Latest Patents

One of Brian's latest patents is titled "Arc fault detection through mixed-signal machine learning and neural networks." This invention involves a circuit interrupting device that includes a line terminal, a wideband current sensor, a zero cross detection circuit, and a microcontroller. The microcontroller applies a digital filter to the line current measurement signal and estimates the spectral density of the filtered signal. It calculates an arcing characteristic based on this spectral density and determines the presence of an arc fault, activating the interrupting device when necessary.

Another notable patent is the "Ground fault circuit interrupter with integrated controller." This device consists of a phase conductor, a neutral conductor, and an interrupter that disconnects these conductors from a load. The microcontroller in this device generates a reference signal and determines if the difference between the first signal from the sensor and the reference signal exceeds a threshold. It activates the interrupter when the conditions are met, ensuring safety in electrical systems.
