Abstract: A method of detecting and locating a micro-interface abnormality within an electrical system having a plurality of conductors and a plurality of electrical connections includes identifying a subset of the plurality of electrical connections by detecting an acoustic signal within the electrical system and analyzing the detected acoustic signal and determining that the detected acoustic signal is indicative of an electrical fault, measuring a contact resistance of each of the subset of the plurality of electrical connections, and identifying at least one of the subset of the plurality of electrical connection points as having a micro-interface abnormality based on the measured contact resistances.

Abstract: The present invention is directed to system for current sensing including a first Hall effect sensor and a second Hall effect sensor constructed to provide feedback indicating current flow through a conductor susceptible to external magnetic flux. A housing is configured to position the first Hall effect sensor and the second Hall effect sensor about the conductor to provide generally magnitude equal feedback of the current flow through the conductor and generally polarity opposite feedback of the external magnetic flux.

Abstract: The present invention is directed to system and method for current sensing using an anti-differential, error correcting, current sensing system. The invention includes a conductive path configured to receive a current therethrough. A first current sensor is positioned on a first side of the conductive path and configured to monitor a first directional magnetic field induced by the current. A second current sensor is positioned on a second side of the conductive path, substantially opposite the first current sensor, and configured to monitor a second directional magnetic field induced by the current that is substantially opposite in direction to the first directional magnetic field. A processing component is configured to receive feedback from the first current sensor and the second current sensor and generate an anti-differential output from the feedback.
