Title: Joseph F. Darveau: Innovator in Telephone Line Technology
Introduction
Joseph F. Darveau is a notable inventor based in Aylmer, Canada. He has made significant contributions to the field of telecommunications, particularly in the area of telephone line technology. With a total of 2 patents, his work has had a lasting impact on the industry.
Latest Patents
Darveau's latest patents include a method of providing direct current (d.c.) feed to a telephone line. This innovative approach involves a two-wire telephone line that is supplied with d.c. feed from a drive circuit, which includes two amplifiers. These amplifiers supply a transmission signal to the line, and the output potentials determine a loop current that is monitored to control the supply voltage for the drive circuit. The design allows for rapid response to high loop currents while maintaining stable operation.
Another significant patent focuses on the protection and recovery of telephone line interface circuits. This automatic method monitors current on the line and interrupts the connection in the event of excessive current. The interface circuit then monitors common mode voltage and reconnects based on specific voltage thresholds. This method enhances protection and facilitates rapid recovery from faults on the telephone line.
