    Abstract: Embodiments of the present disclosure include methods, apparatuses, systems, and computer program product for enabling multi-point shunt calibration of a sensor device. Multi-point shunt calibration provides at least a first, second, and third simulated calibration output, each simulated calibration output corresponding to an actual reading value and an expected reading value. The simulated calibration outputs are associated with a predefined output sequence, where each simulated calibration output is separated from an adjacent simulated calibration output by an output step size. Some embodiments are configured for automatically outputting each simulated calibration output for a particular period of time before outputting an adjacent simulated calibration output in the predefined output sequence. The various simulated calibration outputs, actual reading values, and/or expected values may be used in determining calibrated reading values for the sensor device.

    Abstract: The disclosure includes embodiments for improving quality of service for a vehicular plug-and-play ecosystem. A method according to some embodiments includes receiving environment data describing an environmental condition of a vehicle sensor. The method includes determining a quality of service value for the vehicle sensor based on the environment data. The method includes determining a corrected sensor measurement for the vehicle sensor based on the quality of service value. In some embodiments, the vehicle sensor includes a non-transitory memory that stores digital data that describes the environmental condition and the quality of service value for the vehicle sensor when it operates in the environmental condition. In some embodiments, the quality of service value is a factor that corrects the sensor measurement of the vehicle sensor when it operates in the environmental condition.

    Abstract: A method corrects errors in position-measuring devices having material measures which are scanned by at least one scanning unit. Correction values are obtained in a calibration performed prior to a measurement operation. The correction values from the calibration are compressed for the measurement operation. The correction values are kept available for a defined number of correction points on the material measure and used during the measurement operation to correct acquired position values.

    Abstract: According to a method and apparatus disclosed herein, an electronic register advantageously logs raw sensor data without converting the raw sensor data into physical-domain measurements, and without need for being configured to understand or process such data, or account or compensate for any sensor installation particulars. Instead, the electronic register advantageously stores conversion data in association with each sensor interface circuit being used to collect raw sensor data from a corresponding external sensor, and it provides the conversion data to an external device, in association with read-out of the raw sensor data logged by the electronic unit. The conversion data provides the mathematical expression, along with any compensation or adjustment values needed, to convert the raw sensor data into corresponding physical-domain measurements.

    Abstract: A highly integrated programmable sensor interface with improved sensor signal calibration and conditioning functions is described. The programmable sensor interface according to the present invention sensor interface provides programmable gain, digital offset correction and bias for one or more signal channels on one chip on a per channel basis. According to another aspect of the invention, the sensor interface provides reference voltage and sensor biasing by using an on-chip precision voltage regulator. According to one aspect of the invention, multiple inputs are multiplexed and each is applied to a variable gain instrumentation amplifier, which connects to the output. The offset of a given channel is controlled by an on-chip DAC which has multiple digital storage registers, allowing each channel to have a unique, stored offset. Offsets and gains are programmed externally.

    Abstract: A sensor for an encoder. The sensor includes a sensing circuit, an active setting module, an inactive setting module, and a sensor interface. The sensing circuit module is configured to generate an output signal related to a sensed characteristic. The active setting module includes a first pole width setting. The first pole width setting is associated with a first pole width for the encoder. The first pole width setting is accessible by the sensing circuit module. The inactive setting module includes second pole width setting. The second pole width setting is associated with a second pole width for the encoder. The second pole width setting is not accessible by the sensing circuit module. The sensor interface is configured for retrieving the second pole width setting from the inactive setting module and writing the second pole width setting to the active setting module.
