Abstract: A monitoring unit which is configured to monitor a patient during an operation of a high-frequency surgery device, wherein the high-frequency surgery device is configured to separate and/or coagulate biological tissue by means of high-frequency electrical energy, wherein the monitoring unit has: measuring electrodes which are disposed in a periphery of the patient, and an evaluation and control unit which is configured to impress a predetermined measuring alternating voltage or a predetermined measuring alternating current on the measuring electrodes, and to monitor an impedance decreasing between the measuring electrodes and to monitor a time curve of the impedance and/or to monitor a temporal change thereof.

Abstract: A controller of a motor vehicle comprises a drive motor, wheels, braking devices for the wheels, said braking devices being separately controllable by the controller, an ambient sensor, a driving status sensor and a steering system. For increasing the driving stability, a steering angle is determinable by the controller from signals of the ambient sensor and of the driving status sensor, said steering angle providing a stable driving status in addition to a targeted braking of the wheels, and the steering angle is adjustable at the steering system in order to keep the motor vehicle on the paved road, in particular when driving along a curve, so that the motor vehicle remains on an intersecting plane of the possible dynamic vehicle area ahead with an actual road without skidding or colliding with other obstacles.
