A system for checking a program memory) of a processing unit includes a check module, and the processing unit is made up of an instruction counter connected to the check module. The check module has a register connected to a first changeover switch that sets the register content. In a system that allows for the instruction addresses of the entire program memory to be checked, the instruction counter contains an ancillary counter, which runs through the instruction address space of the program memory independently of the program code during normal operation and which is connected to the register.

The invention relates to a method for unambiguously determining a physical parameter Φ using m phase-measured values αi with 1≦i≦m, whereby the phase-measured values αi have different, integer periodicity values ni and an integer periodicity difference (a) with Δn>1 within an unambiguous range E of the physical parameter Φ. A value T with (b) and (c) is calculated based on the phase-measured values αi and the periodicity values ni thereof, and, within a reduced unambiguous range Ered with (d), a value V is allocated to the value T by allocation according to (e), wherein TUk stands for a respective lower limit and TOk for a respective upper limit of T. The allocation intervals between the upper (TOk) and the lower limits (TUk) for T, as wells as the distances (f) correspond at least to the periodicity difference Δn. In order to determine the physical parameter Φ, value V is added up with the C phase-measured values αi in a weighted manner.

An ultrasonic flow sensor, in particular for determining the flow velocity of a medium flowing through a pipeline, has at least one ultrasonic converter for transmitting and/or receiving ultrasonic signals, an oscillator, which is connected with the ultrasonic converter, and an evaluation unit, which determines a phase shift of the ultrasonic signal that was received, with respect to a reference signal. The evaluation unit includes a plurality of quadrature demodulators, which operate with different demodulation frequencies and each determine phase information about the ultrasonic signal that was received, and when a vernier unit is provided, which determines—based on the individual pieces of phase information—a phase angle or a quantity proportional thereto.
摘要:
The present invention relates to a method and a circuit arrangement for evaluating phase signals for determining an angle or a path of a linearly or rotationally displaced component, whereby a number (N) of measured phase values (α), produced by scanning at least one phase sensor arrangement on the linearly or rotatably displaced component by means of an assigned sensor, are evaluated. According to the invention, once the measured phase values (α) have been transformed with a matrix (M1), a quality level (R) is determined by producing a vector (T) followed by the result of a quantization operation (V) regarding the vector (T). Once a transformation has been carried out with a further matrix (M4), a further vector (X) is produced from the difference (t) between the vector (T) and the result of the quantization operation (V), coefficients (Cj) and (Dj) being applied to the components (xj) of said other vector, and the quality level (R) is derived therefrom.
