Patent number: 11962044Abstract: The present invention offers some general specifications for the design, assembly, and adaptation of a rotating cylinder electrochemical cell into an autoclave, of a high temperature and pressure system for corrosion studies that simulate operating conditions in pipelines, as well as the operation and safety of an autoclave to evaluate the electrochemical process of metal surfaces exposed to aggressive aqueous solutions. The electrochemical cell consists of an array of three electrodes that include a rotating cylinder electrode designed to operate hermetically, a reference electrode and an auxiliary electrode. The rotating cylinder electrode is considered to be the working electrode, where the oxidation and electrochemical reduction processes are studied. However, the use of the method described in this work can be extended to other testing environments and materials by taking into account the physical and chemical properties of the fluids and materials to be used in order to avoid any risk for the operator.Type: GrantFiled: November 30, 2020Date of Patent: April 16, 2024Assignee: INSTITUTO MEXICANO DEL PETROLEOInventors: Eliceo Sosa Hernandez, Marco Antonio Dominguez Aguilar, Hongbo Liu, Jorge Luis Alamilla Lopez, Jorge Flores Castillo, Marco Antonio Hernandez Rojo, Ivan Velazquez Ovando, Cesar Mendez Romero, Luis Manuel Quej Ake

Patent number: 10542336Abstract: A method and apparatus for optimizing optical transport using a software defined network (SDN) controller are disclosed herein. The SDN controller may define a margin optimization function based on at least one optical system performance metric. The function may include at least one related initiation criterion. Further, the SDN controller may collect at least one measurement for the performance metric. The measurement may include an assessment of deployed carriers not carrying client data. The SDN controller may determine whether the initiation criterion is met based on at least one collected measurement. The SDN controller may select a system margin optimization mechanism and define a system margin optimization threshold criterion on a condition that the initiation criterion is met. The SDN controller may determine whether the optimization threshold criterion is met. The SDN controller may implement one or more optimization events on a condition that the optimization threshold criterion is met.Type: GrantFiled: March 9, 2018Date of Patent: January 21, 2020Assignee: Infinera CorporationInventors: Loukas Paraschis, Harshad Sardesai, Abhinava Shivakumar Sadasivarao, Parthiban Kandappan, Marco Sosa

The SDN controller may define a proactive protection threshold criterion based on based on a plurality of optical system performance metrics and may collect at least one measurement for each of the metrics. The SDN controller may then determine whether the proactive protection threshold criterion is met based on at least one of the collected measurements. Further, the SDN controller may select a protection mechanism and define a protection threshold criterion on a condition that the proactive protection threshold criterion is met. Also, the SDN controller may initiate proactive protection events based on the selected protection mechanism. The SDN controller may determine whether the protection threshold criterion is met.
