  • Patent number: 8322326
    Abstract: An internal combustion engine (8) has an ignition device, a device for supplying fuel and a device for detecting the rpm of the engine (8). The engine (8) includes a permissible limit rpm (ng) and a control range (A) of the rpm (n) above the limit rpm (ng). A method for operating the engine (8) provides that the rpm of the engine (8) is limited in the control range (A) because of suppression of the ignition in individual engine cycles wherein the rpm (n) lies above a control rpm (na) lying in the control range (A). In the control range, and to improve the exhaust-gas values, the noncombustion engine cycle ratio (NECR) is adjusted. The NECR indicates the ratio of the number of engine cycles wherein the ignition is suppressed to the total number of ignitions.

  • Patent number: 8308298
    Abstract: The invention relates to an eye surgery microscopy system (1) having an imaging optic (14, 11) for the generation of the image of an object plane (15) and having an electronic image sensor (22), which detects the image of the object plane (15) and is connected to a computer unit (5) for the computation of the position of the center of a circular structure (44) of a patient eye (16). The computer unit (5) is designed for the computation of the position of a patient eye (16) outside of the center (52) of the circular structure (44) and provided with at least one marking (46, 48). The computer unit (5) determines the position of the at least one marking (46, 48) with reference to the computed center (52) by means of image processing via correlation with a comparison information, and an angular position of the at least one marking (46, 48) with reference to the computed center (52) by means of image processing.

  • Patent number: 8299442
    Abstract: A particle beam apparatus has an optical axis (OA), an illuminating system (1, 2, 3, 4) for illuminating an object, which is positioned in an object plane (7), with a beam of charged particles and an objective (6) for imaging the illuminated object. The beam of charged particles is split at the object into a null beam and higher diffraction orders. The illuminating system is so configured that it generates an annularly-shaped illuminating aperture in a plane Fourier transformed to the object plane (7). A phase-shifting element (9) is mounted in a focal plane (15) of the objective (6) or in a plane conjugated thereto. The focal plane (15) faces away from the object plane (7). The phase-shifting element can be an einzel lens having two outer electrodes and one or several inner electrodes disposed therebetween when seen in the direction of the optical axis. The phase-shifting element can have an additional electrode at or near the optical axis.

  • Patent number: 8267435
    Abstract: A charge-air hose assembly includes a charge-air hose (2) for connecting to a pipe stub (4). The charge-air hose (2), in the assembled position, is pushed into the pipe stub (4) in such a way that overpressure occurring in the charge-air hose (2) presses the charge-air hose (2) radially outward against the radial inner wall (6) of the pipe stub (4). The charge-air hose (2) is assigned a latching device which, during the insertion of the charge-air hose (2) into the pipe stub (4), latches with the pipe stub (4) so as to axially fix the charge-air hose (2) to the pipe stub (4) in a predetermined axial position of the charge-air hose (2) relative to the pipe stub (4).

  • Patent number: 8240645
    Abstract: The invention relates to a bearing, in particular a chassis bearing for the rear axle of a motor vehicle, with an outer bearing sleeve, an inner bearing sleeve, at least one elastomer body arranged between the outer and inner bearing sleeves and two chambers which are arranged laterally opposite each other on the outer bearing sleeve. The chambers each have an adjusting element. The adjusting elements are displaceable. When subjected to pressure, the adjusting elements are displaced inwardly against the inner bearing sleeve. The adjusting elements can be clamped in their axial position by clamping rings which can be reduced in size radially, for example by means of air pressure. The inner bearing sleeve is thereby fixed and the rigidity of the bearing increased.

  • Patent number: 8235525
    Abstract: The invention relates to a novel artificial intraocular lens (IOL) and a method for improving such a lens in the field of ophthalmology, with surface shape modifications that differ from perfect spherical geometries. The intraocular lens takes into account the natural optical configuration of the human vision apparatus, for example, visual axis tilt and pupil decentration. In addition, the method accounts for potential positioning errors caused by implantation and surgery effects.
