Title: The Innovations of Norman J Donaghue

Introduction

Norman J Donaghue is a notable inventor based in Reston, Washington. He has made significant contributions to the field of digital data systems, particularly with his innovative patent that enhances data service capabilities.

Latest Patents

Donaghue holds a patent for a "Multiport - multipoint digital data service." This invention provides a method and apparatus for delivering multipoint multiport service in a Digital Data System (DDS). The technology compensates for differences in time delays through the network by employing an alignment training process. This process measures delays from each remote station at a Central station, which then determines the necessary delay to insert at each remote station. By instructing the remote stations to insert these delays, Donaghue's invention ensures that all inbound data is aligned in time. This alignment prevents data errors when the data is combined within the network by the Multipoint Junction Units (MJU). The aligned frames are combined in the MJU operating in data mode through a logical AND operation, allowing marks transmitted by inactive ports to be combined with data from active ports, resulting in a composite signal sent to the Central Data Service Unit (DSU).
