Abstract: The present invention relates to a measured value transducer (3) having an internal data memory (32), a processing apparatus (2) for such a measured value transducer (3), and a method for storing data in an internal data memory (32) of such a measured value transducer (3). The internal data memory (32) comprises a plurality of memory areas. A respective count value, which corresponds to a frequency of an occurrence of measured values in a certain measured value range, is respectively stored in at least two memory areas of the plurality of memory areas. Thereby, data relating to a loading of a measured value transducer can be stored directly in it and can later be directly and unambiguously allocated to it. Thereby a tamper-proof storage of the data is possible, and a producer or seller of the measured value transducer can determine whether it has been overloaded, in case that e.g. a complaint is made by an end user.

Abstract: A projection method and projection device for projecting an overall image to interior walls of an aircraft, in which method or device the boundary regions of several partial images of an overall image to be presented are matched correspondingly, and partial images are pre-distorted in order to, in this way, obtain a large-area non-distorted image presentation even in the case of complex geometric shapes of projection areas, in which image presentation the transition regions of partial images are at least perceptible only to a limited extent.
