Abstract: A Schiefspiegler telescope with three reflecting surfaces, preferably for observing the earth from space, particularly for imaging radiometers. A novel possibility for realizing a reflector telescope without vignetting which permits a simple construction and a simple adjustment of the reflecting surfaces relative to one another. In a Schiefspiegler telescope with three reflecting surfaces whose mirror axes are arranged within a plane, the primary reflecting surface and tertiary reflecting surface are convex surfaces of identical shape arranged symmetrically with respect to an axis of symmetry. The secondary reflecting surface is arranged symmetric to the primary reflecting surface and tertiary reflecting surface so as to be rotationally symmetric around the axis of symmetry so that all three reflecting surfaces have an axially symmetric mirror arrangement with respect to design in which the optical imaging is transmitted to a receiver in the manner of an off-axis telescope.

Abstract: The invention describes an analyzing device for an embedded system (9), which has at least one CPU (1), at least one CPU bus (2), and at least one memory (3). The device includes a communication module (4) for the input or output of analysis data using a test interface (5), which, in addition to control lines, includes at least one group of data lines. The data words and the address words are transmitted alternately or in other succession by way of the test interface. This achieves the advantage of error detection while using few basic cycles of the CPU.

Abstract: The invention is directed to a Schiefspiegler telescope with three reflecting surfaces, preferably for observing the earth from space, particularly for imaging radiometers. It is the object of the invention to find a novel possibility for realizing a reflector telescope without vignetting which permits a simple construction and a simple adjustment of the reflecting surfaces relative to one another.

Abstract: Disclosed is a system and method for the detection and/or correction of memory access errors in computer systems. Test data (P) is generated in addition to data (D) which is to be secured, using the latter data (D), and is stored inside a memory (4) in such a fashion that a particularly high rate of reliability in error detection and correction can be achieved. To this end, in addition to the data (D) to be secured, the data's addresses are taken into account according to the present system and method when generating the test data (P).

Abstract: The invention discloses an analysis device for an embedded system (9) comprising a CPU (1), a CPU bus (2) and a memory (3). The embedded system has at least one communication module (4) for the input or output of analysis data by way of a test interface (5). The communication module permits the internal memory and the input and output access operations of the embedded system to be monitored and/or logged without using the clock cycles of the CPU (1).
