Publication number: 20150218038Abstract: A method cleaving an end portion of an optical fiber involves providing a ferrule having a first end, a second end, and a ferrule bore extending between the first and second ends. An optical fiber is inserted through the ferrule bore so that an end portion of the optical fiber extends past an end face on the second end of the ferrule. At least one laser beam is emitted from at least one laser and directed to be incident on the end portion of the optical fiber at a first location. The at least one laser beam is emitted and directed to have a maximum beam width that is less than an outer diameter of the optical fiber at the first location so that the at least one laser can be operated to form a hole in the optical fiber at the first location.Type: ApplicationFiled: January 13, 2015Publication date: August 6, 2015Inventors: Joel Patrick Carberry, Anping Liu, Barada Kanta Nayak

Patent number: 9089931Abstract: Systems and methods for laser cleaving optical fibers are disclosed. In certain embodiments discussed herein, a ferrule of a fiber optic connector with an optical fiber disposed therein may precisely position an optical surface of the optical fiber when establishing an optical connection with another optical fiber. The optical surface may be thermally formed by laser beam(s) directed to an end face of the ferrule and to an end portion of the optical fiber extending therefrom. By having at least ninety (90) percent of the light incident on the ferrule as S-polarized light, the optical surface may be formed closer to the ferrule. This is because the laser beam may be more readily reflected away from the ferrule instead of being absorbed within the ferrule and thereby causing ferrule damage.Type: GrantFiled: March 11, 2013Date of Patent: July 28, 2015Assignee: Corning Cable Systems LLCInventors: Joel Patrick Carberry, Anping Liu, Barada Kanta Nayak

Patent number: 8833060Abstract: Embodiments for regenerating a particle filter are provided. In one example, a method includes operating a spark-ignition internal combustion engine having a particle filter for collecting and burning soot particles in exhaust gas comprises in order to initiate regeneration of the particle filter. The method may include, in response to a regeneration condition, increasing exhaust temperature by retarding spark timing and once regeneration is reached, operating the engine with lean combustion to regenerate the particle filter, where a degree of leanness is based on each of a state of the filter and an upstream three-way catalyst.Type: GrantFiled: February 22, 2012Date of Patent: September 16, 2014Assignee: Ford Global Technologies, LLCInventors: Helmut Hans Ruhland, Moritz Klaus Springer, Brendan Patrick Carberry

Patent number: 8820050Abstract: Embodiments for reducing ammonia slip are provided. In one example, a method for reduction of ammonia emissions from an engine exhaust gas aftertreatment device with an SCR catalyst comprises determining a concentration of NOx and/or ammonia in the exhaust gas aftertreatment device, comparing a determined value of NOx and/or ammonia concentration with a nominal value for NOx and ammonia, respectively, and if an actual or shortly forecasted ammonia concentration is above the respective nominal value, triggering engine conditions with higher exhaust NOx concentration. In this way, ammonia slip may be reduced without degrading fuel economy.Type: GrantFiled: June 14, 2012Date of Patent: September 2, 2014Assignee: Ford Global Technologies, LLCInventors: Alexey A.

The preform comprises a slotted cladding tube that surrounds a slotted, hollow-core PBG cane.

The fiber is used to form an environmental sensor for sensing the presence of a target substance in an environment. The slot formed in the PBG region of the fiber forms a ridge waveguide wherein a portion of the light that otherwise is confined to the hollow core as a bound mode travels in the slot.Type: ApplicationFiled: June 26, 2008Publication date: December 31, 2009Inventors: Joel Patrick Carberry, Leonard Charles Dabich, II, Michael Thomas Gallagher, Brett Jason Hoover, Karl William Koch, III, Joseph Edward McCarthy

Publication number: 20070241433Abstract: A semiconductor device package comprises a container including a base and sidewalls. The base is configured to support a semiconductor device chip, and a lead frame extends through at least one of the sidewalls. A portion of the lead frame within the sidewall has at least one aperture penetrating into the lead frame. The sidewall material extends into the aperture, thereby forming a strong interfacial bond that provides a low leakage, sidewall-lead-frame interface. The base has a reentrant feature that is positioned within the thickness of at least one of the sidewalls and engages the at least one sidewall, thereby forming a low leakage base-sidewall interface. The top surface of the base has a groove that is positioned within the thickness of at least one of the sidewalls and engages the at least one sidewall, thereby enhancing the low leakage base-sidewall interface.Type: ApplicationFiled: April 19, 2007Publication date: October 18, 2007Inventors: Patrick Carberry, Jeffery Gilbert, George Libricz, Ralph Moyer, John Osenbach, Hugo Safar, Thomas Shilling
