Abstract: An exhaust liquid treatment assembly for a fuel cell system (FCS). The FCS includes a fuel cell stack and an FCS exhaust pipe fluidly connected to the fuel cell stack and configured to expel an exhaust stream from the FCS. The exhaust liquid treatment assembly includes a liquid tank having a liquid inlet in fluid communication with the FCS exhaust pipe and a liquid outlet. A liquid treatment filter separates the liquid inlet from the liquid outlet and includes a pH controlling material configured to mix with a liquid passing through the liquid treatment filter. A liquid level sensor configured to determine a level of liquid in the liquid tank. A controller is in communication with the liquid level sensor and configured to regulate a level of the liquid within the liquid tank by selectively opening and closing an outlet valve in fluid communication with the liquid outlet.

Abstract: A system for detecting sensor position change (DCPC) on movable vehicle components includes two or more sensors on at least one of the movable vehicle components. The sensors detect optical information within a distinct field of view (FOV) about an environment surrounding the vehicle. The distinct FOV of each sensor at least partially overlaps with an FOV of at least one other sensor. The system includes controllers that execute an application for DCPC. The DCPC application acquires overlapping optical information from the sensors, computes a conditional correspondence probability distribution for feature points in the overlapping optical information, computes a normalized joint entropy of the feature points, determines that the sensor is in a position manageable by the DCPC, continuously monitors positions of each of the sensors, selectively dynamically aligns the sensors, and ensures that the sensors are calibrated for vehicle perception tasks including advanced driver assistance system (ADAS) functions.

Abstract: A vehicle system includes a user device configured to produce acoustic sounds at varying frequencies. The vehicle system also includes a vehicle microphone for collecting acoustic data from the user device. Additionally, the vehicle system includes a vehicle processor for storing vehicle data including the acoustic data and a server communicatively coupled to the vehicle processor. In some examples, the server is configured to determine if the acoustic data match one or more predetermined frequencies of sound.
