Patent number: 10964340Abstract: A recording head has a near-field transducer proximate a media-facing surface of the recording head. The near-field transducer extends a first distance away from the media-facing surface. A waveguide overlaps and delivers light to the near-field transducer. Two subwavelength focusing mirrors are at an end of the waveguide proximate the media-facing surface and extend a second distance away from the media-facing surface that is less than the first distance. The subwavelength mirrors are on opposite crosstrack sides of the near-field transducer and separated from each other by a crosstrack gap. The subwavelength focusing mirrors each include a first material at the media-facing surface; and a second material facing away from the media facing surface and in contact with the first material. The second material includes a plasmonic material, and the first material is more mechanically robust than the second material.Type: GrantFiled: April 22, 2020Date of Patent: March 30, 2021Assignee: Seagate Technology LLCInventors: Weibin Chen, Nan Zhou, Ruoxi Yang, Michael Allen Seigler

Publication number: 20200378255Abstract: An internally injected replacement support room-type coal pillar recovery method is provided. During the recovery the room-type coal pillars with an aspect ratio greater than 0.6 are divided into two parts: reserved coal pillars and pre-mined coal pillars. After the mining of the pre-mined coal pillars, a cemented filling material is injected into a goaf surrounded by the reserved coal pillars, and is stabilized to replace the coal pillars for support, and the reserved coal pillars are recovered. A mechanical model of the reserved coal pillars in a support overburden stage is established based on the Winkler beam theory, to obtain displacement and stress conditions of a roof of the reserved coal pillar in a support stage. A theoretical reserve-width of the reserved coal pillars is obtained according to a first strength theory of the roof and a criterion of ultimate strength of the reserved coal pillars.Type: ApplicationFiled: February 22, 2019Publication date: December 3, 2020Applicant: CHINA UNIVERSITY OF MINING AND TECHNOLOGYInventors: Nan ZHOU, Jiaqi WANG, Jixiong ZHANG, Kai SUN, Meng LI

Patent number: 10445061Abstract: A system, method, and apparatus are provided for migrating contacts (e.g., records identifying contacts) from one domain to another. Each record includes various fields corresponding to a single contact or other entity known within the first domain. The migration process may involve configuring multiple queries from the field data, for querying the second domain or system to identify (or to attempt to identify) matching entities known within the second domain. One or more exact queries may be configured to identify specific entities within the second domain, based on entity-specific data, for example. Other queries may be more general and may match multiple entities known within the second domain. For records for which no exact query identifies an entity, one or more general queries may be executed to identify multiple entities, which may be subsequently ranked based on the likelihood that they are the entity that corresponds to the record.Type: GrantFiled: November 28, 2016Date of Patent: October 15, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Kancheng Cao, Dakan Wang, Bill Bi Lun Kuang, Gururaj Seetharama, Manoj Rameshchandra Thakur, Jan Schellenberger, Nan Zhou
