Abstract: This document describes techniques, apparatuses, and systems for radar interference mitigation using signal pattern matching. Radar signals (e.g., chirps) received by a radar system may include interference from other nearby radar systems. The interference can result in reduced sensitivity of the radar system. The techniques, apparatuses, and systems described herein mitigate the interference by selecting an uncorrupted segment of the radar signal that neighbors a corrupted segment, analyzing the radar signal to identify a match segment that has similar signal characteristics to the neighbor segment, and replacing the corrupted segment with a segment that is adjacent to the match segment. In this manner, a noise floor of the radar system may be lowered, leading to increased sensitivity.

Abstract: The valve module can be installed regardless of an oil level, for example of an oil level of an oil sump of a motor vehicle. By means of a buffer volume having an overflow it is always guaranteed that a leakage flow conveyed past a valve piston includes no air but consists solely of hydraulic medium, since the overflow guarantees a level of hydraulic medium which lies above an upper face of the valve piston in a preferred installation position. As a result, foaming of the hydraulic medium can be prevented. The valve module can also be installed above the oil sump, for example in an upper region of a gearbox of the motor vehicle. In addition, the oil from the overflow can be used for cooling/lubrication of further drive train components.
