Publication number: 20240169596Abstract: An encoding method, a decoding method, and a device for point cloud compression are provided. The encoding method includes the following. Point cloud data corresponding to a first frame is obtained, and is distinguished into a global point cloud set and at least one object point cloud set according to a reference frame. The object point cloud set corresponds to at least one reference object point cloud set. A global dynamic model corresponding to the global point cloud set is calculated and an object dynamic model corresponding to the object point cloud set is calculated. A bitstream is generated. The bitstream includes the global point cloud set, the global dynamic model corresponding to the global point cloud set, a serial number of each object point in the reference object point cloud set, and the object dynamic model corresponding to the object point cloud set.Type: ApplicationFiled: November 17, 2022Publication date: May 23, 2024Applicant: Industrial Technology Research InstituteInventors: Sheng-Po Wang, Jie-Ru Lin, Ching-Chieh Lin, Chun-Lung Lin

Publication number: 20240107414Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for switching a secondary cell to a primary cell. A user equipment (UE) monitors a first radio condition of the UE for beams of a primary cell and a second radio condition for beams of one or more secondary cells configured for the UE in carrier aggregation. The UE transmits a request to configure a candidate beam of at least one candidate secondary cell as a new primary cell in response to the first radio condition not satisfying a first threshold and the second radio condition for the at least one candidate secondary cell satisfying a second threshold. A base station determines to reconfigure at least one secondary cell as the new primary cell. The base station and the UE perform a handover of the UE to the new primary cell.Type: ApplicationFiled: September 23, 2022Publication date: March 28, 2024Inventors: Yu-Chieh HUANG, Kuhn-Chang LIN, Jen-Chun CHANG, Wen-Hsin HSIA, Chia-Jou LU, Sheng-Chih WANG, Chenghsin LIN, Yeong Leong CHOO, Chun-Hsiang CHIU, Chihhung HSIEH, Kai-Chun CHENG, Chung Wei LIN

Patent number: 10364162Abstract: A system and a method for treating salt-containing glycerin wastewater are provided, wherein the system for treating the salt-containing glycerin wastewater includes a mixing tank, a filtering device, a distillation column, and a water supply device. The mixing tank is adapted to mix salt-containing glycerin wastewater with a concentrated hydrochloric acid to obtain a mixture. The filtering device communicates with the mixing tank and filters the mixture to obtain an acidic filtrate and a precipitated salt. The distillation column communicates with the filtering device and receives the acidic filtrate from the filtering device. The water supply device supplies water to the acidic filtrate. The system and method for treating the salt-containing glycerin wastewater can effectively recycle hydrochloric acid.Type: GrantFiled: August 9, 2017Date of Patent: July 30, 2019Assignees: National Tsing Hua University, Chang Chun Plastics Co., Ltd., Chang Chun Petrochemical Co., Ltd.Inventors: Shih-Cheng Chuang, Shi-Shang Jang, David S. H. Wong, Sheng-Chieh Wang, En-Ko Lee

Patent number: 9979527Abstract: A communications apparatus includes a radio transceiver and a processor. The radio transceiver receives a plurality of feedback messages from a peer device. The feedback messages are transmitted by the peer device to indicate a result of UL data transmission. The processor analyzes content of the feedback messages to determine a preferred retransmission type of the peer device and records the preferred retransmission type of the peer device in a memory device. When the radio transceiver receives a first UL grant message indicating transmission of a first UL data and the processor determines that a forthcoming first feedback message corresponding to the transmission of the first UL data is unable to be received, the processor determines whether to retransmit the first UL data according to the preferred retransmission type of the peer device.Type: GrantFiled: August 17, 2015Date of Patent: May 22, 2018Assignee: MEDIATEK INC.Inventors: Ming-Fong Jhang, Yu-Cheng Chen, Sheng-Chieh Wang, Yu-Ting Yao

Publication number: 20170280507Abstract: A method of minimizing service degradation caused by other-SIM-occupancy of a DSDS or MSMS UE under carrier aggregation is proposed. A UE performs CC selection from the multiple CCs associated with a first SIM to suffer from other-SIM-occupancy to minimize potential service degradation. In a first option, the UE selects one or more CCs that are relatively harmless from other-SIM-occupancy to share HW resource with CCs associated with other SIMs. In a second option, the UE schedules other-SIM-occupancy on more than one CCs of the first SIM to reduce the frequency and duration of the other-SIM-occupancy affected to each chosen CC of the first SIM.Type: ApplicationFiled: November 19, 2015Publication date: September 28, 2017Inventor: Sheng-Chieh WANG
