    Abstract: Magnetic sensor modules, systems and methods are provided, configured to detect a rotation speed of an object. A magnetic sensor module includes a plurality of sensor elements configured to generate measurement values in response to sensing a magnetic field, the plurality of sensor elements being grouped into three pairs; and a sensor circuit configured to generate a first shifted differential measurement signal based on the measurement values received from a first shifted pair of sensor elements, a central differential measurement signal based on the measurement values received from a central pair of sensor elements, and a second shifted differential measurement signal based on the measurement values received from a second shifted pair of sensor elements, and generate an output signal based on detecting the first shifted differential measurement signal, the central differential measurement signal, and the second shifted differential measurement signal crossing at least one threshold.

    Abstract: A crash sensor device may include multiple sensor components positioned along one or more data paths to a communication interface of the crash sensor device. The crash sensor device may include a test control unit. The test control unit may receive a test command from an electronic control unit during operation of a vehicle. The test control unit may perform a test of one or more sensor components, of the multiple sensor components, during operation of the vehicle based on the test command. The test control unit may output a test result to the electronic control unit based on performing the test.

    Abstract: A gas sensor includes a transmitter that may transmit a first radar signal, associated with a resonance peak corresponding to a first gas, through a space including the first gas and a second gas. The first gas may absorb a portion of the first radar signal to create a second radar signal. The transmitter may transmit a first infrared (IR) signal, associated with a second resonance peak corresponding to the second gas, through the space. The first gas or the second gas may absorb a portion of the first IR signal to create a second IR signal. The gas sensor may include a controller to determine a concentration of the second gas based on the second radar signal and the second IR signal.

    Abstract: A receiver includes a receiver circuit to receive a pulse width encoded signal and a sampling circuit to determine a position of a transition of the pulse of the signal by oversampling the received signal with respect to a quantization function and to generate a signal indicating an unexpected event, when the determined position of the transition deviates from an expected position according to the quantization function by more than a predetermined range, wherein the quantization function maps a plurality of expected positions to a plurality of values.

    Abstract: An inductive sensor may include a first angle measurement path associated with determining an angular position based on a first set of input signals. The inductive sensor may include a second angle measurement path associated with determining an angular position based on a second set of input signals. The inductive sensor may include an amplitude regulation path associated with regulating amplitudes of a set of output signals. The inductive sensor may include a safety path associated with performing one or more safety checks. Each safety check of the one or more safety checks may be associated with at least one of the first angle measurement path, the second angle measurement path, or the amplitude regulation path.

    Abstract: A monitoring system includes: a sensor configured to generate a sensor signal based on a measured property; a controller configured to communicate with the sensor; and a communication channel electrically coupled to the sensor and the controller for carrying electrical communications therebetween. The sensor includes a transmitter configured to transmit an electrical signal on the communication channel to the controller. The controller includes a processing circuit configured to receive the electrical signal, measure an actual signal function response of the electrical signal, correlate the actual signal function response with a reference signal function response to generate a correlation value, compare the correlation value and a correlation threshold to produce a comparison result, and detect a fault based on the comparison result indicating that the correlation value satisfies the correlation threshold.
