Patent number: 11959743Abstract: A dimensionless kinematics calibration method based on a virtual point and a related apparatus thereof. The method comprises: establishing a kinematics model of a motion mechanism, and arranging a plurality of virtual points at a tail end of the motion mechanism to establish a dimensionless kinematics model and a dimensionless error model; converting a measurement coordinate system into a motion mechanism coordinate system, acquiring a rotation matrix and a translation matrix of a target virtual point measured by the measurement device, and calculating actual coordinates of all virtual points to obtain a measured value of the dimensionless kinematics model; calculating a theoretical value of the dimensionless kinematics model according to a spatial relationship between a reflecting head and the tail end of the motion mechanism; and optimizing the dimensionless error model according to the measured value and the theoretical value to obtain a calibration result.Type: GrantFiled: October 7, 2023Date of Patent: April 16, 2024Assignee: GUANGDONG UNIVERSITY OF TECHNOLOGYInventors: Jian Gao, Disai Chen, Yuheng Luo, Lanyu Zhang, Zhuojun Zheng, Guoqing Wu, Xin Chen

Patent number: 11926709Abstract: A method for recycling waste polyester, in particular to a method for recycling waste polyester by a modified alcoholysis method to recycle waste polyester to prepare dimethyl terephthalate (DMT), is provided and belongs to waste polyester recycling technology field. The waste polyester after dewatering and deoxygenation treatment is used as a raw material, in the step of feeding in melted state the alcoholysis agent is added in the melted waste polyester for preliminary alcoholysis, and the alcoholysis agent is ethylene glycol. On one hand, alcoholysis reaction occurs when the waste polyester raw material are melted, and at the same time, the viscosity of the melted material is reduced. Thus, the melted material remains melted at the alcoholysis temperature and is not easy to solidify again after entering the alcoholysis tank, ensuring that the alcoholysis is carried out under homogeneous conditions.Type: GrantFiled: September 7, 2020Date of Patent: March 12, 2024Inventors: Huayu Fang, Enbin Zhu, Dubin Wang, Guoqing Yu, Jincheng Chen, Tianyuan Li, Jiantong Wu, Jianhua Chen, Shengyao Lin

Patent number: 11930381Abstract: Some aspects of this disclosure include apparatuses and methods for implementing backup link establishment and operation for multi-link wireless communication networks such as a wireless local area network (WLAN). Some aspects relate to an electronic device including a transceiver configured to communicate over a wireless network and a processor communicatively coupled to the transceiver. The processor receives a message including information associated with a backup link from a second electronic device. The processor further receives data associated with data traffic from the second electronic device on a primary link of the wireless network. In response to a quality of the primary link being below a threshold, the processor receives a notification frame from the second electronic device on the backup link and receives additional data associated with the data traffic from the second electronic device on the backup link or on an other link informed by the notification frame.Type: GrantFiled: June 3, 2021Date of Patent: March 12, 2024Assignee: Apple Inc.Inventors: Qi Wang, Yong Liu, Jinjing Jiang, Jarkko L.

Patent number: 11924898Abstract: Some embodiments include utilizing a multilink media access control (MAC) address structure to support multilink devices (MLDs) that can operate concurrently in more than one link such as extremely high throughput (EHT) access points (APs) and EHT stations (STA), where the multilink MAC address structure is compatible with legacy devices. An EHT AP can utilize a multilink basic service set (BSS) identification (BSSID) MAC address to communicate with an EHT STA identified by a multilink MAC address. Values of the multilink BSSID and the multilink MAC address of the EHT STA are independent of which of the multiple links are used in the communication. In addition, to utilizing a multilink BSSID, the EHT AP can also support unique link-specific MAC addresses to concurrently support legacy and MLD stations. The EHT STA can also utilize unique link-specific MAC addresses that can be different than the EHT AP's link-specific MAC addresses.Type: GrantFiled: January 3, 2022Date of Patent: March 5, 2024Assignee: Apple Inc.Inventors: Jarkko L.

Patent number: 9869006Abstract: This invention disclosed a method for preparing the ultrafine intermetallic particles reinforced metal matrix composites (MMC). The particle size of ultrafine intermetallic particles is about 0.01˜5 ?m. In this method, intermetallic particles and metal matrix were first ball milled together to get the mixed powder. Then, powders were cold-pressed then vacuum melting with metals to prepare the reinforced metal matrix composites materials. The intermetallic particles addition amount in this is 1˜30 wt %. This invention improve the dispersion properties of intermetallic particles while increase the particle/matrix interface strength. The ultrafine intermetallic particles reinforced MMC shows the very good performance with good ductility and strength.Type: GrantFiled: May 31, 2013Date of Patent: January 16, 2018Assignee: BEIHANG UNIVERSITYInventors: Guoqing Wu, Qingqing Zhang, Zhiyan Li, Zheng Huang

Patent number: 9308579Abstract: This invention publishes a method to prepare CaO-based ceramic cores used in investment casting applications. This method claims to use the rare earth oxide to coat the CaO core surface; later the coated cores are shaped then sintered to get the final products. CaO based core was made by 5˜15 wt % plasticizer, 0.001˜20 wt % mineralizer and the rare earth-coated CaO powders to balance for total 100%. This preparation method can solve the CaO core water absorption problems during core manufacturing, shipping and storage process while improve the core chemical inertness and mechanical properties.Type: GrantFiled: May 31, 2013Date of Patent: April 12, 2016Assignee: BEIHANG UNIVERSITYInventors: Guoqing Wu, Pengpeng Zhou, Jiaqi Zhao, Hai Nan
