Latest Patents
Pontif's latest patents include a "Method of automatically requesting retransmission in a duplex digital" and a "Method and apparatus for digital data transmission with automatic repeat." The first patent introduces a go-back-N automatic repeat request method designed for duplex installations with noisy return channels. This method ensures that when an acknowledgment signal (ACK) is not correctly received, it is assumed to be positive until the Nth successive incorrectly received acknowledgment, which is treated as a negative acknowledgment. This approach guarantees that blocks are repeated even if acknowledgments are compromised by jamming. The second patent provides enough room in a transmitted frame to accommodate multiple useful information blocks, allowing for the recovery of excessive lateness that may occur due to successive repeats. The decoder in this system offers a confidence flag to the controlling microprocessor, enhancing the reliability of data transmission.
