Patent number: 12316361Abstract: The present invention discloses a signal receiving apparatus having phase compensation mechanism. A first and a second receiving path of a receiving circuit perform frequency down-conversion and analog-to-digital conversion on an input signal to generate a first and a second receiving signals. The first and the second receiving paths uses a RF training signal generated by a RF training signal generation circuit as the input signal when a phase compensation is performed, and use a data signal from an antenna circuit as the input signal when a beamforming signal receiving is performed. A phase difference calculation circuit of the receiving circuit performs cross-correlation operation on the first and the second receiving signals to generate a compensation signal according to a phase difference between the first and the second receiving paths.Type: GrantFiled: December 6, 2022Date of Patent: May 27, 2025Assignee: REALTEK SEMICONDUCTOR CORPORATIONInventors: Hao-Han Hsu, Chuan-Hu Lin, Chung-Yao Chang

Patent number: 12196042Abstract: Provided is a novel wear-resistant and collision-resistant polycrystalline diamond compact (PDC) drill bit with rostriform teeth and a plurality of blades, including an upper joint and a drill matrix. The PDC drill bit with rostriform teeth and a plurality of blades breaks rocks jointly by the primary teeth by way of penetration-splitting and the secondary teeth by way of shearing, so that the torque needed to break the rocks is greatly reduced. The design of the plurality of blades balances force distribution between rocks and blades at a shaft bottom, so that the abrasion loss of the teeth within a unit time is reduced. The present invention solves the technical problems in the prior art that cutting positions are abraded, and the teeth are fed slowly and are unreasonably distributed.Type: GrantFiled: January 2, 2024Date of Patent: January 14, 2025Assignee: Southwest Petroleum UniversityInventors: Tiejun Lin, Chengsong Yang, Hao Yu, Jianhua Guo, Jiachang Nie, Chengxiu Yu, Yuheng Tuo, Hao Han, Xin Zeng, Zelin Zhu, Ruiqi Shen, Wenle Yu, Zeqian Ren
