Abstract: A thermal management system is disclosed configured to regulate the temperature of a number of vehicle components. The system comprises one expansion tank and two or more coolant circuits each configured to regulate the temperature of a vehicle component of the number of vehicle components. Each coolant circuit of the two or more coolant circuits comprises a heat exchanger configured to regulate the temperature of coolant in the coolant circuit, a coolant pump comprising a pump inlet, and a static line fluidly connecting the pump inlet to the expansion tank. The present disclosure further relates to a vehicle comprising a thermal management system.

Abstract: A thermal management system for a vehicle is disclosed, wherein the vehicle comprises an occupant compartment and a propulsion system configured to provide motive power to the vehicle. The system comprises a propulsion coolant circuit configured to cool at least a portion of the propulsion system, a heating circuit configured to heat the occupant compartment, and a heat pump circuit comprising a first evaporator in the propulsion coolant circuit and a condenser in the heating circuit. The propulsion coolant circuit comprises a connecting conduit connecting the propulsion coolant circuit to the heating circuit at a position upstream of the condenser, and a first valve configured to control flow of coolant through the connecting conduit. The present disclosure further relates to a powertrain for a vehicle, as well as a vehicle.

Abstract: An ultrasonic measurement device and method in which an ultrasonic transducer is acoustically coupled to an object to be measured by a resilient material contact layer. The transducer transmits a plurality of consecutive ultrasonic transmit signals into the object being measured, the transmit frequency of each of the plurality of transmit signals being distinct from the frequency of the other transmit signals of the plurality of transmit signals. Signal echoes of the transmitted signals are received, and based on the received signal echoes, at least one transmit frequency to be used for ultrasonic measurement of the object is selected.
