    • An injection valve is hydraulically coupled to a high-pressure accumulator in order to supply a fluid. The injection valve has a longitudinal axis, an injection needle, and an actuator. The actuator is designed to act on the injection needle. A pre-defined amount of electrical energy is supplied to the actuator in order to modify an axial length of the actuator in such a way that the injection needle moves out of the closed position. Once the pre-defined amount of electrical energy has been supplied, a first voltage value and a second voltage value are detected and/or determined by the actuator at respectively different pre-defined moments. On the basis of the first and second voltage values, a differential voltage value is determined, on the basis of which a first pressure is determined, which represents a pressure in the high-pressure accumulator.

    • A blind spot sensor system detects and/or classifies objects in a defined monitoring region of a motor vehicle. The blind spot sensor system contains a first device for emitting a first radar beam, and a second device for emitting a second radar beam. The radial visual range of the first radar beam (beam I) inclines counter to a direction of travel of the motor vehicle and the radial visual range of the second radar beam (beam II) is oriented in an substantially vertical manner in relation to the direction of travel such that the visual range of the radar beams (I and II) at least partially overlap and cover, substantially, the monitoring region. At least the first radar beam (beam I) can be actuated in a CW modulation mode and in a FMCW modulation mode. The blind spot sensor is used in vehicles, for example for assisting in lane changing.
