Abstract: A magnetic sensor may determine information, associated with a magnet wheel, that is associated with a rotational speed of the magnet wheel or a rotational direction of the magnet wheel. The magnetic sensor may determine information, associated with the magnetic sensor, that is associated with a property of the magnetic sensor. The magnetic sensor may provide a signal including the information associated with the magnet wheel and the information associated with the magnetic sensor. The signal may be provided using a pulse width modulation technique associated with at least three signal levels and at least two signal thresholds. A period of time during which the information associated with the magnetic sensor is provided may at least partially overlap a period of time during which the information associated with the magnet wheel is provided, or may be provided without a time offset from the information associated with the magnet wheel.

Abstract: A signal generator comprises a signal provider and a signal processing unit. The signal provider is configured to provide a sensor signal indicating a repeatedly detected event, occurring within differing time intervals. The signal processing unit is configured to generate a transmit signal based on the sensor signal. The transmit signal comprises event information representing the temporal occurrence of the event and additional information representing additional data. The event information comprises pulses associated to detected events, wherein the pulses are temporarily separated within the transmit signal according to the differing time intervals of detected events so that each time interval of the differing time intervals comprises one pulse associated to a detected event. Further, the additional data comprises at least one frame comprising a predefined number of additional data bits. The information of the additional data bits of the at least one frame is distributed over at least two time intervals of the differing time intervals.

Abstract: A sensor device includes a two-pin current interface including an input pin configured to draw an input current and an output pin configured to output an output current, a sensor configured to generate a measurement signal, and a current modulator configured to generate a current pulse as the output current such that the output current toggles between at least two main current states based on the measurement signal. The current modulator is configured to modulate the output current such that the output current is increased, to a first current level greater than the at least two main current states, at an initial phase of the current pulse for a first duration, and to modulate the output current such that the output current is decreased, to a second level less than the at least two main current states, at a terminal phase of the current pulse for a second duration.
