Abstract: A method is provided for controlling the alignment of a heliostat with respect to a receiver, wherein an image sensor device is arranged on a mirror device of the heliostat, wherein the heliostat is aligned by the image sensor device using image recognition in such a way that a first angle of a first vector pointing towards the sun, relative to a prescribed vector of the mirror device, and a second angle of a second vector pointing towards a prescribed target area of the receiver, relative to the prescribed vector, are in a relationship to each other which is dependent upon the prescribed vector of the mirror device, and wherein images of the sun and the prescribed target area and their position relative to the prescribed vector are determined.

Abstract: A method and a device for automatic detection of an equipment status of optional power consuming components, such as an air conditioning compressor, for an automobile are described. A signal formed in the automotive controller is monitored as a function of an engine load to determine whether the signal undergoes a certain change, for example, reaches a predetermined range, when an optional power consuming component is turned on, or power is demanded through corresponding switch operation, indicating the presence of the optional power consuming component, with the goal of achieving a permanent change in control data as a function of the automotive equipment present.

Abstract: In order to provide an insulation system for internal thermal insulation of a pressure chamber which can be subjected to pressure by a gas flow, the system being constructed for arrangement at an inner surface of an outer jacket of the pressure chamber and comprising at least one layer of insulating material, whereby good thermal insulation can be obtained with little maintenance work, it is proposed that the insulation system should comprise means for equalizing pressure between the insulating material and an internal chamber, which means are arranged over a large area relative to a surface of a layer of insulating material.

Abstract: An improved pressure vessel which has a fluid flowing through it can be simply manufactured and has a high operational safety. The fluid may be heated by radiation, such as solar radiation. A guiding device with inlet and outlet stream guides is arranged in the interior of the pressure vessel to guide a stream of the fluid. The inlet stream guide and the outlet stream guide are separate from one another, and are formed in the vessel interior by the guiding device. The stream of fluid is guided from the inlet stream guide to the outlet stream guide. Additionally, a branch stream of the stream of fluid is returned from the outlet stream guide to the inlet stream guide via a passage of the guiding device due to a lower pressure that is created in the inlet stream guide.

Abstract: To provide a process for the manufacture of a ceramic part which is a ceramic part resistant to temperature changes and, in particular, suitable also for high temperatures, it is suggested that a formed body be produced by forming and sintering a ceramic material essentially comprising non-oxidic ceramic components and that the ceramic part be produced from the formed body by oxidizing the ceramic material starting from a surface of the formed body.
