ALEXANDRIA, Va., March 3 -- United States Patent no. 12,566,220, issued on March 3, was assigned to VoltServer Inc. (East Greenwich, R.I.).

"Method for detecting a series resistance fault in a digital-electricity transmission system" was invented by Stephen S. Eaves (Charlestown, R.I.).

According to the abstract* released by the U.S. Patent & Trademark Office: "In a digital-electricity power system, an electrical-current sample value is acquired along with a voltage sample value within a time window over which the electrical current and voltage are substantially unchanged. A transmission-line series voltage is derived from the difference between the voltage at the transmitter and the voltage at the receiver. Each transmission-line series ...
