    Abstract: A dynamic calibrating current sensor control system includes an input power supply that generates an input current and a current sensor interposed between the input power supply and the load. The current sensor is configured to output at least one current signal indicating a level of current delivered to the load. The dynamic calibrating current sensor control system also comprises an electronic switching control circuit that generates at least one control signal to selectively connect the input power supply to the load, and an electronic drift suppression circuit in signal communication with the current sensor and the switching control circuit. The drift suppression circuit is configured to generate a corrected current signal in response to applying an offset value to the current signal. The offset value cancels the drift current from the current signal in response to connecting the input power supply to the load.

    Abstract: An electronic circuit for processing signals from a strain gauge pressure sensor includes an anti-alias filter, an analog-to-digital conversion circuit, and a detection circuit for detecting when the sensor is unexpectedly disconnected from the signal processing circuit. The detection circuit provides a yes/no indication of the connection of the pressure sensor to the circuit based upon whether a common mode voltage associated with one of the signal terminals of the pressure sensor is out of range.
