  • Patent number: 10081834
    Abstract: The present invention is directed to sequencing of nucleic acids. A method is provided for sequencing based on immobilized nucleic acid on a surface. Advantageously, a long range detection mechanism is used for detecting, whether a nucleotide provided to the substrate of a biochip has been incorporated into the immobilized template nucleic acid. Various different alignment means are provided by the present invention which can be used for facilitating a rigidly locking of the orientation of the DNA complex, which complex comprises the template nucleic acid, the primer and the capture nucleic acid. Various different linker systems may be used to immobilize the DNA complex at a first and a second strand end, such that the desired alignment of the DNA complex is achieved. Also co-adsorbed molecules on the substrate surface can be used for such an aligning measure.

  • Patent number: 7117904
    Abstract: A device for measuring the filling level of a fuel tank, in particular for motor vehicles, having two openings for installation of a filling connection and a pump unit, and a film sensor provided with an electric connecting cable which can be connected to a display device through the pump unit. The film sensor is embedded in a protective tube which is provided with inlet openings for the fuel. The protective tube is mounted on the filling connection at the side and can be inserted jointly with it into the respective opening in the fuel tank.

  • Patent number: 6536792
    Abstract: A drive-away blocking device is provided for motorcycles having a side support. A sensor, which is mounted on the vehicle and has a linearly guided distance sensing device, and a control component, which is rigidly connected with the swivellable side support and which, at a site eccentric with respect to the axis of rotation of the side support, is connected by way of a restricted guidance with the distance sensing device of the sensor, are provided. In the operational support position of the side support, the sensor emits a signal to the electric or electronic engine control unit to prevent a driving-away of the motorcycle.
