Latest Patents

Among his recent innovations are two notable patents: the **Facility Type Determination Technique** and the **Technique for Reducing Echoes in Conference Communications**.

The Facility Type Determination Technique is designed to ascertain whether a facility connection is purely digital. This method involves transmitting a predetermined test signal composed of a pseudorandom sequence of digital signals through the connection once established. The received signal undergoes examination at the destination, allowing for a determination of the data transmission rate. This innovative technique is versatile and applicable across various data communication applications without restricting network facility management.

The second patent focuses on minimizing distortions and instabilities caused by echoes during conference communications. This is achieved through an echo estimating filter integrated into a conference bridging circuit, which combines received information signals with an echo compensation signal. The filter can be either fixed or adaptive, adjusting in response to received signals or training sequences, thus enhancing overall communication clarity.
