Publication number: 20180094786Abstract: The invention introduces converging lenses connecting with optical fibers and a device for receiving sunlight that uses these lenses to converge sunlight from every angle of the sun during the day and the collected light beam at the output is quite parallel. To converge light from every angle of the sun, without using any motion part, small lenses are arranged to build a convex surface. Sunlight collected by these lenses become a parallel light beam and are guided by optical fibers. These optical fibers are arranged tightly to build a bundle of optical fibers in order to make it easier to further transmit and to use at the output of the device.Type: ApplicationFiled: October 12, 2017Publication date: April 5, 2018Applicant: University of Science, Vietnam National University - HanoiInventors: Thuat Tran Nguyen, Hieu Chi Hoang, Quan Duc Ho, Quan Quang Nguyen, Hai Hoang Nguyen

Patent number: 8401994Abstract: A plurality of mid-tier databases form a single, consistent cache grid for data in a one or more backend data sources, such as a database system. The mid-tier databases may be standard relational databases. Cache agents at each mid-tier database swap in data from the backend database as needed. Consistency in the cache grid is maintained by ownership locks. Cache agents prevent database operations that will modify cached data in a mid-tier database unless and until ownership of the cached data can be acquired for the mid-tier database. Cache groups define what backend data may be cached, as well as a general structure in which the backend data is to be cached. Metadata for cache groups is shared to ensure that data is cached in the same form throughout the entire grid. Ownership of cached data can then be tracked through a mapping of cached instances of data to particular mid-tier databases.Type: GrantFiled: September 18, 2009Date of Patent: March 19, 2013Assignee: Oracle International CorporationInventors: Chi Hoang, Tirthankar Lahiri, Marie-Anne Neimat, Chih-Ping Wang, John Miller, Dilys Thomas, Nagender Bandi, Susan Cheng

Patent number: 7479056Abstract: An automated drill bit sharpening and verification system employing one or more electronic optical assemblies for gathering orientation data of a drill bit to be sharpened. The drill bit is rotated and aligned to a grinding assembly based on the orientation data. The orientation data of the drill bit may be gathered by illuminating a cutting tip of the drill bit with an illumination ring. Additionally, the orientation data of the drill bit may be gathered by capturing two views (e.g., orthogonal views or front and side views) of the cutting tip of the drill bit.Type: GrantFiled: February 8, 2007Date of Patent: January 20, 2009Assignee: Kycera Tycom CorporationInventors: Paul D Mortell, Chi Hoang, David M. McElrone, Gary P Erpenbeck, Walter James Frandsen, Jr., Charles Shafee Slemon

Patent number: 7467163Abstract: An Enterprise Server Data Management System provides for the handling of large data objects (LOB) according to the data size required for the large object. Methods are provided to find a particular object that is stored or to delete such an object. But particularly the method arranges for data storage of Large Objects in a structured database, depending on the number of kilobytes forming the Large Object (LOB).Type: GrantFiled: February 10, 2006Date of Patent: December 16, 2008Assignee: Unisys CorporationInventors: James Allen Dodds, Kung Yi Lin, Johnny Hu, Alma Navarro de Jesus, Vikki Mei-Whey Lai, Courtney Chi Hoang, Minh-Nguyet Tran, Subramaniam Ramamurthi, Valerie Renee Schmidt

Patent number: 7338344Abstract: A completely automated apparatus for verifying the identity and geometry of drill bits, re-sharpening the cutting tip of a drill bit and re-positioning a locating ring upon the shank portion of the drill bit subsequent to the re-sharpening of the cutting tip thereof. The apparatus comprises a housing having a pair of cassette trays, a pair of grinding assemblies, a pair of optical assemblies, a pair of primary cleaning assemblies, a pair of secondary cleaning assemblies, a pair of inversion assemblies, a pair of workhead assemblies, a bumping assembly, and a loader assembly attached thereto. The workhead and loader assemblies are used to transport drill bits between the cassette trays and other assemblies in a selected sequence which is controlled and coordinated by a programmable control device. The control device is electrically interfaced to each of the assemblies and allows the cutting tip re-sharpening and locating ring re-positioning processes to be conducted simultaneously on at least two drill bits.Type: GrantFiled: October 4, 2005Date of Patent: March 4, 2008Inventors: Paul D Mortell, Chi Hoang, David M.

Patent number: 7200626Abstract: A method is provided to verify a database copy of a primary database which has been replicated. A secondary physically consistent copy of the primary database is put in a state of quiesce while the primary database is allowed to resume update activity. The consistent copy, in a state of quiesce, can be used for database maintenance activities or as a recovery source should the primary database be damaged, but the consistent copy is first checked for integrity by using a Verify option before such recovery source is utilized.Type: GrantFiled: January 22, 2004Date of Patent: April 3, 2007Assignee: Unisys CorporationInventors: Courtney Chi Hoang, Patricia Jean Keller, Alma Navarro de Jesus, Donald Ralph Hart
