Title: Innovations by Christopher A Nicolls
Introduction
Christopher A Nicolls is a notable inventor based in Cumberland, Rhode Island, with a remarkable portfolio of five patents. His work primarily focuses on electrical safety and detection technologies, contributing significantly to advancements in the field.
Latest Patents
One of his latest patents is a low-cost arc fault detection technique. This invention includes an apparatus and methods for detecting arc faults, which enhances the discrimination of electrical events. The arc fault detection apparatus comprises a current sensor, a di/dt input sense circuit, a dv/dt input sense circuit, and a processing unit. The current sensor monitors power line current and provides high-frequency components to the di/dt input sense circuit. The dv/dt input sense circuit monitors power line voltage. Both input sense circuits generate signals that convey information about changes in power line current and voltage. The processing unit analyzes these changes to accurately discriminate between detected electrical arcing events and nuisance loads.
Another significant patent is the arc fault circuit interrupter test circuit and test board. This tester can selectively simulate and apply electrical arc faults and nuisance loads to a device under test (DUT). The tester includes a power supply, a test controller, and test circuitry that connects to the DUT. AC power input is provided to the DUT and the power supply, which regulates the AC power input to a DC level for powering the test controller. The test circuitry full wave rectifies AC current returning from the DUT, while the test controller manages a switch in the test circuitry. This setup allows for the simulation of both arcing and nuisance load conditions, verifying the proper operation of the DUT.
