    Abstract: A device for generating a sensor signal suitable for an in-operation test of a signal path from a sensor cell to an evaluation location. The sensor cell provides a sensor cell output signal depending on a physical magnitude to be detected which is changed in means for changing the sensor cell output signal according to a predetermined change regulation based on a test signal in order to obtain the sensor signal. A signal derived from the sensor signal is detected by a device for an in-operation test of the signal path and is evaluated.

    Abstract: The present disclosure is directed towards a sensor interface module that delivers a supply voltage to a plurality of sensors, and which exchanges data signals between the plurality of sensors and a control unit (e.g., an ECU). The sensor interface often employs a single-bit comparator (or a coarse analog to digital converter (ADC), e.g., a 2-bit or 3-bit ADC) to track signals to be exchanged between the sensors and controller over the sensor interface. Compared to power hungry ADC with more bits (e.g., 32 bit ADC), the single-bit comparator/coarse ADC limits hardware complexity and power consumption. In addition, in some embodiments the sensor interface module can include an estimator and assist comparators to speed up the tracking ability of the sensor interface module. In this way, techniques provided herein facilitate reliable, low-power communication between a control unit (e.g., an ECU) and its corresponding sensors.

    Abstract: The disclosed invention provides a structure and method for easily measuring capacitive and/or resistive components of a sensor system. In one embodiment, the structure comprises a signal generator configured to output a load current to a measurement element containing measurement sensor elements and a parasitic capacitance. A controllable excitation voltage is generated, via integration of the load current on the parasitic capacitance, and output to the measurement sensor elements having capacitive and resistive components. The controlled voltage through the measurement device may be manipulated to cause the capacitive and resistive components to exhibit a transient effect. The resulting output current, provided from the measurement device therefore has transient response characteristics (e.g., the settling time, amplitude) that can be selectively measured by a measurement circuit to easily determine values of the capacitive and resistive measurement elements. Furthermore, dedicated demodulation techniques may be used to measure the capacitive and resistive components.

    Abstract: A receiver for receiving messages from a transmitter includes a controller and a driver stage for providing a supply voltage to the transmitter based on a control signal. The controller is configured to provide the control signal to compensate for changes of the supply voltage caused by a modulation of the current consumption of the transmitter, such that the supply voltage remains in a predefined range. Furthermore, the controller is configured to evaluate a series of succeeding values of the control signal to derive a message generated by the transmitter by modulating its current consumption.
