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 magnetic angle sensor device and a method for operating such device is provided. The magnetic angle sensor device includes a shaft rotatable around a rotation axis; a magnetic arrangement coupled to the shaft, where the magnetic arrangement produces a differential magnetic field comprising a plurality of diametric magnetic fields; a first magnetic angle sensor provided in the differential magnetic field and configured to generate a first signal that represents a first angle based on a first diametric magnetic field of the differential magnetic field; a second magnetic angle sensor provided in the differential magnetic field and configured to generate a second signal that represents a second angle based on a second diametric magnetic field of the differential magnetic field; and a combining circuit configured to determine a combined rotation angle based on the first signal and on the second signal.

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 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.

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: Integrated circuit systems, such as sensor systems, having on-board-diagnostic (OBD) circuits for the detection of errors presenting internal to the systems are disclosed, along with related methods. In one embodiment, an ADC multiplexer receives analog output readback from an output driver and provides a signal triggering an OBD circuit for internal error indication performed completely independent of digital-to-analog converters (DAC) and output drivers, which can be the point of failure.

Abstract: A sensor interface operates to communicate a sensed quantity along one or more processing pathways and in different data representations. The signal representations can be swapped along one or more locations of the signal processing branches. These branches are independent from one another and combined at an interface component for transmission along a single path or node for a control unit.
Abstract translation: 传感器接口用于沿着一个或多个处理路径和不同的数据表示传达感测量。 信号表示可以沿着信号处理分支的一个或多个位置进行交换。 这些分支彼此独立，并且在接口部件处组合以沿着用于控制单元的单个路径或节点进行传输。
