Abstract: A current-sensing system for fault detection includes a sensing element for detecting a magnetic field and a magnetic core that encloses at least two target conductors. The sensing element is mechanically uncoupled from the magnetic core, and it is designed to detect a component of the magnetic field superposition by currents in the target conductors, the field being generated inside the core and traversing an opening in the core. The sensing element provides an output signal indicative of this superposition. The system is able to detect the combined magnetic field effects of multiple currents, enabling accurate fault detection in electrical systems.

Abstract: A method comprises receiving an input signal for processing in one or more neurons of a neural network, wherein the neural network has zero bias neurons and includes a plurality of resistive processing unit (RPU) weights and each neuron has an activation function.
