Abstract: Applying a bias magnetic field to a solid-state spin sensor enables vector magnetic field measurements with the solid-state spin sensor. Unfortunately, if the bias magnetic field drifts slowly, it creates noise that confounds low-frequency field measurements. Fortunately, the undesired slow drift of the magnitude of the bias magnetic field can be removed, nullified, or cancelled by reversing the direction (polarity) of the bias magnetic field at known intervals. This makes the resulting solid-state spin sensor system suitable for detecting low-frequency (mHz, for example) changes in magnetic field or other physical parameters.

Abstract: Techniques for environmental contaminant monitoring are disclosed. In some embodiments, a contaminant detection system electronically instigates a test circuit that shares an environment with another circuit to induce an electrical anomaly in the test circuit when environmental contamination is present. While electronically instigating the first circuit, the contaminant detection system monitors for an electrical anomaly indicative of the environmental contamination. Responsive to detecting an electrical anomaly in the test circuit that is indicative of environmental contamination, the contaminant detection system generates an alert that indicates that the second circuit has likely been exposed to the environmental contamination. The contaminant detection system may provide early warning of potentially caustic environments before creep corrosion or similar phenomena manifest in expensive hardware resources. Thus, hardware outages may be mitigated or avoided.
