Abstract: A method for testing the function of a driver assistance system of a vehicle, wherein an environment of the vehicle is detected by means of a sensor system, includes the following steps: stimulating the driver assistance system by means of an external stimulation; processing the stimulation in the driver assistance system so that a stimulation response is obtained; transmitting the stimulation and/or information relating to the stimulation to an external reference device and determining a reference response for the stimulation in the external reference device in accordance with a desired state of the driver assistance system; and comparing the stimulation response with the reference response. The invention enables the functionality of a driver assistance system of a vehicle to be tested in a simple and cost-effective manner.
Abstract: Certain aspects are directed to a configuration sub-system for telecommunication systems. The configuration sub-system can include a test signal generator, a power measurement device, at least one additional power measurement device, and a controller. The test signal generator can be integrated into components of a telecommunication system. The test signal generator can provide a test signal to a signal path of the telecommunication system. The power measurement device and the additional power measurement device can respectively be integrated into different components of the telecommunication system. The power measurement device and the additional power measurement device can respectively measure the power of the test signal at different measurement points in the signal path. The controller can normalize signals transmitted via the telecommunication system by adjusting a path gain for the signal path based on measurements from the power measurement device and the additional power measurement device.

Abstract: A container may have a floor, a ceiling, a first side wall, and a second side wall, a first end wall, and a second end wall. The first side wall, the second side wall, the first end wall, and the second end wall may be formed from a container wall for reducing an effective radar cross section of the container. The first side wall and the second side wall in a longitudinal direction of the container mid-height between the floor and the ceiling may be foldable inward into the interior of the container. The first side wall may include a first cladding board that is permeable to radar rays and reduces the effective radar cross section of the container. The first cladding board may have a reflective agent that reflects radar rays and can be aligned to be at least partially inclined relative to a plane of a main extent of the first cladding board.
