Latest Patents

Irving M McNair, Jr. holds a patent for a "Miniature bridge lifter for telephone lines." This invention is a miniature electronic bridge lifter designed for bridged telephone lines. It can be mounted directly on the protector unit in the central office. The device includes an impedance inserted serially in each side of the loop, isolating nonactive loops from the central office termination. It switches to a low impedance connection whenever a party on one of the bridged line connections goes off-hook. A combination semiconductive and resistive voltage divider detects the voltage across the loop. The resistive component serves as the only cross-coupling between the telephone lines. When the line voltage falls below a preselected threshold, indicating that the connected party has gone off-hook, a switch operates to bypass the series impedances and establish a low-loss path to the common line. This patent showcases his innovative approach to solving practical problems in telecommunications.
