Design and Evaluation of a Directional Antenna for Ocean Buoys
A system concept has been developed by Viasat, Inc. and Woods Hole Oceanographic Institution for improving the data telemetry bandwidth available on ocean buoys. This concept utilizes existing communications satellites as data relay stations and mechanically steered antenna arrays to achieve increased data rates and improved power efficiency needed for ocean applications. This report describes an initial feasibility and design study to determine if a mechanically steered antenna array can meet the requirements of open ocean buoy applications. To meet the system requirements, an 18-element microstrip antenna (9-element transmit, 9-element receive) was designed and fabricated under subcontract...

Henry Frye
Henry E. Frye came of age just as the South was beginning a transformational change. When he graduated from college in 1953, African Americans like him could only hope that the future would be different from the past. At the close of his public career in 2001, he was chief justice of the North Carolina Supreme Court--the head of the state's third branch of government. Throughout their lives, Frye and his wife, Shirley, were in the vanguard of the advances that shaped the lives of African Americans. His election to the state legislature in 1968 was the beginning of steady, determined efforts to expand opportunities for African Americans in politics, business and society at large. This book traces, along with his career, the growing participation of African Americans in the civic, political and social life of North Carolina.
