Title: The Innovations of Guy J Fortier
Introduction
Guy J Fortier is a notable inventor based in Kanata, Canada. He is recognized for his contributions to telecommunications technology, particularly in the area of telephone systems. His innovative approach has led to the development of a unique patent that enhances the functionality of telephone sets.
Latest Patents
Fortier holds a patent for an "Automatic Sidetone Selector." This invention addresses the sidetone in a four-wire telephone station set that is coupled to a two-wire telephone line through a four-to-two wire hybrid circuit. The system automatically cancels the phase to a predetermined value, which is set by incrementally adjusting a balancing impedance connected to the circuit. This adjustment ensures an optimum impedance match between the telephone set and the line is achieved. Under software control, during idle intervals between dialed digits when a call is initiated, a microcontroller mutes the telephone transmitter and receiver on the telephone side of the circuit. It substitutes these components with a tone signal generator to produce a sidetone signal that is applied to a full-wave rectifier and subsequently to a peak voltage detector to generate a sidetone envelope. Individual impedance balancing networks are sequentially connected to the telephone side of the circuit, and the sidetone envelope for each balancing impedance is digitally encoded and stored. A mutual comparison of the stored data indicates a minimum sidetone value, which corresponds to an optimum impedance match that is retained unless a subsequent telephone call results in a change of balancing impedance.
