Patent number: 10079676Abstract: Systems and methods for restoring or recovering linear polarization state of an optical signal as it exits the far end of an optical fiber are disclosed. The optical signal may have an expected pattern of polarization states through a birefringent material of the optical fiber from a first node to a second node. The optical signal may be received by the second node and resulting polarization states may be measured. In certain non-limiting examples, the measured polarization states may be compared to expected polarization states to determine a characterization angle indicative of an axis of the optical fiber.Type: GrantFiled: July 11, 2014Date of Patent: September 18, 2018Assignee: The Board of Regents of the University of OklahomaInventors: Nikhil Vishnu Punekar, Pramode Verma, Gregory Macdonald, Bhagyashri Arun Darunkar, Mayssaa El Rifai

Patent number: 8247755Abstract: A light surface display for providing a three-dimensional image including a plurality of particles dispersed within a volumetric display. A first projection system projects sequential slices of electromagnetic energy of one or more infrared wavelengths along the length and width of the volumetric display energizing particles to form a two-dimensional image. A second projection system projects translational slices of electromagnetic energy of one or more infra-red wavelengths that intersect with the energized particles across the depth of the volumetric display.

Publication number: 20080080382Abstract: The DiffServ architecture is an increasingly preferred approach for providing varying levels of Quality of Service in an IP network. This discovery presents a new framework for improving the performance of the DiffServ architecture where heterogeneous traffic flows share the same aggregate class. The new framework requires minimal modification to existing DiffServ routers by adding a second layer of classification of flows based on their average packet sizes and using Weighted Fair Queueing for flow scheduling. The efficiency of the new framework is demonstrated by simulation results for delay, packet delivery, throughput, and packet loss, under different traffic scenarios.Type: ApplicationFiled: September 28, 2007Publication date: April 3, 2008Inventors: Mostafa Dahshan, Pramode Verma, James Sluss
