Abstract: A sensor device includes an output driver configured to: adjust a first time interval of the output signal between a first signal edge of a first type and a first signal edge of a second type based on a first reference value; adjust a second time interval of the output signal between the first signal edge of the second type and a second signal edge of the first type based on a second reference value; adjust a third time interval of the output signal between the second signal edge of the first type and a second signal edge of the second type based on a first data value; and adjust a fourth time interval of the output signal between the second signal edge of the second type and a third signal edge of the first type based on a second data value.

Abstract: Embodiments relate to a controller operable to transmit digital data messages to a receiver via a communication link having at least a first and a second transmission path, the controller comprising a first signal terminal the first transmission path and a second signal terminal for the second transmission path. The first signal terminal is operable to digitally transmit a first message to the receiver according to a first transmission technique and the second signal terminal is being operable to digitally transmit a second message to the receiver according to a second, different transmission technique.

Abstract: A signal interface for a receiver includes a first receiver module configured to receive a first message related to a content. The first receiver module is configured to generate a first adapted message based on the first message and a first transformation protocol. The signal interface further includes a second receiver module configured to receive a second message related to the content. The second receiver module is configured to generate a second adapted message based on the second message and a second transformation protocol. The first transformation protocol associated with the first receiver module and the second transformation protocol associated with the second receiver module are different.

Abstract: A method for determining information on an integrity of signal processing components within a signal path includes adding an alive signal to a signal at a first position within the signal path and detecting an added alive signal corresponding to the alive signal at a second position within the signal path. Further, the method includes determining the information on the integrity based on the detected signal.

Abstract: Embodiments relate to systems and methods for self-diagnostics and/or error detection using multiple signal paths in sensor and other systems. In an embodiment, a sensor system comprises at least two sensors, such as magnetic field sensors, and separate signal paths associated with each of the sensors. A first signal path can be coupled to a first sensor and a first digital signal processor (DSP), and a second signal path can be coupled to a second sensor and a second DSP. A signal from the first DSP can be compared with a signal from the second DSP, either on-chip or off, to detect faults, errors, or other information related to the operation of the sensor system. Embodiments of these systems and/or methods can be configured to meet or exceed relevant safety or other industry standards, such as safety integrity level (SIL) standards.

Abstract: A fault detection system includes a sensor configured to measure a physical quantity and generate a measurement of the physical quantity; a first processor configured to receive the measurement, execute a first firmware based on the measurement, and output a first result of the executed first firmware; a second processor configured to receive the measurement from the sensor, execute a second firmware based on the measurement, and output a second result of the executed second firmware, wherein 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; and a fault detection circuit configured to detect a fault when the first result and the second result are not within the predetermined margin.

Abstract: A sensor system with a sensor device communicatively coupled to a sensor bus to a receiver circuitry or processing component increases the data rate of sensor transmissions based on the sensor communication protocol. The sensor device can be a short pulse width modulation (PWM) code (SPC) protocol or a single edge nibble transmission (SENT) protocol. A first plurality of sensor values can be configured based on a first communication scheme and a second plurality of sensor values based on a second communication scheme of the communication protocol within a sensor transmission. An indication of modifications of the sensor communication protocol can further be provided via the transmission to sensor bus and processed accordingly by the receiver or processing circuitry of the sensor bus.
