Abstract: A flow body for an aircraft includes a recess in a surface of the flow body, a first structural component with a porous material and may also include a second structural component with a porous material. The recess includes a front recess region and a rear recess region. The first structural component is arranged in, or on, the front recess region and the second structural component may be arranged in, or on, the rear recess region. An aircraft having the flow body, a weapons system having the flow body and a method for manufacturing a flow body for a vehicle are also described.

Abstract: A method for acquiring image data of a body part of a patient by means of a ultrasonography device comprising the following steps: providing a transducer of the ultrasonography device, said transducer comprising a first orientation sensor; attaching a second orientation sensor to the skin of the patient above the body part; detecting the orientation of the first orientation sensor relative to the second orientation sensor and verifying, whether the relative orientation corresponds to a target value; and acquiring image data of the body part, once the relative orientation corresponds to the target value.

Abstract: A system with an internal combustion engine which has a heat transfer circuit, a fuel cell and a climate control unit which is accommodated in the heat transfer circuit of the internal combustion engine. The system has a heat transfer arrangement for transferring the exhaust heat of the fuel cell to the heat transfer circuit and a bypass for bridging a segment of the heat transfer circuit which runs through the internal combustion engine so that, in the bypassed operating state, an isolated circuit is formed. In stationary operation, this enables an optimized operating mode since the internal combustion engine is no longer heated and the exhaust heat of the fuel cell is fully available for heating purposes.
