To provide an abnormality detection apparatus for resolver which can determine the abnormality of at least the first system, even if the period of the excitation AC voltage of the first system and the period of the excitation AC voltage of the second system are different periods, and the magnetic interference between systems occurs. An abnormality detection apparatus for resolver applies an AC voltage of a first period to a first system excitation winding; applies an AC voltage of a second period different from the first period to a second system excitation winding; calculates DC values of first system two output signals by performing a DC extraction processing; and determines abnormality of first system based on whether or not the DC values of first system two output signals are within a normal range.

To provide a technique capable of facilitating water quality sensor calibration and drainage operations for improving water quality even when water quality monitoring devices and drainage devices are installed in places where operation is difficult, such as inside manholes. In a case of a deviation between a manual analysis value obtained at a water quality monitoring device (water quality sensor) installation site and the water quality measurement value (e.g., residual chlorine concentration) measured by the water quality monitoring device, a calibration value obtained based on the manual analysis value is stored in a cloud database via a communication terminal (communication unit) and network, and the water quality monitoring device downloads (acquires) this calibration value, and calibrates the water quality sensor based on the calibration value. Additionally, water quality can be improved by remotely managing drainage operations and controlling the start and stop of drainage operations according to the water quality.

A computing system located on-board a vehicle processes the input sensor data to obtain a downsampled representation of one or more time-series measurements. The computing system further identifies one or more characterization parameters to be reported as supplemental information along with the downsampled representation. The computing system processes the input sensor data to obtain a characterization value for each characterization parameter identified based on measurement conditions and communicates the characterizations based on a timing profile. The computing system formats the one or more characterization values to be reported along with the downsampled representation into one or more report messages. The computing system transmits the one or more report messages over a wireless wide area network directed to a server system. The one or more characterization values may be used by the server system as supplemental information in reconstructing the input sensor data from the downsampled representation.
