Patent number: 11221376Abstract: A load bank for testing power sources includes a load resistor assembly having a plurality of resistors which can be switched between wye and delta configurations for testing a variety of voltages and power sources requiring various load applications. First and second power connections are connected with primary and redundant power sources and a relay alternately connects the first and second power connections with the load resistor assembly for alternately testing the primary and redundant power sources while maintaining the sources electrically isolated. A damper is arranged adjacent the load resistor assembly and is operable between an open position which permits cold air to be delivered to the load resistor assembly to cool the assembly when the load bank is operating and a closed position which prevents hot air from being recirculated when the load bank is not operating.Type: GrantFiled: December 22, 2020Date of Patent: January 11, 2022Assignee: COMRENT INTERNATIONAL, LLCInventors: Joseph Morin, Brian Kelleher, Lowell Seal, Brett Gidge, Todd Locker, Graham Thompson

Patent number: 7196838Abstract: Repeaters for use in amplifying optical data signals transmitted through undersea fiber optic cables are disclosed. Raman amplification schemes using 100 or more pump lasers are integrated into industry standard sized pressure vessels for amplifying optical data signals transmitted through one or more fiber optic pairs. Such repeaters include high density packaging to permit numerous active and passive optical components, as well as significant lengths of optical fiber, to reside within legacy sized pressure vessels.Type: GrantFiled: December 6, 2001Date of Patent: March 27, 2007Assignee: Dorsal Networks, Inc.Inventors: Robert M. Adams, Sr., Lowell Seal, Brent R. Pohl, Brett Goldstein
