle. The drive includes a commutator motor with a stator having two diametrically opposed permanent magnets. The magnets have cross-sectional shapes of a respective peripheral contour segment, having a radial inner peripheral contour segment which encompasses an armature over a respective inner peripheral angle. The armature is provided with ten grooves spaced around its periphery for holding armature windings that are configured as lap windings. The evaluation unit includes a device for determining the rotational position of the armature by evaluating the ripple count of the armature current. According to the invention, the armature windings are configured as short pitch windings, and the inner peripheral angle of the radial inner peripheral contour segment of at least one of the magnets is between 101° and 111°. | 12-10-2009 |
