Abstract: The invention relates to a computer-based diagnostic tester which can exchange information with the control devices installed in the motor vehicle using a diagnostic program via a diagnostic interface and via data lines. A method for improved checking of repairs is also presented with the diagnostic tester. The motor vehicle-mounted control devices have program routines for self-diagnostics of the control devices and are capable of storing identified faults in the form of fault codes in reserved memory areas. The diagnostic program which is implemented in the diagnostic tester reads the fault codes out from the reserved memory areas, interprets the fault codes and displays them on a display together with the interpretations. In order to check to what extent repairs which have been performed have been successfully concluded, status polling is carried out using the diagnostic program implemented in the diagnostic tester.

Abstract: A detection arrangement includes a counter unit which receives a first clock signal and a reference clock signal. The counter unit derives a first data word as a function of a time deviation between clock edges of the first clock signal and the reference clock signal. The detection arrangement further includes a signal processing unit to determine a phase deviation word as a function of the first data word and a second data word, the second data word based on the duration of a clock period of the reference clock signal.

Abstract: The invention relates to a method for producing a TFA image sensor in which a multi-layer arrangement comprising a photo diode matrix is arranged on an ASIC switching circuit provided with electronic circuits for operating the TFA image sensor, such as pixel electronics, peripheral electronics and system electronics, for the pixel-wise conversion of electromagnetic radiation into an intensity-dependent photocurrent, the pixels being connected to contacts of the underlying pixel electronics of the ASIC switching circuit. The method enables conventionally produced ASIC switching circuits to be used without impairing the topography of the photoactive sensor surface. The CMOS passivation layer in the photoactive region and then the upper CMOS metallization are removed and replaced by a metallic layer which is structured in the pixel raster, for the formation of back electrodes.

Abstract: A frequency-dividing circuit arrangement is disclosed that includes a divider chain having a plurality of frequency divider stages. The frequency dividers can be changed over between the division ratios 2 and 3. At least that frequency divider that is arranged on the output side of the divider chain has an additional through-switching input that makes it possible to switch through the input signal to the output of the divider stage without influencing the delay-time effects of the divider stage. The advantages of a cascaded 2/3 divider chain, such as a high cut-off frequency, a simple design and the ability to arbitrarily expand, are thus achieved without accepting a lower limit of the range of possible division values.
