He holds a total of 5 patents, showcasing his innovative spirit and technical expertise. His work has had a lasting impact on how data is transmitted and monitored in complex systems.
Latest Patents
One of Hughes' latest patents is a "Data distribution network with improved broadcast feature." This invention allows a data source on a main local area network (LAN) to transmit broadcast messages via bridges to remote stations. A ring buffer in a bridge on the main LAN buffers a selected number of packets received from the data source. When the main bridge receives a 'Lost Frame Message' from a remote bridge, it can backtrack to the address of the lost packet in the ring buffer and retransmit it, ensuring seamless data flow. Additionally, if the buffer exceeds a pre-set limit, retransmission is slowed or halted until the buffer is cleared.
Another significant patent is the "Method of monitoring the bring up of all units in a multiple system." This procedure establishes the operability of a distributive data processing system by providing each terminal with a display featuring individually activatable indicators. These indicators represent the operational readiness of each terminal, and a series of operational tests are run to ensure functionality.
