Abstract: An interfacial sensor and method for determining the thickness of an interface above a surface of a body around which flow occurs. The sensor has a first device for determining a first temperature, a second device for determining a second temperature and a third device for determining a third temperature. Each device is arranged at a predefinable distance (XI, X2, X3) from the surface of the body) around which flow occurs. At least the second device for determining the second temperature and the third device for determining the third temperature includes at least one wire which extends from the surface into a half-space adjoining the surface and which has a diameter of approximately 300 ?m or less. Such a sensor may find use in a wind turbine, a vehicle, an aircraft, a room climate measuring device or a ship.

Abstract: A device and method for increasing comfort in an aircraft. The device and method utilizes a surface arranged between a ceiling paneling of a cabin of the aircraft and a passenger. The surface is arranged to face the passenger and is positionable so that a distance between the surface and the passenger is changeable. The device is structured and arranged to at least one of affect a thermal comfort of the passenger and supply air to the passenger via the surface.

Abstract: What is described here is a method of air conditioning in vehicles and in aircraft in particular, wherein the air flow supplied to the passenger cabin consists of outside air possibly heated to a moderate temperature and a fraction of circulated air. The inventive method is characterised by the provision that the fraction of circulated air in the supplied air flow is limited by means of at least one CO2 sensor in such a way that the CO2 fraction in the air in the passenger cabin does not exceed a defined threshold. Alternatively or additionally it is possible, below the threshold of circulated air as pre-determined by the CO2 sensor, to control the circulated-air fraction in the supplied air flow in such a way that the relative humidity is maintained within a humidity range which is higher than the relative humidity after heating to room temperature, and that the supplied air flow is introduced into the passenger cabin via at least one filter.

Abstract: A system for ventilating the interior of a vehicle by introducing processed outside air (added air) via the roof of the vehicle via outlet openings in the roof of the vehicle which are individually allocated and generally congruent to seat surfaces and through which the added air issues directed in a vertical direction at the respective seat surface and wherein outlet openings are provided under the vehicle seats for expelling air from the vehicle interior.
