A vehicle heating/cooling system for a vehicle comprises an internal combustion engine coupled to a closed engine coolant circuit to recirculate engine coolant therethrough; a refrigerant compressor coupled to a closed refrigerant circuit to recirculate refrigerant therethrough, wherein the refrigerant compressor is coupled to the internal combustion engine to be driven thereby; a closed thermally regulated fluid circuit to recirculate thermally regulated fluid therethrough; and a consolidated heating/cooling core coupled to the closed engine coolant circuit, to the closed refrigerant circuit and to the closed thermally regulated fluid circuit.

A method and device for cooling and/or heating media, preferably in a motor vehicle, the method in which at least one first heat source is cooled and at least one second heat sink is heated by a thermal management system. In a method in which the heating or cooling can occur on demand, heat and/or cold are shifted by the thermal management system in space and time to the heat sink and/or heat source, which is characterized by need.

One or more environmental control systems of a vehicle are automatically operated. A position of an occupant of the vehicle in their circadian cycle is determined. The operation of one or more of the environmental control systems is controlled to compensate for or adjust the position of the occupant in their circadian cycle.

A method for operating a fragrancing device, wherein a blower device is provided which sucks air through an air inlet opening into the first air duct and conveys it to an air outlet opening. At second air duct is provided, which branches off from the first air duct at a first duct branch and rejoins the first air duct at a second duct branch. A first fragrance container is provided in the second air duct between the first duct branch and the second duct branch, which can be flowed through by the air flow in the second air duct. A first valve device is provided upstream and/or downstream and controls the flow through the first fragrance container. The blower is controlled in such a manner that a defined, substantially constant, air flow is generated as a sum through the first air duct and the second air duct.

A fragrance container of a scenting device, having a wall enclosing an interior space, wherein at least one air inlet opening and at least one air outlet opening are provided in the wall for air to flow through the fragrance container, wherein at least one carrier medium for a fragrance is arranged in the interior space of the fragrance container, wherein the at least one carrier medium has a plurality of free surfaces along which the air can flow through from the air inlet opening to the air outlet opening for the purpose of absorbing the fragrance.

The present disclosure relates to an air supply arrangement for a vehicle, the air supply arrangement comprising an air supply duct, an ionising member located in the air supply duct and a passive collecting member located in the air supply duct downstream of the ionising member, wherein a shortest path length of an air flow between the ionising member and the collecting member is in the range of from 20 to 70 centimeters (cm), preferably in the range of from 25 to 50 cm. The disclosure further relates to an external portion of such an air supply arrangement and a vehicle with such an air supply arrangement.

An information processing circuitry for controlling a content provided to a user inside a cabin of an autonomous vehicle, wherein the information processing circuitry is configured to: obtain environment data; acquire abstract content data, representing abstract content, being associated with the obtained environment data; measure initial user body data of the user and determine, based on the measured initial user body data, an initial emotional state of the user; determine and provide a first content, being associated with the abstract content, to the user; measure, in response to providing the first content to the user, first user body data of the user and determine, based on the measured first user body data, a first emotional state of the user; and if the initial emotional state and the first emotional state of the user are different: acquire user content data from a database, representing user content associated with a past user experience, being associated with the environment data, wherein the user content is associated with the first content, determine, based on a difference between the initial emotional state and the first emotional state of the user, a second content being associated with the user content and being associated with the first content, provide the second content to the user, measure, in response to providing the second content to the user, second user body data of the user and determine, based on the measured second user body data, a second emotional state of the user, and refine, based on a difference between the first emotional state and the second emotional and a difference between the initial emotional state and the second emotional state, the second content provided to the user for increasing the difference between the initial emotional state and the second emotional state of the user.

A heat exchanger for an aircraft engine includes: a body including a plate-like first member and a plate-like second member that are stacked in a thickness direction of the first and second members and joined together, and a channel which is defined in the body and in which the cooling target fluid flows; and a corrugated fin plate disposed in the channel in the body. The body is bent along a curved surface to which the heat exchanger is attached. A plurality of heat dissipation fins stand on an outer surface of at least one of the first member or the second member.

An air-treatment system for motor vehicles, for example an ionizer for installation in a motor-vehicle air conditioner, has an air-treatment device by means of which air of an airflow generated by the motor-vehicle air conditioner can be treated, and has a controller by means of which the air-treatment device can be controlled in accordance with parameters of the motor-vehicle air conditioner in which the air-treatment device is installed. In order to reduce significantly the effort for the design of such air-treatment systems and in particular for their controllers and in order to create the possibility of using a universal control device as controller, it is proposed that the air-treatment device has an electrical coding means which is characteristic of the variant of the air-treatment device, can be brought into electrical connection with the controller on installation of the air-treatment device and the controller, and can be interrogated by the controller after the electrical connection to the controller has been established.
