Abstract: A sensor controller for a sensor module includes at least one interface to obtain sensor information from the sensor module and to communicate with a sensor signal receiver. The sensor controller includes a control module to control the at least one interface. The control module is configured to obtain the sensor information from the sensor module; generate a sensor signal based on the sensor information; and transmit the sensor signal. The control module is further configured to detect a fault state of the sensor module; transmit a fault indicator if the fault state indicates a failure of at least a part of the sensor module; and receive a control signal from the sensor signal receiver based on the fault indicator. The control signal includes at least one fault handling instruction. The control module is configured to execute the at least one fault handling instruction.

Abstract: A sensor device includes an implantable sensor unit, a transponder unit, and a wired connection flexibly and electrically connecting the implantable sensor unit and the transponder unit. The implantable sensor unit is adapted to be implanted into a body. The implantable sensor unit includes a comparator and a sensor adapted to sense a characteristic of the body in vivo. The sensor is adapted to supply an analog signal to a first input of the comparator. The transponder unit is adapted to supply a control signal to the implantable sensor unit and to receive an output signal of the comparator. The implantable sensor unit is adapted to supply an analog approximation signal to a second input of the comparator in response to the control signal. The wired connection is adapted to transmit the control signal and the output signal of the comparator.

Abstract: A device may obtain raw sensor data, collected by a sensing device, including a set of signal values and a set of temperature values corresponding to the set of signal values. The set of signal values may correspond to a magnetic field present at the sensing device. The device may determine, based on the set of signal values, a first value of a calibration parameter associated with calibrating the sensing device. The device may associate, based on the set of temperature values, a particular temperature value with the first value of the calibration parameter. The device may determine, based on the particular temperature value and a temperature compensation function associated with the calibration parameter, a second value of the calibration parameter. The device may selectively update the temperature compensation function based on a comparison of the first value and the second value.

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.

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: 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.
