Latest Patents
One of McGinn's latest patents is a line interface circuit designed for coupling signals between a telephone line and a hybrid circuit. This circuit includes a loop driver circuit that supplies energizing current to the telephone line while driving it with alternating current signals. A loop current detector generates a voltage signal in response to current flow in the telephone line. Additionally, amplifier circuits respond to differential signals on the telephone line and signals from the hybrid circuit to generate a composite signal. This composite signal, along with the voltage signal, is combined in a network that controls the operation of the loop driver circuit, ensuring the telephone line is terminated with a preferred impedance.
Another significant patent is related to high voltage converters. These converters feature at least a pair of transistor switches located on the secondary windings of a flyback transformer. The switches are controlled to be conducting, variably conducting, and non-conducting, allowing for controlled power flow between the transformer and a load. Various configurations of a connection switch network are also disclosed in this patent.
