Abstract: A device for degassing and/or dehydrating a hydraulic oil includes a flow lance, a flow duct, and a decoupling module. The flow lance includes a restriction site via which the hydraulic oil flows under a high pressure drop. The flow duct is configured as a pipe that is located downstream of the restriction site.

The flow duct has a significantly larger cross section with respect to the throughflow cross section of the restriction site. For a quiet operation of the device, the flow lance is held in the decoupling module via which the flow lance is configured to be fastened in a vibration-decoupled manner to a tank.

Abstract: A method for ascertaining an explanation map of an image, in which all those pixels of the image are changed which are significant for a classification of the image ascertained with the aid of a deep neural network. The explanation map is selected in such a way that a smallest possible subset of the pixels of the image are changed, and the explanation map preferably does not lead to the same classification result as the image when it is supplied to the deep neural network for classification. The explanation map is selected in such a way that an activation caused by the explanation map does not essentially exceed an activation caused by the image in feature maps of the deep neural network.
