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.

A high-frequency dynamic pressure transducer calibration system and method is provided. The method directs a source onto a diaphragm of a dynamic pressure transducer. An oscillating voltage at a target frequency (or range of frequencies) is generated. The oscillating voltage is coupled to an electrical connector of the dynamic pressure transducer. A deflection pattern of the diaphragm is recorded. The dynamic pressure transducer is calibrated by correlating magnitude of the deflection pattern with the oscillating voltage as a function of the target frequency (or range of frequencies).

An angle sensor generates an angle detection value based on a first and a second detection signal. A correction apparatus performs correction processing for generating a first corrected detection signal by adding a first correction value to the first detection signal and generating a second corrected detection signal by adding a second correction value to the second detection signal. When an angle to be detected varies with a period T and if no correction processing is performed, the angle detection value contains an Nth-order angle error component varying with a period of T/N. Each of the first and second detection signals contains an (N−1)th-order signal error component and an (N+1)th-order signal error component. The order of the first and second correction values is N−1 or N+1.

A method for calibrating at least one sensor by use of at least one calibration sensor, the method comprising: obtaining information indicative of a proximity time period when the at least one sensor and the at least one calibration sensor are in a predefined proximity zone of each other for a time period which is sufficient for calibration; obtaining information about a refractory time period for at least one of the at least one sensor and the at least one calibration sensor; calibrating the at least one sensor by a sensor reading of the at least one sensor and a sensor reading of the at least one calibration sensor, which sensor readings are taken when they are in the predefined proximity zone, wherein the refractory time period for the at least one of the at least one sensor and the at least one calibration sensor is considered by delaying its sensor reading such that it is ensured that the sensor readings of the at least one sensor and the at least one calibration sensor are spatially and temporally aligned for the calibration.

A system and method for wavelength detection includes one or more detection stages configured for receiving at least a portion of an optical carrier. Each stage includes a splitter for splitting the signal into two arms. A 90-degree optical hybrid and in-phase (I-channel)/quadrature (Q-channel) differential detectors generate I-channel and Q-channel differential signals based on the hybrid outputs. A gas cell or like multi-point wavelength reference path also receives the input signal and provides a set of reference absorption wavelengths converted into the electrical domain by a reference photodetector. A logic device receives sets of detection signals (including I-channel and Q-channel differential signals and the set of reference wavelengths, all corresponding to a common measurement time) and determines a wavelength of the optical carrier based on an arctangent of a ratio of the Q-channel and I-channel differential signals, mapped to the set of reference absorption wavelengths.

A method is provided for determining and monitoring gas consumption in a gas network under pressure or under vacuum. The gas network may include a sensor(s) capable of recording the state or status of a source(s), consumers, consumer areas or applications. The method includes: a start-up phase, during which the aforementioned sensors are calibrated before use; an optional leak quantification phase, in which unrecorded consumers or leaks are quantified on the basis of measurements from the aforementioned sensors; an operational phase, in which the flow and/or gas volume consumed by each consumer, consumer areas, application or possibly the leak/non-registered consumer is calculated or determined using a cumulative algorithm and a predefined, adjustable time horizon; an output phase, in which the calculated or determined flow and/or gas volume consumed by each consumer, consumer area, application or possibly the leak/non-registered consumer is displayed.

Various examples are directed to methods and system of managing a sensor. A measurement system may receive from the host device, a first register map describing a first configuration of the measurement system for the first sensor. The first configuration may indicate a first measurement frequency for the first sensor. The measurement system may configure a switch matrix to provide a first excitation signal to the first sensor.

The measurement system may sample a first raw sensor signal from the first sensor with the ADC at a first measurement frequency described by the first configuration. The measurement system may generate first digital measurement data based at least in part on the first raw sensor signal and send the first digital measurement data to the host device.

A method for calibrating a sensor of a vehicle is provided. In this method, a sensor measured value that includes a measuring position and a measurement time is received by a data processing unit. Based on the measuring position and the measurement time, the sensor measured value is assigned to at least one reference measured value, which has been ascertained with a reference sensor of a reference vehicle at a reference position and at a reference measurement time, if the measurement time of the sensor measured value and the reference measurement time deviate from one another by a maximum of 30 minutes. In addition, at least one reference calibration value of the reference sensor is communicated to the vehicle and/or provided to the vehicle, so that an instantaneous calibration value of the sensor may be adapted based on the reference calibration value.
