A method includes receiving an output signal from a conductive element configured within a dielectric material. The conductive element can have an input voltage applied thereto and the output signal can include a plurality of signal amplitudes indicative of electric charges discharged across a gap between the conductive element and the dielectric material in response to the applied input voltage. The method can also include determining charge characterization data and classifying a material and a geometry of the conductive element and/or the dielectric material. The classification can include an operational state of the conductive element and/or the dielectric material. Related systems, apparatuses, and non-transitory computer readable mediums are also described.

Charge detection and quantization

A system including a sensor interface for determining a substitute frequency value via a sensor interface is provided. The system can include a first circuit receiving a frequency signal. The system can also include a sensor interface coupled to the first circuit and configured to determine a substitute frequency value based on the frequency signal. The system can also include a second circuit providing the substitute frequency value output from the sensor interface. The second circuit can provide the substitute frequency value in place of an analog input value by mimicking the behavior of an analog-to-digital converter. An apparatus including the sensor interface and methods of determining the substitute frequency value using a sensor interface are also provided.

Sensor interface

A sensor having a sensor head including a unibody construction, a first electrode, and at least one second electrode is provided. The first electrode can include a first pair of sensing elements coupled to each over via at least one bridge element extending from a first sensing element to a second sensing element. The at least one second electrode can include a second pair of sensing elements interleaved with the first pair of sensing elements. The second pair of sensing elements can be coupled to each other via at least one second bridge element extending from a third sensing element to a fourth sensing element. A method of manufacturing the sensor is also provided.

Impedance sensor

Sensor circuitry utilizing feedback to balance sensor output data is provided. An apparatus can include a primary coil and a first secondary coil outputting a first voltage. The apparatus can also include a second secondary coil outputting a second voltage. The apparatus can further include circuitry coupled to the first secondary coil and the second secondary coil. The circuitry can be configured to receive the first voltage from the first secondary coil and the second voltage from the second secondary coil. The circuitry can also be configured to determine a feedback voltage based on a difference between the first voltage and the second voltage. The feedback voltage can correct the difference. The circuitry can also modify a third voltage that can be output by the circuitry to be zero based on the feedback voltage.
