Patent number: 9206910Abstract: A gate valve has a body, the body having a cavity and a flow passage intersecting the cavity. A seat fabricated from a ceramic and/or hardfacing alloy matrix composite substrate is mounted to the body at the intersection of the flow passage and the cavity. A gate fabricated from a ceramic and/or hardfacing alloy matrix composite substrate is installed at the cavity and has an engaging face that slidingly engages the seat while the gate is being moved between open and closed positions. The engaging faces of the gate and seats are coated with a low-friction material to facilitate sliding. The ceramic and/or hardfacing alloy matrix composite substrate construction of the gate and seats with low friction engaging surfaces enhances the gate valve's bearing stress capacity.Type: GrantFiled: April 12, 2011Date of Patent: December 8, 2015Assignee: Vetco Gray Inc.Inventors: Jon Bonner Kahn, Fei Tang

Publication number: 20150021547Abstract: A GaN based LED epitaxial structure and a method for manufacturing the same. The GaN based LED epitaxial structure may include: a substrate; and a GaN based LED epitaxial structure grown on the substrate, wherein the substrate is a substrate containing a photoluminescence fluorescent material. The photoelectric efficiency of the LED epitaxial structure is enhanced and the amount of heat generated from a device is reduced by utilizing a rare earth element doped Re3Al5O12 substrate; since the LED epitaxial structure takes a fluorescence material as a substrate, a direct white light emission may be implemented by such an LED chip manufactured by the epitaxial structure, so as to simplify the manufacturing procedure of the white light LED light source and to reduce production cost. The defect density of the epitaxial structure is reduced by firstly epitaxial growing, patterning the substrate and then laterally growing a GaN based epitaxial structure.Type: ApplicationFiled: July 18, 2014Publication date: January 22, 2015Inventors: Yongge CAO, Zhuguang LIU, Zhonghua DENG, Jian CHEN, Junting LI, Binjie FEI, Wang GUO, Fei TANG, Qiufeng HUANG, Xuanyi YUAN

Publication number: 20140039979Abstract: A system and method for demand forecasting is provided. The system includes a computer system and a demand forecasting engine executed by the computer system. The demand forecasting engine permits inventory management and price optimization, with improved prediction accuracy. The system includes a nonlinear time series model which is able to simulate the market trend of a certain product in the past and make a demand forecast for the future. The system provides initial estimates for new products in a new season, and is self-adjusting with limited data points in the beginning of the season. In this way, the system provides solutions for demand forecasting of old and new products. Furthermore, pricing optimization solutions (e.g., Markov decision processed (MDP) based, etc.) can be built on the basis of the demand forecasting solutions. The system is applicable to many marketing-related problems and is particularly reliable for products which follow a certain cycle.Type: ApplicationFiled: August 1, 2013Publication date: February 6, 2014Applicant: Opera Solutions, LLCInventors: Bo Zhang, Fei Tang, Jun Wang, Shoupeng Peng, Zhangle Wang

Publication number: 20110158651Abstract: In the field of photonic integrated communication, a method and an apparatus for filtering locking are provided, so as to solve the problem in the conventional wavelength locking technology that any increase of the wave number also incurs increases in costs and circuit complexity, and it is difficult to extract dithered information. The method and apparatus for filtering locking employ a centralized wavelength locking method of injecting a single dither to a Photonic Integrated Device (PID)/Photonic Integrated Circuit (PIC), thereby reducing circuit board area and control circuit complexity. A weak dither signal can be accurately extracted by means of a combination of analog filtering and digital filtering. The technical solution is appropriate for use in photonic integrated systems in which two or more PID/PIC chips with multi-wavelength modules are cascaded.Type: ApplicationFiled: March 9, 2011Publication date: June 30, 2011Applicant: Huawei Technologies Co., Ltd.
