Title: The Innovative Mind of Marc Darmon: A Review of His Contributions
Introduction: Marc Darmon, a prolific inventor based in Paris, France, has made significant contributions to the field of telecommunications through his innovative inventions. With a total of seven patents to his name, Darmon has focused on developing methods and devices that enhance communication technologies.
Latest Patents: Among Marc Darmon's latest patents is a method of automatically requesting retransmission in a duplex digital system. This go-back-N automatic repeat request method is designed for use on a duplex installation, especially in environments with noisy return channels. The ingenuity of this patent lies in its approach to handling acknowledge signals (ACK); when an ACK is not correctly received, it is provisionally assumed to be positive until the Nth successive acknowledgment is incorrectly received, which is then treated as a negative acknowledgment. This mechanism ensures that data blocks are repeated, even in the presence of jamming or interference. Additionally, Darmon has patented a method of coherent demodulation for phase shift keying, further showcasing his expertise in advanced communication techniques.
