Abstract: An interference removal technique, called Wavelet-Adaptive Interference Cancellation for Underdetermined Platforms (WAIC-UP), is provided to effectively eliminate stray magnetic field signals using multiple magnetometers, without requiring prior knowledge of the spectral content, location, or magnitude of the interference signals. WAIC-UP capitalizes on the distinct spectral properties of various interference signals and employs an analytical method to separate them from ambient magnetic field in the wavelet domain.

Abstract: A method for monitoring the operating state of a set of circuit breakers includes the steps of arranging on the wall of each circuit breaker a synchronous triaxial digital magnetometer on a semiconductor chip, cyclically and synchronously reading temperatures measured by the magnetometers and from the temperatures measured by the magnetometers and a value of the ambient temperature, determining, for each circuit breaker, whether an internal heating temperature of the circuit breaker reaches a first temperature threshold which may be representative of an anomaly of the operating state of the circuit breaker.

Abstract: A passive magnetic detection and discrimination system and method is disclosed. The system comprises at least one sensing structure having a plurality of magnetic inductive sensors arranged on a rigid framework; at least one screening area defined by one or more sensing structures, whereby the plurality of magnetic inductive sensors are configured to respond to a magnetized object passing thereby; and a processor and a memory operatively connected to the plurality of sensors and configured to receive data corresponding to amplitude waveforms created in each of the plurality of sensors by the magnetized object. Based on characteristic waveforms created by the magnetized object passing by the plurality of sensors, the system is configured to detect and discriminates the magnetized object. In another embodiment, the system utilizes an artificial intelligence or machine learning module to improve identification of a magnetized object based on the characteristic waveforms created by the magnetized object.

Abstract: Systems, methods, and apparatuses for measuring capacitance of a load. An apparatus includes a ground connector, an output connector configured to couple to the load, and a time-varying signal source configured to inject a time-varying voltage signal onto a conduction path between the ground connector and the output connector. A DC power source is configured to apply a DC offset to the time-varying voltage signal, and a current monitor is configured to measure time-varying current in the conduction path. A capacitance module is configured to determine the capacitance based upon at least one of the time-varying current and a frequency of the time-varying voltage signal.
