With a single patent to his name, McCready's work exemplifies the ingenuity required to solve complex communication challenges in the ever-evolving world of telecommunications.
Latest Patents
W J McCready is credited with the patent for an "Automatic Sidetone Selector." This innovative invention enhances the functionality of a four-wire telephone station set that interfaces with a two-wire telephone line through a four-to-two wire hybrid circuit. The device automatically cancels the phase to a predetermined value, optimizing the impedance match between the telephone set and line. Under software control, a microcontroller mutes the telephone’s transmitter and receiver during idle intervals and substitutes a tone signal generator to produce a sidetone signal. This signal is processed through a full-wave rectifier and peak voltage detector to create a sidetone envelope. By sequentially connecting several impedance balancing networks, the invention allows for a digital encoding and storage of sidetone envelopes. The minimum sidetone value corresponding to the optimum impedance match is then retained, ensuring outstanding performance unless changed by subsequent calls.
