  • Patent number: 10677859
    Abstract: Embodiments relate to magnetoresistive sensors suitable for both angle and field strength sensing. In an embodiment, a sensor comprises two different magnetoresistive (xMR) sensor components for sensing two different aspects or characteristics of a magnetic field. In an embodiment, the first xMR sensor component is configured for magnetic field angle or rotation sensing, while the second xMR sensor component is configured for magnetic field strength sensing. In an embodiment, the second xMR sensor component is configured for magnetic field strength sensing in two dimensions. The second xMR sensor therefore can determine, in embodiment, whether the field sensed with respect to angle or rotation by the first xMR sensor component is of sufficient strength or meets a minimum magnitude threshold. If the minimum threshold is not met, an alarm or alert can be provided.

  • Patent number: 10606686
    Abstract: Fault detection devices, systems and methods are provided which implement identical processors. A first processor is configured to receive a first set of variables, execute a first firmware based on the first set of variables, and output a first result of the executed first firmware. A second processor, identical to the first processor, is configured to receive a second set of variables, execute a second firmware based on the second set of variables, and output a second result of the executed second firmware. The first firmware and the second firmware provide a same nominal function in a diverse manner for calculating the first result and the second result, respectively, such that the first result and the second result are expected to be within a predetermined margin. Thus, a fault can be detected by comparing the first and the second results.

  • Patent number: 10514410
    Abstract: Embodiments relate to systems and methods for sensor self-diagnostics using multiple signal paths. In an embodiment, the sensors are magnetic field sensors, and the systems and/or methods are configured to meet or exceed relevant safety or other industry standards, such as SIL standards. For example, a monolithic integrated circuit sensor system implemented on a single semiconductor ship can include a first sensor device having a first signal path for a first sensor signal on a semiconductor chip; and a second sensor device having a second signal path for a second sensor signal on the semiconductor chip, the second signal path distinct from the first signal path, wherein a comparison of the first signal path signal and the second signal path signal provides a sensor system self-test.

  • Publication number: 20190344735
    Abstract: An ECU may include a PCB, a processor, and a sensor interface component. The sensor interface component and the processor may be disposed on the PCB. The sensor interface component may obtain, from a sensor, a plurality of data samples corresponding to a physical parameter relating to a vehicle component, and generate estimation data based on the plurality of data samples. The estimation data may at least partially compensate for a delay, from a point in time at which a particular data sample is detected by the sensor to a point in time at which the particular data sample is obtained by the sensor interface component, to approximate a current value of the physical parameter. The sensor interface component may receive one or more commands for physical parameter information, relating to the vehicle component, and provide a portion of the estimation data based on the one or more commands.
