Abstract: A method and a device for operating an electronic viewing system (11) of a vehicle, which viewing system (11) allowing the driver to view the claimed travel way or soon to be occupied travel path. The system uses at least two optical sensors (01), an image display unit (10), and a detector device (03), wherein by means of the detector device (03) the motion state of the vehicle can be detected. The selection of the images which are shown on the image display unit (10) and which are generated by the optical sensors (01) can be made dependent on the motion state of the vehicle.

Abstract: A method for the assisted steering, particularly the assisted maneuvering and parking, of a motor vehicle which includes determining a nominal driving path (X) with a starting point (S) and a destination point (Wnominal); providing an output of the nominal driving path (X), and setting the motor vehicle in motion. An actual position (W1) of the motor vehicle is determined, wherein a deviant circular arc (KA) traveled as well as a first (K1) and a second (K2) corrective circular arc are determined if the actual position (W1) deviates from the nominal driving path (X). The second corrective circular arc (K2) is a congruent projection of the deviant circular arc (KA) and ends at the destination point (Wnominal). A corrected nominal driving path (K1, K2) is provided as an output.

Abstract: Telephone calls are handled via the Internet between an interworking unit relating to the calling subscriber and an interworking unit relating to the called subscriber. At least the telecommunications network to which the calling subscriber belongs as well as the interworking units are operated by the same provider. Access by a calling subscriber to the interworking unit and the passing on of the dialed telephone number of the called subscriber to the interworking unit are made dependent on the identification of the call as an Internet telephone call and dependent on the result of an access authorization check. Charging for use of the telephone network and of the Internet for such a call does not commence until the connection is made, as in the case of a call which uses only the telephone network.

Abstract: The invention relates to a measuring device which permits a very simple positioning of cells and vesicles respective of cell membranes on planar carriers. The invention also relates to a corresponding highly efficient method for the positioning and electric characterization of such membranes with a consistently high signal-to-noise ratio. In addition, statements concerning interactions of substances with lipid membranes respective of materials bonded thereon or therein respective of signal transduction mechanisms connected thereto are possible.

Abstract: The present invention is related to an egg obtained from a domesticated bird, in particular a layer, having a lipid fraction balanced in seed and green plant-type &ohgr;6 and &ohgr;3 fatty acids according to the ratio of seeds plant-type &ohgr;6 fatty acids/green plant-type &ohgr;3 fatty acids=1:1±10% and having a lipid fraction is balanced between polyunsaturated and saturated fatty acids according to the ratio of polyunsaturated/saturated fatty acids=1:1±10%. The present invention is also related to a feed composition of exclusive vegetarian origin and suitable for poultry and a method for obtaining such egg from said poultry animals.

Abstract: In a satellite global positioning system, satellite acquisition and location assistance is based upon shared information between a GPS receiver and a remote server. Satellite position is predicted by satellite almanac data.

Abstract: Systems for positioning and/or analyzing samples such as cells, vesicles, cellular organelles, and fragments, derivatives, and mixtures thereof, for electrical and/or optical analysis, especially relating to the presence and/or activity of ion channels.

Abstract: Nucleic acid molecules are described encoding an R1-protein from wheat and methods and recombinant DNA molecules for the production of transgenic plant cells and plants synthesizing a modified starch. Additionally, the plant cells and plants resulting from those methods as well as the starch obtainable therefrom are described.

Abstract: In a method for controlling an electric drive, a controlled variable is adjusted to a desired value. To protect the electric drive, the controlled variable is first adjusted to the desired value in a precise manner. Thereafter, the control operation is interrupted, AND the difference between the controlled variable and the desired value is check continuously to see whether it exceed a preset threshold. Interruption of the control operation is terminated when the threshold has been reached or exceeded.

Abstract: A system and method for communicating data between a user and a receiver over a telecommunications network is disclosed in which the data relates to filing information for applications relating to the protection of intellectual property. The method includes the step of the receiver initially registering the user to communicate the application data over the network to the receiver. Thereafter, the user transmits data to the receiver relating to the intellectual property application via the network. The receiver verifies the completeness of the transmitted data from the user and, thereafter, confirms receipt of the verified data over the network to the user.

Abstract: The invention enables a telephone subscriber to be advised via his telephone line of the arrival of a new e-mail. This is achieved by the e-mail server informing the point of presence (POP) of a subscriber to the Internet of the presence of mail, the POP passing this information to the local exchange of the subscriber, which in turn informs the subscriber of the presence of mail.

Abstract: The invention relates to a detector for detecting electrically neutral particles. The detector has a housing (10) filled with a counting gas. A converter (22) in the housing (10) generates conversion products as a result of the absorption of the neutral particles. The conversion products generate electrically charged particles in the counting gas, and a readout device (19) detects the electrically charged particles. A device (18) generates an electrical drift field for the electrically charged particles in a region of the volume of the counting gas so that at least some of the electrically charged particles drift toward the readout device (19). The converter device (22) is of charge-transparent design and being arranged in the detector housing (10) so that the drift field passes through at least part of this device.

Abstract: Methods combining the creation of small bilayer membranes with the fusion of native cell membrane vesicles into those bilayer membranes. By placing a voltage gradient across the lipid bilayer and recording the transmembrane current, the activity of some membrane proteins, such as ion channels, can be analyzed. The methods permit access to a large variety of membrane proteins. The native vesicles may be derived from a variety of cells and intracellular organelles, and as the native cell membrane vesicles may be stored at low temperatures over long periods, the methods reduce the need to maintain cell cultures or obtain primary cells. Fluorescence measurements also may be performed on the bilayer membranes.

Abstract: The invention relates to non-surgical methods for treating cervical or vaginal neoplasia including cervical intraepithelial neoplasia, intraepithelial neoplasia, vulvar intraepithelial neoplasia and ano-genital warts. The treatment, which utilizes an effective amount of indole-3-carbinol and/or diindolylmethane, is effective whether or not the patient is also infected with human papillomavirus, the most common sexually transmitted viral disease in the United States and a known risk factor for both cervical intraepithelial neoplasia and cervical cancer.
