Latest Patents

Among his impressive array of patents, two stand out for their innovative approaches:

1. **Multilevel Multiplexing** - This patent describes a synchronous PCM digital transmission system that incorporates multilevel multiplexing. The system interleaves two or more tributary signals, which in turn consist of a multiplexed plurality of subtributaries. It introduces a unique auxiliary frame pattern or byte (F.sub.T) that can slide within subscriber-defined frames, ensuring synchronization across multiplexers. This design not only facilitates multiplexer framing but also delivers high-speed multiplexed signals that align with the system clock rate, utilizing simpler circuitry compared to other existing designs.

2. **Dual Mode Coding** - This invention presents a dual mode encoding and decoding technique specifically aimed at digital systems where transmitted digital words must adhere to a prescribed bit limit. The coding occurs in two modes: the first leverages predictive differential coding for enhanced precision, while the second guarantees a minimum level of precision within the allotted bits. This approach is particularly applicable in the transmission of color video signals, ensuring high-quality output.
