    Abstract: A corrosion sensor for detecting the action of corrosive media on a metallic component when the sensor is mounted in the vicinity of the metallic component in use is disclosed. The sensor includes an electrically conducting corrodible element mounted on a non conducting substrate, the corrodible element being covered with a protective coating such as paint adapted to protect the corrodible element from corrosive media. The protective coating defines a temporary feature such as a paint defect which extends across the corrodible element and is designed to permit attack on the corrodible element by corrosive media after a predetermined period of time. The corrodible element comprises a pair of spaced tracks extending generally in a longitudinal direction and a series of corrodible tracks, each corrodible track extending generally in a lateral direction and forming an electrical connection between the spaced tracks. The temporary feature extends longitudinally, in the space between the pair of tracks, across a number of the corrodible tracks whereby to permit a corrosive attack on a number of the corrodible tracks after the predetermined period of time.

    Abstract: A closed-loop calibration scheme is configured to allow a device to remain in continuous operation. A signal generator device provides a pseudorandom sequence for a signal received by a magnetic field magnetic field sensor, such as a Hall-effect sensor. A signal decoder circuit receives the output signal and decouples the generated spread spectrum signal from the interference by measuring the gain in the overall signal. The decoder device distinguishes the known spread spectrum signal from any perturbation effects of particular bandwidths. A processing circuit then outputs a signal that has an operation parameter that has been adjusted to compensate for the perturbation effects. The processing circuit provides the receiver circuit with the compensation signal, hence forming a closed-loop calibration configuration.

    Abstract: Measuring a sample includes providing a magnetic field at the sample using an electromagnetic field resonator. The electromagnetic field resonator includes two or more resonant structures at least partially contained within dielectric material of a substrate, at least a first resonant structure configured to provide the magnetic field at the sample positioned in proximity to the first resonant structure. The sample is characterized by an electron spin resonance frequency. A size of an inner area of the first resonant structure and a number of resonant structures included in the electromagnetic field resonator at least partially determine a range of an operating resonance frequency of the electromagnetic field resonator that includes the electron spin resonance frequency. Measuring the sample also includes receiving an output optical signal from the sample generated based at least in part on a magnetic field generated by the electromagnetic field resonator.

    Abstract: An abnormality detection device includes: a coupling-capacitor having a first-end and a second-end coupled with a high-voltage circuit; a signal output unit; a signal extraction unit; and a signal input unit. The signal output unit is coupled with the first-end of the coupling-capacitor via a detection-resistor, and outputs an alternating-current inspection-signal. The signal extraction unit extracts the inspection-signal, as an extraction-signal, output between the detection-resistor and the coupling-capacitor. The signal input unit detects abnormality of insulation resistance of the high-voltage circuit based on a level of the inputted extraction-signal. The signal extraction unit includes a signal removing filter and a subtraction circuit. The filter removes a signal equal in frequency to the inspection-signal and passes low-frequency noises lower in frequency than the inspection-signal. The subtraction circuit outputs a differential signal, as the extraction-signal, between a signal having passed through the filter and a signal not having passed through the filter.
