Abstract: A piston actuation device for the supply of a pressure medium in a pressure medium circuit of a brake system of a motor vehicle. A piston actuation device includes a piston actuable by a spindle drive to execute a back-and-forth translation movement in the direction of a piston guidance axis. The spindle drive has a spindle nut and a spindle that cooperates with the spindle nut via a screw drive. The screw drive converts a rotation movement of the spindle nut into a translation movement of the spindle in the direction of a spindle movement axis. To transmit the translation movement to the piston, the piston and the spindle are connected to each other in an axially fixed manner. The axially fixed connection between the piston and the spindle includes an articulated joint, which allows for a concentricity deviation between the piston guidance axis and the spindle movement axis.

The deflection unit has a hole mirror having an elongated hole that has a greater extent in a direction of longitudinal extent and a lesser extent in a direction of transverse extent. The direction of longitudinal extent of the elongated hole is oriented orthogonally to the line orientation of the line light source.

Abstract: For each generative model of a set of K generative models that classifies sensor data into K classes, in-distribution samples are sampled from training data as being classified as belonging to the class of the generative model and out-of-distribution samples are sampled from the training data as being classified as not belonging to the class of the generative model. Out-of-distribution samples are also generated from each remaining reciprocal generative model in the set of reciprocating generative models excluding the generative model to provide additional samples classified as not belonging to the class of the generative model. Parameters of the generative model are updated to minimize a loss function to maximize likelihood of the samples belonging to the class, and to maximize the loss function on both the sampled out-of-distribution samples and the generated out-of-distribution samples to minimize likelihood of the samples not belonging to the class.
