Patent number: 8247028Abstract: A method of controlling the flow resistance of a fluid disposed on a surface of a substrate. The method comprises contacting a fluid with a plurality of cells on a substrate and adjusting amounts of a surfactant and a medium in the fluid to thereby form a foam layer contacting the walls of the cells. Each of the cells has at least one dimension that is less than about 1 millimeter and is configured to hold the medium therein. Each of the cells has walls that laterally enclose an area of a surface of the substrate and has a top opening. Bubbles of the foam layer have fluid walls that include a surfactant, are filled with the medium, and remain substantially stationary on the top openings of the cells for a period on average of at least about 1 minute.Type: GrantFiled: December 30, 2009Date of Patent: August 21, 2012Assignee: Alcatel LucentInventors: Marc Scott Hodes, Paul Robert Kolodner, Thomas Nikita Krupenkin, Todd Richard Salamon, Joseph Ashley Taylor

Patent number: 8249446Abstract: A method and apparatus for regulating rogue behavior in optical transmission devices. The apparatus, for example, may be implemented in one or more of the ONTs in a PON. The ONT includes an optical transmitter that may be disabled by a command generated by the ONT itself if rogue behavior is detected or suspected. To detect rogue behavior, at least one output indictor, such as LBC or MPC, is monitored during one or more monitoring windows. If monitoring indicates that the optical transmitter is transmitting more than a pre-determined threshold, a suspect rogue flag is set, for example in an I2C register. The register is read, preferably a number of successive times, and a determination is made whether to disable the optical transmitter. In some embodiments, the OLT is queried as part of this determination. The disability may be permanent, until a manual service operation, for example, or temporary.Type: GrantFiled: December 30, 2009Date of Patent: August 21, 2012Assignee: Alcatel LucentInventors: Joseph L. Smith, David G. Eckard
