This disclosure is directed to methods, computer program products, and systems for calibrating one or more remote sensing devices in an environment. The disclosed technology relates to a calibration device configured to determine measurement data within an environment. The calibration device may transmit the measurement values, or other calibration data items, to a remote sensing device via a wireless link while the remote sensing device stays with a structure in which the remote sensing device is commissioned to operate. In response to receiving the calibration data items, the remote sensing device may adjust one or more settings of the remote sensing device in order to satisfy a calibration threshold.

Methods and apparatuses are provided, in which a magnetic field is measured using a coil in a first operating mode and a magnetic field is generated using the coil in a second operating mode in order to test a further magnetic field sensor.

A MEMS system includes a gyroscope that generates a quadrature signal and an angular velocity signal. The MEMS system further includes an accelerometer that generates a linear acceleration signal. The quadrature signal and the linear acceleration signal are received by a processing circuitry that modifies the linear acceleration signal based on the quadrature signal to determine linear acceleration.

An apparatus for calibration of a bio-information estimation model includes a sensor configured to obtain a bio-signal from an object in a reference interval; a feature extractor, implemented by at least one processor, configure to extract a reference feature value from the bio-signal; and a calibrator, implemented by the at least one processor, configured to determine whether a condition is satisfied based on at least one of the reference feature value and an offset value, and based on determining that the condition is satisfied, configured to calibrate the bio-information estimation model based on the reference feature value and the offset value.

There is provided an optical encoder with alignable relative positions between elements including an encoding medium, a sensor package and a memory. The sensor package includes a photodiode array and two alignment photodiodes opposite to the encoding medium. The memory records an alignment pattern associated with output signals of the two alignment photodiodes when the encoding medium and the sensor package are at nominal operating positions. When the encoding medium and the sensor package are not at the nominal operating positions, the relative position alignment is performed by adjusting current relative positions between the encoding medium and the sensor package to cause a current pattern associated with output signals of the two alignment photodiodes to be identical to the alignment pattern.

To effectively utilize work information acquired by maintenance of an instrument in a plant, an apparatus is provided, which includes an acquisition unit that acquires work information about at least one of a calibration or an adjustment performed on the instrument in a plant; an extraction unit that extracts a plurality of data elements to be included in output information having a predetermined output format from the work information; and a generation unit that generates the output information from the plurality of data elements.

Disclosed herein as methods, apparatuses, non-transitory computer readable media, and systems for sensor calibration in at least one enclosure. The calibration may include self-calibration of the sensor, e.g., automatically. The calibration may be performed automatically at or after deployment of the sensor in the enclosure. The calibration may utilize the data of the sensor to be calibrated and/or sensor data of adjacent sensor(s) in the enclosure.
