A method of a charging calibration system is mainly to charge/discharge a reference touch pad, then to compute a reference charging time needed for a number of accumulated reference supply duties to reach a reference charging number, then to base on the reference charging time to charge/discharge one of operation touch pads repeatedly by a calibration supply duty, finally to count a number of the experienced calibration supply duties within the reference charging time. Thereupon, a reference charged number of an individual operation touch pad within the reference charging time can be obtained. Thus, the operation touch pad can adjust the reference charging time to meet various environmental requirements. Also, the reference supply duty is greater than the calibration supply duty.

A method for automatically calibrating a rocker-type sensor module having a position or acceleration sensor involves measuring a position of the sensor module as an angle relative to a fixed spatial direction, and outputting an output signal that depends on whether the measured angle is less than or greater than a switching angle. The output signal is set to a first output value if the measured angle exceeds the switching angle. The switching angle is set to a value corresponding to the measured angle minus an “off” free pivot angle, as long as the value of the measured angle continues to increase. The output signal is set to a second output value if the measured angle falls below the switching angle. The switching angle is set to a value corresponding to the measured angle plus an “on” free pivot angle, as long as the value of the measured angle continues to fall.

A system and method for determining if a field calibration of a subject sensor associated with a vehicle is warranted, and calibrating the subject sensor using a sensor associated with another vehicle when calibration is warranted. Reference vehicles may perform predetermined maneuvers in order to provide additional measurements for use during calibration.

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 device that includes a sensor unit and a processing unit. The sensor unit is configured to detect at least one measured value at a predetermined point in time. The processing unit is configured to carry out a self-calibration of the device as a function of the detected measured value. A method for self-calibration of a device is also described.

Various examples are directed to systems and methods for managing a sensor. A measurement system may receive, from a host device, a first register map describing a first configuration of a measurement system. The first configuration may be associated with a first sensor. The measurement system may compare the first register map to an error rule set indicating inconsistent register map arrangements. After comparing the first register map to the error rule set, the measurement system may configure a switch matrix of the measurement system to sample the first sensor according to the first configuration of the measurement system. The measurement system may receive a plurality of samples from a first sensor and generate first digital measurement data based at least in part on the plurality of samples.

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.

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.
