An electrical stepper motor comprises a magnetical rotor and at least two electromagnetical driving coils for causing rotation of the rotator. A method of detecting an operating condition of the as e.g. a stall state of the electrical stepper motor comprises the steps of connecting one contact pin (P, M) of at least one of the electromagnetical driving coils via a high-impedance resistor (R1, R2) to a defined voltage source during a non-activated state of the driving coil, detecting a voltage induced at the driving coil during the non-activated state and converting the detected voltage into a digital signal, and digitally analyzing the digital signal and deriving an operating condition of the rotor by evaluation of the signal waveform including positive and negative components of the signal.

A method of calibrating a module whose operation is dependent upon a module clock signal, the method comprising: over each calibration period of a plurality of such periods, obtaining a measure of the frequency of an observed signal, the observed signal being the module clock signal or a clock signal generated based upon the module clock signal; influencing operation of the module in dependence upon the obtained measures so as to calibrate the module; and for each said calibration period, taking account of a position in time of the end of that calibration period relative to a particular feature of the observed signal and delaying the start of the following calibration period relative to a subsequent said particular feature of the observed signal in dependence upon that position.

A road building machine for road surface paving is provided. The machine comprises an automotive travelling mechanism with a steerable front axle of the undercarriage comprising at least one support wheel and two rear support wheels, a working device which is mounted in or on the machine frame and is approximately flush with said machine frame on one side, which is the so-called null side, a swivel unit having an articulation area formed by the machine frame and a swivel arm which carries the rear support wheel on the null side at its one end and is pivotably linked at its other end to the articulation area of the machine frame, with the swivel unit being arranged in the manner that it can be pivoted between an “outwardly pivoted position” in which the rear wheel which is on the null side is pivoted outwardly to an outer end position parallel to the longitudinal direction of the machine frame and an “inwardly pivoted position” in which the rear support wheel which is on the null side is inwardly pivoted to an inward end position which is parallel to the longitudinal direction of the machine frame, and a pivot gear which controls the adjustment of the swivel unit between the “outwardly pivoted position” and the “inwardly pivoted position” around a swivel axis.

A method for operating an exhaust gas probe, in particular a lambda probe, in the exhaust gas of an internal combustion engine, where at least one heating element for achieving the operating temperature in the exhaust gas probe and determination of the temperature of the exhaust gas probe is performed by measuring the internal resistance. Measurement of the internal resistance occurs by the superimposition of discrete bipolar test pulses that include a pulse and a counter pulse, and by acquisition of the Nernst voltage.
