Abstract: A magneto-optic current transformer for measuring a current intensity of an electric current in an electrical conductor includes two light-guide units, each with an input polarizer, an output polarizer and a light guide arranged between the input and the output polarizer. A light-supply device is included which is configured to supply light to the light-guide units on the input side, and an analysis device which is configured to measure a luminous intensity of light output by the light-guide unit at the output side for each light-guide unit and to ascertain the current intensity of the electric current through the electrical conductor from the measured luminous intensities. A polarization axis of the output polarizer of each light-guide unit is rotated through a polarization angle in relation to a polarization axis of the input polarizer of the light-guide unit and the polarization angles of the two light-guide units differ from one another.

Abstract: A glass ring for current measurements includes a glass body, which can be disposed around an electrical conductor and has a light entry surface and a light exit surface. The glass ring allows light which enters the glass body through the light entry surface to circulate completely around the conductor in the glass body by reflection on external sides or outer faces of the glass body, the light exiting from the glass body on the light exit surface. The glass ring is formed of a monolithic glass body. A method for optical current measurement includes using a current flow in an electrical conductor to generate an electromagnetic field around the conductor, by which a polarization of a light beam in the glass ring around the conductor, in particular with a plane perpendicular to the longitudinal axis of the conductor, is changed as the light beam circulates around the conductor.

Abstract: In a method of steering a vehicle by a steering assistance system, a steering-wheel angle of a steering wheel is set by a driver. The steering assistance system checks whether the set steering-wheel angle is maintained during a predefined time period and checks whether the driver has taken the hands from the steering wheel. The vehicle is then operated according to the set steering-wheel angle, when the driver maintains the set steering-wheel angle during the predefined time period, or the steering assistance system is switched off, when the driver has released the steering wheel.
