Title: Brian Clifford McKinney: Innovator in Telecommunications
Introduction
Brian Clifford McKinney is a notable inventor based in Calgary, Canada. He has made significant contributions to the field of telecommunications, holding a total of 5 patents. His work focuses on enhancing communication systems, particularly through innovative telephone technologies.
Latest Patents
One of McKinney's latest patents is for a key telephone system without common control. This multi-line key telephone system does not require a key service unit and includes three analog telephone lines. Up to eight, three-line telephones can be connected to provide enhanced service features while maintaining cost-effectiveness. The system ensures reliability despite the power dependency of the telephones by incorporating POTS telephones, which provide uninterrupted essential telephone service during power outages.
The system facilitates both data and voice communications between multiple three-line telephones by converting an input digital bit stream from either a digital or analog source into an out-of-band binary FSK radio frequency output signal. This signal is communicated between the three-line telephones as data packets within a TDM frame, allowing analog voice communications to proceed without interference. The initiating telephone acts as a master station, establishing synchronous inter-station communications at the frame level and asynchronous communications at the packet level. The called telephone functions as a slave station, synchronized to the master station's time slots. Temporary data storage in firmware buffers and controlled timing at both stations allows them to operate effectively within their respective TDM frame time slots.
Career Highlights
Throughout his career, McKinney has worked with prominent companies in the telecommunications industry, including Nortel Networks Corporation and Northern Telecom Limited.
