Abstract: This document describes radar tracking with model estimates augmented by radar detections. An example tracker analyzes information derived using radar detections to enhance radar tracks having object measurements estimated from directly analyzing data cubes with a model (e.g., a machine-learning model). High-quality tracks with measurements to objects of importance can be quickly produced with the model. However, the model only estimates measurements for classes of objects its training or programming can recognize. To improve estimated measurements from the model, or even in some cases, to convey additional classes of objects, the tracker separately analyzes detections. Detections that consistently align to objects recognized by the model can update model-derived measurements conveyed initially in the tracks. Consistently observed detections that do not align to existing tracks may be used to establish new tracks for conveying more classes of objects than the model can recognize.

Abstract: The invention relates to a method for optimizing a yarn production process in which foreign materials (90) are monitored in a textile fiber formation (9). The textile fiber formation (9) is illuminated with electromagnetic radiation from at least two color ranges. The foreign materials (90) are classified into different color classes according to their colors. If a sufficiently large random sample with classified foreign materials (90) is available, a frequency distribution of the foreign materials is determined for the color classes and compared with a reference frequency distribution. If the determined frequency distribution deviates from the reference frequency distribution, at least one of a set of multiple optimization actions is performed, e.g., a warning signal is output.

Abstract: This document describes methods and systems directed at history-based identification of incompatible tracks. The historical trajectory of tracks can be advantageous to accurately determine whether tracks originating from different sensors identify the same object or different objects. However, recording historical data of several tracks may consume vast amounts of memory or computing resources, and related computations may become complex. The methods and systems described herein enable a sensor fusion system of an automobile or other vehicle to consider historical data when associating and pairing tracks, without requiring large amounts of memory and without tying up other computing resources.

Abstract: The disclosure relates to a camshaft adjustment system comprising a hydraulic camshaft adjuster having a stator and a rotor forming at least one working chamber. The at least one working chamber is divided into a first sub-chamber and a second sub-chamber. The sub-chambers interact with a control valve controllable via a first actuator.

A second actuator actuated independently of the first actuator is provided. In order to release the camshaft adjuster from the late position when in an operating state, a ram of the second actuator displaces a locking pin of a late-locking device of the camshaft adjuster out of its position that locks the late position.
