Patent number: 10397901Abstract: The present application provide a resource allocation method, an access point, and a station. The method includes: determining a resource allocation sequence of N stations in a wireless local area network and a position of a resource allocated to each station in the N stations; determining resource allocation information according to the resource allocation sequence of the N stations and the position of the resource allocated to each station in the N stations, where the resource allocation information is used to reflect a relative position of the resource allocated to each station in the N stations; and sending resource indication information, so that each station in the N stations obtains, according to the resource indication information, the position of the resource allocated to each station. The method utilizes redundancy between indication information of different stations, so signaling overheads of resource indication information can be reduced.Type: GrantFiled: February 27, 2017Date of Patent: August 27, 2019Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Weimin Wu, Jun Lou, Shanshan Gong, Xun Yang, Sheng Liu

Patent number: 9580834Abstract: In some embodiments, the present disclosure pertains to methods of growing chalcogen-linked metallic films on a surface in a chamber. In some embodiments, the method comprises placing a metal source and a chalcogen source in the chamber, and gradually heating the chamber, where the heating leads to the chemical vapor deposition of the chalcogen source and the metal source onto the surface, and facilitates the growth of the chalcogen-linked metallic film from the chalcogen source and the metal source on the surface. In some embodiments, the chalcogen source comprises sulfur, and the metal source comprises molybdenum trioxide. In some embodiments, the growth of the chalcogen-linked metallic film occurs by formation of nucleation sites on the surface, where the nucleation sites merge to form the chalcogen-linked metallic film. In some embodiments, the formed chalcogen-linked metallic film includes MoS2.Type: GrantFiled: March 11, 2014Date of Patent: February 28, 2017Assignee: WILLIAM MARSH RICE UNIVERSITYInventors: Sina Najmaei, Zheng Liu, Pulickel M.

Patent number: 8460428Abstract: In various embodiments, methods for synthesizing single-crystalline zero-valent metal nanorings, such as single-crystalline copper nanorings, are described herein. The methods include providing a solution containing a metal cation, a complexing agent bound to the metal cation, thereby forming a metal complex that is at least partially soluble in the solution, and a reducing agent operable for reducing the metal complex to a zero-valent metal and then heating the solution for a sufficient time and at a sufficient temperature until zero-valent metal nanorings form. The solution may be an aqueous solution in an embodiment. Single-crystalline metal nanorings produced by the methods described herein may have a diameter less than about 100 ?m and a wall thickness between about 10 nm and about 500 nm.Type: GrantFiled: April 30, 2010Date of Patent: June 11, 2013Assignee: William Marsh Rice UniversityInventors: Jun Lou, Yongjie Zhan

Patent number: 8058613Abstract: The present disclosure describes micromechanical devices and methods for using such devices for characterizing a material's strength. The micromechanical devices include an anchor pad, a top shuttle platform, a nanoindenter in movable contact with the top shuttle platform and at least two sample stage shuttles. The nanoindenter applies a compression force to the top shuttle platform, and the at least two sample stage shuttles move apart in response to the compression force. Each of the at least two sample stage shuttles is connected to the top shuttle platform and to the anchor pad by at least one inclined beam. Methods for using the devices include connecting a sample between the at least two sample stage shuttles and applying a compression force to the top shuttle platform. Application of the compression force to the top shuttle platform results in a tensile force being applied to the sample. Measuring a tip displacement of the nanoindenter is correlated with the sample's strength.Type: GrantFiled: October 28, 2009Date of Patent: November 15, 2011Assignee: William Marsh Rice UniversityInventors: Jun Lou, Yogeeswaran Ganesan, Yang Lu, Cheng Peng

Patent number: 5157831Abstract: A process for preparing an electrical connector from a glass plug, a rigid metal shell, and at least one pin conductor is disclosed.The glass plug is made by mixing glass powder with binder, forming a green body, debindering the green body, and heating the debindered green body.The metal shell and metal pin conductor(s) are first cleaned by heating them in a hydrogen-containing atmosphere, and thereafter forming an oxide coating on their surfaces.An assembly is then formed from the rigid metal shell, the glass plug, and the pin conductor(s). This assembly is then heat treated to form the electrical connector.Type: GrantFiled: December 20, 1991Date of Patent: October 27, 1992Assignees: Alfred University, Howard J.
