Abstract: A data transmission system includes at least one transmission line. A sender is configured to send data frames to the at least one transmission line and a recipient is configured to receive the data frames from the at least one transmission line. The sender and the recipient are both configured to determine a check sum based on a plurality of corresponding data frames that are sent to and, respectively, received from the at least one transmission line. A check sum comparing unit is configured to receive and to compare the check sum determined by the sender and the corresponding check sum determined by the recipient. The check sum comparing unit is also configured to signal a transmission error or initiate a safety function when the check sums compared are not equal.

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.
