Abstract: A radar target simulator with no lower target distance limitation and continuous distance emulation is provided. Said radar target simulator comprises a receiving unit configured to receive a radar signal from a radar under test and to provide a corresponding receive signal, and a ramp slope estimating unit. In this context, the ramp slope estimating unit is configured to track the ramp slope of the radar under test on the basis of the receive signal.

Abstract: For underlining a text section a command is typed both before and after the text section in the typing sequence, which command causes the storing of position values in two registers. The underlining is then performed underneath the already entered characters. A command for line advance, facultatively in connection with returning the printing head to a left position, ensures that the underlining will be performed prior to the line advance, but that the conditions for the underline will be retained also for the next line.

Abstract: Method for resetting the print head of a typewriter or similar machine to a starting position. In a processor-controlled typewriter or similar machine, the steps of a vertical repositioning of the recording medium are added and stored. If the added value indicates an upward movement of the recording medium, this value is cancelled as a character is printed. If, contrarily, a downward movement of the recording medium is indicated, the value is retained. Moreover, the current horizontal position of the printing head and, when it is repositioned horizontally, also the position of the last printed character, are stored. Upon initiation of an automatic reset function of the printing head to the end of the printed text, after a repositioning in horizontal and/or vertical direction, for instance for purposes of a correction, the stored information is evaluated for activation of the printing head drive and the recording medium drive.
