Patent number: 8718416Abstract: A novel micro-optical electric field sensor exploits morphology-dependent shifts of the optical modes of dielectric cavities to measure temporally- and spatially-resolved of electric field with extremely high sensitivity. The measurement principle is based on the electrostriction effect on the optical modes of dielectric micro-resonators (or micro-cavities) and exploits recent developments in optical fiber and switching technologies. The optical modes are commonly referred to as “whispering gallery modes” (WGM) or “morphology dependent resonances” (MDR). By monitoring the WGM shifts, the electric field causing the electrostriction effect can be determined. Different sensitivities and measurement ranges (maximum measured electric field) can be obtained by using different cavity geometries (for example solid or hollow spheres), polymeric materials (PMMA, PDMS, etc) as well as poling the dielectric material.Type: GrantFiled: November 3, 2010Date of Patent: May 6, 2014Assignee: Southern Methodist UniversityInventors: Tindaro Ioppolo, Volkan Otugen, Ulas Ayaz

Patent number: 8695214Abstract: A network and method of laying network cables in water supply pipes is disclosed. A building is situated near a roadway along which is laid a trunk cable. A water supply pipe branches off the water main to enter the building. A water supply pipe is provided at the time of construction of the building and is an underground pipe. It is conventional to provide a dedicated (and usually underground) conduit for a branch cable, which is expensive and disruptive. In the present invention the branch cable is laid along water supply pipe, enabling the cable to cross between the trunk cable and the building with minimal disturbance of the ground therebetween. This is achieved by introducing cable to pipe by use of a suitable Y-junction at location and removing the cable from the pipe by use of a second such Y-junction at location.Type: GrantFiled: September 11, 2009Date of Patent: April 15, 2014Assignee: CMS (Cable Management Supplies) PLC. a Company of the United KingdomInventor: Elfed Thomas

Patent number: 8693823Abstract: Taught is a photonic crystal three-port circulator, which comprises a dielectric background material and a plurality of first air columns which are symmetrically arranged in the form of triangular lattice in the dielectric background material. The photonic crystal three-port circulator also comprises a magneto-optical cavity and three waveguides, wherein the magneto-optical cavity is arranged at the center of the photonic crystal three-port circulator; the three waveguides are symmetrically distributed around the magneto-optical cavity; and each waveguide comprises a waveguide port which is arranged at the position in the waveguide far away from the magneto-optical cavity. The photonic crystal three-port circulator realizes circular light transmission in single rotational direction from any one of the waveguide ports to another next to it, has a simple and compact structure, and can be easily integrated with other photonic crystal devices.Type: GrantFiled: November 29, 2010Date of Patent: April 8, 2014Assignee: Shenzhen UniversityInventors: Zhengbiao Ouyang, Qiong Wang

Patent number: 8684765Abstract: A connector assembly that includes a receptacle connector and a light pipe. The connector is configured to receive a removable device inserted along a longitudinal axis. The connector has a side surface that extends along a plane defined by the longitudinal axis and a vertical axis that is perpendicular to the longitudinal axis. The connector includes a ledge and a positive stop that project laterally outward from the side surface. The ledge has a ledge surface that joins the side surface. The light pipe extends substantially along the longitudinal axis. The light pipe has an inward-facing surface that is substantially flat throughout and abuts the side surface of the connector. The light pipe rests upon the ledge surface and the positive stop is positioned on the side surface to block the light pipe from moving in at least one direction along the longitudinal axis.Type: GrantFiled: October 31, 2008Date of Patent: April 1, 2014Assignee: Tyco Electronics CorporationInventors: Michael Eugene Shirk, Michael J. Phillips, David S. Szczesny

Patent number: 8678671Abstract: A tool for cleaving a plastic optical fiber has a body with a cleaving aperture at the insertion face of the body and through which the termination end section of the plastic optical fiber is inserted and in which an operative section is positioned upon inserting the plastic optical fiber into the tool. A cutting blade has a cutting edge and is moveable along a cutting path between a first operative position at which the cutting edge is spaced from the cleaving axis and a second operative position at which the cutting edge intersects the cleaving axis to cleave the plastic optical fiber to create an optical finish on an end surface of the operative section of the plastic optical fiber. A clearance region is located at the termination face of the body and generally aligned with the cleaving aperture and in which the termination end section may deflect upon engagement of the cutting blade with the plastic optical fiber.Type: GrantFiled: February 23, 2009Date of Patent: March 25, 2014Assignee: Molex IncorporatedInventors: Paul M. Mulligan, Carl Lindenmeyer, Stephen Migo, Thomas R. Marrapode

Patent number: 8682130Abstract: A package structure and method of packaging for an interferometric modulator. A thin film material is deposited over an interferometric modulator and transparent substrate to encapsulate the interferometric modulator. A gap or cavity between the interferometric modulator and the thin film provides a space in which mechanical parts of the interferometric modulator may move. The gap is created by removal of a sacrificial layer that is deposited over the interferometric modulator.Type: GrantFiled: September 13, 2011Date of Patent: March 25, 2014Assignee: QUALCOMM Mems Technologies, Inc.Inventors: Lauren Palmateer, William J. Cummings, Brian Gally, Mark Miles, Jeffrey B. Sampsell, Clarence Chui, Manish Kothari

Patent number: 8676840Abstract: A network's evolution is characterized by graph evolution rules. A graph, formed by merging multiple graphs representing the multiple snapshots of the network, that represents an evolutionary network is mined to identify evolutional patterns of the network. A pattern is selected from the identified patterns. Graph evolution rules are generated using identified evolutional patterns. The generated graph evolution rules represent the evolutional patterns of the network, the rules indicating that any occurrence of a child pattern of the selected pattern implies a corresponding occurrence of the selected pattern.Type: GrantFiled: June 6, 2012Date of Patent: March 18, 2014Assignee: Yahoo!

Patent number: 8676012Abstract: A fiber optic cable includes a polymeric jacket defining an outer periphery and a cavity interior thereto, an optical fiber positioned within the cavity, and first and second longitudinal strength elements fully embedded in the jacket on opposite sides of the cavity from one another, where the strength elements define a bend axis of the cable passing there through that is orthogonal to the length of the cable, and the bend axis and the length of the cavity define a preferential plane for bending. The cable resists bending about a third axis that is orthogonal to the length of the cable and the bend axis, where the third axis and the length of the cable define a non-preferential plane for bending. The difference in flexural rigidity between the preferential and non-preferential planes limits formation of spontaneous knots in a coil of the cable while providing flexibility for ease of handling.Type: GrantFiled: July 26, 2012Date of Patent: March 18, 2014Assignee: Corning Cable Systems LLCInventors: Mark Alan Bradley, William Welch McCollough, James Arthur Register, III
