A measuring apparatus for detecting a relative movement between at least one magnetic field sensor array integrated into a semiconductor chip and a transmitter for the sensor array is provided. The transmitter and the sensor array are exposed to the magnetic flux of a magnet. The transmitter has teeth that can be moved past the sensor array during the relative movement, or the transmitter has magnet poles that can be moved past the sensor array during the relative movement. The magnetic field sensor includes a differential magnetic field sensor which comprises a first measuring plate and a second measuring plate that are offset in relation to one another in a direction of the relative movement. The magnetic field sensor also includes a sensor element which is designed to measure the absolute magnetic field and comprises a third measuring plate that is arranged between the first measuring plate and the second measuring plate in the direction of the relative movement.

The invention relates to a circuit configuration with a serial test interface (TIF) to control a test operation mode, a freely programmable digital processor (CPU), a housing (G) for the accommodation of a test interface (TIF) and the processor (CPU) with terminals or connectors (C0, C1) for data and/or signal exchange with external components and setups. At one of the terminals (C1), a modulated supply voltage (VDD) can be received the transfer of data (d) and or a clock (T) by using at least two voltage levels (V2, V3) that can be controlled and which are different from a supply voltage level (V1) that is designed to feed the circuitry with a supply operating voltage. Furthermore, the invention relates to a serial test operation method for such a circuit configuration.
摘要:
In a method for monitoring the function of a sensor module, which has a sensor, by means of the sensor a measurement signal for a physical quantity to be determined is generated and applied to an output terminal in an unchanged form or in processed form—after at least one linear signal processing step and/or at least one nonlinear signal processing step are performed. In addition, a test signal is generated whose spectrum lies substantially outside the spectrum of the measurement signal. The test signal is supplied at a place in the sensor from which it reaches the output terminal in unchanged form or in processed form—after the performance of the at least one linear signal processing step—only in the case of a functional sensor. An output signal present at the output terminal is compared with the test signal and a diagnosis signal is generated, which indicates whether the test signal is present at the output terminal. The test signal is filtered out of the output signal and the remaining signal is applied as the measurement signal at a measurement signal output of the sensor module.
摘要:
An error correction and/or error detection method reads of stored information data from a storage device; wherein in addition to the information data, code data is read from the storage device. Syndrome data is formed from the information data and the code data in order to determine errors and/or error positions in the read data. For detection of multiple errors, it is verified whether in the case of a determined error position, the information data or code data associated with the relevant storage positions are either all equal to 0, or are all equal to 1.
