Latest Patents

One of his latest patents is a "Supplementary information transmitting arrangement for a digital data." This invention relates to an arrangement for transmitting a digital supplementary information signal having a low rate alongside a digital data signal with a high rate. The insertion of the supplementary information in the data signal is based on modifying the accumulative disparity of the data signal according to the logic level of the supplementary information signal. In a first embodiment, parity check words are periodically inserted in the data signal, with their accumulative disparity depending on the comparison of the desired parity indicated by the logic level of the supplementary information signal. In a second embodiment, the parity check words correspond to the binary-to-ternary transcoding of a predetermined bit group of the data signal, which is scrambled into a pseudo-randomized signal with a constant accumulative disparity over a predetermined period.

Another significant patent is a "Monitoring system for telecommunication links equipped with two-way repeaters-regenerators." This system comprises a monitoring station that transmits information data and a low-frequency control signal through the forward link while receiving information data and supervisory words through the backward link. This setup monitors the performance of the repeaters-regenerators and identifies errors. Each repeater-regenerator stores a supervisory word in a shift register, with advance pulses obtained by frequency division of the low-frequency control signal. The supervisory word is completed by a start bit and a stop bit, modulating the low-frequency control signal, which is then transmitted to the monitoring station through the backward link.
