Abstract: A sensor system and an alerting unit. The sensor system according to the invention may comprise first sensing element configured to measure a first signal indicative of a velocity of a movement of an object and a second sensing element configured to measure a second signal indicative of a direction of the movement, further comprising an alerting unit configured to issue a warning if a predefined relationship between the first signal and the second signal is being violated. The invention further teaches an alerting unit configured to monitor a predefined relationship between a first signal and a second signal and further configured to issue a warning should the predefined relationship become violated.

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.

Abstract: A monitoring device of a sensor may obtain a first signal at a point on a first branch of a signal path of the sensor. The monitoring device may obtain a second signal at a point on a second branch of the signal path of the sensor and may monitor the first signal for first characteristics indicated by the first signal. The monitoring device may monitor the second signal for second characteristics indicated by the second signal. The monitoring device may determine whether a quantity of first characteristics indicated by the first signal without a particular quantity of second characteristics being indicated by the second signal reaches a threshold quantity of first characteristics. The monitoring device may assess functionality of the signal path based on whether the quantity of first characteristics indicated by the first signal without a particular quantity of second characteristics being indicated by the second signal reaches the threshold quantity of first characteristics.
