摘要： The present disclosure provides a troubleshooting system for current sensors including a motor, three current sensors and a controller. The three current sensors respectively sense three phase currents of the three-phase current of the motor to obtain three current sensing values. The controller is configured to control the three-phase current of the motor. When the sum of the three current sensing values is greater than a threshold, the controller controls the three phase currents to be zero, and a first offset sensor and a current offset are obtained. When the sum of the three current sensing values equals the current offset, a second offset sensor is obtained. If the first offset sensor and the second offset sensor are the same current sensor, the controller outputs a warning signal, if the first offset sensor and the second offset sensor are different current sensors, the controller controls the motor to stop operating.

摘要： A diagnostic Electrochemical Impedance Spectroscopy (EIS) procedure is applied to measure values of impedance-related parameters for one or more sensing electrodes. The parameters may include real impedance, imaginary impedance, impedance magnitude, and/or phase angle. The measured values of the impedance-related parameters are then used in performing sensor diagnostics, calculating a highly-reliable fused sensor glucose value based on signals from a plurality of redundant sensing electrodes, calibrating sensors, detecting interferents within close proximity of one or more sensing electrodes, and testing surface area characteristics of electroplated electrodes. Advantageously, impedance-related parameters can be defined that are substantially glucose-independent over specific ranges of frequencies. An Application Specific Integrated Circuit (ASIC) enables implementation of the EIS-based diagnostics, fusion algorithms, and other processes based on measurement of EIS-based parameters.

摘要： A method includes generating a reference voltage by periodically switching direction of current flow in a diagnostic sensor, where the reference voltage is a non-sinusoidal differential voltage of which an amplitude alternates between minimum and maximum values, and where the reference voltage includes a diagnostic sensor output voltage component responsive to an external magnetic field and a diagnostic sensor offset voltage component responsive to a mismatch of the diagnostic sensor. The method also includes amplifying the reference voltage to produce an amplified reference voltage, where the amplified reference voltage is a differential voltage having an amplifier offset voltage component. Additionally, the method includes demodulating the amplified reference voltage by filtering the diagnostic sensor offset voltage component and the amplifier offset voltage component to produce a demodulated voltage. Also, the method includes digitizing the demodulated voltage to produce a digitized voltage.
