Abstract: A method for processing measurement data from a surveillance of an area into classification scores with respect to a given classification and/or properties of objects in the area. The method includes: providing a point cloud of measurement data that assigns, to each of a plurality of points in space, measurement values of at least one quantity; providing an input grid with a plurality of cells; assigning, based on the point cloud, values of the at least one measurement quantity, and/or of at least one work product derived therefrom, to each cell of the input grid; and processing, by a task neural network, the input grid into an output grid whose cells carry classification scores and/or properties of objects as values.

Abstract: A method for object detection of an object based on measurement data from at least one point-based sensor capturing the object. The measurement data, which are based on a point cloud having a plurality of points and associated features, are processed in that, in a point-based first processing step having at least one processing level, the input-side features of the point cloud are realized as learned features, and are enriched at least by information about relationships between the points, and in a grid-based second processing step having at least one processing level, the learned features are then transferred onto a model grid having a plurality of grid cells, and cell-related output data are then generated. An image detection device, a computer program, and a storage unit, are also described.

Abstract: A radar-based environmental detection system for motor vehicles. The system includes at least one radar sensor for providing location data regarding objects in the environment of the motor vehicle, and including a neural network for converting the location data into an environmental model which represents spatio-temporal object data of the objects. The neural network is conditioned to give priority to outputting environmental models in which at least one predetermined physical relationship between the location data and the object data is satisfied.

Abstract: Improved process for working up diacetone acrylamide solutions, obtained by reaction of acetone or diacetone alcohol with acrylonitrile and sulfuric acid and subsequent dilution and neutralization, in which a) the organic phase obtained subsequent to the neutralization, which comprises the crude diacetone acrylamide, is hydrolyzed by addition of an aqueous alkaline solution in order to remove acrylamide, then b) after phase separation has been carried out, the organic phase, which comprises the crude diacetone acrylamide, is neutralized by addition of an acid, and c) in succession, low-boiling-point byproducts are removed by distillation in the presence of one or more polymerization inhibitors, then t-butylacrylamide is removed by distillation and, finally, the diacetone acrylamide is isolated by product distillation, and d) the diacetone acrylamide thus obtained is converted into its final form.
